It’s available in clear and bronze finishes, making it suitable for a range of outdoor and DIY projects. This impact-resistant sheet is easy to work with and offers a professional, long-lasting finish — backed by a 10-year warranty. You can purchase it in full sheets or have it cut to size to suit your specific needs.\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\nAvailable in clear and bronze finishes\n\nLightweight and impact-resistant\n\nUV resistant for long-term durability\n\nReduces the risk of condensation\n\nEasy to clean and largely self-cleaning\n\nCovered by a 10-year manufacturer’s warranty\n\n\u003ch3\u003eIdeal For\u003c\/h3\u003e\n\nGreenhouses\n\nSun screens\n\nSwimming pool covers\n\nVertical panels\n\nPlant houses\n\nDIY glazing and roofing projects\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\nFor optimal performance, always ensure the UV-protected side (clearly marked) is facing outward when installing. Sheets must be installed with a minimum roof pitch of 10° to allow proper water drainage.\n\nThe flutes of the sheet must run vertically—from the top to the bottom of the slope—not side to side. Sheets cannot be joined from top to bottom. When sealing or flashing, always use low modulus neutral cure sealant and cross-linked butyl flashing tape to maintain weather resistance and ensure longevity.\n\n\u003ch3\u003eCutting and Shaping\u003c\/h3\u003e\n\nCorotherm 10mm is easy to cut and won’t crack or shatter when handled properly. For straight cuts along the flutes, a sharp utility knife works well. When cutting across the flutes, a fine-toothed saw is recommended. For any curved cuts, a fine-toothed jigsaw is the best tool for the job.\n\n\u003ch3\u003eThermal Expansion\u003c\/h3\u003e\n\nPolycarbonate expands and contracts with changes in temperature. To prevent buckling or warping, leave adequate expansion gaps when fitting the sheets. Allow a gap at the top end, and when drilling fixing holes, leave at least 3mm of space around each one. Never over-tighten or clamp the sheets—leave them room to move.\n\n\u003ch3\u003eCleaning and Maintenance\u003c\/h3\u003e\n\nCorotherm can be cleaned quickly and easily using lukewarm soapy water and a soft cloth or sponge. Avoid using abrasive cleaners, sharp tools, or anything with a high alkaline content, as these may damage the surface. Thanks to its UV-resistant coating, the sheet is also largely self-cleaning.\n\n\u003ch3\u003e10-Year Warranty\u003c\/h3\u003e\n\nThis product comes with a 10-year warranty that covers manufacturing defects under normal weather conditions. If the sheet fails due to a defect within this period, it will be replaced free of charge. Please note, the warranty is only valid if the product is installed and maintained according to the manufacturer’s instructions. The warranty does not cover costs related to re-installation or any consequential damage.\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003ch4\u003e1. Can I use Corotherm 10mm Twinwall for roofing?\u003c\/h4\u003e\nYes! Unlike the 4mm version, the 10mm Twinwall Corotherm sheet is suitable for roofing as well as glazing. Just ensure you install it with the correct pitch and follow the manufacturer’s guidelines.\n\n\u003ch4\u003e2. Which way should the flutes run during installation?\u003c\/h4\u003e\nThe flutes must run vertically—from the top to the bottom of the slope—to allow proper water drainage. Do not install them side-to-side, as this can cause water to pool and affect the sheet’s structural integrity.\n\n\u003ch4\u003e3. How do I maintain the 10-year warranty?\u003c\/h4\u003e\nTo keep your warranty valid, the sheet must be fixed and maintained according to Ariel Plastics' instructions. That includes using the correct sealants, allowing for expansion, and cleaning with appropriate materials. The warranty does not cover installation errors or damages caused by incorrect use.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca

Bronze 16mm Triplewall Polycarbonate Roofing Sheet - Ariel Plastics","description":"The Corotherm 16mm Triplewall sheet is a strong yet lightweight polycarbonate solution ideal for roofing and vertical glazing projects. Designed for excellent durability and insulation, this triplewall sheet comes in clear, bronze, and opal finishes to suit a variety of styles and applications. Whether you're building a conservatory, carport, or porch, this versatile sheet offers reliable weather protection and light diffusion. It is available in full sheets or can be cut to size, and comes with a 10-year warranty for peace of mind.\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\nAvailable in clear, bronze, and opal finishes\n\nLightweight and impact-resistant\n\nUV-protected for long-term performance\n\nHelps minimise condensation\n\nSelf-cleaning surface with low maintenance\n\nCovered by a 10-year manufacturer’s warranty\n\n\u003ch3\u003ePerfect For\u003c\/h3\u003e\n\nPorches\n\nCanopies\n\nCarports\n\nConservatories\n\nLean-to roofs\n\nVertical glazing and cladding projects\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\nBefore installation, be sure the UV-protected side (clearly marked) is facing outward to protect the sheet from sun damage. For proper drainage, the roof should be pitched at a minimum slope of 10°. The sheet's flutes must run vertically from the top to the bottom of the slope—never side to side—as this ensures correct drainage and structural integrity. Sheets cannot be joined vertically from top to bottom.\n\nOnly use low modulus neutral cure sealant and cross-linked butyl flashing tape to ensure weather resistance and longevity.\n\n\u003ch3\u003eCutting and Shaping\u003c\/h3\u003e\n\nCorotherm 16mm Triplewall sheets are simple to cut and won’t crack or shatter. For cuts parallel to the flutes, a sharp utility knife works well. For cross cuts, use a fine-toothed saw, and if you're working with curves, a fine-toothed jigsaw is the most suitable tool for the job.\n\n\u003ch3\u003eThermal Expansion\u003c\/h3\u003e\n\nAs with all polycarbonate materials, thermal expansion must be accounted for during installation. Leave adequate gaps at the top of the sheet, and when drilling fixing holes, allow at least 3mm around each hole for movement. Do not clamp or overtighten the sheets—this will restrict thermal movement and can lead to damage.\n\n\u003ch3\u003eCleaning and Maintenance\u003c\/h3\u003e\n\nCleaning your Corotherm sheet is easy. Simply use lukewarm soapy water and a soft sponge or cloth. Avoid abrasive cleaners, brushes, or high-alkaline solutions as they can scratch or damage the sheet. The UV-protected surface also helps keep the sheet cleaner for longer, reducing maintenance needs.\n\n\u003ch3\u003e10-Year Warranty\u003c\/h3\u003e\n\nCorotherm 16mm Triplewall comes with a 10-year warranty against manufacturing defects under normal weather conditions. If a fault develops due to a manufacturing issue within this timeframe, a replacement will be provided free of charge. However, the warranty is only valid if the product is installed and maintained according to the manufacturer’s instructions. It does not cover reinstallation costs or consequential damage.\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003ch4\u003e1. Is the 16mm Triplewall Corotherm suitable for roofing?\u003c\/h4\u003e\nYes, this product is specifically designed for roofing as well as vertical glazing. It’s ideal for porches, conservatories, carports, and similar structures thanks to its strength and insulation properties.\n\n\u003ch4\u003e2. How should the sheet be installed to allow proper water drainage?\u003c\/h4\u003e\nMake sure the sheet is installed at a roof pitch of at least 10°, with the flutes running vertically from top to bottom. This ensures effective water runoff and structural integrity.\n\n\u003ch4\u003e3. How do I maintain the sheet to ensure the warranty remains valid?\u003c\/h4\u003e\nTo maintain warranty coverage, install the sheet according to the manufacturer’s instructions using only the recommended sealants and fixings.

Bronze 25mm 7Xwall Polycarbonate Roofing Sheet - Ariel Plastics","description":"The Corotherm 25mm 7Xwall is a premium-grade, lightweight polycarbonate sheet designed for roofing and vertical glazing applications. With its multiwall structure and U-value of 1.4W\/m²K, it offers excellent thermal insulation while still being easy to handle and install. Whether you’re working on a conservatory, canopy, or lean-to roof, this sheet delivers durability, energy efficiency, and a clean modern look.\n\nAvailable in a range of finishes including clear, bronze, opal, as well as dual tints like bronze opal and heatguard opal, Corotherm 25mm 7Xwall can be supplied in full sheets or cut to size. It’s also backed by a reassuring 10-year warranty.\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\nAvailable in clear, bronze, opal, bronze opal, and heatguard opal\n\nLightweight and impact-resistant\n\nUV protected for long-lasting performance\n\nExcellent thermal insulation (U-value: 1.4W\/m²K)\n\nHelps minimise condensation\n\nSelf-cleaning surface for low maintenance\n\nComes with a 10-year manufacturer’s warranty\n\n\u003ch3\u003eIdeal For\u003c\/h3\u003e\n\nPorches\n\nCanopies\n\nCarports\n\nConservatories\n\nLean-to roofs\n\nVertical glazing and cladding projects\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\nWhen installing, ensure the UV-protected side (clearly marked on the sheet) is facing outwards to protect it from sun damage. For optimal drainage, your roof must have a minimum slope of 10°. The sheet’s flutes should always run vertically—from the top of the slope to the bottom. Never install with the flutes running sideways, and note that sheets cannot be joined vertically (top to bottom).\n\nTo maintain proper waterproofing, only use low modulus neutral cure sealant and cross-linked butyl flashing tape during installation.\n\n\u003ch3\u003eCutting and Shaping\u003c\/h3\u003e\n\nCutting Corotherm 25mm 7Xwall is simple and safe. It won’t crack or shatter when cut properly. Use a sharp utility knife for cuts along the direction of the flutes. For cuts across the flutes, a fine-toothed saw works best, while a fine-toothed jigsaw is ideal for any curved shapes.\n\n\u003ch3\u003eThermal Expansion\u003c\/h3\u003e\n\nAs with any polycarbonate product, you’ll need to allow for thermal expansion. Leave a gap at the top of the sheet during installation, and always drill fixing holes with an extra 3mm of space around each one. Avoid overtightening or clamping the sheets too tightly to ensure they can expand and contract naturally with temperature changes.\n\n\u003ch3\u003eCleaning and Maintenance\u003c\/h3\u003e\n\nCleaning your Corotherm sheet is easy. Just use lukewarm soapy water with a soft cloth or sponge. Avoid harsh brushes, sharp tools, or abrasive or high-alkaline cleaning products that could damage the surface. Thanks to its UV-resistant and smooth surface, the sheet is largely self-cleaning.\n\n\u003ch3\u003e10-Year Warranty\u003c\/h3\u003e\n\nThe Corotherm 25mm 7Xwall comes with a 10-year warranty covering any failure due to manufacturing defects under normal weather conditions. If an issue arises within this period, a replacement sheet will be provided free of charge. However, the sheet must be installed and maintained according to the manufacturer's instructions for the warranty to remain valid. Please note that the warranty does not cover reinstallation or any related damage.\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003ch4\u003e1. What makes the 25mm 7Xwall better for insulation?\u003c\/h4\u003e\nIts triple-wall, 7X structure provides excellent thermal insulation with a U-value of 1.4W\/m²K. This means it helps retain heat better than thinner sheets, making it a great choice for conservatories and enclosed spaces.\n\n\u003ch4\u003e2. Can I install this sheet for a flat roof?\u003c\/h4\u003e\nNo, flat installation is not recommended. The roof should have at least a 10° pitch to allow water to run off properly. Installing it flat can lead to water pooling and reduce the lifespan of the sheet.\n\n\u003ch4\u003e3. Is heatguard opal different from regular opal?\u003c\/h4\u003e\nYes, heatguard opal is a dual-tint option designed to reflect more solar heat while still allowing light through. It’s ideal for spaces where you want to reduce heat build-up, like sunrooms or greenhouses.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/roofing-supplies\"\u003eroofing supplies\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eBrowse more \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/polycarbonate-roof-sheets\"\u003ecorotherm roof sheets\u003c\/a\u003e available online.\u003c\/p\u003e","brand":"Ariel Plastics","offers":[{"title":"Bronze \/ 2000mm x 1050mm","offer_id":50804924678486,"sku":"118663","price":69.29,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2000mm x 1600mm","offer_id":50804924711254,"sku":"118668","price":105.57,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2000mm x 2100mm","offer_id":50804924744022,"sku":"118673","price":138.57,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2000mm x 700mm","offer_id":50804924776790,"sku":"118648","price":46.19,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2000mm x 800mm","offer_id":50804924809558,"sku":"118653","price":52.78,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2000mm x 900mm","offer_id":50804924842326,"sku":"118658","price":59.39,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2500mm x 1050mm","offer_id":50804924875094,"sku":"118664","price":86.61,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2500mm x 1600mm","offer_id":50804924907862,"sku":"118669","price":131.96,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2500mm x 2100mm","offer_id":50804924940630,"sku":"118674","price":173.22,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2500mm x 700mm","offer_id":50804924973398,"sku":"118649","price":57.74,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2500mm x 800mm","offer_id":50804925006166,"sku":"118654","price":65.98,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 2500mm x 900mm","offer_id":50804925038934,"sku":"118659","price":74.22,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 3000mm x 1050mm","offer_id":50804925071702,"sku":"118665","price":103.92,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 3000mm x 1600mm","offer_id":50804925104470,"sku":"118670","price":158.37,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 3000mm x 2100mm","offer_id":50804925137238,"sku":"118675","price":207.85,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 3000mm x 700mm","offer_id":50804925170006,"sku":"118650","price":69.29,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 3000mm x 800mm","offer_id":50804925202774,"sku":"118655","price":79.18,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 3000mm x 900mm","offer_id":50804925235542,"sku":"118660","price":89.08,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 4000mm x 1050mm","offer_id":50804925268310,"sku":"118666","price":138.57,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 4000mm x 1600mm","offer_id":50804925301078,"sku":"118671","price":211.15,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 4000mm x 2100mm","offer_id":50804925333846,"sku":"118676","price":277.14,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 4000mm x 700mm","offer_id":50804925366614,"sku":"118651","price":92.38,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 4000mm x 800mm","offer_id":50804925399382,"sku":"118656","price":105.57,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 4000mm x 900mm","offer_id":50804925432150,"sku":"118661","price":118.79,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 6000mm x 1050mm","offer_id":50804925464918,"sku":"118667","price":207.85,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 6000mm x 1600mm","offer_id":50804925497686,"sku":"118672","price":316.73,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 6000mm x 2100mm","offer_id":50804925530454,"sku":"118677","price":415.72,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 6000mm x 700mm","offer_id":50804925563222,"sku":"118652","price":138.57,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 6000mm x 800mm","offer_id":50804925595990,"sku":"118657","price":158.37,"currency_code":"GBP","in_stock":true},{"title":"Bronze \/ 6000mm x 900mm","offer_id":50804925628758,"sku":"118662","price":178.17,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/4509\/4998\/files\/corotherm-bronze-25mm-7xwall-polycarbonate-roofing-sheet-ariel-plastics-5532439.jpg?v=1772662171"},{"product_id":"corotherm-clear-16mm-triplewall-polycarbonate-roofing-sheet-ariel-plastics","title":"Corotherm Clear 16mm Triplewall Polycarbonate Roofing Sheet -

This protects the material from sun damage and helps maintain performance over time.\n\nTo ensure proper drainage, install the sheets at a minimum roof pitch of 10°. The internal flutes should run vertically from the top to the bottom of the slope—not side to side—as this supports structural integrity and allows water to drain effectively. Sheets cannot be joined vertically from top to bottom.\n\nFor sealing and weatherproofing, only use low modulus neutral cure sealants and cross-linked butyl flashing tape. These materials ensure durability and prevent water ingress.\n\n\u003ch3\u003eCutting and Shaping\u003c\/h3\u003e\nCorotherm Triplewall sheets are easy to handle and won’t crack or shatter during cutting. For cuts that run parallel to the flutes, a sharp utility knife will work well. For cross cuts, a fine-toothed saw is best. If you’re shaping curves, a fine-toothed jigsaw provides the most precise results.\n\n\u003ch3\u003eThermal Expansion\u003c\/h3\u003e\nLike all polycarbonate materials, these sheets expand and contract with temperature changes. It’s important to allow for this movement during installation. Leave a small gap at the top of each sheet and drill fixing holes slightly larger than the fixings (at least 3mm extra around each hole). Avoid overtightening, as this can restrict expansion and cause damage.\n\n\u003ch3\u003eCleaning and Maintenance\u003c\/h3\u003e\nKeeping your Corotherm sheet clean is simple. Use lukewarm, soapy water and a soft cloth or sponge to remove dirt. Never use abrasive materials, harsh brushes, or high-alkaline cleaners, as they may scratch or damage the surface. The UV protection also helps repel dirt, reducing how often cleaning is needed.\n\n\u003ch3\u003e10-Year Warranty\u003c\/h3\u003e\nCorotherm 16mm Triplewall Sheets come with a 10-year warranty covering manufacturing defects under normal weather conditions. If a fault appears due to a production issue within this time frame, a free replacement will be provided.\n\nPlease note that the warranty is only valid if the sheets are installed and maintained according to the manufacturer’s guidelines. The warranty does not cover reinstallation costs or any damage resulting from incorrect installation.\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003ch4\u003e1. Is the 16mm Triplewall Corotherm suitable for roofing?\u003c\/h4\u003e Yes, absolutely. The Corotherm 16mm Triplewall sheet is specifically designed for both roofing and vertical glazing.

Opal 16mm Triplewall Polycarbonate Roofing Sheet - Ariel Plastics","description":"The Corotherm Opal 16mm Triplewall Polycarbonate Sheet from Ariel Plastics is a practical and high-performance option for a wide range of roofing and glazing needs. It combines strength and lightweight handling with excellent insulation properties, making it ideal for conservatories, carports, porches, and more.\n\nIts subtle opal finish offers a softer, diffused light transmission while still providing reliable protection against the elements. Whether you're looking to reduce glare or add privacy, the opal option is both stylish and functional. These sheets are available in full sizes or can be cut to your specifications, and every sheet is backed by a reassuring 10-year manufacturer’s warranty.\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\nAvailable in clear, bronze, and opal finishes\n\nLightweight yet tough and impact-resistant\n\nUV-protected for longer life and colour stability\n\nHelps reduce condensation build-up\n\nLow maintenance with a self-cleaning surface\n\nCovered by a 10-year manufacturer’s warranty\n\n\u003ch3\u003ePerfect For\u003c\/h3\u003e\nThis product is a great choice for:\n\nPorches\n\nCanopies\n\nCarports\n\nConservatories\n\nLean-to roofs\n\nVertical glazing or cladding projects\n\nIts versatility and performance make it suitable for both residential and light commercial applications.\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\nBefore installation, always check that the UV-protected side of the sheet is facing outwards—this is clearly labelled by the manufacturer. This ensures the sheet remains protected from sun damage over time.\n\nTo allow rainwater to drain efficiently, the roof must be pitched at a minimum of 10°. The sheet’s internal flutes should run vertically, from the top to the bottom of the slope—never sideways—as this supports structural strength and ensures proper drainage.\n\nPlease note: sheets cannot be joined vertically. For best results, use low modulus neutral cure sealants and cross-linked butyl flashing tape for sealing.\n\n\u003ch3\u003eCutting and Shaping\u003c\/h3\u003e\nWorking with Corotherm sheets is straightforward. For cuts that run along the flutes, use a sharp utility knife. If you’re cutting across the flutes, a fine-toothed saw works best. For more intricate curved shapes, a fine-toothed jigsaw will give you clean results without splintering or cracking.\n\n\u003ch3\u003eThermal Expansion\u003c\/h3\u003e\nPolycarbonate naturally expands and contracts with temperature changes, so it’s essential to account for this during installation. Leave a small gap at the top of each sheet, and when drilling, make the holes at least 3mm larger than the fixings to allow for movement.\n\nAvoid clamping the sheets too tightly or overtightening fixings, as this may cause stress and cracking over time.\n\n\u003ch3\u003eCleaning and Maintenance\u003c\/h3\u003e\nKeeping your sheet clean is simple and low effort. Use lukewarm, soapy water and a soft cloth or sponge to gently wipe away dirt or debris. Avoid abrasive products, rough brushes, and highly alkaline cleaning agents, as these can damage the surface.\n\nThe sheet’s UV protection also helps repel dirt, meaning you won’t need to clean it as frequently compared to other materials.\n\n\u003ch3\u003e10-Year Warranty\u003c\/h3\u003e\nEvery Corotherm 16mm Triplewall sheet comes with a 10-year manufacturer’s warranty covering faults due to manufacturing defects under normal weather conditions.\n\nPlease remember that the warranty is only valid if the product is installed and maintained according to the official instructions. The warranty does not cover costs for reinstallation or damage resulting from incorrect installation.\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003ch4\u003e1. What makes the opal finish different from the clear or bronze versions?\u003c\/h4\u003e The opal finish provides a **softer, diffused light**, reducing glare while still allowing natural light to pass through. It’s ideal for areas where privacy or softer lighting is desired, such as conservatories or sheltered walkways. \u003ch4\u003e2. Can I cut the sheets myself, and what tools should I use?\u003c\/h4\u003e Yes, you can easily cut the sheets at home. Use a **sharp utility knife** for cuts along the flutes and a **fine-toothed saw or jigsaw** for cross cuts or curves. Always wear protective gear when cutting and secure the sheet to prevent slipping. \u003ch4\u003e3. How do I make sure the warranty stays valid?\u003c\/h4\u003e To keep your warranty valid, follow all installation instructions provided by Ariel Plastics. Use the correct sealants and flashing materials, install with the UV side facing out, and maintain the sheet with gentle cleaning methods only—no abrasive products or high-pressure tools.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/roofing-supplies\"\u003eroofing

Clear 25mm 7Xwall Polycarbonate Roofing Sheet - Ariel Plastics","description":"The Corotherm 25mm 7Xwall sheet by Ariel Plastics is a high-performance polycarbonate roofing and glazing solution designed for energy efficiency and durability. Its advanced 7-wall structure offers superior strength and a low U-value of just 1.4W\/m²K, helping to retain heat in enclosed areas like conservatories, carports, and lean-to roofs.\n\nDespite its strength, the sheet remains lightweight and easy to handle, making it suitable for both DIY and professional installations. Its clear finish provides excellent light transmission, while a range of other tints—like bronze, opal, bronze opal, and heatguard opal—let you tailor the sheet to your project’s lighting and heat control needs.\n\nBacked by a 10-year warranty, it’s a reliable long-term investment for any roofing or glazing application.\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\nAvailable in clear, bronze, opal, bronze opal, and heatguard opal\n\nStrong yet lightweight and impact-resistant\n\nUV-protected for long-term clarity and performance\n\nExcellent thermal insulation (U-value: 1.4W\/m²K)\n\nHelps reduce condensation\n\nSelf-cleaning surface for easier maintenance\n\nSupplied with a 10-year manufacturer’s warranty\n\n\u003ch3\u003eIdeal For\u003c\/h3\u003e\nThis sheet is particularly well-suited for:\n\nPorches\n\nCanopies\n\nCarports\n\nConservatories\n\nLean-to roofs\n\nVertical glazing or cladding\n\nIts insulating properties make it especially valuable for enclosed structures where energy efficiency matters.\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\nBefore installing the sheet, make sure the UV-protected side (which is clearly marked) is facing outward to shield it from sun damage. The roof should be installed at a minimum pitch of 10° to allow proper water drainage.\n\nThe flutes must always run vertically, from the top of the slope down to the bottom. Installing them sideways prevents proper drainage and may compromise the sheet’s structural integrity. Also, sheets cannot be joined vertically from top to bottom.\n\nFor a watertight seal, use low modulus neutral cure sealants and cross-linked butyl flashing tape only, as recommended by the manufacturer.\n\n\u003ch3\u003eCutting and Shaping\u003c\/h3\u003e\nThe Corotherm 25mm 7Xwall sheet is easy to work with and won’t crack or splinter during cutting when handled correctly. If you're cutting along the flutes, a sharp utility knife is ideal. For cross cuts, use a fine-toothed saw. To shape the sheet into curves, a fine-toothed jigsaw will give you clean, smooth results.\n\n\u003ch3\u003eThermal Expansion\u003c\/h3\u003e\nLike all polycarbonate products, these sheets expand and contract with temperature changes. Always allow for thermal movement during installation by leaving a small gap at the top of each sheet and drilling holes 3mm larger than the fixings.\n\nAvoid over-clamping or tightening, as this restricts expansion and could lead to cracking or buckling over time.\n\n\u003ch3\u003eCleaning and Maintenance\u003c\/h3\u003e\nKeeping your sheet clean is straightforward. Just wash with lukewarm soapy water and a soft sponge or cloth. Avoid abrasive tools, hard brushes, or strong alkaline cleaners, which can scratch or damage the surface.\n\nThanks to the UV-protected coating and smooth finish, the sheet naturally repels dirt and debris, making maintenance low-effort.\n\n\u003ch3\u003e10-Year Warranty\u003c\/h3\u003e\nEach Corotherm 25mm 7Xwall sheet comes with a 10-year warranty against manufacturing defects under normal weather conditions. If an issue arises due to a factory fault within this period, a free replacement will be provided.\n\nHowever, the warranty is only valid if the sheet is installed and maintained correctly, following all manufacturer instructions. It does not cover reinstallation costs or secondary damage.\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003ch4\u003e1. What makes the 25mm 7Xwall better for insulation?\u003c\/h4\u003e The 7-wall structure of this sheet traps air between multiple layers, which significantly reduces heat transfer. With a **U-value of 1.4W\/m²K**, it offers better thermal performance than thinner alternatives—making it ideal for conservatories and enclosed roofs where insulation is key. \u003ch4\u003e2. Can I install this sheet on a flat roof?\u003c\/h4\u003e No, flat installation isn’t advised. The roof must have a **minimum 10° pitch** to allow water to drain away properly. Installing the sheet flat can cause water pooling, which shortens the lifespan and may void the warranty. \u003ch4\u003e3. What’s the difference between heatguard opal and regular opal?\u003c\/h4\u003e While both offer light diffusion, **heatguard opal** is a dual-tinted option designed to **reflect more solar heat**. It helps keep interior spaces cooler, making it a better choice for sun-exposed areas like **greenhouses, sunrooms, or south-facing roofs**.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/roofing-supplies\"\u003eroofing supplies\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eBrowse more \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/polycarbonate-roof-sheets\"\u003ecorotherm roof sheets\u003c\/a\u003e available online.\u003c\/p\u003e","brand":"Ariel Plastics","offers":[{"title":"Clear \/ 2000mm x 1050mm","offer_id":50804925792598,"sku":"118633","price":65.98,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2000mm x 1600mm","offer_id":50804925825366,"sku":"118638","price":100.56,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2000mm x 2100mm","offer_id":50804925858134,"sku":"118643","price":131.96,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2000mm x 700mm","offer_id":50804925890902,"sku":"118618","price":43.99,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2000mm x 800mm","offer_id":50804925923670,"sku":"118623","price":50.28,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2000mm x 900mm","offer_id":50804925956438,"sku":"118628","price":56.56,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2500mm x 1050mm","offer_id":50804925989206,"sku":"118634","price":82.47,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2500mm x 1600mm","offer_id":50804926021974,"sku":"118639","price":125.67,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2500mm x 2100mm","offer_id":50804926054742,"sku":"118644","price":164.96,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2500mm x 700mm","offer_id":50804926087510,"sku":"118619","price":54.99,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2500mm x 800mm","offer_id":50804926120278,"sku":"118624","price":62.84,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 2500mm x 900mm","offer_id":50804926153046,"sku":"118629","price":70.69,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 3000mm x 1050mm","offer_id":50804926185814,"sku":"118635","price":98.99,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 3000mm x 1600mm","offer_id":50804926218582,"sku":"118640","price":150.82,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 3000mm x 2100mm","offer_id":50804926251350,"sku":"118645","price":197.96,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 3000mm x 700mm","offer_id":50804926284118,"sku":"118620","price":65.98,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 3000mm x 800mm","offer_id":50804926316886,"sku":"118625","price":75.41,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 3000mm x 900mm","offer_id":50804926349654,"sku":"118630","price":84.82,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 4000mm x 1050mm","offer_id":50804926382422,"sku":"118636","price":131.96,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 4000mm x 1600mm","offer_id":50804926415190,"sku":"118641","price":201.1,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 4000mm x 2100mm","offer_id":50804926447958,"sku":"118646","price":263.94,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 4000mm x 700mm","offer_id":50804926480726,"sku":"118621","price":87.99,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 4000mm x 800mm","offer_id":50804926513494,"sku":"118626","price":100.56,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 4000mm x 900mm","offer_id":50804926546262,"sku":"118631","price":113.11,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 6000mm x 1050mm","offer_id":50804926579030,"sku":"118637","price":197.96,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 6000mm x 1600mm","offer_id":50804926611798,"sku":"118642","price":301.66,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 6000mm x 2100mm","offer_id":50804926644566,"sku":"118647","price":395.91,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 6000mm x 700mm","offer_id":50804926677334,"sku":"118622","price":131.96,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 6000mm x 800mm","offer_id":50804926710102,"sku":"118627","price":150.82,"currency_code":"GBP","in_stock":true},{"title":"Clear \/ 6000mm x 900mm","offer_id":50804926742870,"sku":"118632","price":169.68,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/4509\/4998\/files\/corotherm-clear-25mm-7xwall-polycarbonate-roofing-sheet-ariel-plastics-8434089.jpg?v=1772662167"},{"product_id":"corotherm-opal-25mm-7xwall-polycarbonate-roofing-sheet-ariel-plastics","title":"Corotherm Opal 25mm 7Xwall Polycarbonate Roofing Sheet -

Whether you’re covering a conservatory, carport, canopy, or lean-to roof, this sheet combines style, comfort, and practicality in one long-lasting solution.\n\nYou can purchase it in full sheets or request it cut to size, and it’s all backed by a reassuring 10-year manufacturer’s warranty.\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\nAvailable in clear, bronze, opal, bronze opal, and heatguard opal finishes\n\nLightweight yet highly impact-resistant\n\nUV-protected for durability and colour retention\n\nExcellent insulation performance (U-value: 1.4W\/m²K)\n\nHelps reduce condensation build-up\n\nLow maintenance thanks to its self-cleaning surface\n\nCovered by a 10-year manufacturer’s warranty\n\n\u003ch3\u003eIdeal For\u003c\/h3\u003e\nThe Corotherm 25mm 7Xwall sheet is a great fit for various domestic and commercial projects, including:\n\nPorches\n\nCarports\n\nCanopies\n\nConservatories\n\nLean-to roofs\n\nVertical glazing and cladding\n\nThe heat-reflective qualities of the heatguard opal finish make it particularly suitable for sunrooms, greenhouses, or south-facing roofs where excess heat build-up is a concern.\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\nTo get the best performance from your Corotherm sheet, it’s essential to install it correctly. Always make sure the UV-protected side, clearly marked by the manufacturer, is facing outward. This protects the sheet from sun degradation and helps maintain clarity over time.\n\nThe roof should be pitched at a minimum angle of 10° to allow water to drain properly. The flutes must run vertically—from the top of the slope down to the bottom. Never lay the sheets flat or with the flutes running horizontally, and note that vertical joining (top-to-bottom) is not permitted.\n\nFor sealing and weatherproofing, only use low modulus neutral cure sealants and cross-linked butyl flashing tape.\n\n\u003ch3\u003eCutting and Shaping\u003c\/h3\u003e\nThese sheets are easy to cut without the risk of cracking or shattering. For straight cuts along the flutes, a sharp utility knife is ideal. If you're making cross cuts, use a fine-toothed saw. For curves or shaped cuts, a fine-toothed jigsaw works best.\n\nAlways ensure the sheet is properly supported while cutting to avoid flex or slippage.\n\n\u003ch3\u003eThermal Expansion\u003c\/h3\u003e\nPolycarbonate expands and contracts slightly with temperature changes. To accommodate this, always leave a gap at the top of the sheet during installation, and when drilling, ensure there’s at least 3mm clearance around each fixing to allow for movement.\n\nAvoid overtightening screws or clamping the sheet too tightly—this can restrict expansion and may lead to warping or stress fractures over time.\n\n\u003ch3\u003eCleaning and Maintenance\u003c\/h3\u003e\nKeeping your sheet looking its best is simple. Use lukewarm water with mild soap and wipe it clean using a soft cloth or sponge. Avoid anything abrasive—no scouring pads, wire brushes, or harsh alkaline cleaners—as these can damage the UV-protective layer and dull the finish.\n\nThanks to its smooth surface and UV-resistant coating, the sheet resists dirt build-up and is largely self-cleaning, reducing the need for frequent maintenance.\n\n\u003ch3\u003e10-Year Warranty\u003c\/h3\u003e\nThe Corotherm Heatguard Opal 25mm 7Xwall sheet comes with a 10-year warranty that covers any faults due to manufacturing defects under normal use and weather conditions.\n\nPlease note that for the warranty to be valid, the sheet must be installed and maintained according to the manufacturer’s guidelines. The warranty does not cover damage from incorrect installation or reinstallation costs.\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003ch4\u003e1. What’s the benefit of the heatguard opal finish over regular opal?\u003c\/h4\u003e The heatguard opal finish is designed to **reflect more solar heat** than the standard opal option, helping to reduce interior temperatures. It still allows natural light to filter through but keeps spaces cooler—making it perfect for sunrooms or areas that receive intense sunlight. \u003ch4\u003e2. Can I use this sheet for a flat roof?\u003c\/h4\u003e No, this product should **not be installed on a flat roof**. The roof must have at least a **10° pitch** to ensure proper water drainage. Installing it flat could lead to pooling water and reduce the sheet’s lifespan. \u003ch4\u003e3. Is the sheet easy to work with for DIY projects?\u003c\/h4\u003e Yes! The sheet is **lightweight and simple to cut** using basic tools like a utility knife, fine-toothed saw, or jigsaw, depending on the cut required. Just be sure to support the sheet while cutting and follow proper installation practices to get the best results.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/roofing-supplies\"\u003eroofing supplies\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eBrowse more \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/polycarbonate-roof-sheets\"\u003ecorotherm roof sheets\u003c\/a\u003e available online.\u003c\/p\u003e","brand":"Ariel Plastics","offers":[{"title":"Heatguard Opal \/ 2000mm x 1050mm","offer_id":50805037728086,"sku":"118728","price":75.89,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 2000mm x 2100mm","offer_id":50805037760854,"sku":"118733","price":151.77,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 2000mm x 700mm","offer_id":50805037793622,"sku":"118723","price":50.61,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 2500mm x 1050mm","offer_id":50805037826390,"sku":"118729","price":94.86,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 2500mm x 2100mm","offer_id":50805037859158,"sku":"118734","price":189.71,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 2500mm x 700mm","offer_id":50805037891926,"sku":"118724","price":63.24,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 3000mm x 1050mm","offer_id":50805037924694,"sku":"118730","price":113.81,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 3000mm x 2100mm","offer_id":50805037957462,"sku":"118735","price":227.65,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 3000mm x 700mm","offer_id":50805037990230,"sku":"118725","price":75.89,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 4000mm x 1050mm","offer_id":50805038022998,"sku":"118731","price":151.77,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 4000mm x 2100mm","offer_id":50805038055766,"sku":"118736","price":303.53,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 4000mm x 700mm","offer_id":50805038088534,"sku":"118726","price":101.18,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 6000mm x 1050mm","offer_id":50805038121302,"sku":"119004","price":227.65,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 6000mm x 2100mm","offer_id":50805038154070,"sku":"118737","price":455.3,"currency_code":"GBP","in_stock":true},{"title":"Heatguard Opal \/ 6000mm x 700mm","offer_id":50805038186838,"sku":"118727","price":151.77,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/4509\/4998\/files\/corotherm-heatguard-opal-25mm-7xwall-polycarbonate-roofing-sheet-ariel-plastics-8548970.jpg?v=1772662160"}],"url":"https:\/\/jjbuildingmaterials.co.uk\/collections\/polycarbonate-roof-sheets.oembed","provider":"JJ Building Materials","version":"1.0","type":"link"}
