Can Warmline PIR insulated plasterboard be used in a bathroom?\u003c\/h4\u003e Yes, it can be used in bathrooms, but in areas with direct water contact (such as shower enclosures), it's better to use moisture-resistant plasterboard or tile backer board. For humid but dry-walled areas, ensure adequate ventilation and use appropriate finishes. \u003ch4\u003e2. How do I fix these boards to the wall?\u003c\/h4\u003e You can use mechanical fixings, adhesive dot-and-dab method, or a combination of both depending on the surface. Dot-and-dab is common for solid masonry walls, while mechanical fixings are often used on timber or metal studs. \u003ch4\u003e3. What thickness should I choose for my project?\u003c\/h4\u003e It depends on your insulation target and wall depth. **37.5mm or 52.5mm** are ideal for minimal build-up in refurbishment projects, while **62.5mm or 72.5mm** are better suited for colder walls or when higher thermal performance is needed.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/insulation\"\u003einsulation\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eBrowse more \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/insulation-board\"\u003einsulation board\u003c\/a\u003e available online.\u003c\/p\u003e","brand":"U Value","offers":[{"title":"37.5mm","offer_id":51553820279126,"sku":"152003","price":48.81,"currency_code":"GBP","in_stock":true},{"title":"52.5mm","offer_id":51553820311894,"sku":"152004","price":54.63,"currency_code":"GBP","in_stock":true},{"title":"62.5mm","offer_id":51553820344662,"sku":"152005","price":64.06,"currency_code":"GBP","in_stock":true},{"title":"72.5mm","offer_id":51553820377430,"sku":"152006","price":71.86,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/4509\/4998\/files\/u-value-warmline-pir-paper-insulated-plasterboard-8755546.jpg?v=1772656580","url":"https:\/\/jjbuildingmaterials.co.uk\/products\/u-value-warmline-pir-paper-insulated-plasterboard","provider":"JJ Building Materials","version":"1.0","type":"link"}
