The Tubolit 1m Wall Foam Pipe Lagging is a practical solution for anyone aiming to improve energy efficiency and protect domestic plumbing systems. Whether you're working with hot water pipes, cold water supplies, or central heating, this 1-metre foam tube delivers reliable insulation with minimal fuss.\n\nCrafted from silver-grey closed-cell polyethylene, this lagging is dust-free, fibre-free, non-brittle, and non-reactive, making it a safe and mess-free option for both DIYers and professional plumbers. It’s designed for quick installation—no adhesives or tapes required—so you can fit it directly over your pipework in minutes.\n\nOne of its major benefits is energy saving. By reducing heat loss in hot pipes and protecting cold pipes from freezing, this insulation helps to lower energy bills and improve the overall efficiency of your heating system. With a short payback period, it’s a small investment that can make a noticeable difference in long-term energy use.\n\nWhether you're updating older plumbing or fitting a new system, Tubolit pipe lagging is available in a range of sizes to suit standard domestic pipe diameters:\n\nAvailable Sizes:\n\n15mm x 9mm\n\n22mm x 9mm\n\n28mm x 9mm\n\n15mm x 13mm\n\n22mm x 13mm\n\n28mm x 13mm\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003ch4\u003eCan I install this pipe lagging myself?\u003c\/h4\u003e Absolutely! Tubolit foam lagging is very user-friendly. You simply open the pre-slit tube, fit it over the pipe, and you're done—no need for glue, tape, or specialist tools. It's great for both quick fixes and larger insulation jobs. \u003cbr\u003e \u003ch4\u003eWill this help reduce noise from water pipes?\u003c\/h4\u003e Yes, in addition to thermal insulation, foam lagging can help reduce the noise of water moving through pipes—particularly in central heating systems. It dampens vibration and sound, making your home quieter. \u003cbr\u003e \u003ch4\u003eIs this lagging suitable for outdoor use?\u003c\/h4\u003e While Tubolit lagging is designed mainly for indoor applications, it can be used outdoors if it’s covered or housed in a weatherproof enclosure.
