Installed on the warm side of the insulation, it combines exceptional vapour resistance with a reflective surface that helps retain heat within the building.\u003c\/p\u003e\n\u003cp\u003eThe thermo-reflective surface helps reflect radiant heat back into the building, supporting improved energy efficiency when incorporated into an appropriately designed construction. Its impermeable construction also creates an effective air barrier, helping increase airtightness and restrict moisture-laden air from reaching the insulation.\u003c\/p\u003e\n\u003cp\u003eWith a water vapour resistance of greater than 25,000 MNs\/g, UltraBlock 300 is particularly suited to high-humidity environments, including industrial kitchens and leisure centres, where robust vapour control is especially important. By limiting the passage of water vapour, the membrane helps protect insulation and reduce the risk of interstitial condensation within the building fabric.\u003c\/p\u003e\n\u003cp\u003eAn integrated reinforcement scrim provides additional strength for installation across walls and ceilings, making UltraBlock 300 a durable solution for demanding building envelope applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThermo-reflective air and vapour control layer for roof, wall and ceiling applications\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eReflective surface helps retain radiant heat and support improved energy efficiency\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eParticularly suited to high-humidity environments such as industrial kitchens and leisure centres\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eExceptional \u0026gt;25,000 MNs\/g water vapour resistance\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHelps protect insulation against the risk of interstitial condensation\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eImpermeable air barrier helps improve building airtightness\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInstalled on the warm side of insulation\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eReinforcement scrim provides additional strength and durability\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSuitable for a wide range of roof and wall constructions\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCE marked\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ITP Ltd","offers":[{"title":"Default Title","offer_id":53813464891739,"sku":"VANS 2050H","price":312.31,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0793\/7019\/1195\/files\/powerlon-ultrablock-300-thermo-reflective-air-vapour-control-layer-2m-x-50m-1741876.jpg?v=1787747409","url":"https:\/\/trustedbuildingsupplies.co.uk\/products\/powerlon-ultrablock-300-thermo-reflective-air-vapour-control-layer-2m-x-50m","provider":"Trusted Building Supplies","version":"1.0","type":"link"}
