It is a type HR underlay and roof space ventilation is required at both high and low level.\u003cbr\u003eEnvirolay is B.R.E. and Exova certified and is great for both warm and cold roof, supported and unsupported, ventilated roof constructions throughout the UK. The flame retardant woven glass fibre cloth and aluminium foil weave has a high nail tear resistance which makes it anti-tear in normal use. The thermal reflectivity of the material is made to reduce the convection and radiant heat loss through the roof. In the summer months it reduces heat entering into the building, but also helps to maintain the heat in the building during the winter.\u003c\/p\u003e","brand":"Plastic Centre Online","offers":[{"title":"Default Title","offer_id":54024750989653,"sku":"ENVIROLAY","price":289.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/5775\/7781\/files\/ab4d5442ce909df772e4bce7ca2095a9_2_f2e20ec3-20bc-44d3-b9b2-a92c44bff308.jpg?v=1780062279","url":"https:\/\/plasticcentreonline.co.uk\/products\/envirotile-roof-underlay-membrane-length-25m-x-width-1-3m","provider":"Plastic Centre Online","version":"1.0","type":"link"}
