XT/Walk-R

Thin-R Loft Decking XT/Walk-R is a composite of high performance PIR insulation with tough OSB board that provides safe access into insulated roof spaces. XT/Walk-R maintains very high insulation values and complies with health and safety guidelines.

Whether building new or upgrading, due consideration towards the energy efficiency of your home can have many benefits, including reduced energy costs and improved living conditions. One of the easiest and most cost effective measures to take is to insulate the roof space. But how do you allow safe access to this space, water tanks, services and fittings? XT/Walk-R is the solution and provides safe entry as well as improved insulation of the attic space.
