Timber Frame construction represents a structural building method employing substantial timber elements to support the framework. In timber frame buildings, the external structural wall incorporates timber studs designed to bear loads and transfer them to the foundation system. The walls, floors, and roofs function as an integrated, engineered structural assembly.
The 80mm Unilin Thin-R XT/TF system delivers superior thermal performance for wall insulation in timber framed walls, exceeding baseline building regulation requirements. This 80mm XT/TF board enables achievement of Future Home and Passive House Standards when specified for timber frame construction.
