Timber Frame construction represents a structural approach that employs substantial timber members to support building frameworks. 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 125mm Unilin Thin-R XT/TF system delivers exceptional thermal performance for wall insulation in timber framed walls, exceeding standard building regulation requirements. This 125mm thickness enables compliance with Future Home and Passive House Standards.
