Timber Frame construction employs substantial timber members to establish the building framework. In timber frame structures, the external structural wall incorporates timber studs that transfer loads down to the foundation system. The walls, floors, and roofs function as an integrated, engineered assembly designed for structural coherence.
The 120mm Unilin Thin-R XT/TF system delivers exceptional wall insulation performance for timber framed walls, exceeding standard building regulation requirements. Specifying 120mm XT/TF enables compliance with Future Home and Passive House Standards.
