Timber Frame construction represents a structural building method employing substantial timber members to support the framework. Within timber frame buildings, the external structural wall assembly incorporates timber studs designed to manage loads and transfer them through to the foundation system. The integrated design of floors, roofs, and walls functions as a unified, engineered structural system.
The 100mm Unilin Thin-R XT/TF system delivers superior thermal performance for timber frame wall insulation applications, exceeding the baseline requirements specified in contemporary building regulations. Installing 100mm XT/TF boards within timber framed walls facilitates compliance with Future Home and Passive House Standards.
