Closed Panel Timber Frames | Homes by Western

We offer closed wall panels in our timber frame kits, providing clients with prefabricated panels featuring integrated insulation and sheathing for efficient construction.

In timber frame construction for homes, closed panel walls are an alternative to open panel walls. Closed panel systems involve the prefabrication of entire wall panels in our controlled factory environment, including the installation of insulation and other components. These panels, complete with sheathing, insulation, and sometimes windows, are then transported to the construction site and assembled into the frame.

- enhanced performance

Closed panel walls offer advantages such as increased speed of construction, higher precision due to factory manufacturing, and improved energy efficiency. They are particularly popular for residential buildings where rapid assembly and enhanced thermal performance are desirable. The closed panel approach streamlines the construction process, contributing to overall efficiency and quality in timber frame home construction.
