Exceptional thermal insulation and sustainability credentials
Walker Timber Group’s closed-panel building system offers exceptional thermal insulation and sustainability credentials in one package. Manufactured using state-of-the-art equipment, this system has insulation injected directly into the timber panels, which allows for closed management of all costs. This method reduces waste and improves a building’s thermal performance and air tightness, as well as simplifying the construction process.
The system comprises roof, wall and floor panels, which can be combined to create a whole building envelope, or as infill panels for other building systems. The panels contain a precisely engineered sandwich of sheathing boards, performance membranes and factory-injected, high performance insulation, which is derived from recycled, renewable vegetable oil.
The insulation is injected into the panel under strict quality control and expands to fill every square millimetre of space in the panel – making it a super-efficient building fabric. This offers a cost-effective way to deliver a load-bearing structural envelope, with thermal insulation wall U-values in the range of 0.09 W/m2K to 0.23 W/m2K, with negligible thermal bridging and excellent air tightness.
