Timber Frame
Timber frame construction is a building method using prefabricated panels of timber studs, floor joists, and roof trusses to create a structural frame that is faster and more eco-friendly than traditional methods. The frame carries the building's loads and is then clad with materials like brick, wood, or render for weather protection and decoration. This system is known for its efficiency, high-quality control due to off-site manufacturing, and sustainability as timber is a renewable resource.
In England & Wales, the required U-value for external walls in new homes is to be at least 0.18 W/m²K. This value has been updated in recent regulations to reflect stricter energy efficiency standards.
We can supply various wall options to achieve the wall U-Value specified for your project. Please advise us of your specified U-Value so we can ensure the correct solution is selected when quoting. If you are looking to exceed these wall u-values and aim for Passivhaus Standards we can provide a solution.
A sample of wall solutions are shown below with a brick facade. Please note that if there is a lightweight cladding system (as the external facade) then the 9mm OSB3 sheathing board to the outside of the panel will have to be replaced with a suitable A1/A2 rated board and the U-Value shown below will reduce. We will be able to discuss all solutions with you.

140mm Open Panel - NO Insulation
This panel has NO insulation factory fitted. Insulation, vapour control membrane and any service battens (if needed) are to be fitted on site. Wall u-value will vary depending on insulation used.

0.18w/m²k 140mm Open Panel - 80mm PIR Factory Fitted
This panel has 80mm PIR insulation factory fitted. Vapour control membrane and service battens supplied loose for site fitting - to suit a brick facade.

0.16 w/m²k 140mm Open Panel - 120mm PIR Factory Fitted
This panel has 120mm PIR insulation factory fitted. Vapour control membrane and service battens supplied loose for site fitting - to suit a brick facade.
