Timber frame wall insulation for timber frame is an essential component in creating a comfortable and energy efficient home. However, there are a number of different methods and materials that can be used. The information in this article is intended to help you understand the options available and to make informed choices. It covers everything from insulation types to breathable membranes.

Timber framed walls consist of structural softwood vertical studs that carry the imposed loads through to the foundations. These are sheathed with wood based panel sheathing and then lined with plasterboard. Thermal insulation is incorporated into the spaces between the studs. Insulation materials vary in terms of their thermal, fire safety, and acoustic performance. Rigid foam insulation boards are the most commonly used in timber framed buildings. They are available in a wide range of thicknesses, and they can be made to meet the exact requirements of any project.

Timber Frame External Wall Insulation: Benefits and Installation

Breather membranes are water-resistant but vapor permeable materials that control moisture movement in timber frame walls and other timber structures. The use of breather membranes is vital in ensuring that the timber reaches its optimal moisture content prior to installing insulation, which can prevent damage and rot.

Timber frame panels can be manufactured off-site in either ‘Open Panel’ or closed system configurations. Closed panels have a convenient service void incorporated into the panel, which makes them an ideal choice for first fix services to complete their works and provide a more rapid construction time.
