Closed Panel System
Our prefabricated timber frame panels, manufactured at our factory in Sussex, achieve exceptionally low U-values.
We supply a high performance closed panel timber frame system, a prefabricated product that will save both time and energy on projects. Our closed panel system is pre-constructed, complete with insulation and vapour control built-in, ensuring installation times are fast. Closed panel timber frame building systems are efficient, both in terms of construction speed and energy conservation; the factory-installed airtight membrane helps to reduce air leakage and heat loss in the finished structure.
