Within BERTIM project a series of tests were conducted in order to validate a new type envelope made of timber and other secondary materials that made up the envelope of this panelised energy efficient upgrading system. Testing of the prototype in a real infrastructure was key element for measuring and validating the performance of these panels and to making steps ahead on the final configuration of the system.

Certification of BERTIM modules is intended to attest timber structural systems achieving common use in retrofitting buildings described in BERTIM project. This certification is based on a technical description, which respects the actual regulations in Europe. The building retrofitting modules for BERTIM have to be validated considering all of the points in the repository: 2D modules and 2D modules with installations.
