This quality framework includes all the important quality requirements for post-insulation of cavity walls with a nominal width of at least 50 mm.
Good post-insulation of uninsulated cavity walls can reduce energy loss by a factor of 2 to 3, depending on the structure of the original façade and the thermal resistance of the insulation product used. This improves the energy performance and the living comfort.
UBAtc (Belgian Union for Technical Approval in the construction sector) and BCCA combined three kinds of requirements in this quality framework to contribute to the quality improvement of post-insulation of cavity walls:
Companies participating in the quality framework can issue conformity declarations for cavity walls insulation. The declaration confirms the use of insulation systems that have a Technical Approval, the use of qualified personnel, and the conformity of the executed insulation works with the requirements Technical Specification STS 71-1.
Installer companies that use products with ATG approval and that enter into an agreement with BCCA to comply with the regulations of the post-insulation of cavity walls quality framework.
