SupaWall Blow-In External Wall is a solution designed for retrofitting exterior walls with Supafil Frame insulation.
The solution includes a Building Assessment, Masonry Protection Barrier installation for masonry walls, Supafil Frame insulation installation and a Post-Installation Audit.
Supafil Frame insulation is a water-repellent, loose-fill, fibrous glasswool thermal insulation product. Supafil Frame insulation is identified by branded bags with labels containing detailed product and batch information. The Masonry Protection Barrier is used to reduce water penetration through masonry veneer walls, and is specified by Enstall Insulation Ltd.
The SupaWall Blow-In External Wall solution is for retrofitting to existing buildings with:
- Timber-framed walls with direct fixed cladding which must have wall underlay; or,
- Timber-framed walls with masonry veneer cladding, with or without wall underlay.
The SupaWall Blow-In External Wall solution must install Supafil Frame insulation through the internal wall lining.
The building must be deemed suitable for the SupaWall Blow-In External Wall solution by an Enstall Insulation Ltd trained and approved assessor, prior to installation by an Enstall Insulation Ltd trained and approved installer.
Buildings with masonry veneer claddings must have the Enstall Insulation Ltd specified Masonry Protection Barrier applied prior to the installation of Supafil Frame insulation by an Enstall Insulation Ltd trained and approved installer.
