- Prevents cold bridging
- Acts as a bricklaying template enabling thermally efficient fitting of windows and doors
- Rigid PVCu profile
- Compatible with all window and door materials
- BBA approved profile and Part L 2010 compliant
Fitting Instructions
- When brickwork is at sill level place former into the cavity and brace former squarely
- Brick up jambs, using ties at 300mm centres
- Continue around head detail and remove timber bracing, fit window
ARC Insulated DPC
