Description
Features & Benefits:
- 150mm high back upstand exceeds minimum requirements
- Permanent stopend protects the perpendicular joint and cuts out water backtracking along the blockwork/stonework
- Angled section between cavity tray base and rear upstand automatically sheds water to the outer leaf Cavity tray builds into the outer leaf only to speed up installation and allow both inner and outer leafs to be built independently if required
- Choice of two lengths: 625mm for roof pitches of 25 degrees or above; 1250mm for roof pitches of 12.5-22.5 degrees
- The system is available on request with pre-applied polystyrene strips
- Polystyrene is much easier to rake out than mortar and offers a visual locator of the cavity tray so aiding the installation of post fitted lead work (this service may incur additional charge)
Where to use:
- At the abutment of a pitched roof with a cavity wall
- On external walls – not exceeding 150mm thickness – built from blockwork or stone with regular course heights, including mortar of approx. 225mm
- On roof pitches of 12.5 degrees and above
- Clear cavity widths of between 50mm-125mm
