• At the abutment of a flat roof with a cavity wall;
• At the abutment of a lean-to or mono pitch roof with a cavity wall;
• Over airbricks, cavity liners, ducts, meter boxes, etc.;
• Clear cavity widths of 50–150 mm.
• New build only: Over concrete ring beams;
• Refurbishment only: For remedial work where a horizontal cavity tray must be inserted into an existing wall.
• Refurbishment only: On external walls (not exceeding 102.5 mm-thick) built from standard brickwork, blockwork or stone.

Horizontal cavity tray system for all types of brick, block and stone new build constructions or remedial work on existing walls.

Features and benefits:

• Can be specified separately with a pre-applied polystyrene strip mortar barrier.

New build:

• 150 mm-high back upstand exceeds minimum requirements.
• Low profile lapped joint between sections allows any length of brick, block or stone to be used without difficulty.
• 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 to allow both inner and outer leafs to be built independently if required.
• Choice of two lengths: 880 mm for general use; 460 mm to reduce waste when making up a run of cavity tray to the required length.

Refurbishment:

• Compact size and design allows insertion into an existing wall without ever having to remove more than three bricks at any one time.
• Low profile lapped joint between sections allows for variations in brick size.
• Angled section between cavity tray base and rear upstand automatically sheds water to the outer leaf.
• Cavity tray builds into the outer leaf only, so there is no need to disturb the inner wall of the building.

Quality:

• Satisfies all NHBC requirements.
• Manufactured to BS EN ISO 9001 and BS EN ISO 14001.
• Complies with all relevant Building Regulations.
• Meets all relevant British Standards.
