Features and Benefits:
Rytons A1® Fire-rated AirLiner® Cross-cavity Sleeves
General Details
- Custom-made cross-cavity AirLiner® sleeves in sizes 9×3, 9×6 and 9×9.
- Popular brick sizes for easy installation using standard mortar joints.
- Manufactured from A1 classified galvanised steel.
- If required, three air brick styles meet different design, airflow and vent placement requirements in buildings. For cladding, flanged options cover cut edges to maintain the external appearance.
- Air bricks provide high air flows whilst maintaining low resistance.
- Air bricks supplied custom powder coated to Class A2-s1, d0. Choose from the RAL Classic colour chart in matt, semi-gloss or gloss finishes to match cladding or brickwork. Signature architectural finishes are also available.
- Built-in weather protection. Drainage holes in the air brick provide discreet water outlets, and louvred styles feature angled grilles to promote runoff, reducing the risk of water transfer into the duct.
- Suitable for:
- The external walls of high-rise relevant buildings over 18m high (11m high in Scotland).
- The external walls of relevant buildings 11m+ in height or more than 5 storeys, undergoing unsafe cladding remediation work (Building Safety Act 2022).

- The external surfaces of residential purpose group buildings more than 11m high.
- The external surfaces of residential purpose group buildings 11m high or less where an external wall is within 1m of the relevant boundary.
