Domus Ventilation, part of the Polypipe group, has launched the new Solis Air Brick range of low resistance, non-combustible metal air bricks that are fully compliant with the revised Building Regulations Fire Safety Approved Document B.
Changes to the Building Regulations, which came into force in November 2020, requires “ductwork penetrating through the external cavity including termination to be non-combustible” when above 18m in England and 11m in Scotland, although it is expected the more stringent 11m rule will eventually be applied throughout the UK. The new Solis Air Brick is made from 1.5mm galvanized steel (fire class A1) non-combustible material to meet these changes to the regulations and ensure compliance.
The Domus Ventilation Solis Air Brick comes in three options: 204x60 single metal air brick, and 220x90 and 220x126 double metal air bricks. They are suitable for use with all external wall types and come with a wide range of architectural grilles in a choice of colours for internal and external use. They are fully compatible with Domus rigid ducting ranges and Domus Thermal duct insulation.
The Solis Air Brick is the latest addition to Domus Ventilation’s Building Regulations compliant ducting fire protection products. The company has a range of Fire Sleeves and Fire Collars which prevent the spread of fire where ventilation ducting penetrates fire compartment walls. To achieve this, Domus Fire Collars and Sleeves are made using a flexible galvanised steel shell containing graphite based intumescent material to ensure "impressive" fire ratings and have been tested to BSEN 1366-3: 2009.
