Rytons A1® Fire-rated Ducting Kits 110mm x 54mm with Single Air Bricks

General Details

Features and Benefits:

  • A range of tailor-made metal ducting kits compatible with rectangular HVAC supply and extract ducting 110mm x 54mm.
  • Made from Class A1 fire-rated galvanised steel and compliant with regulations for the requirement of non-combustible ducting in the external walls of high-rise buildings over 18m (11m in Scotland) and those 11m and above undergoing unsafe cladding remediation work.
  • Straight kit, 90° balcony kit and s-shape window head kit designs provide options to accommodate a variety of ductwork locations.
  • Three air brick grille styles satisfy the varying design, airflow, and vent placement requirements of buildings.  For cladding, flanged options cover cut edges to maintain the external appearance.
  • Air bricks maintain low resistance and have high airflows of over 90% of the free area of the duct.
  • Custom powder coated air brick.  Choose from the RAL Classic colour chart in matt, semi-gloss or gloss finish (achieving Class A2-s1, d0) for an air brick that matches cladding or brickwork.  Signature architectural coatings 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.
  • Air brick/plenum are brick size (rather than duct size) for easy installation using standard mortar joints for a neat appearance in brickwork.
  • Telescopic fitting air brick allows the overall length of the kit to be extended during installation giving the flexibility to handle minor variations in the external façade.

  • Supplied ready to install with no on-site assembly required.
  • Duct factory fitted to the plenum adaptor.
  • No screw fixing or sealing required, saving time, labour and ensuring correct alignment and airtight joints throughout.
