Ducting to Airbrick Adaptor Sets

Simple to install pre-assembled sets, that quickly and conveniently adapts rigid round and rectangular extraction ductwork to terminate at a standard plastic airbrick.

The adaptor sets provides a complete solution when ducting through to an exterior wall. It comes as a single unit in a convenient preassembled set that is built-in as part of the brickwork package and enables first-fix ceiling duct extraction connections.

It terminates at a standard plastic airbrick, which is supplied with the set, and installed exactly the same way as standard airbrick practice, making the process quick and easy.

The Ducting to Airbrick Adaptor Sets are ready to fit straight from the box - saving time, reduces cost and minimises the need for external fitters, core drilling and specialist tools.

Installation advice

  • Build in the set’s airbrick (to replace a regular brick) as normal as brick and blockwork proceeds
  • The installed position and level of the set is determined by the extraction fan connections
  • The set will project beyond the inner wall leaf to allow for the fitting of additional ducting or an extraction fan
  • As with all through cavity wall components install a DPC cavity tray, with wall weep and stopends, above the installed adaptor set to collect any water ingress
  • We recommend the Inter-loc 4 horizontal cavity tray and 1143 or TW1 wall weeps
