What are cavity closers and how do you install them? Product Guide: Insulation See all. What is a cavity closer? Insulated cavity closers Insulated cavity closers have the same features as most cavity closers, meaning there is a damp proof membrane to help prevent the ingress of moisture which causes damp and condensation issues , as well as PVC extrusions and a flexible seal.
Which brands offer cavity closers? Why do you need a cavity closer? Cavity closers have three main priorities when installed around a door frame or window frame within a cavity wall: To prevent water ingress To reduce heat loss To improve fire safety Prevent water ingress Firstly, a cavity closer will prevent the ingress of water occurring around the edges of a window or door, acting as a damp proof course, reducing the potential for damp, condensation and mould from occurring.
Reduce heat loss Secondly, cold bridging commonly occurs around windows and doors, where heat transfer is much greater, significantly reducing thermal insulation. Improve fire safety Thirdly, a cavity closer will help to improve the fire safety of the building, particularly when the cavity closer is specifically a fire-rated cavity closer — fire rated cavity closers can prevent the spread of fire for 30 minutes or an hour, depending on the fire-rated product you choose.
