Cavity Closers
About Our Cavity Closers
We have cavity closers that give window and door openings around cavity walls a neat and insulated finish.
Manufactured from rigid EPS insulation, our stock prevents cold bridging, improves airtightness, and enhances a building’s overall thermal performance.
This range includes versatile cavity closers 100mm and above, suitable for both new builds and retrofit installations.
Our cavity closers are sourced from leading manufacturers, ensuring reliable insulation, easy installation, and long term performance.
Cavity Closers for Reliable Insulation and Moisture Protection
Cavity closers form an essential part of modern wall construction, sealing the gap between inner and outer leaves while preventing moisture ingress and heat loss.
By combining insulation and damp proof protection within one product, they make the installation process more simple, while also ensuring long term performance.
Each unit incorporates a rigid PVC profile and expanded polystyrene (EPS) insulation core, creating a robust, lightweight component that’s easy to cut and fit on site. This design provides a continuous barrier against cold bridging and helps you to comply with current building regulations for energy efficiency.
Available in several sizes to suit standard wall cavities, such as 100mm cavity closers and larger formats, our closers can be used vertically around window and door frames or horizontally at sill and lintel junctions.
Their clean, precise edges deliver a professional finish that supports both thermal performance and aesthetic quality.
