Description
The insulated cavity closer 100-150mm x 2.4m grey is a high-performance building component designed to seal cavity wall openings around windows, doors and structural reveals in modern construction. Suitable for cavity widths between 100mm and 150mm, this insulated cavity closer helps prevent cold bridging, moisture ingress and air leakage while providing a neat and compliant finish to cavity wall openings.
Manufactured with a durable uPVC outer profile and an insulated core, this cavity closer delivers reliable thermal performance and long-term durability in both new build and refurbishment projects. It forms a continuous insulated barrier between the inner and outer leaf of the wall, improving energy efficiency and reducing condensation risks around openings.
The 2.4 metre length is ideal for standard window and door installations, allowing for quicker installation with fewer joins and improved on-site efficiency. The insulated cavity closer is lightweight, easy to cut and simple to handle, making it suitable for builders, contractors and installers working across residential, commercial and general construction projects.
Designed to provide a stable fixing surface for window and door frames, trims and internal finishes, this cavity closer also supports compliance with current building regulations relating to thermal performance and moisture control. Its robust construction ensures consistent performance in demanding site environments while maintaining a clean and professional reveal finish.
Commonly used in window reveals, door openings, extensions and new build cavity wall systems, this insulated cavity closer is an essential solution for achieving airtight, energy-efficient and weather-resistant building envelopes.
