100mm Cavity Closers
100mm cavity closers are a specialised building product for effective sealing around doors and windows in buildings with a 100mm cavity. They are made from high-density foam, easy to install and provide excellent thermal insulation. With a width of 100mm, cavity closers are inserted into the gap between the inner and outer walls of the building. This ensures a tight seal around windows and doors, helping prevent heat loss and improving energy efficiency by reducing cold air entering the building.
Alongside thermal insulation properties, these 100mm cavity closers are important to any building's fire system as they help prevent the spread of fire and smoke by creating a barrier around doors and windows. They are also available in various lengths to suit different spaces, with minimal requirements for cutting and trimming. So, whether you're using 100mm cavity closers in new construction or retrofitted to existing buildings, speak to our excellent customer service team for advice and a no-obligation free quote to find the right size for your project. Followed by our UK fast delivery to ensure you can finish your project promptly.
