Cavity Closers
Cavity closers are essential components in construction, designed to seal the cavities around window and door openings. From preventing water ingress to stopping the spread of fire, they enhance thermal efficiency by reducing heat loss and resist moisture, thereby protecting against dampness and mold. Additionally, cavity closers improve the structural integrity of window and door cavities, providing a clean, secure edge finish and acting as a barrier against pests. For applications in tight or limited spaces, we stock single-flange cavity closers. For larger cavities, we stock double-flange cavity closers, as well as fire rated closers for enhanced fire protection.
By minimizing thermal bridging, they help maintain consistent internal temperatures and improve overall energy efficiency. Their effective use contributes to creating more durable, moisture-resistant structures that comply with contemporary building regulations. We supply reliable brands such as Timloc, Manthorpe, and ARC Building Solutions, so you have plenty of options to choose from.
If you’re seeking to prevent heat loss, opt for thermal or insulated cavity closers. They will help prevent the build-up of condensation, mould and damp, while a fire-rated cavity closer will slow the spread of fire and allow your property to comply with Building Regulation Part B.
