Cavity Closers
Cavity closers are essential components in construction, designed to seal the cavities around window and door openings to prevent water ingress and minimise the risk of a fire spreading. Additionally, cavity closers improve the structural integrity of window and door cavities, providing a clean, secure edge finish while improving the thermal efficiency of your home. For applications in tight or limited spaces, we stock single-flange closers, and for larger cavities, we stock double-flange cavity closers. We also have a range of fire-rated closers for enhanced fire protection within your home or building.
By minimizing thermal bridging, they help maintain consistent internal temperatures and improve overall energy efficiency. Their effective use creates 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.
