Our cavity closers are manufactured in-house at our recycling plant in Wrexham 🏴 and crafted from the highest quality materials.
👉🏼 We offer both Expanded (EPS) Polystyrene and Extruded (XPS) Polystyrene cavity closers in two different profiles (50–100 mm and 100–150 mm) to suit a range of cavity widths.
📏 The smart multi-width design with cut-to-size grooves means our cavity closers are easy to adjust on-site, ensuring a precise fit and reducing installation time. Engineered for excellent thermal performance and long-term durability, they provide an effective barrier against heat loss and moisture ingress, making them the ideal choice for modern, energy-efficient construction. 🔥
