EVA foam cavity closers are specialised building components designed to seal and insulate the gaps in cavity walls, particularly around window and door openings. Made from high-quality EVA foam, these closers provide effective thermal insulation and help prevent cold bridging, moisture ingress, and air leakage, thereby enhancing the energy efficiency and airtightness of the building envelope.
Thanks to the closed-cell structure of EVA foam, these cavity closers are highly resistant to water and vapour penetration, ensuring long-lasting durability and protection against damp. Their flexibility and lightweight nature allow for easy handling and installation, with the ability to conform to irregular shapes and tight spaces.
EVA foam cavity closers are suitable for use in a variety of construction types, including masonry, timber frame, and steel frame buildings. Their excellent resistance to chemicals and UV exposure also makes them ideal for external applications where durability is essential.
EVA foam, or Ethylene Vinyl Acetate foam, is a versatile, closed-cell foam material known for its excellent shock absorption, flexibility, and resistance to moisture, chemicals, and UV rays. It is a durable thermoplastic polymer widely used in various applications including padding in sports equipment, footwear, crafts, and insulation. EVA foam is lightweight, resilient, and resistant to environmental factors, making it suitable for both indoor and outdoor use.
