Kingspan Thermabate Cavity Closer - 3000mm Lengths - All Standard Thicknesses

• Specifically designed for use in England & Wales
• Maintains a continuous insulated cavity closer around door and window openings
• Simplifies construction by avoiding the need for cut bricks, blocks, or special reveal blocks
• Inhibited heat transfer reduces thermal bridging, condensation risk, and mould growth
• Weather-resistant, forming an integral DPC (damp proof course)
• Can be fitted with door/window frames as a combined unit

Masonry Cavity Walls: Kingspan Thermabate is ideal for masonry cavity walls due to its excellent thermal insulation properties. It helps to reduce heat loss through the wall, improving energy efficiency and reducing heating costs. Additionally, its lightweight and easy-to-install design make it a convenient choice for construction projects.

What is Thermabate?

Thermabate is a uPVC extrusion with a fibre-free rigid thermoset urethane (PUR) core, for use in England and Wales only. It is used to maintain continuous insulation around window and door openings in masonry cavity walls, and has a thermal conductivity of 0.034 W/mK.

Where do Cavity Closers go?

A cavity closer fits within a cavity wall, where windows and doors are fitted. Cavity closers are required for a number of reasons within a building to protect it from various factors, including water ingress, damp, heat loss and condensation.

Should you close a cavity wall?

Cavities should be closed both to provide an effective seal restricting the possibility of fire with the advantage of restricting heat loss through convection within the cavity. Safe-R Close-R provides compliance with thermal, fire and structural requirements.
