Universal Graphite EPS Cavity Closers

Fully rigid insulated cavity closers provides a simple easy fit and highly effective method thermal break for closing cavities with dpc for around openings in masonry cavity and timber frame wall constructions

Categories: ,

Insulated cavity closers are an integral part of a cavity wall construction and are designed to fit within a cavity wall around opening such as windows and doors. Cavity closers are required to protec the openinf from cold bridging and damp ingress by forming a thermal break around framework to protect internally and reduce the risk of damp and condensation to prevent mould growth. 

• Simple easy and highly effective method for closing cavities around openings

• Will provide thermal insulation and prevent ‘cold bridging’

• Contributes to the reduction in damp and mould growth around openings

• Suitable for use in both new build and refurbishment

• Easy way to achieve Building Regulations compliance when closing cavities

• To satisfy NHBC standards

• Easy to install with simple cut to size indicators

• Exceeds accredited construction details of minimum thermal resistance path of 0.45m2 K/W

• Rigid profile extrusion will allow first and second fix installations

• Declared minimum thermal resistance path 0.95m2K/W

• Reduces risk of condensation, mould and moisture migration across the cavity

• Can be used on timber frame constructions

• Complies with Building Regulation Approved Documents C, L1 & L2
