Ready to use cavity closer insulates, closes and protects reveal against damp ingress. Insulating core is uniquely shaped to link with partial fill cavity insulation
Available in 2400mm lengths to suit cavity widths from 100mm upward.
Hidden once built into reveal and window or door frame built in
The only UK closer with a cranked insulating core that wraps across the face of adjacent partial fill cavity insulation and in so doing blocks the heat loss path via gaps that are regularly observed between closers and cavity insulation. Thus can be used to aaddress concerns in L1A 5.9 that states there shall be no reasonablyb avoidable thermal bridges caused by gaps.
New build applications, domestic, commercial and educational structures.
