The Dor Cav is a ground-breaking GRP structural cavity closer designed to support insulation and screed across cavity walls beneath external door openings. Developed as a purpose-built alternative to traditional infill methods, it provides a consistent, reliable solution where structural performance and thermal efficiency are critical. By eliminating the need for concrete or timber infill, Dor Cav helps reduce installation time on site while maintaining insulation continuity at the threshold. This makes it an ideal choice for modern construction projects working with wider cavity widths and stricter energy performance requirements.

Insu Clip provides a simple and reliable solution for securing perimeter insulation upstands, helping to improve consistency at the floor edge while reducing the risk of damage and displacement during the build.
