Recycled PVC-U cavity closer for larger cavities
Recycled PVC-U cavity closer designed to meet the demand for closures in buildings with cavities 125–300 mm wide. Comprises a solid block of insulation (CFC/ HCFC free) making it ideal for low U-valve construction. With larger cavities being specified across new-build properties in order to meet stringent thermal efficiency regulations, BigBlok meets the demand for a simple slot-together system that quickly and cost-effectively closes off window and door openings of any size in any type of wall.
