UPVC Cavity Closer System from Cavalok
100% post-consumer recycled PVC-U frame-forming cavity closers from Cavalok save time, money – and the environment
Cavalok PVC-U cavity closers are the simplest, most effective components for sealing cavities around openings in building walls. They are an essential component for any new-build project – large or small – helping to optimise time spent on site and boost the productivity of installation teams. The cavity closer provides a rigid template for brick and block work and facilitates straightforward, rapid window installation.
First choice for sustainability and energy efficiency
As demand for more energy-efficient and sustainable buildings increases, the role of cavity closers is becoming more important than ever. Cavalok cavity closers are manufactured entirely from post-consumer recycled PVC-U – meeting Code for Sustainable Homes and BREEAM standards. A pre-installed polystyrene core enhances thermal efficiency and cuts installation time, since no additional insulation is required.
Easy-install system compatible with all building types
The simple clip-together assembly delivers fast and accurate installation, with no need for adhesives or specialist tools. Cavalok cavity closers can be used with masonry, aluminium or timber building systems, making them the perfect choice for almost any building project.
