UPVC Cavity Closer Systems from Cavalok

100% post-consumer recycled PVC-U cavity closers save time, money – and the environment – on every building project

Cavalok PVC-U cavity closers are the simplest, most effective components for sealing cavities around openings in any wall – whether masonry, timber or steel. They are an essential component for any new-build project – large or small – helping to improve thermal efficiency performance, 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.

UPVC cavity closers from Cavalok offer:

• Product manufactured from 100% post-consumer recycled PVC-U from old window frames, for maximum sustainability. Using post-consumer recycled PVC-U reduces waste going to landfill, landfill taxes and raw material consumption.
• Pre-installed polystyrene core to enhance thermal efficiency for Part L compliance and save time on site, since no additional insulation is required.
• Time-saving clip-together closer assembly systems, guaranteeing fast and accurate installation with no need for adhesives or specialist tools.
• Quick-fit spring-clip systems allowing pre-glazed windows to be fitted very quickly – optimising time on site and improving installer productivity.
• Compatible with most PVC-U window systems. Also suitable for use with timber and aluminium window systems and off-site construction technologies.
