Cavalok Building Products

Cavalok was the first company to manufacture cavity closers entirely from 100% post-consumer PVC-U, meeting the growing demand for more environmentally friendly building products.
Cavalok cavity closers are now one of the most widely used post-consumer recycled building products in the UK.
We have also developed the advanced BigBlok cavity closer to fit the wider cavities increasingly being specified to achieve improved thermal efficiency in buildings.
In fact, our innovative products have been used to build new houses that achieve Level 6 in the Code for Sustainable Homes. Our commitment to constantly improving environmental best practice remains undiminished.
