Cavity Barriers at Watermark, Hackney

Our SCT cavity barriers provide internal passive fire protection for buildings

The 8-storey canalside building comprises over 35,000 sq ft of workspaces and 33 residential units comprised of 1, 2 or 3 bedroom apartments above. The site is situated by Regent’s Canal and close to Broadway Market. To prevent spread of fire Envirograf® Sealed Cavity Tray was installed.

Envirograf designed a specific corner piece that can be used on return corners of buildings. This has been designed so it provides a secure fit around the corner of a building and is still flexible and also completely water proof. This corner piece can be bedded into the block or brick work during construction or we can supply washers and screws if you wish to screw it to the inner wall/timber. The corner piece is supplied 50cm long on each side but it can be made any width or size. The SCT can be cut and rejoined using our red joining tape.
