Lift shaft fire protection for landmark tower block

Heron Towers, central London

Heron Towers is a prestigious, 46-storey office building in central London, where open lift shafts with fully glazed lifts were installed during its construction. Cryotherm was chosen to provide two-hour fire protection, with a decorative finish, to the lift shaft’s steel frame.

Rockliner casings were the ideal choice and the colour Metallic Silver PVDF was specified by the architect.

The project included pre and post-sales site surveys, technical advice, fabrication of casings and support framework and the installation, which was undertaken by our approved contractor, Firesafe Installations Ltd.
