Fire classification

To BS EN 13501, B-s1,d0.

Brackets

All bracket types used in the Terrain Q system shall be specifically designed to reduce the passage of vibration from the pipe/ fitting surface in to the structure of the building. This can be achieved by the correct type of rubber lined bracket, the rubber lining being designed to optimize vibration de-coupling or, by de-coupling the connection rod back to the building structure by use of a proprietary anti-vibration bracket back-plate.
System brackets are provided within the Terrain Q range and are designed not to over-tighten on to the surface of the pipe; to avoid forming an acoustic bridge. Terrain Q rubberlined brackets reduce dB rating by 17. This is an average as over tightening will reduce the acoustic performance.
