Envirograf Intumescent Pipe Collar Summary

Envirograf Intumescent Pipe Collar

A hinged, two-part metal collar lined with intumescent material which expands in a fire. It has a quick-release pin to open the unit for fitting around a wide variety of metal or plastic pipes and cables. Such as (PVC, UPVC, steel and copper) and electrical cables that pass through fire-rated ceilings or walls.

Provides up to 2 hours fire protection for pipes from 45mm-650mm in diameter
Acoustic version offers both airborne and impact sound protection. 
Adjustable brackets allow for fitting in hard-to-access areas.

Application Instructions:
Access for fitting is available. 
Correct area of risk is assessed (double-risk areas may require two collars.
Correct size of collar appropriate to the pipe or service being protected.
The product must be installed correctly. Fixing lugs are already fitted to WPCS collars. They can be fixed to solid structures with raw plugs with screws. It is recommended that you pump a spot of Envirograf product 58 (intumescent Mastic) into the previously drilled hole. For hollow plasterboard walls, fix with screws if there are timber noggins to fix to, otherwise use steel toggle fixings. If WPCS are to be fitted into an area where no noggins or blockwork to attach to, the lugs can be re-attached to another part of the WPCS by drilling 1.5mm holes into the side of the collar and screw into collar. But all fixing brackets MUST be used even if you drill a fixing hole in a different position round the collar.
