How do you apply the Envirograf Pipe Collar?:
- 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 and screws. It is recommended that Envirograf product 58 (intumescent Mastic) is firstly inserted 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 are present 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 screwing into the collar.
WPCS’s MUST be securely fixed.
