Intumescent Pipe Collar by Envirograf

Advantages:

Due to its heavy duty nature, it is ideal for use in industrial buildings.
The acoustic version offers both airborne and impact sound protection.
Adjustable brackets allow for fitting in hard-to-access areas. 45mm, 55mm, 65mm, 225mm, and 250mm collars provide 2 hour protection; 75mm, 100mm, 127mm, 150mm, 175mm, and 200mm provide 1 hour protection – other options and sizes may be available, please call to discuss. 

Application Instructions:

Check:

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 (See also Envirograf® Product 110 for hollow wall fixing). 

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.
