Powerful intumescent sealant for sealing voids around services passing through fire-rated surfaces.
EN/F is a powerful fire-resistant intumescent sealant filler, available in dark grey and also white. Ideal solution to seal gaps around penetrations in both hollow and solid walls, including floors and ceilings.
Tested for 2 hours fire protection and insulation in plasterboard hollow walls and brick, block walls.
- Suitable for use with aluminium, copper, plastic and steel pipes up to 50mm diameter
- Can also be used for cables (including armoured cables, MICC and flexible cable types) up to 32mm diameter
- Made of water-based materials which become water-resistant once cured
The cartridges marked EN/F1 (the dark grey intumescent graphite compound) are for filling around the services from 30mm into the hole and up to 10mm from the front surface.
In plasterboard walls the hole must be 40mm larger in diameter that the services passing through. For example, a 50mm diameter pipe would require a hole size 90mm in diameter.
For brick, block and concrete ceilings and walls the hole must be 30mm larger in diameter than the service. For example, a 50mm diameter pipe would require a hole size 80mm in diameter.
