Clipsal 157FSW Flexible Fire Resistant Sealant for Wall Boxes
Clipsal 157FSW Flexible Fire Resistant Sealant for Wall Boxes
Genuine Clipsal fire resistant sealant, made specifically for sealing around wall boxes in fire rated construction. Every wall box in a fire rated wall breaches the barrier unless it is sealed with a rated product.
Features
- Fire resistant - maintains the fire rating of the wall
- Flexible when cured, so it accommodates building movement
- Purpose made for wall box applications
- Genuine Clipsal product
Why it matters
Cutting a wall box into a fire rated wall creates a hole in the barrier. Standard sealants and gap fillers burn through and will be picked up on a compliance inspection. A rated sealant restores the integrity of the wall around the box.
