Valsir · Firestop collars
COLLARWINGS 240
Steel-framed firestop collar for plastic waste and rainwater pipes. In a fire the collar expands, squeezes the pipe shut and prevents flames, smoke and heat from spreading through the penetration. Thanks to the hinge and latch design the collar can also be retrofitted onto existing pipe runs.
Product information
- Fire resistance class EI 240 (EN 1366-3), diameters 32-160: resistance to fire, smoke and heat transmission for at least 4 hours
- Large diameters 200–315 mm: fire resistance class EI 120
- Installation in walls or floor slabs, also on existing pipe runs (latch mechanism, pre-drilled mounting plate)
- Suitable for PP, HDPE, ABS and PVC pipes and for the sound-insulated Triplus and Silere systems
- Tested to EN 1366-3: concrete wall and slab (reports CSI1917FR, CSI1862FR, CSI1915FR); drywall EI 60/90/120 (CSI1983FR)
