Cast-in fire collar
H110S 110mm Cast-in Fire Collar
The most commonly specified collar in the range, sized for 110mm soil pipes, waste stacks and other plastic pipe penetrations. Cast into the slab before the pour and sealed by patented spring activation, restoring the floor’s fire resistance where a pipe passes through it.
Fire performance
Tested fire resistance by pipe type
All figures are from the BRE Extended Application Report P104650-1003 Issue 3. The last two columns are the EN 13501-2 classifications: insulation (EI) is how long the collar holds back both heat and flame, and integrity (E) is the longer period it keeps stopping flame and hot gases.
EN 13501-2
Tested to BS EN 1366-3. See the table for your pipe and configuration.
| Pipe type | Diameter (mm) | Pipe wall (mm) | End / socket wall (mm) | Insulation (EI) | Integrity (E) |
|---|---|---|---|---|---|
| PVC | 55 to 110 | 2.0 to 7.2 | 180 min | 180 min | |
| PVC with socket | 50 to 110 | 2.0 to 7.3 | 2.0 to 7.0 | 180 min | 180 min |
| PP | 50 to 110 | 2.1 to 3.8 | 120 min | 180 min | |
| PP with bell end | 50 to 110 | 2.2 to 3.8 | 2.2 to 3.8 | 180 min | 240 min |
| PE-HD | 50 to 110 | 3.4 to 10.9 | 120 min | 120 min |
