Additional specifications and description
Fire-resistant collar designed for use with combustible plastic pipes. This collar is compatible with a wide range of pipes. The collar can be used for PVC-U pipes according to EN 1329-1, EN 1453-1 or EN 1452-1 and for PVC-C pipes according to EN 1566-1. The collar can also be used for PE-HD pipes according to EN 1519-1, EN 12666-1 or EN 12201-2 and for ABS pipes according to EN 1455-1.
The collar is water and frost-resistant, and maintenance-free once installed. It is easy to install as it supports different installation options - U/C, C/C (uncapped-capped, capped-capped). The collar is very aesthetically pleasing. Thanks to the cast-in mounting, it becomes virtually invisible and doesn’t take up any space inside the room.
Fire-resistant collars are used in cases where combustible plastic pipes pass through a wall or floor. Should a fire break out, these plastic pipes will burn and melt, leaving an opening in the wall. Flames and smoke can pass through this opening, causing the fire to spread to other rooms. Therefore, the function of a fire-resistant collar is to restore the fire-resistance grade of the penetrated wall to the same level as if it was solid. It can be said that their purpose is very similar to fire-resistant dampers. However, they are intended for use with combustible plastic pipes, rather than metal ventilation ducts. Because of their role in stopping the propagation of flames and smoke, fire-resistant collars have become an indispensable element of fire safety in modern buildings. Fire-resistant collars make it possible to maintain a smoke-free environment, even in the proximity of an active fire, allowing people to safely evacuate the building.
Construction and installation:
The fire-resistant collar is constructed out of a two-piece steel housing with a hinge and a fastener. This allows the device to be opened up and clamped onto a plastic pipe. On the inside of the collar are strips of intumescent material. When the temperature reaches around 150°C the intumescent material expands to many times its original volume and creates a barrier for the flames and smoke.
The collar is suitable for installation in solid walls, solid floors and light walls i.e. metal stud gypsum plasterboard walls. When installed in an oddly shaped or oversized opening, it is recommended to seal around the collar with stone wool boards. In general, care should be taken, when insulating the area around the fire-resistant collar, so as to not compromise the fire resistance of the wall. One of the advantages of this product is its compact size. Thanks to this, there’s only a minimal distance required between the collar and an adjacent wall, or one or more additional collars.
The fire-resistance rating of the device is between EI 90 and EI 180 depending on the installation method and the type of wall/floor material.
