Description
Intumescent Multi Shutter Unit
A unique intumescent box for pipes, sealing off polypropylene and plastic pipes in ceilings, floors as well as walls. Ideal for use on plasterboard ceilings, also concrete. Made from powder-coated zintex metal and Envirograf multigraf intumescent to provide effective passive fire protection.
Our intumescent Multi Shutter Unit has been specially designed for rapid closing. The Multi Shutter Unit has internal veins held by a thermal wire. Once the pipe softens and starts to melt, the thermal wire breaks dropping down the four veins and shutting off the fire. The Intumescent expands, filling the whole box to seal pipes and reduce fire spread.
- Designed for pipes between 50mm to 400mm in diameter.
- Fit on to plasterboard or concrete ceilings where pipes pass through.
- The Multi Shutter Unit can be fixed to concrete ceilings and floors.
- When recessed, Multi Shutter Units require a faceplate to maintain integrity in the case of a fire.
- Supplied with adjustable brackets and also screws for fitting multi shutter units to surfaces.
