Insulated Fire Shutters

Leading supplier of insulated fire shutters

Insulated fire shutters are very similar to standard fire shutters, however they offer an additional radiation rating (EW) as well as a fire integrity rating (E). A radiation rating may be required to reduce the spread of heat transferring through the insulated curtain; these are designed to protect people and property. A typical example would be on an escape route where people need to pass the fire shutter in order to evacuate the building. The insulated fire shutter would also prevent radiated heat passing through and causing nearby materials to combust.

All insulated fire shutters are compliant to the new standard EN16034:2014 and are supplied with a certificate of constancy of performance.

    Why choose SSS industrial doors








    Working in the same operation as standard fire shutters, insulated fire shutters are engineered specifically to prevent some of the heat from transferring from one side to the other. This means if you have assets on the other side of the insulated fire shutter that are at high risk of being damaged by heat and more prone to melting, they are better protected due to the heat being retained on the other side of the shutter.

    It depends on the version, of which there are three. Our fire shutters can provide fire protection for either one hour, two hours, or four hours.

    They work in the same way, except an insulated fire shutter also prevents the transfer of heat from one side of the shutter to the other.

    An insulated fire shutter is manufactured from double-skinned 100mm galvanised flat lath. Strips of insulated rockwool are then inserted between the two interlocked sections of lath, which is then capped with steel end locks to prevent lateral movement. This forms a single section of the lath which, when interlocked with other sections, creates the whole curtain.

    If you have valuables and assets prone to melting or catching fire from condensed heat, insulated fire shutters are ideal to give that extra layer of heat protection by minimising thermal transmittance from one shut-off room to another.
