Tested in horizontal and vertical orientation individually less than cellulosic (common time Vs. temperature curve) fire conditions and properly accomplished about 120 minutes of fire resistance for integrity and security of
In some cases contractors wrap ordinary air flow ducts with Rockwool or non-combustible insulation of any thickness/density.
Basic Characteristics of Fire Rated Ductwork Fire rated ductwork commonly has to go through compartment walls or flooring that could have a prescribed fire resistance period concerning the load bearing capability, integrity and insulation conditions, for durations of 30 to 240 minutes. It's really a necessity that where these compartment partitions/floors are penetrated by HVAC ducts or other setting up providers, the fire performance standards for the penetrated wall or flooring are managed, this sort of that fire in a single compartment may well not unfold to other parts.
We manufacture non-coated fire rated ductwork that's been examined to each BS specifications and EN specifications.
