When spraying is not a practical approach to providing fire protection due to out of sequence construction, space constraints, freezing temps or time limitations, Fire Resistive Board can also be considered for passive fire protection. Protecting structural steel in your building during construction in the cold weather months can present a number of challenges that can be avoided with the use of Rigid Board Fireproofing. This passive fire protection option does not require the use of machines, pumps, or water as it is attached directly to the steel beam, column, or deck surfaces. Therefore, installation can occur without heating, masking, tarping or ventilating the work area which helps to minimize a non-budgeted expense.
Rigid Board Fireproofing can be utilized on roof deck areas where construction roof traffic is unavoidable. Since Rigid Board Fireproofing is mechanically fastened to structural steel decking, (as well as beams and columns) these materials are unaffected by construction root traffic. Such a system should be considered carefully when determining the overall construction schedule. Rigid Board Fireproofing can withstand temporary exposure to weather helping to eliminate the need and associated costs of potentially patching and re-patching the same steel with Spray-Applied Fireproofing if damaged by inclement weather.
Fire Resistive Board fireproofing allows for the installation of passive fire protection without interruption to the construction schedule. It can provide up to 4 hours fire protection for columns, up to 3 hours protection for beams and floor/ceiling assemblies and up to 2 hours protection for roof assemblies in commercial and industrial construction.
Fire Resistive Board can be used in conjunction with Spray-Applied Fire Resistive Materials (SFRMs) to protect perimeter beams and columns to allow for the building to be enclosed prior to the application of the SFRM.
