For sensitive areas and weather dependent applications, board is best

Rigid Board Fireproofing is the least used form of fire protection as it does not provide the cost effectiveness of SFRM or the aesthetics of IFRM. However, board applications can bring some key benefits that make it the right product for the right application.

Generally made of rigid mineral wool or cement base, board products are mechanically fastened around steel or other assemblies requiring protection. These boards once in place can provide long lasting performance with little chance of needing future maintenance. Fireproofing board has no installation temperature requirements, so it is a favorite for cold weather applications where heating the area is not a feasible option. This product can also be used on the exterior perimeter of buildings to allow for building facades to be installed in cold months with SFRM being used interior for an overall cost effective package that will not slow down the project schedule.

Rigid Board Performance Overview

Product Testing

All of the products that we offer have undergone rigorous testing by both ASTM and Underwriters Laboratory (UL) to verify their physical properties and determine their performance during a fire. UL fire tests are conducted on various construction assemblies and data is used to extrapolate a required thickness for each individual steel member based on the required hourly rating. Selection of the proper UL design for each project is critical in insuring that a building meets codes.
