For example, if width between joists was 400mm, then you would need to order a barrier with 500mm width. You will note that CCMC reports use the objective-based code language for alternative solutions where it is stated that the protected alternative joist performs "as well as" the inherent fire performance of exposed lumber floors. DC5040 is a water based thin film intumescent coating providing fire resistance to I-Joist and engineered wood framing members. 18 long fixing washers are supplied for fixing every 300mm apart per barrier. 18 long fixing washers are supplied for fixing every 300mm apart per barrier.

Furring. catastrophic collapse in a fire, regardless of the joist type, due to the fire’s intensity, the combination of joist spans and loads present, the location of serious structural fire damage or simply because it is too dark and/or smoky to see a sag in the floor. The latter has been determined in the US to be 15 minutes and 30 seconds, which is the time-to-collapse criteria to be met. Others have proprietary fire protection solutions for their specific alternative joist product. Since the NBC is not explicit on the fire performance of floors in single-family houses, the CCMC cannot make an exact equivalency to a specific NBC acceptable solution at this time. Apparently fire fighters have been hurt in house fires because the rate of burn on the I-joists is faster than traditional joists. Floor systems constructed with Open Joist™ floor trusses may be required to perform to minimum standards with regard to fire resistance and acoustical performance. Microllam LVL floor joists with dimensions of 1 3⁄4" x 91⁄ 4" or larger satisfy Exception 4 of the fire protection code, eliminating the need for additional fire protection. Designers and builders must be aware of this requirement when creating open ceiling basement living spaces. 8 FIRE PROTECTION The fire resistance requirement for a building and therefore the frame is defined in terms of the fire resistance period and stated in terms of minutes (15, 30, 45, 60, 75, 90 or 120 minutes). The ready-to-install I-joist is a safer solution for the floor above a basement, with wider nailing surfaces and longer, stronger spans for better floor … The latter has been determined in the US to be 15 minutes and 30 seconds, which is the time-to-collapse criteria to be met.
