Firebreak HITS I-Joists

by Joe Madera,

Boise Cascade has introduced the FIREBREAK HITS system to meet the 2012 IRC, Section 501-3 requirement that I-joist floor systems in unfinished habitable spaces of basements meet the 15-1/2 minute fire performance of 2×10 dimensional lumber.

FIREBREAK™ HITS HIGH INTUMESCENT THERMAL SHIELD OVER CERAMIC FIBERBOARD:FIREBREAKS’ High Intumescent Thermal Shield reacts to heat by automatically activating and expanding into a strong, thick heat shield. The ceramic fiberboard layer, protected by the thermal shield, guards the AJS® joist web in high heat conditions.

PASSED THE 15½ MINUTE FIRE TEST:FireBreak™ HITS has passed the E119, 15½ minute fire test as required to establish equivalency to dimension lumber joists.

CONSTRUCTION-FRIENDLY:No specific top and bottom orientation to help assure correct framing every time. Web holes may be cut the same as with non-protected joists. Non-corrosive to fasteners. Has met stringent durability standards required by the building code. Does not interfere with joist hanger installation.
