Life Safety Professionals work hard to develop and enforce building
codes to eliminate or reduce potential threats. Nothing can be more
frustrating and sometimes more costly than not having the correct
product to comply with the building code for your project.
Wood is a
Combustible Material
When you’re building a multi family residential project
using wood frame construction you’ll need to comply with
stringent requirements to prevent the spread of fire. These
are likely to include the use of fire rated products for ceiling
penetrations such as bathroom exhaust fans. Air King Fire
Rated Fans have been tested and are UL Listed for use in
wood frame construction and have been successfully tested
by UL in more truss designs than any major manufacturer.
You will see competitor certifications that will say “For use in any fire resistive floor or roof-ceiling assembly”.
That doesn’t necessarily mean UL listed for wood frame construction. Wood construction is NOT fire resistive;
wood is a combustible material that fire fighters usually consider fuel. The UL requirement for listing in this
case requires mounting and testing of the fan in each approved truss design above an actual fire. You know
you have the right product for the application when the manufacturer provides the truss design numbers for
which the product was tested. No design number - Not UL Listed for wood frame construction.
Air King Fire Rated Fans on the other hand are UL Listed
for the greatest number of wood frame truss designs
(see pages 25 and 26) at the time of this printing. Be
sure you have the right product and save yourself a lot
of time and trouble by starting with Air King.
