FYYB Specifications

Furnish and install louver as hereinafter specified where shown on
plans or as described in schedules. Louver shall be stationary type
with horizontal rain resistant style blades positioned on approxi­mately 2” centers within 4.162” deep frame. Louver frame and
blade materials to be .081” thick 6063-T5 extruded aluminum.
Sections up to maximum of 60”w x 96”h shall withstand wind load­ing of 30lbs/sq.ft. (110 mph wind equivalent). Consult factory for
welded construction and higher wind speeds.

Louver shall meet the performance requirements established by
the AMCA 500L test procedure and shall be licensed to bear the
AMCA certified ratings seal for water penetration, air performance,
and wind driven rain. Louver shall have a maximum static pressure
drop of .23” (exhaust) and .31” (intake) water gage based on 1000
FPM free area intake velocity. Louver shall carry a Class C water
penetration classification based on a ventilation core of 573 FPM at
a rainfall rate of 3” per hour and a 29 mph simulated wind velocity.
Louver shall carry a class D water penetration classification based
on a ventilation core of 294 FPM at a rainfall rate of 8” per hour
and a 50mph simulated wind velocity.

Beginning point of WATER PENETRATION
is 722 fpm free area velocity at .01 oz. of
water penetration
