For exterior openings where maintaining different temperatures on each side of the door is desirable.
Insulation: Slats filled with 7/8" thick pressure-foamed-in-place urethane insulation yield a curtain with a U factor of 0.125, R value of 8.0, both calculated according using the ASHRAE Handbook of Fundamentals. Closed cell urethane foam insulation provides the lowest thermal conductivity of any insulation commercially available. Weather Seal System including perimeter weathering at the head, guides and bottom bar cuts the air infiltration rate by 90 percent.
Applications: Freight doors, large vehicle doors, warehouse doors, power and water treatment plants. Also Sound Barrier doors below.
Sizes: Standard construction up to 30' wide, 30' high. Large openings to 38' wide, 40' high consult factory.
