Thermaduct Features
Compliance Testing
Thermaduct™ is comprised of a Kingspan KoolDuct fortified cladded duct system in accordance with requirements of factory-made air ducts. Thermaduct™ OD is specifically designed for use in outdoor applications where adverse weather conditions will occur. Thermaduct™ incorporates the following standards:
UL 723, UL 181, 90A, 90B Interior;
ASTM D-638, ASTM D790, ASTM D-256, ASTM D-4226, ASTM D-4216, ASTM D-792, ASTM D-2240, ASTM D-696, ASTM D-648, UL-94 Exterior Cladding
Frictional Properties
Thermaduct™ is a factory assembled air distribution system that employs a smooth aluminum surface that has frictional characteristics, much like that of galvanized sheet metal.
As a result, the frictional pressure drop data for galvanized sheet metal ductwork can be applied when designing and specifying Thermaduct™ air distribution systems.
Operating Recommendation
It is recommended that the application of Thermaduct™ supplied be utilized for operation as a supply, return, fresh air and exhaust air ductwork applications for heating, ventilation, and air conditioning applications.
Air Velocity (Maximum) - 5000 fpm / 25.4 m/s
Design Pressure (Maximum) - Positive and Negative 10 / 2500 Pa (Proper reinforcement required)
Temperature - Internal; Continuous -15°F to +185°F
Size Limitations - None
Thermaduct™ can be designed to withstand up to a continuous maximum static pressure of 6 inches water guage / 1500 pa and is designed to have less than a SMACNA Air-Leakage Class 1 duct with the Thermaduct™ connection system.
By combining two layers of an autohesively bonded aluminum foil vapor barrier to the inner and outer closed cell Kooltherm insulation core, all protected with 1000 micron UV stable vinyl clad with welded or cohesively bonded seams, you simply can’t find a more air or water-tight outdoor duct system anywhere.
