Koolduct

• Pre-Insulated for Single Trade Installation
• Increased Energy Efficiency
• Reduced Heating and Cooling Loads
KoolDuct is designed to save you money on the job site too. Phenolic-foam panels come pre-insulated and can be assembled in significantly less time than sheet metal ductwork. Combine KoolDuct’s inherently low leakage with its superior insulating properties and you’ll appreciate significant energy savings via reduced heating and cooling loads

• Airtight Efficiency
• Higher R-values
• Protected Airstream
KoolDuct insulated panels deliver impressive air-tight
efficiency, excellent thermal performance. The closed
cell phenolic foams and thermal conductivity is an impressive 0.13 BTU in/hr ft2. The air stream in the fully sealed duct flows only on aluminum, ideal for high specification application and on jobs where a non-fibrous solution is desired. As a UL 181-rated system, it easily meets SMACNA Leakage Class 6 for high pressure ductwork.

• Reduced Installation Time
• Space Saving
• Lightweight
KoolDuct is incredibly lightweight–only 3.5 pounds per cubic foot,
which is 15% of the weight of insulated sheet metal. So it’s easy to install, and a lot faster than sheet metal. The single – fix installation, eliminates the need for two trades. And KoolDuct can also be installed flush against the slab delivering more space savings than traditional sheet metal ductwork–up to 6-8 inches.

Notes

DESCRIPTION

The Knauf KoolDuct® System is a pre-insulated, high performance air duct system for industrial and high-end commercial applications. The system uses a CFC-free phenolic foam board faced on both sides with reinforced foil. Patented, specially engineered, aluminum flanges are designed to connect the duct sections to assure a strong, tight closure.

APPLICATION

The Knauf KoolDuct System is used in commercial, residential and industrial applications. The ducting is versatile and can be installed internally or externally, and concealed above a false ceiling or visibly mounted. It is easily modified and repaired and can be fabricated on-site with non-powered tools.
