KoolDuct Ductwork Features and Benefits

UL Listed

Rigid phenolic pre-insulated ductwork in the world to be UL Listed as a Class 1 Air Duct to Standard for Safety UL 181. To meet Class 1 Air Duct requirements, ductwork must withstand rigorous physical tests such as: burning, flame penetration, mold growth, puncture, pressure, corrosion, erosion, static load, impact, collapse, air leakage, and low and high temperatures.

SMACNA Phenolic Duct Construction Standards and KoolDuct

In February of 2015 ANSI Accreditation was awarded which opens the door for KoolDuct and Thermaduct phenolic ductwork to become specified by architects, engineers, and owners without the risk of using a product that lacks these attributes.

KoolDuct demonstrates the technology of the new SMACNA Phenolic Duct Construction Standards.

Lightweight

The exceptional strength to weight ratio of ductwork fabricated results in ductwork that is easier to handle and quicker to install. Weighs 72%-85% less than sheet metal ductwork, it can overcome severe constraints on structural loadings in older buildings that cannot support additional weight.

Highest R Value to Size Ratio on the Market

The thermal conductivity (k-value) of Kingspan KoolDuct® panels is 0.146 Btu·in/hr·ft^2·°F at 50°F (ASTM C 518), the lowest of any commonly used insulation material. A low thermal conductivity allows thinner insulation to achieve the required thermal performance. The installed material thermal resistances (R-values) for the range of panel thicknesses are shown in the table below:

Space Saving

Can be installed flush to the ceiling eliminating the space required for the manual process of applying the insulation above the ductworks as a second fix. This can save up to 6″-8″ of valuable space.

Faster Installation

The ability to fabricate ductwork in up to 13 ft. long sections means fewer sections and less handling. This combined with the requirements for fewer supports and its single fix installation results in a fast track installation, up to three times faster. Faster installation obviously means lower costs and less disruption for other trades on site.

Installed Cost Savings

The installed cost can be up to 19% cheaper than that for insulated sheet steel as a result of reduced material and labor costs.

 

Indoor Air Quality

Distributed air flows over sealed aluminum surfaces, minimizing any risk of loose fibers entering the handling systems. The panels have a non-fibrous insulation core, meaning they will resist attack from mold and microbiological growth and do not provide any food value to rodents or vermin.

Moisture Resistant Closed Cell Technology

The insulation core of Kingspan KoolDuct® panels has 90% (or greater) closed cell structure, which means that they are non-wicking and highly resistant to moisture penetration. In addition, the risk of moisture absorption into the core is effectively eliminated as the factory applied aluminum foil facings provide a high performance and impervious vapor barrier. The panels have a water vapor transmission of 0.34 grains/hr·ft^2
