UL 181 Listed Safety

Some Phenolic Ductwork systems have gone through extensive UL testing to achieve a UL 181 Listed status, starting with - Kingspan KoolDuct back in 2004. This is an extensive and rigorous series of tests and ongoing inspections that covers many aspects of safety and product durability - structural testing, pressure testing, mold and bacteria growth, static load and flame and smoke spread, among others.

Weight Savings

Ductwork made out of rigid phenolic foam can provide significant weight savings on your project. Indoor systems offer the highest savings, with rectangular, round and flat oval systems all capable of providing over a 70% reduction in weight compared with sheet metal wrapped in fiberglass.

High R-Values

Phenolic has an excellent thermal performance with some of the best R- values per inch of insulation available on the market .This superior insulating efficiency means that the required R-value can be achieved with thinner insulation. With the increasing pressure of energy codes always moving towards more insulation, Phenolic duct systems provide solutions that don’t only meet today’s code requirements but those of the future too.

Space Saving

Phenolic ductwork is pre-insulated, which means it does not require any additional insulation wrapping. Because of this, space requirements are minimal and duct can be installed in tighter places, including flush to ceilings and walls to free up more space. You may also need fewer hangers to contend with depending on the size of the ductwork.

Lower Air Leakage

Phenolic ductwork assembled and installed in line with the SMACNA Phenolic Duct Construction Standards can easily achieve anything between a SMACNA Class 1 and SMACNA Class 3 leakage rating. The long term benefits of this lower air leakage can include reduced runtime on HVAC equipment over the life of the system therefore bigger energy savings, better Indoor air quality with phenolic’s smooth aluminum interior and improved comfort.
