KoolDuct as an Insulation & Acoustic liner

Article content provided by Kingspan Insulation.

Where traditional metal ducts require multiple layers of insulation and acoustic treatment, KoolDuct simplifies the entire approach. Its closed-cell phenolic insulation acts as both thermal barrier and acoustic liner, reducing energy loss, dampening noise, and maintaining superior indoor air quality. The result is quieter, more efficient airflow and a cleaner installation without fiberglass, excess weight, or added installation time.

ASTM E477-20 testing confirms what the market has been demanding: reliable data around sound transmission, pressure loss, and overall duct acoustics. KoolDuct delivers on all fronts, helping engineers and contractors meet stringent building standards while improving comfort and system efficiency.

Use it as a high-performance airstream liner for plenum spaces, metal ductwork, & exterior duct systems, or rely on it as a UL 181 listed standalone ducting solution. No matter the application, KoolDuct gives you streamlined installation, enhanced energy performance, and a smarter way to design modern HVAC systems.
