Pre-Insulated Ductwork
UL181 Certified
WT’s Pre-Insulated Duct remains unaffected by water, ensuring its insulation properties are maintained and preventing any added weight from retained liquid within the duct panels. Its mechanical flexibility allows for a perfect fit in any structure, making it a preferred choice for HVAC applications. Additionally, the duct is impervious to chemicals and features a closed-cell structure that inhibits microbial growth.
WT provides comprehensive services in the design, processing, customization, and production of pre-insulated duct systems and panels. We ensure tailored solutions to meet the specific requirements of your project. Our high-performing pre-insulated phenolic duct system, designed for both outdoor and indoor use, offers superior thermal performance and energy efficiency. This system is ideal for air distribution and insulated ductwork, providing high resistance to air leakage and significant weight savings. Our duct solutions, including the Pro R Indoor , is engineered to reduce installation time and minimize air leakage rates, ensuring optimal performance and energy efficiency.
Product Highlights
The first rigid phenolic pre-insulated ductwork in the world to be UL 181 listed as a Class 1 Air Duct, offers high performance and reliability.
A fiber-free, rigid insulation core minimizes the risk of loose fibers entering the airstream through the ductwork, ensuring clean and safe air distribution.
Low air leakage – easily achieves SMACNA Class 3 standards, providing efficient and effective airflow management.
Weighs up to 72% less than ductwork constructed from galvanized sheet metal and insulated with mineral fiber insulation, offering significant weight savings and ease of installation.

what are the main advantages of WT ductwork over insulated sheet metal?
Approximately 80% lighter weight than insulated sheet metal
Installation speed approximately 3 times faster
Thickness integrity of insulation all around the ductwork
Space and time saving with single-fix installation
It can be a very airtight ductwork – reduced air leakage and running costs
Reduced installed and life cycle costs
Clean air capability – air flows only on aluminium surfaces, no loose fibres
Reduced risk that moisture penetration may compromise the insulation performance
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.
Phenolic is a high performing alternative duct material that helps HVAC Contractors increase the thermal and duct leakage efficiency of their systems. Using phenolic also means that there is no need for separate ductwork and separate insulation as it is a 2-in-1 solution that does the job of both. For both interior and exterior applications, this duct material can offer many benefits for an installation.
