Benefits of Thermaduct

Low Air Leakage / Energy / Running Costs

The air leakage rate can be a fraction of that typical of insulated sheet metal ductwork – up to 80% less. This can yield significant electrical consumption savings because of reduced heating and cooling loads. Furthermore, over a 30 year life it can also make a saving of over 20% on operating 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-fibrousinsulation core, meaning they will resist attack from mould and microbiological growth and do not provide any food value to rodents or vermin.

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.


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

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.

UL Listed

This is the only 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.
