Installing Thermaduct™ in your Application

Installation is Easy - Connection Training

You can rest easy knowing you’ll find a 4-bolt connection system typical of traditional rectangular ductwork or an easy to use coupling system for round or flat oval applications. What’s uncommon about Thermaduct products is the steps we take to ensure customers receive an air tight system that also eliminates as many areas for water intrusion as possible.

Thermaround is our patented round solution for exterior applications. This high R-value system offers an R-12 solution with extremely low air leakage.
