How to Install Thermaduct

Installing Thermaduct™ in your Application

Thermaduct duct systems are designed to benefit not just the building owner, but also those who install these systems both indoors and out. While we have a detailed Installation Manual available from our Thermaduct Representatives, 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. Thermaround uses the same UV stable 1000 micron vinyl cladding for a durable solution that will naturally shed water. In the interior, air passes over a smooth aluminum surface free from loose fibers to give your building better IAQ performance. Vertical Connections May Require Additional Sealant.
