Air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort.

A duct system is often called ductwork. Planning (laying out), sizing, optimizing, detailing, and finding the pressure losses through a duct system is called duct design.

Northwest Industries has an extensive ability to build and design all your ductwork needs. We use a unique designing tool with well over 300 different fittings, each we are able to tweak to your specific needs.

Mild steel is the standard and most common material used in fabricating ductwork but we can also use stainless steel and aluminum.
