Ductwork & Ventilation

Fabricated and installed for airflow performance and acoustic comfort.

Ductwork is the circulatory system of your building — and poor fabrication or installation causes noise, pressure loss, and energy waste. Our sheet metal shop produces custom spiral, rectangular, and fiberglass ductwork to SMACNA standards, with sealed joints and proper support spacing.

We fabricate supply, return, exhaust, and outside air ductwork for commercial kitchens, laboratories, healthcare facilities, and general office buildings. Specialty systems include fume hood exhaust, grease duct with welded seams, and cleanroom positive-pressure supply.

Installation crews work from coordinated shop drawings to avoid conflicts with structural beams, light fixtures, and sprinkler heads. We test every duct system for leakage per ASHRAE and SMACNA standards before insulation and concealment.
