Commercial Automotive Garage Spray Foam Insulation in Onalaska, TX
This project perfectly demonstrates the value of proper commercial spray foam in a heavy-duty industrial space. The owner of this massive metal automotive garage in Onalaska, Texas, needed a permanent solution to handle the intense East Texas climate. The building features tall ceilings, large roll-up doors, heavy steel framing, overhead crane systems, and an integrated interior office structure.
The Challenge of Commercial Auto Shops
Large metal shops present unique climate control challenges. During the summer, the vast expanse of bare metal roofing absorbs radiant heat, turning the shop floor into an oven and making it miserable for mechanics to work. In the winter, the cold metal sweats, leading to condensation that can drip onto expensive equipment, customer vehicles, and tools. Traditional fiberglass insulation sags, absorbs moisture, and ultimately fails in these demanding commercial environments.
The Spray Foam Solution
To permanently resolve these issues, Weeks Spray Foam applied a continuous layer of closed-cell spray foam across the entire interior envelope. As shown in the project photos, the foam was sprayed directly onto the corrugated metal roof deck and exterior walls.
Our crew meticulously worked around the building’s heavy infrastructure. We ensured clean, consistent coverage around the heavy structural I-beams, ceiling purlins, lighting fixtures, and the yellow Gorbel crane systems. The enclosed office structure in the center of the shop was carefully protected during the application, ensuring a flawless integration between the workspace and the climate-controlled office area.
The Finished Result
By using closed-cell foam for this metal building insulation project, we achieved three things at once: we established a rigid thermal barrier, completely air-sealed the envelope, and added structural integrity to the metal panels.
The building is now transformed from a sweltering steel box into a thermally stable environment. Whether the main floor utilizes large exhaust fans or a dedicated HVAC system, the heavy lifting of climate control is now handled by the airtight envelope. This is exactly how shop insulation and commercial garage insulation should be done to maximize energy efficiency and workplace comfort.
If you are constructing a commercial facility, agricultural building, or large workshop in the Onalaska area, getting the insulation right before operations begin is critical.
