How Much Does It Cost to Build a Spray Foam Rig?

By Kevin Malone

For commercial spray foam insulation contractors, properly equipping a mobile spray rig is key to both efficiency and productivity. If you clicked on this headline, you are likely looking for what that will cost, so we will answer that question first.

Average Cost of a Spray Foam Rig

The average price of a basic spray foam rig starts at about $40,000. Fully equipped trailers with high-end equipment can cost $150,000 or more. Finding the right setup for your business is critical to maximizing your productivity and profits, and there are a lot of considerations that go into finding the right fit.

Several factors affect actual costs, including:

  • Size of the trailer: Larger trailers cost more but can handle larger jobs.
  • Equipment quality: Higher-end equipment drives up cost but may significantly improve output.
  • Additional features: Adding things like climate control, storage capacity, or customization will increase spending but can increase efficiency.

How much you need to spend requires balancing needs and budget. So, we need to go a bit deeper into each of the areas that impact cost to help you make a better decision about which type of spray foam insulation rig is best for you.

Choosing the Right Trailer

The first major decision is choosing the right base trailer to meet your current and future business needs. The ideal trailer size balances storage capacity and maneuverability, scaling up or down based on your crew size, job capacity, and amount of equipment. It is also essential to opt for durable, heavy-duty trailer construction to withstand frequent transportation and loading/unloading.

Additionally, look for customization options to tailor the layout and storage solutions to your workflow. Intech Equipment & Supply builds customized and turn-key spray foam rigs so you can get the exact configuration you want.

Trailer Insulation

Once you’ve selected the base trailer, one of the top priorities should be heavy insulation. Thoroughly insulating the walls, ceiling, and floor helps maintain consistent internal temperatures. This protects foam materials from external climate fluctuations that could compromise quality and performance.

Going a step further by installing air conditioning units allows active temperature regulation inside the trailer.

Equipment Placement and Storage

When designing the trailer interior, strategic equipment, and storage placement promote an efficient workspace.

Heavy equipment like the foam reactor should be centered to evenly distribute weight to ensure safe transport. You also need to securely anchor other equipment, such as hoses, generators, and compressors, to prevent shifting while traveling.

Intuitive storage solutions, like shelves and racks, enable easy access and quick restocking of tools, safety gear, and cleaning supplies.

With more than 150 combined years of spray foam experience,: the professionals at Intech Equipment & Supply know how to configure a spray foam rig for the ideal layout.


Spray foam application can be hazardous, so make sure safety equipment is visible and quick to find when needed. Incorporating features like proper ventilation, fire suppression systems, and ample lighting can make a big difference in protecting your team.

How Much Should I Spend on a Spray Foam Insulation Rig

When considering a spray foam rig for your business, you will want to look at the total operating costs of your equipment. You do not want to save a few bucks upfront if operating the rig will cost you more in the long run.

Some areas you need to consider include:

  • Fuel costs
  • Insurance premiums
  • Maintenance and repair
  • Solvants 
  • Depreciation
  • Training
  • Storage fees
  • Taxes and registration

The ideal spray foam rig maximizes output while keeping operating costs optimal. You will want to analyze any rigs you are considering in terms of TCO, as well as projected equipment capabilities and process efficiencies. This balanced approach helps ensure the selected rig can deliver the best return on your investment through maximized performance.
