How to Select a Good Spray Insulation Foam Trailer

By Kevin Malone

Buying a spray insulation foam trailer is a major investment for your contracting business, so you will want to make sure you make the right choice. The type of jobs you do and how often you plan to use your spray foam trailer will make a big difference in getting the right fit for the job.

The experts at Intech Equipment and Supply can guide you to make the best decision. Intech’s professional spray foam equipment specialists have helped hundreds of contractors find the right equipment, design and build for the perfect spray foam trailer for their business.

Here are some of the key things you will want to consider for your spray foam trailer.


You will need to estimate the payload you will be carrying to safely transport your trailer for spray foam insulation jobs. Make a list of the equipment, materials, tools and accessories you will have on board and determine the total weight. Make sure you estimate with full loads of chemicals, equipment, cleaning supplies, tools and anything else that will go in your trailer.

Think about any future plans you may have to add additional gear or expand. You will want to make sure you get a trailer that can handle the weight comfortably and still leave some room for growth. Weight distribution is also critical for safety and stability. If you are pulling a trailer, the ideal balance is about 10% to 15% tongue weight.

Size and Dimension

When it comes to size, you will want to select a trailer that can comfortably hold everything you need and allow for easy access. Remember that you may be moving around inside the trailer wearing bulky equipment, so leave a little extra space.

Larger trailers can hold more equipment but may also limit you if you take jobs where you need to fit into tight spaces.


Spray insulation foam trailers are typically built of steel, aluminum or fiberglass. Steel is the most durable, but it is heavy. Aluminum is lighter yet generally requires reinforcement. Fiberglass is ultra-light but may not stand up to moderate to heavy use.

If possible, look for a double-layer underbelly for additional storage and protection. If you plan to walk or stand on the roof during applications, you will want to pay extra attention to roof strength.


Spray foam chemicals need to be stored at specific temperatures for optimal application. Thermal insulation helps control conditions inside the trailer, whether it is hot or cold outside. Polysio Board provides good insulation at a reasonable cost, but spray foam insulation will have the highest R-value.

Electrical Systems

Consider generators for self-contained power or shore-power hookups. Do not skimp on your generators. If you do not have sufficient power or it is unreliable, it can shut down jobs fast.

You will also want to ensure you have enough power to handle the full load, including your equipment, temperature controls, lighting, ventilation fans, and charging stations.

Spray Foam Rigs

You will also want to carefully plan the equipment that goes inside your trailer for spray foam insulation jobs. You need to properly outfit your rig for optimal production. Some of the key components you need may include:

  • Proportioners
  • Heated hoses
  • Spray foam guns
  • Transfer pumps
  • Generator
  • Hoseracks, chemical tanks, or Drums
  • Drum heaters
  • Compressor
  • Air conditioning and heating
  • Storage


How you position your equipment matters greatly. You want to make sure you leave enough room to work around equipment, especially for tools you need to get to quickly. For example, consider mounting safety equipment in key locations for ready access.

Storage racks, cabinets, and other accessories can help make your workspace more efficient and comfortable.


If you are starting from scratch, you have plenty of options for how you lay out your spray foam trailer and mount your equipment. Built-in rigs, ventilation systems, and ample storage can make your job easier.
