Whether it’s your work van, camper, or you use it for transporting specialty goods, you’re considering spray foam insulation for your cargo or sprinter van.

There are a ton of benefits to having the right cargo van insulation, including reducing noise, thermal resistance, and protecting the items you haul around.

RetroFoam of Michigan has been in the insulation business for more than 20 years. In that time, we’ve had dozens of cargo and sprinter vans come through our shop for spray foam insulation installation.

In our continued efforts to educate the public on foam insulation, we have compiled all the information you will need when thinking about insulating your sprinter or cargo van.

Why Cargo or Sprinter Van Insulation and the Problems it Solves

There are a lot of different reasons to insulate a cargo van, but it really comes down to what you’re using it for.

As stated above, the most common vans we insulate are work vans, converted campers, and vans used for hauling specialty items.

Work Vans

One of the big advantages of insulating your work van is sound deadening.

Any time you have a cargo or sprinter van that is all metal inside, you’ll have a noisy van, especially if you have a tool rack on the sidewall because your tools will be clanking against the metal sides.

Closed cell spray foam on the walls will reduce that clanking noise and echo, making for a much quieter ride to and from job sites.

Camper Vans

Instead of dropping big bucks on an RV, many people are converting their vans into a camper.

In this case, you get more into the traditional uses for insulation, like comfort and thermal resistance.

Keeping that cold or heat out while camping can make or break your trip. Spray foam insulation will create the air barrier you need to make sure you are nice and cozy while enjoying the great outdoors.

Transport Vans

Depending on the materials you are transporting, you may need to keep them and your van safe.

For example, a customer asked us to insulate their van because they were transporting saltwater fish tanks. The foam insulation kept the tanks from bumping against the metal sides of the van but also protected the metal from the corrosiveness of the salt.

Again, it all depends on what you’re using the cargo or sprinter van for and how the foam insulation can help you achieve your goals.

How to Insulate the Inside of a Van with Spray Foam

The best way to insulate a cargo van is by spraying the walls, back doors, and ceiling with closed cell spray foam.

There are some instances where the floor is sprayed as well, but usually, that is left unsprayed as there is already a protective coating on the floors.

When insulating a van, we choose closed cell spray foam over open cell for a few reasons.

Mainly because of the durability. Typically, when insulating a cargo or sprinter van, you will leave those walls, ceiling, and backdoor exposed. This means you’re going to be bumping into it, and sometimes you’re going to drill through it to attach a shelf. You really need a material that is really durable and can keep up with your needs – closed cell does that.

If open cell spray foam is used and something bumps or brushes it, it will tear the open cell up because it is a softer, more pliable material. Closed cell spray foam is very rigid and dense, so it can hold up to being banged or poked.

Cargo or Sprinter Van Spray Foam Insulation Process

The process of insulating a cargo van is basically cleaning it out – taking everything out of it.

There’s usually some manner of dividing wall that separates the cab, which isn’t usually sprayed.

In preparation for the installation, the crew will remove everything from inside the van behind the dividing wall. If there are platforms or shelving brackets, they are often taken off so the installer can spray around where they are housed.

Next, the areas to be sprayed are prepped. For example, if there are drill holes where shelves attach, we would cover those and make sure they don’t get sprayed over.

Finally, the ceiling, walls, and backdoor are sprayed.

How Much Does it Cost to Insulate a Cargo or Sprinter Van with Foam Insulation?

The price can range because it all comes down to the square footage to be sprayed.

The cost to insulate a sprinter van or cargo van with closed cell spray foam insulation starts at $1950.

Other factors also determine the cost, including if the van is brought to our shop and the amount of spray foam installed. The above price is based on two inches of closed cell spray foam, which requires an air seal.

Spray Foam Van Insulation FAQs

You might still have some questions, and that's okay because we have the answers.

Here are some of the questions we get asked most often about spray foam van insulation.

Is Foam Insulation Safe?

The foam insulation we use, both injection and spray, are safe to use in your van, home, or pole barn.

Will Foam Insulation Damage the Van's Metal?

Although it’s not that common, there is the possibility that the spray foam could slightly bow out the outer wall.

However, this doesn’t damage the van at all.

Another concern is that the closed cell spray foam will rust the metal. Between the expertise of our installation crews and the materials we use, this isn't a concern.

Can I Still Hang Panels in My Van with Spray Foam?

Yes. The foam is applied at only two inches thick.

During installation, we are careful not to cover the fastening points.

What About Insulating the Van Floor?

We recommend this because it makes a big difference.

Keep in mind that it adds cost to the project and should be framed out.

How Should I Prep My Van to be Insulated?

All of your furniture should be taken out and the door panels removed.

All wiring should be taped or zip tied together. Also, make sure the van is as clean as possible.

How Long Will it Take to Spray Foam My Van?

The time to spray foam in your van will range between 2 to 4 hours.

Is it Safe to Drive My Van the Same-Day it is Insulated?

Absolutely. The workspace where the van is insulated is ventilated during the installation.

With this being said, there still could be a lingering odor, but it is safe to drive that same day.
