What Insulation Is Best For A Camper Van?

When it comes to building a camper van, one of the most important aspects that many people tend to forget is insulation. This is one of your van build's most important aspects as it affects your comfort, your heat, and your money.

What type of insulation should I use for my camper van? There are various insulations that you can use in a campervan, but there are free that I think to work the best. Foamboard, fiberglass insulation, and spray foam all work very well as insulation for camper vans. There are few few few reasons why these work, and there are over insulations out there to consider, but overall these are the best.

Now that you know what insulations you can use in your camper, you probably have many questions about them. Questions like what makes these insulators the best? Is there no over insulation that I can use? How much is this going to cost for the insulation? Does insulation help with noise? These are all really good questions that I will answer for you in this article.

What makes these insulations the best for a camper van?

I like these insulations for campervans for a variety of reasons. These reasons range from the utility of the type of insulation to their price, to how easy they are to apply to your camper van. These reasons vary by the type of insulation, and I will go over each of them individually.

Foam board insulation

Foam board is probably my favorite insulator for campervans. It is a cheap style of insulation. The offer is good comfort without draining all of your money. It is also incredibly pliable, capable of being cut into various shapes to fit where you need to. Overall I think that foam board is your best bet for easy and good insulation in a campervan.

A quick look around online shows just how inexpensive foam board is for your camper van conversion, with a sheet of the name brand coming in at just $20. There are various brands that you can choose from and various sizes and amounts of sheets for you to choose from. This option gives you good versatility during the construction phase of your camper van.

Spray foam

Next, I would say spray foam is one of the easiest insulators to use and the cheapest in this article. The trade-off for this is that spray foam is not a traditional insulator like the others in this article. This is due to the nature of spray foam and what it is supposed to be used for.

Most of the insulations that are on the market are designed to be applied directly or near a surface to be insulation. Spray foam is designed to be sprayed on or around the surface to act as an insulator. Well, spray foam can be used directly as an insulator. It will take quite a lot of it to feel any voids are gaps and performed the same job. Well, this is possible. Many people prefer to use it to seal gaps and cracks in existing insulation.

A quick look around online shows that spray foam is the cheapest of all of the insulation options. It also shows through the feedback of many people who use it much of what I've described, then just might as a filler, not necessarily a full insulation.


Fiberglass is one of the most traditional insulation used for construction. It is most obviously used for home construction but can be very easily used for Van construction. There are a few reasons why fiberglass in insulation is used so widely today, and those are part of the reason I think it would work well for a camper van.

When it comes to fiberglass insulation, it has some of the most varied R values of any insulation that you can find on the market. This is why it is used in home construction all over the United States, is the different R values will by two different temperatures. There are also different styles of fiberglass insulation ranging from rolls and sheets to blown-in style insulation.

Fiberglass is the most expensive of the insulations that I have covered so far in this article. At base pricing, it can start at $20 and just go up from there. This depends on its r-value and how much of it you were buying in terms of length and number of sheets. The trade-off for the price is a higher quality of insulation.

Is there no over insulation that I can use?

There are several types of insulations out on the market today that you could apply for Van Construction. These insulations are ones that I am not familiar with, or I don't think it would work very well for what you were aiming for.

There are insulations such as denim insulation, which reminds me of the type of thick heavy insulation used under carpeting. I don't have a reason to think that this would not work in a campervan, but I have never used it myself. I can't recommend that you use it in your vehicle as I do not know how it would perform.

Then there are insulations like mineral wool insulation that function similar to fiberglass butter made of recycled components. Once again, much like the denim, I have no reason to think that this wouldn't necessarily work in a campervan. It is just not one that I can personally confirm would work.

The last type of inflation that I have seen our reflector panel insulation. Well, I do think that these would work particularly in blocking sunlight from heating your camper. I think they would lack in our areas, especially if you had to deal with exterior heat or the frigid temperature outside.

Does insulation help with noise?

Insulation does affect the amount of noise that you will hear inside or outside of your camper van. Whoever, this is just for the insulation itself, or you can choose to add sound dampening as you are constructing your vehicle. I think this is something you should be aware of and strive for as many people comment that Camper vans are subjected to noise all around them. With the right amount of insulation, you might not have to be woken up by every little noise outside of your vehicle.

How much is this going to cost in my camper van Construction?

I cannot put an exact figure on how much this will cost you, but there are some rough estimates that we can tell you depending on which insulation you choose. These are mostly based on the type of insulation Chosen and how much they appear to cost. Keep in mind that it varies depending on your van's size and how much insulation you use.

I would say that spray foam would be the cheapest of all of the insulation options. I would say that even in a good size van, you would not go above $50 and insulating the whole vehicle.

Foamboard, I think, is the best compromise between insulation and price. Depending on how many sheets you needed, I could see this costing anywhere from $100 to maybe $300, depending on your van's size.

Lastly, with insulation, it's difficult to say because inflation is larger but also more expensive. In truth, I think you'd be looking at $200 to $500 in price. Once again, depending on how much you bought and used in your van.

Keep in mind all of these are rough figures a little very much depend on what you choose to do and how much you choose to buy for your vehicle. Some people stay on budget or under budget, and some people can blow hundreds of dollars on insulation.

I hope this article helped you figure out which insulation you would like to go with for your camper van conversion. If you have any more RV or camper van questions, please feel free to look around the site. I have articles on everything from the best campers in each class to the basics of what a camper van conversion is.
