When planning a van conversion, one of the first things to consider is how much Thinsulate is needed to insulate a Sprinter van. Proper insulation is critical for maintaining a comfortable interior temperature and reducing noise while driving or sleeping. Among the various insulation materials available, 3M Thinsulate van insulation is highly regarded for its effectiveness, ease of installation, and moisture resistance.
So, how much of it do you need for your Sprinter van? This guide will help break down the calculations for different parts of the van and explain why Thinsulate is a smart choice.

Why 3M Thinsulate is the Best Insulation for Sprinter Vans
Before diving into the numbers, let’s understand why 3M Thinsulate is so popular for van conversions. Many van-lifers choose Thinsulate over other materials due to its numerous advantages:
- Lightweight: Unlike foam or fiberglass, Thinsulate is incredibly light. This helps maintain the van’s fuel efficiency and ensures the insulation doesn’t add too much extra weight.
- Moisture-resistant: Moisture buildup can lead to mold, but Thinsulate prevents that by resisting moisture, keeping your van dry.
- Non-toxic: No need for special equipment or protective gear Thinsulate is non-toxic and safe to handle.
- Soundproofing: Beyond temperature control, Thinsulate also significantly reduces road noise, making your living space quieter and more peaceful.
Now, let’s get into the specifics of how much Thinsulate is needed to insulate a Sprinter van.
How Much Thinsulate is Needed for Sprinter Van Walls?
The walls take up the most surface area inside a Sprinter van, so they will require the most insulation. Here’s a breakdown:
- For a 144” wheelbase Sprinter van, you’ll need approximately 40-50 linear feet of Thinsulate to cover the walls.
- For a 170” wheelbase Sprinter van, you should plan for about 50-60 linear feet.
This should provide enough material to thoroughly insulate your walls and ensure you maintain a comfortable temperature inside.
How Much Thinsulate is Needed for Sprinter Van Ceilings?
The ceiling is another crucial area to insulate, especially since heat rises. A well-insulated ceiling helps trap heat inside during cold weather and keeps the van cooler in hot conditions.
- 144” wheelbase Sprinter van: Around 20-30 linear feet of Thinsulate will be needed for the ceiling.
- 170” wheelbase Sprinter van: For larger vans, prepare about 30-35 linear feet.
How Much Thinsulate is Needed for Sprinter Van Floors?
Insulating the floor can make a big difference, especially when camping in cold environments. The floor is where cold tends to seep in, and Thinsulate will help to block that out.
- 144” wheelbase Sprinter van: Around 15-20 linear feet of Thinsulate.
- 170” wheelbase Sprinter van: Expect to use 20-25 linear feet for full coverage of the floor.
How Much Thinsulate is Needed for Sprinter Van Doors?
It’s easy to forget about the van doors, but they are a critical area to insulate. Doors, especially sliding and rear doors, can let a lot of heat in or out, so it’s important to insulate these areas as well.
- Sliding and rear doors: You’ll need about 10-15 linear feet to insulate both the sliding and rear doors, regardless of the van’s size.
Best Glue for Thinsulate Installation
Now that you know how much Thinsulate is needed to insulate a Sprinter van, the next step is installation. Many DIY van builders wonder about the best glue for Thinsulate installation.
The recommended adhesive for installing Thinsulate is 3M 90 Hi-Strength Spray Adhesive. This spray adhesive works well with Thinsulate and ensures that the insulation bonds securely to the van’s metal surfaces.
Installation Tips for Using Thinsulate Adhesive
- Even coverage: Spray the adhesive evenly across the van’s surface and the Thinsulate.
- Press firmly: After applying the adhesive, press the Thinsulate onto the walls, ceiling, or floor.
- Allow drying time: Ensure the adhesive dries completely before adding any paneling or additional materials over the insulation.
Using the best glue for Thinsulate will ensure a lasting installation, providing your van with top-notch insulation performance.
Understanding the 3M Thinsulate R-Value
Another key aspect when selecting insulation is understanding the 3M Thinsulate R-value. The R-value is a measure of the insulation’s effectiveness at resisting heat transfer the higher the R-value, the better the insulation.
3M Thinsulate has an R-value of around 5.2 per inch, making it one of the most effective insulations for temperature regulation. This high R-value ensures that your van stays warmer in cold weather and cooler in hot conditions, without adding much bulk to your walls or ceiling.
How Thinsulate Compares to Other Insulation Materials
- Spray foam: While spray foam has a higher R-value, it’s permanent and difficult to adjust if repairs are needed.
- Fiberglass: Fiberglass has a lower R-value and tends to absorb moisture, which can lead to mold. It’s also bulkier and harder to install compared to Thinsulate.
How Much Thinsulate is Needed for the Entire Van?
To summarize, here’s a quick overview of the total amount of Thinsulate you’ll need for different sizes of Sprinter vans:
- 144” Sprinter van: Approximately 85-110 linear feet of Thinsulate for complete coverage.
- 170” Sprinter van: About 110-135 linear feet to insulate the entire van.
It’s always a good idea to purchase a little extra material to account for errors during installation.
Why Thinsulate is a Smart Investment
While Thinsulate may be a bit more expensive than other insulation materials, it’s an investment in the long-term comfort and efficiency of your van. Its combination of temperature control, moisture resistance, soundproofing, and easy installation makes it the superior choice for van insulation.
I’ve heard from many van-lifers who initially tried cheaper insulation options, only to experience mold issues or subpar thermal performance. One friend who started with fiberglass insulation ended up tearing it all out after just one winter and replacing it with Thinsulate. Not only did his van stay warmer, but it also became significantly quieter during long drives.
Final Thoughts on How Much Thinsulate is Needed to Insulate a Sprinter Van
In conclusion, if you’re wondering how much Thinsulate is needed to insulate a Sprinter van, you should plan for between 85 to 135 linear feet of Thinsulate, depending on your van size. Whether you’re insulating the walls, ceiling, floors, or doors, 3M Thinsulate offers the best performance for temperature regulation and soundproofing.
Don’t forget to use the best glue for Thinsulate, like 3M 90 Hi-Strength Spray Adhesive, to ensure a strong and lasting installation. With an R-value of 5.2 per inch, Thinsulate provides exceptional insulation without taking up valuable space.
Invest in 3M Thinsulate van insulation with confidence and enjoy a more comfortable, energy-efficient van living experience.
