Vibrations, Cold, Noise: Insulate Your Van Like a Pro in 4 Steps

May 13, 2026

Complete van insulation is essential for handling all temperatures and traveling with as few limitations as possible. Good insulation not only keeps you at the temperature you want, but also absorbs vibrations and protects you from outside noise.

Using Van d'ici's insulation collection gives you everything you need to set off on an adventure. Whether you drive a Sprinter, Transit, or Promaster, good insulation will ensure comfort and a welcoming atmosphere in your converted van.

With this four-step guide, you can install four-season insulation yourself that also effectively prevents condensation.

STEP ONE: Dampen vibrations with DETOUR LAB vehicle sound-deadening material
 

The first step to achieving complete insulation in your van is to dampen vibrations using DETOUR LAB sound-deadening material. This self-adhesive mat features a three-layer composite structure. The outer face consists of laminated aluminum foil. The middle layer is 2 mm butyl rubber. The back is coated with high-adhesion acrylic adhesive.

Once the metal is clean and degreased, you can remove the protective film. Then press the sheets onto the desired areas. Simply apply the DETOUR LAB panels directly onto the bare metal, whether on the walls, doors, or floor. You don't need to cover the entire surface. Covering just 25-30% of the total surface area is enough to dampen panel resonance.

The Role of DETOUR LAB Sound-Deadening Material

DETOUR LAB sound-deadening material is available in 30 x 40 cm sheets. Each pack contains 34 sheets, covering 4.08 m2.

Its main role is to stop vibrations at the source, such as road rumble, body resonances, and low-frequency engine noise. It also withstands temperatures from -20°C to +120°C.

However, it has its limits in terms of thermal coverage, and that's where Thinsulate comes in.

STEP TWO: Thermally insulate and absorb sound with Thinsulate 

Next, now that your van is soundproofed, it is time to insulate it using 3M Thinsulate. These products are available for Sprinter, Transit, and Promaster vans in seven different sizes.

To apply this material, spray the 3M 90 spray adhesive onto the Thinsulate and the wall to achieve optimal adhesion. It is recommended to apply the adhesive in small sections at a time and wait 30 to 60 seconds for it to become tacky. Then, you can apply the sections of Thinsulate and press them into place. The white side is attached to the metal, while the black side remains exposed. Finally, fill the structural cavities using a flexible rod or wire.

Advantages of Thinsulate 3M

Thinsulate insulation is made of hydrophobic synthetic microfibers, making it resistant to mold and moisture. This is particularly important because the inside of a van can quickly become a very humid environment. It provides thermal insulation as well as sound absorption at mid and high frequencies, such as wind noise and whistling. This therefore completes the soundproofing.

The combination of Thinsulate and DETOUR LAB butyl rubber provides complete soundproofing and insulation. This reduces the strain on the heating system in winter and limits overheating in summer. Your vehicle is therefore ready to take on all four seasons.

These materials were designed to be as lightweight as possible so as not to overload the vehicle. Their quality meets the requirements of the automotive industry and makes them perfectly suited to vans, which is why they also comply with the FMVSS 302 standard.

THIRD STEP: Prepare the insulation surface for finishing with Landau Foam 

The third step is to prepare the surface for finishing using 1/8" Landau Foam. To install it, glue it to the plywood panels, again using 3M 90 adhesive. This step fills gaps and imperfections, softens edges, and creates a smooth surface before applying the fabric. It also provides a slight cushioning effect.

Benefits of Landau Foam

Landau Foam is made of thin, closed-cell cross-linked polyolefin foam. This product offers excellent thermal and acoustic insulation and vibration-dampening properties. It perfectly complements the materials used in the other steps and ensures a high-quality finish.

This foam is ideal for padding because it is thin, durable, and strong. It is 60" wide and 1/8" thick. Like the other products in the insulation collection, it is water-repellent. It's ideal for van conversions in Quebec.

FOURTH STEP: Upholster and finish with ENDUREPEL or AEROTEX interior van fabric
 

The last step, but no less important, is to enhance the vehicle's appearance and make your van as comfortable and cozy as possible.

For the finishing touches, you can choose between two fabrics: either ENDUREPEL Medley or AEROTEX. ENDUREPEL Medley is available in 4 colors and is resistant to stains and dirt. It is even antibacterial and easy to clean. AEROTEX, meanwhile, is made of tweed, is available in 13 different colors. It is also resistant to stains and dirt. It is designed for heavy-duty use and has been treated to repel water and stains. It is durable and easy to maintain.

To apply them, cover the panels with ENDUREPEL or AEROTEX fabric, then staple or glue it in place, depending on the area inside your van.

This fourth step ensures an attractive and durable finish for your vehicle. These products were also designed for automotive use, which is why they are lightweight and won't take up space in your converted van.

The Best Way to Insulate Your Van

By following these four steps and using the recommended products (DETOUR LAB sound-deadening material, Thinsulate, 3M spray adhesive, Landau Foam, and ENDUREPEL or AEROTEX finishing fabric), you can fully insulate your vehicle. 

Not only will your Mercedes-Benz Sprinter, Ford Transit, or Ram Promaster conversion van be insulated, but it will provide excellent soundproofing, both against outside noise and vehicle vibrations. All with a flawless finish and an appearance that makes the van feel welcoming. Even with the addition of several materials, these products are specially designed for vehicles and therefore add no extra weight.

Insulating your van is the foundation for a comfortable conversion. Whatever your project, good insulation will last you a long time.

FAQ about insulation for a converted van

What is the best insulation for a converted van?

The best insulation for a converted van is 3M Thinsulate, a synthetic hydrophobic microfiber insulation. It resists mold and moisture, two major problems inside a van. It provides both thermal insulation and acoustic absorption of mid and high frequencies. For complete insulation, it is combined with a butyl rubber sound-deadening material like DETOUR LAB, which handles low frequencies and vibrations.

How much does it cost to insulate a van?

The cost of insulating a van varies depending on several factors: the vehicle's length and height (a Sprinter 144 vs. 170 extended won't have the same requirements), the number of windows already installed (which reduce the surface area to insulate), the intended use (four seasons, winter trips, or summer use only), expectations for soundproofing and thermal performance, and the choice of finishing fabric (AEROTEX and ENDUREPEL Medley don't have the same price per square foot).

Can you insulate your van yourself?

Yes, insulating your van yourself is entirely doable, even without conversion experience. The process comes down to 4 steps: dampen vibrations with soundproofing material, add thermal insulation with Thinsulate, prepare the surface with a thin foam like Landau Foam, then cover everything with automotive finishing fabric. With the right materials and a little patience, it’s an accessible DIY project.

Do you need to cover 100% of the walls with soundproofing?

No, you don’t need to cover the entire surface with soundproofing material. Covering 25 to 30% of the total surface is enough to reduce resonance in the metal panels and eliminate vibrations. Butyl rubber is meant to stop vibrations at the source, not to create a thermal barrier—that’s the purpose of the Thinsulate applied over it.

What’s the difference between soundproofing and thermal insulation?

Soundproofing addresses vibrations and noise (road rumble, body resonance, low-frequency engine noise)—that’s the purpose of butyl rubber material like DETOUR LAB. Thermal insulation helps maintain the indoor temperature and protect against cold or heat—that’s the purpose of Thinsulate. For a comfortable 4-season van, you need both.

Does Thinsulate mold in a van?

No, Thinsulate does not mold. It is made of hydrophobic synthetic microfibers, which makes it resistant to mold and moisture. This is a major advantage in a van, where condensation and humidity can quickly become a problem—especially in winter in Quebec, because of the difference between the indoor heat and the outdoor cold.

Which van models can be insulated with these products?

Van d'ici insulation products are designed for the three main van models used in conversions: the Mercedes-Benz Sprinter, the Ford Transit and the Ram Promaster. Thinsulate is available in seven different sizes, pre-cut to fit each model, which greatly simplifies installation.

Does insulation add a lot of weight to the van?

No. The materials used (DETOUR LAB, Thinsulate, Landau Foam, ENDUREPEL and AEROTEX fabrics) were specially designed for automotive use and are as lightweight as possible. They meet automotive industry requirements and comply with the FMVSS 302 standard (fire resistance). Adding all these materials therefore does not significantly increase the vehicle's weight.

What temperatures can DETOUR LAB soundproofing material withstand?

DETOUR LAB soundproofing material withstands temperatures ranging from -20°C to +120°C, making it perfectly suited to Quebec winters and hot summers. Its three-layer composite structure (aluminum film, 2 mm butyl rubber, high-adhesion acrylic adhesive) ensures excellent durability over time, whatever the season.

Which finishing fabric should I choose for the interior of a van?

It all depends on the look and use you have in mind. ENDUREPEL Medley is available in 4 colors, stain-resistant, antibacterial, and easy to clean—ideal for a clean look and minimal maintenance. The tweed AEROTEX is available in 13 colors and has a water-repellent and stain-resistant treatment. Designed for heavy use, it's perfect if you're looking for more color variety and a textured finish. Both are durable and designed for automotive use.
