We are an Industry Leader in Van Insulation Technology


  • Condensation is inevitable, therefore moisture presents a serious challenge to long-term living.
  • Space is confined, this makes air quality an elevated consideration.
  • Vans can be loud; sound absorption is important.
  • Vapor barriers may pose significant risks.

Consider what happens to your indoor air quality when you insulate with subpar insulating materials – particularly when surrounded by exhaust fumes. Optimally, you should have a chemical-free passive filtration insulating material that manages moisture and reduces sound.

Van Insulation Material Comparisons

Thinsulate seems to be a common van insulator, but does it actually work? Thinsulate’s marginal insulating properties are outweighed by its acoustical deadening ability. Wool is an insulator, but also outperforms Thinsulate when it comes to acoustics and sound deadening.

Rigid Foam

Rigid foam is not ideal: it’s flat – your van’s walls are not. The rigid foam and the glue used to install it are petro-chemical based products that shouldn’t exist in your van. They are bad for your indoor air quality and for the environment. These materials also produce a squeaking sound while driving.

Don’t bother with fiberglass insulation. When inevitable moisture finds its way to the insulation layer, fiberglass will slump – reducing rvalue, and create an environment conducive to mold growth.

Ditch the Reflectix. It is only effective with a consistent air gap. This material actually acts as a vapor barrier and is better suited for covering the windows in your van.

Know What You’re Putting Behind Your Walls

Whether you’re doing a sprinter conversion or you’re working on a VW bus, moisture control should be your central consideration. Condensation will form on the inside walls. This moisture will find a way into your van’s wall space.

This means that you need an insulator which actively manages moisture.

Fiberglass insulation releases fibers into the air. This is the last thing you want to breath in your confined space. Do you know what kind of chemical binders are being used in your insulation? Additionally, when Fiberglass insulation gets wet it slumps and becomes a breeding ground for mold.

Rigid foam may seem like a viable solution, but consider first that your van’s walls are typically curved. This means that installation will require adhesion with a toxic glue. Beyond toxicity, this medium is known to squeak when the van is in motion.

Thinsulate, originally designed as a acoustic buffer, is yet another marginal insulating material. Wool insulation actually has better noise reduction coefficients.

Passive filtration, mold resistance, moisture management, sound deadening – does your insulation do this? It should – wool does.

We Take a “Farm to Wall” Approach When Insulating Your Van

At Havelock Wool, we connect nature to our daily lives through our all natural wool insulation. Our “farm to wall” approach to insulation is revolutionizing how others think about the insulation and building materials that go into their living spaces.

According to the EPA, your indoor air quality is 2-5 times worse inside your home than outside. Consider the building materials that contribute to your indoor air quality in such a confined space as a van.

Living a healthy lifestyle starts with surrounding yourself with wholesome foods and frequent exercise – what if you applied this same practice to home building and van insulation?

Frequently Asked Van Insulation Questions:

Can you use any wool?

Sure, any wool is better than no wool. But, our loose fill wool, for example, is mechanically processed to further allow for loft and higher R-values- called knops, providing a consistent product to our customers who trust us with their vans. Simply “chopping” wool into pieces after its sheared from the sheep has much less effective thermal properties.

Will the wool sag when I drive on bumpy roads?

No, in fact wool is constantly moving as it retains and expels moisture. This movement allows for a growing effect and it maintains its space. Wool also sticks to everything it touches.

Is wool good for road noise?

Yes! Wool has a 90 and 95 noise reduction coefficient.

What gear is needed to install wool?

All you need is a beer and a razor blade to cut open the packaging. No personal protection equipment required.
