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 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.

Frequently Asked #Vanlife Insulation Questions

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.

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.

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

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