Wool Insulation for Campervan

Insulknop WL 5825

Specially designed for Vans

Higher ability to absorb road vibration.

Won't settle or slump.

Boric acid and petrochemical free.

Fills Places that Other Insulators Can Not Reach.


Whether you are choosing the nomadic lifestyle, or fulfilling that occasional wanderlust, having the right insulator will determine the long-term comfort of #vanlife. 

The worst thing that can (and does!) happen in van life is when your adventure is dampened by that first cold and rainy night, and you wake up a soggy-muff, in a thick-aired, condensation-filled van. Moisture is always a problem with conventional insulations and can get dangerous quickly, leading to mold problems. Modern insulations also have a laundry list of questionable and often downright toxic ingredients.

Insulation that contain petrochemicals:

Are dangerous, as they off-gas toxic fumes when the temperature rises inside the van in hot weather.

Some do not adapt correctly to the shape of the van and end up poorly insulated in several areas.

Lose their insulating power in cold weather, or when they get wet.

Never help to control humidity and condensation in your van.

Insulating all shapes in your VAN’s cavities and gaps

Wall cavities in vans are 2 inches on average, but in many areas they are deeper (up to 4.5 inches). Loose fill knops will completely fill those uneven cavities providing an even higher R-value.


Our patented manufacturing process makes a well-formed Wool Knop (insulknop 5825) that is completely resistant to road bumps and vibration.

Basically, it’s designed to put up with life on the road and all the bumps that come with it.

It doesn’t compress, settle, or slump like other insulations, which leave uninsulated areas over time, and it will retain its thermal and acoustic value for 50 years.

Not all wool insulations are created equal.

How is it installed?


Installing wool in your van is easy and efficient. In short, secure our fiber mesh to the studs of the van, then blow in the wool with a leaf blower! If that sounds crazy, we will gladly walk you through it and provide pictures and videos.

Don’t worry about about breathing boric acid or any other harmful chemicals (because there aren’t any), and you don’t even need to wear gloves when installing. Our wool is a blend of lambs’ and sheep’s that doesn’t itch. 

Once it’s installed in the walls, the wool will still grow by 20%, filling perfectly all the cavities even if they look uneven at first. Then it’s time to adventure!

How Much Wool You Need

Most vans have about a 2-inch cavity depth that you can fill with insulation. If you are securing the mesh right against the van’s metal framing, then a 2-inch covering will do nicely. If you are framing it out a bit with wood, then you can figure for a 2.23” to 2.7” coverage — this also will ensure that you have enough wool to fill gaps in the doors and other hard to reach places. Filling in those pockets will keep your van from sounding tinny and rattly and give you a solid, tight sound and feel.

Here is a chart to give you an idea of how much wool you will need.

If you have a van model that’s not on the chart,, use this formula to calculate how much you need:

[150 ft box] 1 box will cover 150 sq/ft at 1 inch thick

[450 ft box] 1 box will cover 450 sq/ft at 1 inch thick

Measure your walls, floor, and ceiling to get your square footage.

If you have 300 sq/ft in your van, and you didn’t add a lot of framing, you can go with 2 inches of insulation on average. You would need 300sq/ft x 2 inches = 600.

You will want to match that 600 as close as you can, so that would be 1 [450 ft box] and 1 [150 ft box], to fill all you need.

Add one box of mesh, this is enough to completely cover any model VAN

Then you’re good to go!

Enjoy your VAN for many years to come


We offer a 30 year warranty, even though some places like Buckingham Palace have maintained wool installed in good condition for over 200 years.

It is safe to say that the long-lasting performance of our insulation will far outlive the van it is installed in.

If you are not satisfied with the product you will get your money back with no questions asked.

What do our customers say?

“We started our van build and used the wool in all the places where we could. Before we could finish the installation we had to hit the road for a trip. We drove about 2000 miles with just the wool stuffed into the holes of our van and we were really impressed with how much it stayed in place. Now this was a completely ridiculous thing to do. We didn’t cover up the holes at all and we were just curious how it would work out. And to be honest it worked out way better than we thought. I actually have total faith in this product. And I’m glad that we went with this over the traditional bats.."
Alexei High
“We enjoyed the whole installation process, the feel of the natural wool and not having to use special equipment. I thought it would be a more difficult task to do but it only took a couple of days. We are delighted."
Scott & Steph
""I came across Wool Life when I was looking for chemical-free insulation. It feels so good and is so clean! I also love the sound absorption. I love this wool!”.
 "I thought that it was harder to install, but the process was easy, and it had incredible results in the VAN, filling cavities that were difficult to reach with other products. Highly recommended."
Gabriel & Mary


Initially, the installation of the knops is a little more laborious than the batt, but has several advantages over the batt that make the VAN more comfortable. The first one is that the cavities are completely filled (which means better insulation). The second one is that the knops will not settle with road vibration.

We do not sell batts at the moment, but will have them available in summer 2021.

Pesticides are used in sheep to control ticks. They last in the wool for a maximum of 8 weeks. Shearing of the sheep is not allowed for at least 12 weeks after the application of any pesticide, ensuring that there are no chemicals on the fiber.

Some people think that they are allergic to wool, but wool is a protein, just like our fingernails! The perception that wool can create allergies is not correct. The reason why some people have that perception is because they have had coarse wool clothing that is not suited for wearing in direct contact with the skin. Our wool is a special blend that does not belong to the itchy category, and is ideally suited to the products we manufacture.

Wool is washed with a non-ionic environmentally friendly detergent to clean it from any soil and grease that builds up during the period it grows on the free range sheep. No harmful chemicals need to be added.

When you compare the coverage at 2 inches thick, the higher R-Value knops are cheaper than wool batts. With loose fill, you can completely fill uneven wall cavities, and if you are framing it out and have a thicker area to fill, you may end up using more wool — but you’ll also get more insulation, acoustic value, moisture regulation, and comfort.
