Insulknop 5825

Indoor air free of toxins

Avoid possible contamination by chemicals.

The world is overrun with toxins. No one wants their haven on wheels to have any added chemicals off-gassing in a small living area.

Our wool is:

  • Boric Acid Freec acid free (this acid can cause chronic illness if you are repeatedly exposed to it
  • Petroleum Free
  • Formaldehyde free
  • Chemical additives free

Air Cleaner

We will always run into harmful chemicals at some point, but choosing an insulation that can render those chemicals down is a deal breaker (or maker)! Our wool fiber actually breaks down formaldehyde, reduces the risk of cancer, and fixes CO2, i.e. improves the air quality inside your van.

Prevent humidity and condensation

One of the worst things that can happen in a VAN is to have excess humidity. Insulknop 5825 has the natural ability to regulate the humidity by absorbing moisture when the air is damp and releasing it when it gets dry. It can absorb nearly 40% of its own weight in water and still feel dry to the touch. When the relative humidity drops below 65%, it will begin to slowly release that moisture back into the air. 

Insulate all shapes in your VAN’s cavities and gaps

and increase your insulation value.

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, and it will retain its thermal and acoustic value for 50 years.

Woolkop WL 5825

Not only has a high insulation value, the knop is specially designed to resist road vibrations, and also has the innate ability to:

– Absorb moisture from the environment.

– Act as an excellent sound insulator

– Keep the air free of odors

– Clean the air, Filtering and rendering down formaldehyde and other VOCs,

– Remain chemical-free

Among other things …!

Easy installation process


At WOOL LIFE, we value efficiency, sustainability, health and comfort. That’s why we designed our easy to install, high performance WL 5825 van insulation.

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.

The Mesh Fabric is included on all orders over 3 [150 ft boxes]

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 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

What else can Insulknop 5825 do?

(That other products cannot)

Natural sound absorbent

Four times more efficient than Roxul by reducing sound transmission and increasing sound absorption. Reduces stress caused by background and road noise, achieving a more comfortable and quiet environment.

Natural Fire Retardant

According to a study carried out by the Fire Service of England, people are 7 times more likely to die in a fire where synthetic products dominate as compared to those made of wool.

Most fire deaths are caused by highly toxic fumes or dripping from burning synthetics.

Our Insulknop 5825 requires 1230 degrees to ignite, without having to use boric acid as a retardant.


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.
