How important is


insulation ?

Choosing the right insulation will influence the comfort of your van more than any other factor, and in all weathers.

Whether you are going to live in your van and adventure full time, or use it for those spur of the moment weekend getaways, your van needs to be a cozy haven, and the right insulation is key!

Choosing the right insulation will keep you comfortable in your van in extreme climate conditions, as opposed to having your adventure dampened after the first cold and rainy night.

Vans are compact, airtight spaces and being inside produces a lot of condensation and discomfort, having a natural moisture regulating material in your walls keeps you from waking up soggy and muggy.

The right insulation for a Van Has to:

There are so many types of insulation to choose from

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.

3Mesa de trabajo 1

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

Never help to control humidity and condensation in your van.

And this is where the healthy option comes in:

Using lamb’s wool as insulation! Although wool has been used for thousands of years as insulation in places with climates as extreme as Tibet, it had not been used as architectural insulation for RVS and VAN conversions until the scientific rediscovery of its unique properties.

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 …!

There are several companies that produce wool insulation and here the question arises:

Is all wool insulation the same?

The answer is NO!

3 main factors set our Woolblend WL 5825 apart




These factors combined add up to one desired outcome


Better insulation and higher ability to absorb road vibration

The scientific rediscovery of Wool’s unique properties

In 2009, using his scientific knowledge of over 40 years working with wool, Stephen Fookes, together with a group of scientists, developed a process that increases the insulating power of wool from R-3.5 to R-5.8.   That is an increase of 60.3%!!
Most vans have an average cavity depth of 2″. With other wool insulations, the best you can get is an insulation value of R-7 in that two inch space. With our pure wool knops, you will get an R-11.6.

What 's the result?

A more comfortable, all-weather van for a longer time. It is safe to say that our wool knops will outlast the life of your van. Wool in your walls will clean the air, manage moisture and reduce condensation, and dampen exterior noise.

How is this achieved?

Our Wool Insulknop WL 5825 is combed into small balls (or knops) in which the fiber is constantly trying to spread, i.e. the ball is trying to grow. Once installed, it will grow by 20%.

This guarantees that it will not settle or slump, keeping your van walls completely insulated (no gaps!) even with thousands of miles of road vibration. 

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

What else can Insulknop 5825 do?

(That other products cannot)

Minimize 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. 

Completely natural

Boric acid free (Boric acid can cause chronic illness with repeated exposure). Petroleum free, Formaldehyde free , Chemical additives free

Air Cleaner

Breaks down formaldehyde, reduces the risk of cancer and fixes CO2 improving the air quality inside the van.

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.

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 makes us different ?

We are probably the only company that has designed its product with a scientific understanding of wool fiber.

Since 1971, our founder, Stephen Fookes, has worked on the science side at places like the Commonwealth Scientific and Industrial Research Organization (CSIRO) in Australia and also the New Zealand Wool Testing Authority, of which he was director from 1976 to 2008.

He was involved in the improvement of wool manufacturing processes for thousands of products in over 27 countries, such as China, United Kingdom and many other countries in Europe, America and Asia. With the knowledge he gained in his field, he developed a line of products that use the attributes of wool with up to 60% increased thermal performance. Our Insulknop 5825 is among these products, and was presented officially at the bi-annual textile congress in Venice, in front of the world’s leading experts.
This is all very interesting, but you might wonder why it is relevant that our products are scientifically developed and that our process has an ISO 14001 quality control system. The answer is that you get a product that outperforms all other wool products and many synthetic ones. Our wool knops are incredibly valuable, but made affordable, and we are committed to delivering a quality, healthy insulation.

For your VAN to be:


and to have:


Now that you know everything about our natural wool insulation - Insulknop 5825

Take advantage of its benefits!

60% more insulation and real high performance: R value 5.825. Fill hard to reach cavities in your van’s panels. Our loose-fill wool insulation fills places that other insulators cannot reach. Fully breathable: 5825 is completely breathable and regulates the temperature and humidity inside small spaces, providing a fresh and safe living environment.

Absorbs carbon and purifies the air. A cleaner atmosphere equals a healthier environment.

No animal harm: it is produced according to the ITWO guidelines for wool sheep welfare. Animal welfare is a high focus in wool production. In addition to buying Insulknop 5825, you are taking care of the planet, since this product has a negative carbon footprint. The good news is that wool in any form reduces carbon in the atmosphere and, in some cases, sheep farming has been used to recover deserts into productive land.

How is it installed?

When you are ready to install wool in your VAN, you will want to install the mesh that will hold in all the knops. Then you will blow the wool in with a leaf blower. A simple leaf blower will ensure that the density of the wool is adequate. Besides, all the cavities will be perfectly filled and you will have the maximum insulation you can get all over your VAN.

There is no danger of breathing boric acid since it is boric acid free. Once you have installed it, the wool will still grow by 20%, filling perfectly all the cavities that may look uneven at first and, best of all, you will be ready to enjoy your miles of adventure in complete comfort.

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.

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!


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.
