| Materials | 100% Natural Sheep’s and Lamb’s wool from the rolling hills and IWTO Certified Farms of New Zealand. All wool is treated with something to deter insects at the scouring stage, whether it is going to be a garment, bedding, etc. We have control of our whole process, so we treat the wool with a very small amount (0.25%) of a non toxic insect repellant called Eulan SPA. This is applied to the wool as a liquid detergent at the final scouring stage, and is absorbed into the inner core of the wool fiber. Eulan SPA was developed specifically for use with wool products, and protects the wool from damage caused by moths and carpet beetles. We do not use ANY Boric Acid, because of the negative health effects associated with it. Companies that treat with boric acid usually treat with a very high level, 8% by weight (1% by volume). |
| Safety | Because of small fibers, the use of dust masks is recommended when blowing in the loose fill wool. No gloves are necessary. |
| Color | The color of the wool may vary slightly. |
How Many Boxes of Loose Fill 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 (includes the floor and ceiling)

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!
We have excellent news for you!

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!
