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!
