How do I measure for van insulation?

Keep it simple. Measure the area you plan to insulate (height and length) and take note of the average depth. Length X width= square footage. Each box of R7 is 100 sq ft at 2inches thick. Any overage is a good thing, coming up short is not. Every single van build of the same model is outfitted differently. Measuring is the only way to be accurate. We provide suggestions or averages as a guide only. Check out this video below for more detail on how to measure and overall installation technique.
