Vapor Barriers

Measuring for vapor barrier:

1. Measure your perimeter walls. Most crawls will require 4’ rolls around the perimeter. Remember to leave a 3-6” space at the top of the wall for termite inspection, and 12” overlap for any seams. Tall crawls may need two 4’ widths or a 12’ width roll.
2. Measure your square footage. Remember you will want a 12” overlap for any seams. Order whatever combination of rolls you need. You may want a little extra for corrections and repairs.

* It is a good idea to make a sketch of your crawl space. This will help you in ordering both the correct size vapor barrier rolls and the tape you will need. Don’t forget to factor in piers, support walls and any other obstructions. A good plan will save you time and money. All rolls are shipped on a 4’ spool. The 12’ width is tri-folded and shipped on a 4’ spool for easier handling.
