Q: How Much Butyl Tape Do I Need?

First you need to take a measurement to get the linear feet of your crawl space’s perimeter. For example, if you have a crawl space that is 50 feet long and 20 feet wide (1000 square feet) we simply add the measurements of each wall to get your total perimeter linear feet. 50 feet + 20 feet + 50 feet + 20 feet = 140 total linear feet. That’s how much butyl tape you’ll need. Since each roll is 50 feet, you would need 3 rolls! This will meet your 140 feet requirement, and give you some tape left over just in case you need it.
