It’s easy to install, suitable for DIY or professional projects, and works in all climates.

Works great if complete roll

Did my shop with this using 16in rolls. My third order of 50ft, came up short at 44ft so not able to complete, also have a slice thru a 4ft section so really only got about 35ft of usable. Will shop another brand due to this but if you get a good roll its good easy to work with stuff. Lays right between 2x4's. Also used one roll in RV to shore up underbelly heat loss. Updated review, seller refunded the full price due to issue with one roll. Will order again
