ROTBLOC 2X JOIST PROTECTOR is just what its name implies, however it is truly a unique product that overcomes the issues of completing joist tapes currently on the market today (you know what they are). ROTBLOC 2X JOIST PROTECTOR relies on staples to secure it to the joist, not problematic adhesives. Not only can our 2X JOIST PRETECTOR be easily installed in ANY temperature or weather conditions, our 2X product does not require the lumber to be clean or dry like the competition. The 80 ft. compact roll and integrated drip edge (which sheds water completely off the joist) truly sets this product apart from the rest. If all of that wasn't unique enough, ROTBLOC 2X JOIST PROTECTOR is made from 100% recycled plastic and your purchase will help us get to 2,000,000 lbs. recycled plastic across all ROTBLOC LLC product offerings. Compare to joist tape.
