Azek PVC deck boards with Joist Tape?
TimberTech (i.e. AZEK Building Products itself) now offers a joist tape product PRO-Tac which is made with butyl with a PET liner and TPO backing. In addition to PRO-Tac there are other butyl products such as Trex Protect and Imus Seal, the latter claims to be compatible with a wide variety of deck boards from real wood to composites and PVC. Pricing through my local lumber yard for PRO-Tac was similar to Amazon pricing of Imus Seal.
