Not so fast.
Despite claims, ZIP System® didn't install 40% faster than Tyvek® HomeWrap®. The truth was closer to 0.25%. And some installation stages took much longer than Tyvek®.
Panels must be installed before taping
Tape requires careful centering
Taping corners requires extra time
A fastener too far.
Installing ZIP System® coated sheathing comes with the risk of over-driven fasteners, each of which creates an entry point for water over the life of the structure. With Tyvek® HomeWrap®, flanged fasteners prevent over-penetration.
Conventional nails can over-penetrate sheathing
Coated sheathing is easily damaged by nails
Each over-driven fastener creates an entry point for water
Gaps, wrinkles and fish mouths.
A typical ZIP System® installation requires a quarter-mile of taped seams that can funnel water into the wall system. Tyvek® HomeWrap® only needs taping where sections overlap.
Typical install has a quarter-mile of taped seams
Taped seams are not shingled
Any gaps, wrinkles and fish mouths allow water to enter the wall
ZIP System® tape is prone to stress and tears at inside corners, creating yet another place for air and water to get into the wall. Tyvek® HomeWrap® folds easily into corners—forming a continuous barrier against air and water infiltration.
Requires careful application to get tape tight against corners
Cladding can put stress on improperly applied tape
Tape is prone to breakage
