Zip R-3 - $40, R-6 - $50, R-9 - $60, R-12 - $70. I needed just over 100 sheets, so I spent $3,000 extra on sheathing, but that comes up to only about $300 more total compared to buying separate sheets of rigid insulation board.

Mar 11, 2019 · The layer beneath the siding—the water-resistive barrier, or WRB—is what will protect the plywood or oriented strand board (OSB) sheathing from any water that sneaks in. Many builders have turned to Huber’s Zip System sheathing, a type of OSB with a coating of resin-impregnated kraft paper. It’s designed to be water resistant but vapor ...
Stressed out. 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.
Clarification of use over sheathing membranes, air and vapour barriers Tape identification The CCMC currently publishes 4 Evaluation Reports (CCMC 11362-R, 11955-R, 13401-R and 14018-R) for pressure-sensitive tapes used over sheathing membranes, air and vapour barrier material (MasterFormat 07 25 20). The evaluated tapes are
ABAA has set a maximum air leakage rate for wall air barrier assemblies as being 0.04 CFM/ft 2 at a pressure difference of 1.57 lb./ft 2 [0.20 L/(s·m 2) at a pressure difference of 75 Pa] when tested in accordance with ASTM E 2357 Standard Test Method for Determining Air Leakage of Air Barrier Assemblies.
unfaced fiberglass batt insulation (approximately R 19). The vapor barrier is the interior face of the exterior impermeable insulating sheathing. If the wall assembly total thermal resis-tance is R 29 (R 19 plus R 10), the location of the vapor barrier is 66% of the way (thermally) towards the exterior (19/29 = 0.66).
Adding one inch of insulating sheathing (R-5) will increase a 2’ x 6’ stud wall from an effective R-14.4 to an effective R-19.4. This represents an increase of 35 percent effective thermal resistance, with only 15 percent increase in the overall wall thickness.
Mar 21, 2016 · There’s another path, as well: all-in-one structural sheathing with an integrated weather barrier. Introduced by Huber Engineered Woods, the ZIP System consists of structural panels with a factory-applied membrane and a high-performance tape for the seams. (It resists liquid water, but it’s vapor permeable, the manufacturer says.)
