In Construction They Keep Coming Out With Better Products To Make The Job Go Faster
The idea behind the Zip wall sheathing system is that the air barrier membrain is applied to the OSB sheathing in the factory and all you have to do is tape the joints. You have a wall that is water tight and air tight as soon as you stand up the walls. You don't have to go wrap the building later.
Zip claims about a 10% energy savings due to reduced air infiltration, making the insulation more efficient.
When used on the roof Zip can reduce radiant heat transfer by up te 97% thus reducing attic temperatures by up to 30 F thus reducing cooling costs in summer.
