All that green board you see on the outside of homes under construction is a relatively new product on the market called “Zip Wall”. Frankly, it’s a revolutionary product! It’s a structural wall sheathing with a rubberized coating that resists water penetration.
Builders are normally suspicious of new products because we’ve been left holding the bag when the product failed in the past but I really like the “Zip System”. Moisture is a big issue in Florida unlike many other parts of the US. Between our torrential rain and hurricanes it’s something that requires extra care when building a home.
First the “Zip” structural panels are installed then the seam sealing black tape is applied over panel seams. Together they provide moisture protection and an air infiltration barrier. The “Zip System” eliminates the need for house wrap so tar paper backed stucco lath can be applied directly to the structural panel. What I really like is the rubberized coating on the “Zip” sheathing as it self seals as the wire lath staples are applied to the house. This is a feature house wrap was never able to provide. Additionally, the manufacturer backs their product with a 30 year warranty.
