Zip System by Huber Engineered Woods takes construction to the next level. Wall and roof sheathing (panels) are resin coated for maximum air and water resistance and have a high R-value (thermal resistance value). That means low heat loss and a very energy efficient product. The panels install quickly and joints are sealed with Zip flashing tape — that's it. The system is designed to eliminate the need for house wraps or roofing felt. Take a look at the picture at the left – you can what it looks like up close. The sheathing is an OSB (oriented strand board), coated with a water resistant, threaded resin layer. The panels are pre-marked with a fastening guide for error-free installation. Roof sheathing is red and wall sheathing is green, just in case you've somehow overlooked the large, black lettered warnings "Wall Use Only" and "Roof Use Only" stamped all over each panel.
The Zip Tape (a flexible flashing tape) is about 3 ½” wide and seals the joints between panels. It’s been put through some pretty rigorous testing to ensure it’ll hold up to even the most extreme environmental conditions, hence the 30-year warranty on tape and panels. But… here’s the real beauty of Zip System: Not only does it provide a solution to how to keep the interior of the structure dry during the framing process (a huge plus, especially in the case of additions), but it allows you to side, shingle, or apply whichever building product you’re using directly over it. The Zip System eliminates the need for house wraps and felt. (Not to mention the oh-so-effective use of giant plastic tarps duct taped and nailed over the build-in-progress.)
With that said, I know of at least one prominent builder in my area who still insists on using Tyvek over the Zip System as a super back-up measure – I may have previously mentioned the wind we get around here – even though Huber makes panels specifically for high wind zones.

Tricks to Proper Installation
There are a few tricks to proper installation, a big one being that the nails should NOT be sunk into the panel, but rather should be flush with the surface. (My better half can attest to this. He and his partner weren’t so careful about this particular detail and ended up with some minor water seepage.) Here is a more comprehensive read for installation tips.
