First Floor Framing and ZIP System Sheathing
The right (bedroom and Merri's office) side of the first floor wall framing is done, and ZIP System sheathing has been applied. Left side is under way, with a pause for the weekend.
Here's an update video on the main floor wall framing progress.
With a little online research, I've learned of the interesting advantages of Advantech sub-floor panels and ZIP System wall and roofing panels. The ZIP System wall and roof panels come waterproof from the factory, and seams are sealed with special tape, on site, for air tightness, so there's no additional Tyvek wrapping required. They install in about 40% less time than typical plywood, felt, and water vapor barrier wrap.
The panels are compressed chips from wood that is SFI (Sustainable Forestry Initiative) Certified. They’re made by Huber Engineered Woods in Charlotte, NC, and offer many benefits—both in the construction process and in durability. Their manufacturing plant can produce about 65 truckloads of floor, wall, and roofing panels per day. The raw mat of wood chips is about 8" thick before being processed and compressed into3/4"-thick sheets. You might find this "how it’s made" video interesting.
