The Efficient Wall Systems, or E-Wall, solutions makes for strong and tight buildings that go up quickly and are easy for trades to finish. This system is growing rapidly in Texas and Florida. A lot of builders here in North Carolina are now interested in E-Wall because it can save costs, reduce waste and deliver a better, tighter building. It's as practical for residential or commercial construction and can go up several floors in height.
The basic concept is a panel construction a bit like SIPs, but the walls are hollow to be filled with concrete on site, like ICFs. The fact that it's filled on site provides a tight monolithic structure which means you don't have to spend a lot of effort to seal gaps. The insulated panels provide for a finished wall with R14 or more. 10 of that comes from the 2" blue foam board, which can be doubled if needed for an R24+ wall.
Combine this shell with a spray foam insulated roof structure and you've got a tight well insulated house with minimal effort and at a very reasonable cost.
The building owner or resident can save 30% or more on energy costs. Plus, they can save on insurance because the structure is fortified. And there are savings in pest control because the monolithic concrete structure is pest resistant and termite proof.
