Depending on where you build, there are certain regulations you'll need to consider when building with a NanaWall system.

There are so many building codes to keep straight; it’ll make your head spin. Architects and builders know this reality better than anybody. One rule they need to follow is building energy codes, which grow stricter as environmentally-conscious states demand energy-efficient and healthy buildings.
