Week of August 20, 2007: Alphonso explains the value of board insulation to Gianluca. The exterior wall will consist of the rigid insulation on the exterior side of the metal studs, house wrap, wood furring strips and then the cedar siding. There will also be vertical stainless steel channels every 6' feet that work with the design module and frame the windows.
Inside, there will be open cell foam insulation between the studs and then drywall. Select interior walls will have recycled newsprint insulation between the studs for sound insulation.
