Image
Advanced framing details include framing aligned to allow for insulation at interior-exterior wall intersections.
Image
Image
Advanced framing details include open headers and reduced framing around windows and two-stud corners to allow more room for insulation in the wall cavities while reducing lumber costs.
Image
Image
Image
Advanced framing techniques including 2x6 walls spaced at 24 inches on center and ladder blocking at wall intersections allow more space for insulation in the wall cavities while open-web floor joists provide space between floors for ducting.
Image
After attaching netting to the 2x6 studs, workers fill the wall cavities with R-23 of blown fiberglass made from recycled bottles.
Image
After securing the inner coil, cover the draw band and the seam with a generous amount of mastic
Image
After setting precast concrete basement walls on an 8-inch bed of trap rock, this builder sprayed 2 inches of closed-cell spray foam directly onto the ground then laid piping for radiant floor heating before pouring the concrete floor slab.
Image
After spraying the 2x6 wall cavities with 2 inches (R-13) of closed-cell spray foam, the walls are covered with netting and an additional 3.5 inches of fiberglass (R-13) is blown in.
Image
Air leaking through the home's envelope wastes a lot of energy and increases energy costs.
