At the Cobb Hill co-housing community, Bob and general contractor Mark Albee look at some of the energy efficient and eco-friendly products in use.
The home’s large south-facing windows provide significant passive solar gain. They are Thermotech pultruded fiberglass windows from Canada and have Styrofoam insulation in them.
For cost reasons Mark is using Thermotech’s double glazed window with one low-e coating. Because the glass and fiberglass have a similar expansion coefficient you get a window that is tight through all seasons.
The flooring is yellow birch from a mill in Maine. It’s a certified sustainable product that is made from short pieces that would ordinarily be discarded.
