Green Building Insulation
Green Insulator Resource
Sustainable building starts with reducing the heating and cooling loads of the home as much as possible and insulation is the key to energy conservation, a cornerstone of green building. Well-insulated houses not only save energy, thus lowering operating costs, but also keep people more comfortable.
See Chapter 11 on Insulation in the Green from the Ground Up book for more details or contact us about training .Appropriate Type and Amount of Insulation
Because different types of insulation have different insulating values (R-values), what you choose determines how the house is framed and detailed on the outside. Your exact route will probably take a variety of factors into account:the appropriate level of insulation for the region where you build. See a the climate zones around the country and their recommended insulation levels in Chapter 11 on Insulation in the Green from the Ground Up book for more details. your experience with alternative building practices the availability of different kinds of insulation how much experience your insulation contractor has the design of the house local cost comparisons for different types of insulation Green Insulator's Transition Guide
Conduct a Home energy audit, how much insulation is there?An audit will indicate how a house is performing and where it is loosing heat. A blower door test and infrared camera will outline the problem areas. Contact a licensed HERS energy auditor in your area, or look into become certified yourself
Seal all wall penetrations such as wires or pipes or electrical outletsEven a small air leak can have a huge impact on heat loss over the life of the building Use expansion foam Canned expansion foam. Look for products that use HFC rather than HCFC or CFC as propellants.
Add additional insulation to the atticAn attic is a great place to pile on the insulation. A large quantity of a home’s heat is lost through the attic Lay R-38 batts perpendicular to each other or blow at least 10 inches of cellulose in most climates. Use insulation with 75% recycled content and doesn't emit formaldehyde or other VOC’s. loose fill cellulose, fiberglass or spray urethane foam.
Remove window trim and seal around windowsIncorrectly installed windows are a major source of air infiltration. Remove window trim and drywall from the inside or exterior trim to expose the window framing. Insulate any cavities between the frame and studs. Canned expansion foam. Look for products that use HFC rather than HCFC or CFC as propellants. Choose foam designed for windows so that the pressure from the foam doesn't warp the windows.
Insulate the crawl space and between floor joistsThe crawl space helps compose a significant part of the thermal envelope. It should be insulated to prevent heat loss in the home and to keep feet warmer in winter. Install batt insulation between joists to at least R=19 or higher depending on climate. Rig...
