Information provided by Owens Corning.  For existing walls, there's no need to tear down and rebuild.  Simply have an insulation contractor seal them with loose-fill blown insulation. For new homes and remodeling, FOAMULARŪ rigid foam insulation is best for exterior walls.  It's the best for saving energy with its extra insulating power.  FOAMULAR insulation can be attached directly to the studs or over exterior plywood. Exterior walls are built using 2x6 studs or 2x4 studs.  Because the 2x6 studs give the wall more depth, it allows more insulation to be used.  If you have a specific R-value* you would like to use, you may use either of these two types:  5 1/2" thick R-21, or 6 1/4" R-19 fiber glass batt insulation.  However, condensing it into a 2x6 space will lower its R-value to R-18. 2x4 studded walls, have the options of R-15 or R-13, which are both 3-1/2 inches thick. *R-value is the measurement of resistance to heat flow.  The higher the R-value, the more the material absorbs heat, therefore slowing the transfer of heat through it.

For standard wall heights, you should use pre-cut batts rather than continuous rolls. Each piece of insulation is cut to the size of the most typical framing, which usually is built either 16 or 24 inches on center and about 92 inches high. These cut-to-size batts will make for a faster and easier job. 2. The insulation should fit snug and leave no space between the studs; top and bottom. If needed, cut the insulation around electrical boxes, plumbing and plumbing vent lines, etc., leaving as little space as possible.   3. When using kraft-faced batts with flanges, staple the flanges every 8 - 12 inches. The flanges can be stapled either to the front or inside of the stud, however, it's easier for drywall contractors if you staple the flanges on the inside of the studs. Note: Never leave faced insulation exposed. The facings on Kraft-and-foil-faced insulation is extremely flammable and must be installed in substantial contact with an approved ceiling, wall or construction material to help prevent the spread of fire in the wall, ceiling or floor cavities. Unfaced fiber glass is non-combustible. Other Related Links by The Contractors Solutions Online Network. Solar Panels and Energy - Broomall, PA.

The American Council for an Energy-Efficient Economy estimates are that about 10-35% of projected energy use can be saved cost-effectively by 2020.

The National Residential Energy Efficiency Database is an resource feature designed to help residential energy consumers save energy and money. Using the database, residential electric and natural gas customers can find out what programs their utilities offer, such as home energy audits, rebates for energy efficient appliances, and zero- or low-interest loans to upgrade insulation or replace old heating and cooling equipment. The extensive, regularly updated database lists residential energy efficiency programs offered by public and private utilities, rural electric cooperatives, and state agencies in all 50 states and the District of Columbia.
