Radiant Barriers Can Save Money On Air Conditioning While Still Providing A Comfortable Home

Fiberglass insulation is fast becoming outmoded thanks to the fact that it just doesn't work

, or work as well as other sorts of insulation. It's right that fiberglass insulation has been the most typical and reasonable kind of insulation for houses, office buildings and commercial facilities, there is however a new day dawning. There are now much better kinds of insulation on the market.

The more recent types of insulation receiving the most attention lately have been spray froth, blown in loose-fill and radiating barriers. Both these insulation work differently from each other and fiberglass. The insulative capabilities of spray froth and radiating barriers aren't rated on the same R-value scale because of the way in which they work.

Unlike fiberglass batting, which only slows the advance of heat passing through the glass fibers, spray foam insulation is a much more effective form of insulation. Because of the density of spray foam, the R-value, or resistance for heat transference, is much higher than any fiberglass insulation. Spray foam is one of the best materials for insulating a new home as it is being built.

If the home construction has been finished, then spray froth will generally not be a cost-effective technique of retroactively insulating a home. In this example, blown in insulation should be more cheap, but will continue to be work intensive.There's a comparatively affordable alternative.

Retrofitting a pre-existing building with a radiant barrier is usually more inexpensive than most other alternatives. There are different methods for installing a radiant barrier. The most common way is, in essence, to lay the barrier on top of ceiling joists in the attic. Radiant barriers can also be useful by installing under the home in a crawl space. With the reflective surfaces of the radiant barrier, heat from the exterior, which penetrates the roof, is reflected back away from the living quarters.

Radiant barriers have been used in several different applications. The technology is the same means which NASA uses for the astronauts in the space program by allowing the astronauts to retain warmth in the cold of space. While this radiant barrier technology has been in existence for over one hundred years, it was only recently adapted for the residential construction industry in the past couple of decades.

Mold and moisture always needs to be considered when installing a radiant barrier. Some applications may require the use of a perforated barrier for better condensation control. The professional installer in the local region should be able to determine the best way to install the barrier.
