What is insulation and how does it work:
Insulation is a product that that blocks this transfer of heat, helping to keep your home and office either cool or warm. It is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow and the higher the Rvalue, the greater the insulating effectiveness.
Heat flows naturally from a warmer to a cooler space. In the winter, this heat flow moves directly from all heated living spaces to adjacent unheated attics, garages, basements, and even to the outdoors. Heat flow can also move indirectly through interior ceilings, walls, and floors—wherever there is a difference in temperature. During the cooling season, heat flows from the outdoors to the interior of a house.You need insulation in your home to provide resistance to heat flow. The more heat flow resistance your insulation provides, the lower your heating and cooling costs.
Also, insulation can be used it as an excellent sound absorber, and when installed in walls and ceilings, can reduce the transmission of sound from other rooms or from the outside. Insulation products can also be used to reduce moisture transmission. For example, many fiberglass batts and blankets come equipped with a "facing" material that acts as a vapor retarder to help resist the movement of moisture vapor to cold surfaces where it can condense.
Where to Insulate in a Home:
For energy efficiency, your home should be properly insulated from the roof down to its foundation. This includes the following areas:
- Attic spaces
- Attic Access doors to unfinished attics
- Knee walls in finished attics
- Ducts in unconditioned spaces
- Cathedral ceilings
- Exterior walls
- Floors above unheated garages
- Crawl spaces
- Slab-on-grade floors

When and Why to insulate:
The decision is really up to you but below are some questions to ask yourself about your home when considering insulation:
Was your home build before the 1980's?
In a recent survey, only 20% of homes built before 1980 were well insulated.
Are uncomfortably cold in the winter or hot in the summer?
Adding insulation creates a more uniform temperature and increases comfort.
Do you pay excessive energy bills?
Insulating can reduce energy cost by as much as 33%.
Are bothered by noise from the outdoors?
Insulation helps to muffle sound.
Are concerned about the effect of energy use on the environment?
Insulation helps your home become more energy efficient.
Are you building a new house or an addition or install new siding or roofing?
Insulation can increase the value of your home and the quality of life for those within it.
