Proper attic insulation is a key element for a more comfortable and energy-efficient home. It is important to have a continuous boundary of insulation between the conditioned space and the unconditioned space. This boundary is referred to as the “Thermal Envelope” and consists of an air barrier that is adjacent to an insulation barrier. Any gaps, voids, or uneven areas can cause major deficiencies in the effectiveness of your home’s insulation.
Attic Insulation Homeowners today want to achieve great comfort and low energy bills at the same time. Not only will cellulose dry blow-in insulation in attics provide homeowners with a far greater ‘effective R-value’ than glass – it also virtually eliminates irritating, abrasive, airborne glass fiber particles. Many homes have inadequate insulation, some older homes have virtually none at all, and many attics in existing structures may be insulated with fiberglass that is doing a poor job — cellulose Insulation is the solution for all these problems. Apply Cellulose Over Fiberglass to add R-Value
Cellulose Insulation may easily be applied over existing insulation. *Research shows that capping fiberglass with more fiberglass “fails to restore the lost R-value” in winter conditions. Research also states that capping fiberglass insulation with cellulose insulation not only adds R-value, but it also restores the effective R-value that fiberglass insulation loses during cold weather. *Oak Ridge National Laboratories
Why is attic insulation important?
Heating and cooling accounts for approximately 50 percent of
your home’s energy usage. Inadequate insulation and air leakage are the leading cause of energy waste in most homes. Attics are often the easiest and most cost-effective place to insulate because most attics provide easy access for improvements. Attic insulation helps keep the home’s living space warm in the winter and cool in the summer.
What does attic insulation improve?
2) Enhances comfort inside the home
3) Reduces the size of heating and cooling equipment needed
4) Prevents condensation from occurring
5) Reduces gas/electric bills
How much attic insulation should I add?
Insulation levels are specified by R-Values that measure the
insulation’s ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate up to R-38 or about 10-14 inches, depending on insulation type.
How much money could I save?
Properly insulating your home can save up to 20% on your energy bills.
