5 things you should know about insulation
Installing a new high-efficiency heating and cooling system is a great way to reduce your energy costs, but it’s far from the only solution.
Adding more or better insulation is a great way to reduce the energy escaping through your walls and ceilings. Here are some things to know about insulation.
What you need to know about insulation
R-Value: Insulation level are specified by R-Value. R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation.
Do you need more? Unless your home was specifically constructed for energy efficiency, adding insulation will probably pay for itself in just a few years.
Newer home tend to have more insulation that older homes, but there is still room for improvement. You can schedule a home energy assessment to get the full picture of how your home is using energy.
Blanket insulation: Blanket is the most common type of insulation, and it comes in batts or rolls. It’s commonly made from fiberglass.
Standard blankets and batts have an R-value between 2.9 and 3.8 per inch of thickness. High-performance (medium-density and high-density) fiberglass blankets and batts have R-values between 3.7 and 4.3 per inch of thickness.
Loose-fill insulation: Loose-fill insulation consists of small particles of fiber, foam, or other materials. They form an insulation material that can conform to any space without disturbing structures or finishes. This makes loose-fill insulation well suited for retrofits and locations where it would be difficult to install other types of insulation.
Foam insulation: Liquid foam insulation materials can be sprayed, foamed-in-place, injected, or poured. Some installations can have twice the R-value per inch of traditional batt insulation, and can fill even the smallest cavities, creating an effective air barrier.
