This is the first of a four-part series on environmentally-friendly insulation.
Most homeowners today realize that one of the biggest and best ways to lower their home’s heating and cooling expenses is with insulation. According to the U.S. Department of Energy, you can reduce heating and air conditioning costs by 30% if you install the proper insulation. But did you know that this can also be a significant way for your house to “go green”? There are a variety of environmentally friendly types of insulation on today’s market, available in a range of prices.
But before we discuss the ways your house’s heating and air conditioning can benefit from “green” insulation, we should talk about R-value. R-value is how insulation’s performance is measured. It tells you what the insulation’s resistance to heat flow is; the higher the R-value number, the better the product is at insulating. You need to choose insulation based on R-value, not its thickness.
The Department of Energy has a map recommending the R-value for insulation that should be used in new home construction here: http://energy.gov/energysaver/energy-saver
For the greater Cincinnati area, you can see they recommend an R-value of between R 38 to R 60 for attic insulation, to use just one example.
