There's no such thing as the perfect insulation. In fact, the variety of insulation materials used in houses and other structures proves that the "best" insulation really depends on a number of different factors, such as installation requirements, cost and moisture conditions.
But all insulation shares a common measuring unit known as R-value. The "R" stands for resistance to heat flow. A high R-value means greater resistance to heat flow and thus, greater insulating value.
To install insulation with a high r-value that will fit in your home, contact your local Dr. Energy Saver. Our experts will inspect your home and determine which choices are right for you!
R-value is used in different ways to describe insulation value. All types of insulation have an R-value per inch. For example, fiberglass batt insulation provides between R-3.14 per in. and R-4.3 per in. of insulating value. Spray foam insulation has a higher insulation value –around R-6 per in.
Insulation is also measured by total R-value. So a 3 ½-in.-thick fiberglass batt in a 2x4 wall cavity would provide total R-value of R-13 or so. The same stud cavity filled with spray foam insulation would have an R-value of R-21. When evaluating insulation levels in your home, a home energy analyst is also likely to include the R-value of different building materials to get the total R-value of a wall, floor or roof assembly.
In response to the increased cost of energy and increasing concerns about global climate change, the U.S. Dept. of Energy has established new recommended standards for building insulation. The general rule is that colder winter temperatures demand higher levels of insulation throughout the house. During a home energy audit or an insulation inspection, Dr. Energy Saver will compare your home's existing levels of insulation with those recommended by the DOE.
