INSULATION – FAQ’s

R-value is a measure of how well a layer of insulation (or any other two-dimensional barrier) resists the conducive flow of heat. Insulation manufacturers always print the R-values of their products on the labels or bags. Most of the time, R-values will be printed on the facings of fiberglass batts and rolls. Depending on where you live and the part of your home you’re insulating (walls, crawlspace, attic, etc.), you’ll need a different R-Value. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. See the Department of Energy’s (DOE) ranges for recommended levels of insulation below.
The installation of the insulation is the most important ingredient for performance. Regardless of the insulation type, the full R-value can only be achieved with proper installation.
Since R-values are cumulative, it’s usually not necessary to remove existing insulation when installing new insulation, unless your contractor deems it worthwhile or necessary.
The right R value, a measurement of the material’s ability to resist heat flow, and depth of insulation can help maintain temperature levels within your home. EnergyStar recommends that most attics should be insulated to R-38 or about 10 to 14 inches deep, depending on insulation type.
A great time to add attic insulation is when we are doing a reroof. It’s a simple process to take out a sheet of plywood to blow in the insulation while we are on the roof.
Why choose blow-in fiberglass insulation?
The attic is one of the easiest places to add insulation to improve the comfort and energy efficiency of your home. Johns Manville expanding Blown-In Insulation is designed for your attic insulation project in new or existing homes.
