Attic Insulation

Attic insulation can keep 85% of a home’s heat where it needs to be…in your home! Heat loss primarily happens straight up through the attic space when an attic is not properly insulated.

The amount of insulation a material provides is measured by its R-value. The higher the number in the R-value, the more effective the insulation is. Houses built before the 1970s probably have an R-value of 11 or less, but today’s standards call for R-values as high as 38 or more, depending on the home’s location.

Some homes may have gray material between the ceiling joists. If it’s an old house, that could be mineral wool. A newer house is likely to have blown-in cellulose. Either way, it can be left in place and insulation added on top of it.
