Attic Insulation

Statistics show that 85% of a home’s heat loss happens straight up through the attic space.

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 homes 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 over it.
