If your house stays hot and doesn’t retain cool temperatures, this is due to a temperature regulation issue. Your attic space acts like an oven sitting directly above your head. Attics at peak summer can reach temperatures of 130 degrees, with only a thin layer of drywall separating you from this environment.

If your existing insulation is of poor quality, this would be an obvious starting point. However, fixing this problem is more about keeping the attic cool as a whole.  Strategically placed insulation can drastically lower the temperature of your attic.

Insulation on your attic floor will help slow the transfer of heat into the interior of the home, but this does not affect the temperature of the attic space. The sun beating down on your roof throughout the day is raising the temperature of your attic space. Per Title 24 New Building Code, the majority of engineering that we see today on our new construction projects calls for insulation to be installed within the roof rafters.

By doing this, you are stopping the heat from transferring through the roof before it enters the attic, drastically lowering the temperature of the “oven above your head.”

With the attic temperature significantly cooler, the home does not have to work as hard to keep the interior temperature regulated and maintained.
