Best Time of Year to Insulate Your Home

Insulation helps your home retain heat in the winter and keep hot air out during the summer. Increasing insulation levels is a job that pays for itself by lowering your heating and cooling bills. Slower heat transfer between the interior and exterior also makes you feel more comfortable.

If your mind is on increasing home efficiency, you might be wondering: is now the best time of year to insulate?

Best Time of Year to Insulate

Traditionally, fall has been praised as the ideal season to add home insulation. It’s a mild time of year perfect for home improvements in anticipation of winter and keeping heating bills low.

However, in central and Southern California where winters are mild, spring may be the best time of year to insulate. After all, it costs more to cool your home in summer than to heat it in winter, so why not set your air conditioner up for success by increasing insulation in the spring?

Once installed, the insulation will work for many seasons to come, keeping the interior more comfortable and decreasing heating and air conditioning needs.

Where to Insulate

The attic is the most logical place to add insulation to an existing home, as it is a major source of energy loss in homes.

If you find you already have some attic insulation, it could be worthwhile to add more. One foot or more of insulation spread evenly across the floor is desirable for the most energy savings, but your local insulation company will be able to determine specifics and ensure you get the right solution.

You should also consider adding a radiant barrier before the summer. This is a type of reflective insulation that goes on the underside of the roof. It reflects heat back outside, helping the attic (and the rest of your home) stay cooler and more comfortable—and also more energy-efficient!

What Type of Insulation to Use

Fiberglass batts are often installed in attic floors and unfinished walls and ceilings. Other options include blown-in fiberglass, loose-fill cellulose and spray foam.
