Old homes can be drafty, but they don’t have to be when you properly install home insulation. Before starting your project, be sure to visit a building supply company to learn more about the different types of home insulation. In this blog post, we will go over the areas in your home that can be insulated so you and your family can live in comfort this winter.

Unfinished Attics

Most homeowners and contractors choose loose-fill or batt insulation for attics. Attic insulation should be a certain thickness to keep your house warm in the winter and cool in the summer. For rock wool or fiberglass insulation, you’ll need 11 inches. Cellulose insulation will need a thickness of 8 inches. Since heat rises, it’s important you properly insulate your attic. In the winter, heat could be allowed to escape through the attic to bring a chill to your home.

Floor Joists

The floor joists are the wooden beams that act as structural supports for your floor. You’ll want to install home insulation in between floor joists to decrease airflow between the levels of your home. Since heat rises, it’s important to make sure floor joists are properly insulated so your home remains at a comfortable temperature year-round.

Exterior Walls

One of the easiest ways to insulate existing exterior walls is to cut a hole from the inside or outside of the home in order to access inside the wall. Insulation is then installed in exterior walls. You’ll need a licensed contractor to handle this, but the results are worth the cost of home insulation. Blow-in insulation is often used for existing walls because it is less invasive than other tactics.

Floors above Unheated Garages

Any floors above unheated spaces should be properly insulated to prevent heated or cooled air from escaping your home. If your home is constructed in a way that there is living space above the garage, you’ll need to make sure the above floor is insulated properly. Insulation products also prevent car exhaust and other air pollutants from breaching your living space. Make sure an air barrier is also installed to stop cold air in the garage from compromising subfloor insulation.


Your home should be insulated from the roof to the foundation to keep it comfortable year-round. Not only will a properly insulated foundation reduce heating costs in the winter, but it will also prevent humidity problems. When constructing new homes, contractors use insulating concrete blocks and other materials to offer both structural support and insulation. During new home construction, we recommend consulting with an experienced building supply company to find the right insulation products for your home.
