The role attic insulation plays in your home

Making sure your attic is well insulated is a great way to save money on energy costs and to make your home more comfortable. The type of insulation you choose can make a big difference in how well your attic is insulated.

Attic insulation is designed to keep heat in your home in the winter and out of your home in the summer. Heat rises and, in the winter, any air that is heated by your furnace goes up û and out through your attic. In the summer, your roof becomes very hot and, with no place for the hot air to go, your attic can become the hottest space in your home. Without attic insulation, that heat would quickly get into your home.

One of the most important aspects of your home is attic insulation. The type of insulation you choose is also important because they are not all created equal and they don't all work with the same purposes in the same area.

Fiberglass batt insulation

Fiberglass batt insulation is probably the most popular type of insulation for attics. It is easily installed by homeowners and it fits perfectly between the joists of your ceiling. Installers need to be careful to make sure that the batts fit every crevice and corner snugly or a lot heat will get through the gaps. Moisture in your attic will reduce the degree of insulation you get from fiberglass batts. Any leaks, condensation problems or other sources of moisture must be fixed before installing batt insulation.

Loose-fill fiberglass insulation

Loose-fill fiberglass and cellulose is another popular type of insulation for attics. Spread by hand or with a blower, loose-fill insulation can be blown into corners and hard to reach areas, so there is less of a problem with gaps. However, moisture also damages the fiberglass and cellulose in loose fill and you need to fix any and all moisture problems before insulation installation.

Spray foam insulation

Spray foam is an increasingly popular type of insulation for attic applications. Not only does it get into hard to reach places, it expands to fill every gap and hole, so heat can't pass through spaces in the insulation. Spray foam is also waterproof and often, because it expands, it will stop small moisture leaks. Condensation isn't a problem because of how well spray foam seals your attic.

Other spray foam benefits include support for the structure of your house, fewer airborne pollution and irritants in your home, and less outside noise.

Insulation installation

While it might seem easy to install insulation, it might be a better idea to hire a pro. Let's be honest - no home project can be completed without some kind of debris or dust and insulation is one of the messiest. If you decide you don't want to take on a an insulation project by yourself and would rather hire a professional handyman for the job call us instead.
