What You Need to Know About Attic Insulation

When it comes to home insulation, the first area that comes to mind is the attic. Building airflow moves from ground to sky, naturally pulling conditioned indoor air up and out of a structure. Proper attic insulation helps keep conditioned air inside your home and helps keeps your home comfortable. Keeping conditioned air inside your home can also reduce wear and tear on your heating system and help keep energy bills in line.

There are three common methods used to insulate attics – blown-in fiberglass, blown-in fiberglass with air sealing, and spray foam insulation. Here’s what you need to know about each:

Blown-in Fiberglass

Insulating attics with blown-in fiberglass insulation is a quick and easy way to add R-value. This is a basic method of attic insulation and a cost-effective option to upgrade attics of existing homes or insulate attics in new homes.

Blown-in Fiberglass with Air Sealing

Combining blown-in fiberglass insulation with air sealing dramatically increases a home’s energy efficiency. This method helps keep conditioned air inside the home and adds R-value. In an existing home, attic insulation is removed and penetration points around the attic floor are sealed. After air sealing is complete, a fresh blanket of blown-in fiberglass insulation is installed. In a new home, penetration points around the attic floor are sealed before blown-in insulation is installed.

Spray Foam Insulation

Installing spray foam insulation in the attic of a new or existing home provides optimal energy protection. In an existing home, insulation is removed from the attic and spray foam is installed along the roofline. In a new home, spray foam insulation is installed along the roofline as part of the construction process.

Proper attic insulation combined with air sealing is one of the most cost-effective ways to save money on monthly energy bills. Wondering if your home could benefit from additional attic insulation? Ready to discuss insulation for your new home project? Contact our office today! 

Why You Should Air Seal, and How Spray Foam Can Help

Air sealing is the process of reducing the amount of air that leaks in and out of a home. It is an important step to reduce energy costs, reduce drafts and cold spots, help to keep out pests and allergens, and increase the overall air quality in your home.

Air leakage occurs when outside air enters and conditioned air leaves your house uncontrollably through cracks and openings. For years, it was believed that air leaks created proper home ventilation. Today’s building science proves this isn’t the case. Uncontrolled air leaks can cause too much or too little air to enter or leave the home. Either situation can result in poor indoor air quality.

Although air sealing is a very important part of home energy efficiency, it doesn’t eliminate the need for proper insulation. Foam insulation is a perfect solution to both insulate and seal air leaks.

Foam insulation expands when applied and completely fills a cavity. The product is applied as a liquid and expands to 100 times its volume. This means that the product fills cracks and crevices in a cavity, and expands to seal these gaps. With one application, your home is insulated and air sealed!
