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! 

Should You Upgrade Your Attic Insulation in Summer? Yes! Here’s Why….

Many homeowners associate home insulation with winter months and cold weather. While insulation does keep your home warm during cold winter months, it also helps your home stay cool in the summer.  If you’re waiting until winter to upgrade your attic insulation, you’ll be wasting money on high energy bills all summer long.

Here’s why upgrading your attic insulation helps keep your home comfortable and your energy bills in line during the summer:

  • As the sun heats the surface of your roof, the air inside your attic begins to heat up.
  • The air inside your home is cooler than the hot air inside your attic. This hot attic air will try to move from the attic to your home’s living space, with the goal of creating an equal air balance between these two spaces.
  • Proper attic insulation combined with air sealing slows this process, keeping warm air in your attic and conditioned air in your living space. This means your cooling system will run less, your energy bills will be reduced and your home will be more comfortable.
  • BONUS! When winter arrives, your home will receive the same benefits during cold weather as it did during the hot summer months.

Any way you look at it, a home that lacks proper insulation and air sealing is less comfortable and less efficient than a home that is properly insulated and air sealed.

Not sure if your insulation is doing its job? Consider an energy audit. These are performed by specially trained staff and are geared toward getting you the biggest return for your home energy investment.

Why Upgrading Your Attic Insulation is More Cost Effective than Replacing Windows

White Piggy BankWhen considering home energy upgrades, many homeowners look at two projects: insulation or windows. There are many conflicting messages about which is the best investment for your energy dollar. The more visible upgrade option, windows come to mind as a top energy upgrade priority.
Before you open your checkbook, we invite you to read below to learn more so you can make the best choice for your home.
Building shell
When considering the total square footage of your home’s shell (i.e. the walls, floor and roof), windows comprise a small portion of it. Your house will benefit from upgrading your home’s attic insulation (and even exterior wall insulation) rather than investing in windows.
Heat flow
Air inside a home naturally flows from ground to sky. A home loses 70% of energy through the attic and roof – far more than is lost through windows or doors. Upgrading attic insulation keeps the air you’ve paid to heat in your home. AND don’t forget about air sealing! Sealing air leaks in an attic further prevents conditioned air from seeping out around construction penetration points found around ducts, attics and more.
R-value
R-value is a measure of the amount of heat flow a certain product resists. The higher the r-value, the better it reduces heat flow (a key component of energy efficiency). The r-value of windows can vary based on the number of panes, air space between panes, etc. Double pane windows have an r-value of 1.5 to 2. Upgrading attic insulation to current code results in an R-38. Combine this with the natural heat flow of the home, and it’s easy to see how a fresh blanket of insulation is a great investment.
Cost
When looking at bottom line, the choice is clear. According to Home Advisor the average cost to upgrade windows in the Kansas City area is $3,537. The same report shows the average cost to upgrade insulation in the Kansas City area is $1,139.
