Existing Home Insulation

Your home is an investment and improving your attic insulation is a great way to help protect that investment. Updating or adding to your existing home insulation is probably not something you think about often, at least not until you suspect you might need insulation services. The professionals at Millers understand that attic insulation isn’t the home improvement project that is going to be the most familiar to you and are happy to walk you through the entire process.

Millers offers an energy check and insulation assessment so that you can be confident that the energy improvements made to your home will come with a significant payoff in the years to come. Adding insulation to your home is an energy-efficient home improvement option that will not only create a more comfortable living space for you and your family, but it will save you money in your heating and cooling costs, essentially paying for itself over a few short years.

When is it time to think about insulation?

If you are noticing uneven temperatures between rooms, cold or warm walls and ceilings, drafty rooms, abnormally high energy bills, or are experiencing problems with ice damming in the winter; it is probably time to consider insulating your home.

If you’ve noticed any of the above-mentioned problems and have safe access to your attic, you can check the insulation levels on your own to determine the depth and uniformity of the existing insulation. As a general rule, if you can see the floor joists through the insulation, your insulation is not deep enough to effectively insulate your home.

If you are not comfortable checking your own attic insulation levels or would simply rather have the advice of an industry expert, contact Millers for a free insulation and energy assessment.

Air Sealing

What are Air Leaks

Air leakage can be a major contributor to high energy costs and uncomfortable living spaces. This occurs when outside air enters your home and the heated or cooled air leaves. Air leakage is not the same as ventilation and should not be thought of as the same. Air leakage is an uncontrolled air exchange. Uncontrolled air leaks are one of the leading signs your home needs winterization and can cause poor indoor air quality, moisture problems, and potential health issues for the home’s occupants if not addressed properly.

Detecting Air Leaks

The first step to addressing air leaks and drafts is to detect exactly where your home is experiencing leakage. Many drafts are easy to find because they are easy to feel, such as around windows and doors. Less obvious yet still common leakage areas, such as holes hidden in your attic, basement or crawl spaces are more difficult and take professionals to locate.

When air sealing is combined with added insulation, your home will be more comfortable and have lower energy bills during the hottest and coldest times of the year.

In this video, we are performing an air seal. Our team is sealing all penetrations from the attic into the home in order to keep cool air in the home and out of the attic. (This idea is reversed in winter.) After completing the air seal, we then add the DOE’s recommended level of insulation for a southern climate.

Attic Insulation

Very low level insulation

Most homes, especially older homes, do not have sufficient attic insulation to be energy efficient. Adding insulation to your attic can be the most cost-effective way to improve your home’s energy efficiency. A quick and easy test to see if you have sufficient attic insulation is to look for the floor joists in the attic. If you can see the floor joists, you probably could benefit from more attic insulation. Your local insulation professionals will be able to inspect your current attic conditions and be able to tell you what R-value (for insulating power) is right for your home.

Radiant Barrier

A radiant barrier is specifically designed to help keep your home cool on the hottest days of the summer. It works by reflecting heat away from the interior of your home to keep the space cool. This is an affordable energy saving option that can be applied along with insulation to better improve the insulation performance. With the application of Radiant Barrier, you will feel cooler and more comfortable in the summer months while cutting cooling energy costs in comparison to past years. A radiant barrier from Millers will:

  • Block over 80% of the sun’s heat from your home
  • Improves the performance of your insulation
  • Substantially lowers your cooling bills
  • Keeps your home in the shade
  • You feel cooler, more comfortable
