Don’t Hesitate, Insulate and Ventilate

Chelsea O'Donnell

I have to admit that I’m a big fan of the winter. I love skiing, playing ice hockey and hiking in the snow, but what I don’t love is coming home to a cold house. It’s around this time of year when I start to get calls from people all over town wondering why their home is so drafty and freezing when they’re paying a fortune in heating bills. The answer to their question is almost always a lack of insulation. Unfortunately, over 75% of houses in our area are under-insulated which means that heat is quite literally going through the roof.

Insulation is a cotton-looking fiberglass material bundled in pink or yellow colored rolls that you may have seen in your attic or behind the wall of new construction. It also comes in what we call “loose fill” which can be blown into harder to reach areas. Contractors use insulation between walls, in attics and in basements to retain heat in the house in the winter and keep the heat from getting into the house in the summer. The amount of insulation needed for a home is measured by its R-Value, which equates to its resistance to heat moving through it. Simply put, the higher the R-Value, the better the insulating properties.

Back 50 years ago when many of the homes in Central Connecticut areas were built, R-Value wasn’t a popular unit of measurement. Instead, they kept it simple and measured insulation by its thickness in inches. When a home was constructed, the contractor would put about three inches of insulation into the attic, if any was used at all. Three inches of insulation would give that homeowner an R-Value of about R-10. According to EnergyStar, homes in our area should be fitted with insulation that measures between R-49 and R-60. So if you have a home from the 50’s or 60’s and have never done an upgrade to your insulation, your home is definitely not equipped to handle our harsh Connecticut winters.

If you’re one of those homeowners scratching your head, trying to figure out why the house is so cold, take a trip up into the attic. Chances are your insulation isn’t up to scratch and it’s probably time for an upgrade. As a general guideline, insulation with an R-Value of between R-49 and R-60 will sit at between 19 and 22 inches thick when settled. How does your insulation stack up to that? If it doesn’t, you don’t have to worry - insulation is easy and inexpensive to install and has one of the highest resale values of any home improvement job going.

With any proper insulation job also comes ventilation, which allows air to move through the attic, preventing over and under heating and reducing the risk of mold buildup. We will talk about that in detail next week.
