Do I Need Attic Insulation?

Great Question! Some of you may be reading this because you popped your head up in your attic and saw a bunch of pink or white fluffy stuff lying all over the place, or if you’re really unlucky saw nothing up there at all! If you are living in a home built pre-90s, chances are high that you do need insulation, but let me cover a few things to help you understand why. Starting with a question:

What is Insulation?

The short answer is: your home’s best defense against outside temperatures infiltrating your home. Basically, it helps keep the hot air out and cool air in during the summer, and vice versa (hot air in / cold air out) in the winter. We made a 5-minute video for you visual learners out there. Otherwise, let’s push on!

Cold air always moves to warmer air. Keeping this in mind, let’s do a drill. Envision yourself sitting on the couch during the summer watching your neighbor mow his lawn while he waters his grass with his own sweat (sorry for the visual) as your A/C pumps down cool air on you. Suddenly, the A/C turns off and you immediately can feel your house warming up. Next thing you know, beads of sweat start to form on your forehead and you might be questioning the usefulness of your A/C.

Does this sound familiar? If so, there is a good chance this is because your home is poorly insulated. Sure, there could be other factors at play here, such as a leaky house, or excessive exposure to direct sunlight (We cover some of these other factors in our post about keeping your house cool); but if I were a betting man, I would go with poor insulation.

Take a look at the left-side of this picture. Without sufficient insulation the cold air quickly warms up and wants to join the hot air outside. Because there is insufficient insulation, the cold air effortlessly radiates through your ceiling which is being cooked by heat trapped in that oven you call an attic and the cool air in your home quickly becomes hot air.

Now, take a look at this house: By adding proper insulation, you add a layer of defense to your escaping cold air. This is a big deal because now that heat in your attic cannot as easily heat up your ceiling resulting in your inside air staying cooler longer. Not only does this help keep your home at a comfortable temperature for you to continue laughing at your neighbor, but it also helps your A/C run less. So a win-win, right? Actually, it’s a win-win-win:

  1. Your air stays cooler longer
  2. Your A/C runs less, increasing its life expectancy
  3. An A/C that runs less means a lower energy bill

Make sense?
