How Attic Insulation Works

 

We’ve talked a lot about radiant barrier lately, and what it does. Today let’s talk about insulation.

The Purpose of Attic Insulation

The concept of insulation is to help your house hold temperature longer. Your refrigerator is insulated to help it stay cool. Your oven is insulated to help it stay hot. Insulation can be anything that will help you hold temperature by reducing the escape of heated and cooled air.

What To Look For In Your Attic

By doing a simple attic inspection, you’ll be able to see what your average insulation levels may be. Most homes have extremely inconsistent levels of insulation: in some places, you'll see mounds of insulation, and in places, you may see the framing of your ceiling joists. Often those ceiling joists are about 6 inches tall, so in the areas where your insulation is not covering the rafters, you might have less than 6 inches of insulation there!

The recent changes in the energy code in Texas call for an R-38, which is about 14 inches of fiberglass insulation. In fact, the Department of Energy for the State of Texas recommends that you have between 14 and 21 inches of insulation!

What To Do If You Don't Have Enough Attic Insulation

If you see uneven or shallow spots of insulation in your attic, or if you think you don’t have at least 14 inches of insulation, give us a call. We’ll take a look at your insulation and tell you how much you have and what kind of shape it’s in. If you need an update to bring you up to the current code we can even top off your current insulation! Proper consistency across your entire attic will help your house hold temperature longer and save you thousands on your energy consumption!
