Spray Foam ยป Why Insulate

Why Insulate

It's a good question. And in these days of soaring energy costs and uncertain supplies, there is an obvious answer. We believe you should harness the insulating power of foam insulation for use in your home. Not only is it a wise decision, but it is also practical to accomplish with a 21st Century state-of-the-art sprayed foam insulation called Spray Foam Insulation You already know how well foam insulates. Think about the effectiveness of some common foam products that we use on a regular basis:

The Foam Coffee Cup…Just 1/8" of Foam With An R-value Of Less Than One.

Go to your favorite fast food restaurant or 7-11 store and buy a cup of coffee. Hold the foam cup in one hand and pour yourself a cup of steaming hot coffee with the other hand. Go ahead…you won't burn your hand. The foam cup will only be warm to the touch. In fact, if the foam was a bit thicker, it is doubtful if you could feel whether the coffee was hot or cold. Only the steam would give it away. In this example, we think you'll agree that just 1/8" of foam is a pretty effective insulator.

The Foam Picnic Chest…Just 1/2" of Foam With An R-value Of Only About Two.

This is the classic example of the insulating power of foam and a great illustration of the importance of air sealing the area you want to heat or cool. Consider your experience with a foam picnic chest. You can learn a great deal about insulating your house from its' performance. You buy one at the local drug store or Wal-Mart for a couple of dollars, and you entrust it to keep your beverages cold for the weekend. Put in the drinks and a bag of ice on Saturday morning, and put the lid down tight, and it's pretty likely that you'll still have ice left on Sunday night. (Whether or not there are drinks left is another question!) You have just proved the insulating power of about a half inch of foam with a relatively low R-value (resistance to heat flow) of only about an R-2. (Frankly, if your house was as efficient as this foam picnic chest, you'd be ecstatic!)
