In our recent discussions about insulation we mentioned that in vertical applications (exterior walls) we prefer to use Roxul “rock wool” insulation and in horizontal applications (the attic) we prefer sprayed in Cellulose. And on several occasions, we have walked away from sprayed in Foam.
In many ways we dislike spray foam not because it’s bad but only because it is so expensive and represents a “less than ideal” VALUE. One of the outstanding benefits of Cellulose is that it is relatively Inexpensive.
Several years ago, we featured a home that was insulated completely by using Spray Foam. It turned out that the manufacturer of the home miss-calculated the cost by many thousands of dollars. And, that company has since gone bankrupt, they did not charge enough for spray foam.
Take a look at today’s photograph and you will see a big space at the top of the foundation where Cold Air will Penetrate into the house. This in one of a few places where we strongly encourage you to use Spray Foam. The beauty of spray foam is that is expands upon application and fills every crack, crevice, and void; that effectively seals everything and Cold Air Penetration is stopped.
The use of Spray Foam in this type of application is a good value in that it does the very best job of closing off Cold Air Penetration. Since it is such a good product and you are using a very small amount the cost is relatively low. Hence it is a good value.
Vermont Modular goes out of its way to encourage Energy Efficiency but at the same time we have a sharp focus on Value.
Value is that thing that makes whatever we are talking about as something intrinsically desirable! If the cost is excessive then the desirability goes away quickly.
If we invest money to make our homes more Energy Efficient the pay-back time on our investment must be short and well worth the investment.
