Yesterday we talked about insulating the basement and the conversation was active, thanks everyone for joining in!
In yesterday’s blog we limited the conversation to the use of Polystyrene Rigid Foam panels. If you don’t know it by its real name (Polystyrene) then you probably know it as “Foam Boards” or “Foam panels.” These are typically pink or blue in color and they are used everywhere.
There are other uses for foam and today we are going to take a look at Spray Foam of which there are two major types. There is Open Cell Foam and Closed Cell Foam. We are talking only about Closed Cell Spray foam.
I came across a rather startling concept that states the vast majority, well into the 90’s of percent of homes where Closed Cell Spray Foam has been used will greatly outperform the “same house” that was insulated only with fiberglass.
Many times in the basement it is a great idea to spray the concrete walls of the foundation. The best is when that layer of spray foam goes up the concrete wall, closes off the band-joist of the house, and effectively seals the entire house to the foundation.
Something we talk about a lot at Vermont Modular is how important it is to Stop Cold Air Penetration. If there are places in the basement where cold air can enter it will. The very best way to close off all the cracks and crevices allowing cold air to penetrate the building envelope is the use of spray foam, Closed Cell Spray Foam. If you are successful in stopping Cold Air Penetration then your home will be far more comfortable and your Energy Costs will be dramatically less.
Heat Loss is the enemy along with Cold Air Penetration. The use of Closed Cell Spray Foam is an excellent product whether you live in Ira or Isle La Motte.
Advantages – spray foam seals all the cracks and crevices and therefore stops Cold Air Penetration!
Disadvantages – spray foam can be expensive, well actually it is expensive!
