What You'll Need

There are many types of insulation that can be bought when you are building a home or renovating an existing one, but two types stand out: board insulation and blanket insulation. As a homeowner, you have a responsibility to keep your home in shape and properly insulated so that it does not cost you more money than needed. The proper insulation will do this for you, but choosing between blanket insulation and board insulation isn't as easy as it sounds. There are many factors that go into the decision, which this article strives to answer for you.

Batt and Blanket Insulation

Many people confuse batt insulation with blanket insulation. Although they appear similar, they are, in fact, quite different. Batts are precut, which makes it difficult to work with, while blanket insulation is one continuous roll.

The flexibility of Blanket Insulation and Board Insulation

Since blanket insulation is formed into rolls and can be cut to the size you need it makes it incredibly easy to work with. Board insulation is rigid and comes in standard sizes to meet with building codes. Blanket insulation can be cut to any size you need in order to fill spaces around electrical boxes. You can also wrap ductwork and pipes with blanket insulation. Board insulation can be cut and placed in other areas but is best suited for walls and floors. It is not flexible and will break if you try to bend it too far.

Choices of Insulation

Blanket insulation and board insulation each offer many considerations as to what insulation would be best for your situation. Blanket insulation tends to have more green and recycled products than board insulation, so if green is your goal then blanket insulation may be the choice for you. Other than this slight difference, both insulation materials do approximately the same thing and can be combined to maximum effectiveness.

Hidden Area Insulation

Blanket insulation can be used in walls and floors but is best suited for walls. Board insulation can be used anywhere in the home. Certain kinds of board insulation, like the aluminum-backed board insulation, can be used in the attic or in the crawlspace of the home. These are the two places where heat and cold air escape and enter the home, which causes higher costs to run these utilities. Aluminum board insulation is a reflective product that reflects radiant heat, which is the primary cause of high cooling bills.

Cost of Insulation

Sometimes cost wins out over product effectiveness. This is usually the decision of a builder unless you have a direct hand in every choice. Blanket insulation tends to be more expensive than board insulation because the products and processes are usually more involved and costly. You have to pay extra money to be green and most blanket insulation is this type of product. Board insulation is easier to produce so it is cheaper, with the exception of polystyrene insulation. You can pay more money now to save a lot more in the future.
