Insulating systems are designed to control moisture, reduce the movement of heat, and assure proper ventilation. Among the most important home insulators is attic insulation. Whether you choose to add a barrier of foam insulation, fiberglass insulation, or a spray foam insulation, attic insulation will do wonders in helping control long term energy costs. The trick is knowing how much attic insulation you need and what material you should use, rather than whether or not you need it.
Do You Have Proper Attic Insulation?
If you or your attic insulation contractor are looking around and see minimal insulation, you might want to consider how much energy is being lost for little reason. Take a look. The first thing to do is head up those attic stairs, or up the attic ladder, and see what's up there. Do you see fiberglass strips between the rafters and joists? Is your attic finished, or are the rafters open and exposed? Is the ceiling finished or similarly open and exposed? Even if your attic does have insulation, what kind is it and how much is there? Equally important, does it look water damaged? If it does, it is causing more problems than it fixes?
Types of Insulation
The four most commonly used kinds of insulation are fiberglass batts (strips), blown-in loose fiberglass, foam strips, and spray foam.
No one of these is right for every home, which is why an attic insulation contractor is essential in determining how much and what kind you need. Otherwise you end up with excess moisture and stale air, or a drafty home. The most recent movement in insulation is the far more environmental-friendly cellulose insulation—recycled newspaper that is shredded, packed into strips and treated in fire retardant. Cellulose insulation easily rivals fiberglass and threatens to replace it.
Finding the Right Attic Insulation Contractor
Usually, without the help of an expert, you simply won't know how much insulation is enough. It's a difficult balance, which is why there is a construction specialty in insulation contracting. With the demands differing from climate to climate, and home to home, it is hard to know what is adequate when it comes to home insulation. If you are unsure, if you find your home to be drafty, or the air to be stuffy or stale, or if you notice mold in your attic or see spots on your ceiling and suspect it might be from moisture buildup, call a professional.
Attic insulation is one of those home maintenance tasks that is too often overlooked. But it contributes to the quality of your air, the price of your energy bills, your impact on the environment, and your own health and quality of life. If you suspect you might need more insulation, less, or a different kind, it is important to get a professional opinion. The difference will surprise you.
