Do you ever find that the temperature in your house does not feel the same in every room? Is your heating or cooling bill much higher than you would like? Does your roof usually end up with an ice dam in the winter time? Are some walls in your house very cold or hot? If so, this may be a result of poor insulation in your home. Insulation in the attic helps maintain the right temperature in your house and is also energy/cost efficient. To keep warm in the winter, cold in the summer, and to decrease your bills, follow these instructions on how to insulate your attic.
Before starting the project, be sure to have all proper materials and safety equipment. Also, be sure to not move any vermiculite insulation if that is what is in your attic. If so, you cannot begin this project until it is verified that that vermiculite does not contain asbestos. For more info on how to spot vermiculite, click here.
The Key Ingredient
Though there are several kinds of insulation, here are a few that get the job done.
The first and easiest kind to use is roll-on or blanket-type insulation. These are fiberglass batts that fit between typical attic framing. If your attic already has insulation, you do not have to use the same kind that is already there. This insulation comes in rolls and roll out perpendicular to the joists in the attic.
Next is loose-fill or blown-in insulation. Even if you want to do the project yourself, this usually requires the help of a contractor. A machine shoots the insulation over the attic floor framing and can reach crevices that roll-out insulation may not reach. You can use loose-fill on already laid out rolls of insulation and vice-versa.
If you plan on turning your attic into a finished room, you are going to want to go with sprayed foam polyurethane. In this case, you will insulate the ceiling of the attic, not the floor. The foam will mold to rafters and block water vapor out. Though it is more expensive than other types of insulation, it is very effective.
An important thing to remember is to never put insulation too close to vents or fixtures. You want to avoid any fire hazards by using sheet metal or wire mesh that guard those fixtures and vents.
