Facts About Attic Insulation

Before tackling attic insulation, it’s important to know how to safely access it. The first step is to secure an attic entry ladder. Use a work light or flashlight while climbing up. Lay two sheets of plywood along the perimeter of the attic. Then, hand up tools and supplies to your assistant. Before attempting the insulation, take a shower to remove any loose fibers and launder your work clothes after each use. navigate to this website

Attic insulation is necessary to ensure the comfort and energy efficiency of a home. In many cases, uneven temperature can cause discomfort in a home. Attic insulation protects the home from cold or hot weather. You can either tackle the job yourself on a weekend or hire a professional to do the job. Once you’ve gathered the necessary tools, the next step is to determine whether your home needs additional insulation. If so, make sure you choose the right type.

Another option for attic insulation is spray foam. It can be sprayed in the attic floor or into wall cavities, and is the most effective insulation available. It’s composed of a liquid polyurethane that expands when it makes contact with it. While spray foam is expensive and requires professional installation, it provides the greatest insulation. Spray foam insulation is a highly effective way to seal attic openings and reduce noise.

When choosing an attic insulation, make sure it has a good R-value. The higher the R-value, the more effective the insulation. Also, keep in mind that the amount of insulation you need depends on your climate, as hot climates will require R-30 insulation, while cold climates will benefit from R49 insulation. If your climate is mild, however, then you can settle for an R-value closer to 30. This way, your attic will stay warm and cozy for longer.

Blown-in insulation is another popular option. This type of insulation is a form of loose-fill insulation. It comes in sheets and blankets and is often made from plastic, fiberglass, mineral wool, and other materials. While it’s inexpensive, it doesn’t provide the same level of insulation as foam insulation. Some homeowners have a preference for loose-fill insulation because it doesn’t require any type of air barrier. They can also add loose-fill insulation to attics to control the risk of mold.

While cellulose and fiberglass insulation are widely available, they are not the best option. They generally have a lower R-Value and perform poorly in attics. Another option is cellulose, which generally comes from recycled paper or wood. Cellulose is often marketed as a green option, but it doesn’t pass a comprehensive “green” assessment. While cellulose does contain a small percentage of recycled material, it’s too low in R-Value to be considered a green product.

Another option is to install insulation in areas other than the attic. Unfinished attic spaces should be insulated between the floor joists and the rafters. The same rule applies to finished attics. A vapor barrier is necessary, but it’s not sufficient. For finished attics, the insulation should extend over the band joists, so that there’s a safe gap around the fixture. By extending the insulation to the joist space, it reduces air flow and heat.
