The Most Effective Attic Insulation: A Comprehensive Guide

If you're looking to make a positive impact on the environment, blown fiberglass is the best insulation option for your attic. It's made from recycled sand and glass, making it lightweight and flame resistant. But why should you choose blown fiberglass insulation? What are the benefits of this material? When it comes to insulating your attic, you should make sure that you choose a material that is safe and effective. Blown cellulose insulation is one of the best options on the market.

This type of insulation is made from recycled paper products, making it an environmentally friendly option. Each package of blown fiberglass insulation includes eight pieces, each measuring 4 feet by 2 feet. Using all eight pieces without cutting them covers a 64 square foot space with 8.25-inch thick insulation. This blanket insulation for attic is easy to cut and install, and the thick insulating material also helps reduce noise and vibration in your home.

Affordable and effective, natural cotton attic insulation from Frost King is 1 inch thick and measures 16 x 48 inches. Use one or more pieces of insulation on walls, roof, and attic floors, or cut or break smaller pieces of insulation to fill gaps around pipes, ducts, windows, and doors. With an R-value of R-19, Greenfiber cellulose blown insulation is a viable option for attics, side walls, and roofs. Whether you spray it or choose to blow it, this insulation is easy to apply over existing insulation or on its own, and reduces heating and cooling costs by 20 percent.

The most effective attic insulation is closed-cell spray foam. The spray foam will create an airtight seal and will not absorb water.

However, aerosol foam insulation is also the most expensive insulation method. Closed-cell spray foam generally has an R-value of between 5 and 7 per inch, so you'll need at least 5 inches thick if you're insulating an attic for the first time. Consult the Energy Star recommended home insulation R-value map before making a decision. Loose-fill fiberglass seems to dominate attic insulation in newly built homes and has an R-value of approximately 2.5 per inch.

Shredded and recycled cellulose paper with added boric acid for insect control and fire resistance offers a better attic insulation option than blocks. Poorly installed cellulose insulation can settle over time, leaving gaps and voids that reduce its effectiveness. Attic insulation can be constructed from a wide range of materials, including cellulose, fiberglass, mineral wool, liquid polyurethane, and polystyrene. This radiant insulation sheet for attics from US Energy Products is a solid option when combined with other insulating material such as a foam plate or an insulating blanket since the radiant sheet can reflect up to 97 percent of the radiant heat.

Insulating your attic is a great way to protect your home from extreme temperatures and moisture damage while reducing heating and cooling costs. If you check with the North American Insulation Manufacturers Association (NAIMA), they will assure you that fiberglass or mineral wool are definitely your best option for insulating the attic. Blow insulation refers to the blowing or spraying of insulation products into the cavities of walls, attics, and floors. Loose-filled fiberglass attic insulation still experiences convection but not as much as the old fiberglass it used to.

While this insulation is also one of the most affordable and easiest to install types, it's not as effective as spray foam insulation. The most effective way to insulate an attic does not always coincide with the most cost-effective way. There are several different types of attic insulation available including cellulose fiberglass mineral wool liquid polyurethane and polystyrene. Two of the most common types of blow insulation are fiberglass rock wool and cellulose which are applied to an attic with a blowing machine for easy and even distribution.

We investigated the most sought after attic insulation in their respective categories and discovered that the best options are determined by their type R-value materials ease of application and other special features included in select brands.
