Owens Corning® Fiberglas™ insulation products are made using recycled content and renewable energy, and feature low VOC options, such as formaldehyde-free formulations, all to help you build more sustainably and earn valuable green building credits.

Blown-in insulation refers to the process of blowing insulation material (also known as loose fill) into walls and attics or around crevices using special equipment consisting of a tube or hose. Blown-in insulation materials can be made from cellulose, fiberglass fibers, or even styrofoam pellets.

While there are a variety of materials that can be used, including styrofoam pellets or loose fiberglass fibers, the most common material used for blow-in applications is cellulose material.

Keep the following safety tips in mind when working in your attic. Walk only on the ceiling rafters or joists. And not on the ceiling.

Owens Corning shingles are well known for their high quality because of the materials that are used and the process by which they are made. The shingles are layered with: Patented Fiberglas, which protects against the elements, and has a class A fire resistance rating.

Energy Efficiency Owens Corning has been a leader in insulation since we invented Fiberglas™ insulation 80 plus years ago. And we haven't stopped inventing it, evolving and innovating over time to ensure we're delivering you the best insulation options for today's homes.

Blown-in Insulation Fiberglass, cotton, and mineral wool can all work as loose-fill insulation material, but the far and away top choice for blown-in insulation is fiberglass.

The three most common types of blown-in insulation are loose-fill fiberglass, cellulose, and rock wool - each with its own pros and cons.

For attics, Webb recommends loose-fill, blown-in cellulose insulation made from recycled paper treated with flame-retardants and insecticides. “Cellulose insulation is generally less flammable than fiberglass insulation, and mice and other critters don't like to nest in cellulose,” he says.

More consistent temperatures: Attic insulation keeps conditioned air in the home, instead of allowing it to escape through your ceilings, which may make your rooms a more consistent temperature from ceiling to floor. This can make you more comfortable in your home, especially if you have cathedral ceilings.

Fiberglass, cotton, and mineral wool can all work as loose-fill insulation material, but the far and away top choice for blown-in insulation is fiberglass. Contrary to batts insulation, blown-in fiberglass insulation is perfect for filling in tight voids around wiring, pipes, or any area with awkward framing.

High Quality. Owens Corning shingles are well known for their high quality because of the materials that are used and the process by which they are made.

Class 4 rating Patented WeatherGuard® Technology helps Duration STORM® Shingles achieve a UL 2218 Class 4 rating, the highest rating for impact resistance, by integrating a polymeric backing material on the shingle.

The best types of home attic insulation are open cell spray foam, fiberglass, and cellulose. Cellulose is the oldest insulation material used for not only the attic but other areas of the home as well. Cellulose can be either a loose-fill or blown-in material and is primarily made of recycled newsprint or denim.

The Five Most Efficient Insulation Materials

• Fibreglass. Fibreglass is the most widely used insulating material these days.
• Cellulose. Cellulose is made from recycled paper products and isn't just an efficient insulator, it's very environmentally friendly.
• Mineral wool.
• Polystyrene.

Cellulose is generally cheaper than many other options. It can save you up to 25% more money compared to some of the standard insulations. Blown cellulose easily fills in cracks and crevices to provide a seamless barrier. There are less risk of fires, mold and insects.
