What Type of Materials are Used for Attic Insulation Installation Service?

When it comes to attic insulation installation service, the most common materials used are cellulose, fiberglass, and mineral wool (rock or slag). All of these materials are made from recycled scrap materials. Cellulose is mainly composed of recycled newsprint, while most fiberglass products contain between 40 and 60% recycled glass.

Boric acid and other substances are applied to protect the flame-proof attic insulation.

Another material that can be used is cellulose, which is made from different recycled materials such as wood, newspapers, and cardboard.

Cellulose follows the same distribution method as other types of insulation, but it is composed of shredded and recycled cellulose paper with added boric acid for insect control and fire resistance. Loose-filled fiberglass has an R-value of approximately 2.5 per inch and is the most common type of attic insulation in newly built homes. However, the most effective way to insulate an attic does not always coincide with the most cost-effective way. In 1991, Oak Ridge Laboratories published a study that revealed that loosely filled fiberglass insulation material for attics lost much of its insulating value when temperatures dropped below 20 degrees.

This makes it an inferior product compared to cellulose. If you feel a noticeable drop in temperature soon after you turn off the heating, you may have a problem with the attic's insulation (or lack of it). When properly installed, both types of insulation fill every nook and cranny of a space and form a perfect air barrier. Fiberglass insulation for loosely filled attics still experiences convection, but not as much as old fiberglass used to have.

So, if the attic isn't well insulated, it escapes, which means you could also be throwing money down the roof. If you check with the Cellulose Insulation Manufacturers Association, they will assure you that cellulose is definitely your best choice for insulation. Then, once you've finished reading, you'll be able to evaluate what the best attic insulation is for you and your family. Unlike all other types of attic insulation, spray foam insulation is the only one that comes in liquid form.

If you check with the North American Insulation Manufacturers Association, they will assure you that fiberglass or mineral wool are definitely your best option for insulating the attic. This attic insulation is also inflated with a blowing machine, although the material used is different.
