Cellulose insulation is the earliest form of home insulation and is still found in houses today. It can be either a loose-fill or blown-in insulation and can be used in both new and current houses. While foam is all we do, we understand a fair bit about traditional insulations like cellulose. We are on a mission to be transparent while educating homeowners on all things home insulation– even the materials we don’t install. Now, let’s begin on this academic journey to learn more about all the things you want to know about cellulose insulation.

Cellulose is a fiber insulation used in enclosed existing walls, open brand-new walls, and incomplete attic floorings. Numerous companies produce cellulose insulation, and it is mainly made from recycled newsprint. These small particles form an insulation material that conforms to many areas without disturbing the structure or surface. Cellulose is one of the earlier insulations but didn’t end up being a popular choice until the 1950s when fire retardant was contributed to the product.

What is Cellulose Insulation Made of?

Modern cellulose insulation is made from either 75 to 85 percent ground-up recycled paper or recycled jeans. It is greatly treated– around 15 percent by volume– with boric acid, borax, or ammonium sulfate. While these chemicals aren’t understood to be dangerous to people, they can be efficient flame retardants and help in reducing pest concerns. Wet-applied cellulose has water added during the installation process.

Cellulose insulation can be used in both existing houses and new construction. It can be blown as loose-fill insulation in attic cavities, dense loaded into walls and floors, or wet spray for new building and construction that assists increase heat retention and has the possible to dampen noise levels, according to the Energy Audit Blog. Dense pack cellulose is used more frequently today for adding retrofit insulation. The thick packing into the wall cavities includes a thermal insulation while offering some level of soundproofing. Wet-applied spray cellulose has water added to it throughout the application process. The product has the same thermal and sound retardant properties as dense packing, according to the Energy Audit Blog. Wet spray cellulose is usually installed in brand-new construction prior to the drywall is installed.
