The most common types of materials used for loose-fill insulation include cellulose, fiberglass, and mineral (rock or slag) wool. All of these materials are produced using recycled waste materials. Cellulose is primarily made from recycled newsprint. Most fiberglass products contain 40% to 60% recycled glass.
What Types of Insulation?
There are four main types of insulation: fiberglass, cellulose, spray foam, and rigid foam. Each has its own set of benefits and drawbacks, so it’s important to choose the right one for your needs.
Fiberglass is the most common type of insulation. It’s made from recycled glass and sand, and it’s available in both rolls and batts.
Fiberglass is an effective insulator and it’s easy to install, but it can be itchy and difficult to work with. Cellulose is made from recycled paper products, and it’s often treated with fire retardants.
It’s available in loose–fill and batts, and it can be sprayed in. Cellulose is an effective insulator, but it’s not as effective as fiberglass.
It can also be difficult to install. Spray foam is made from polyurethane and it’s available in two types: closed–cell and open–cell.
Closed–cell spray foam is the most effective type of insulation, but it’s also the most expensive. Open–cell spray foam is less effective, but it’s less expensive and
