Description

Made from recycled newspapers and cardboard, paper-based insulation is a great alternative to chemical foams. Both insect resistant and fire-retardant because of the inclusion of borax, boric acid, and calcium carbonate (all completely natural materials that have no associations with health problems), paper insulation can be blown into cavity walls, filling every crack and creating an almost draft-free space. It is also called cellulose insulation. Cellulose insulation is made from recycled paper products, primarily newsprint, and has a very high recycled material content, generally 82% to 85%. The paper is first reduced to small pieces and then fiberized, creating a product that packs tightly into building cavities and inhibits airflow. In new construction, cellulose can be either damp-sprayed or installed dry behind netting. When damp sprayed, a small amount of moisture is added at the spray nozzle tip, activating natural starches in the product and causing it to adhere inside the cavity. Damp-sprayed cellulose is typically ready for wall covering within 24 hours of installation. Cellulose can also be blown dry into netting stapled over building cavities. Cellulose is compared to spray foam and also fiberglass insulation. Being cheaper and more safe. Cellulose will change insulation by using recycled materials and by being a safer alternative with less chemicals than what most insulations have today.
