Cellulose insulation is a type of thermal insulation made primarily from recycled paper products, such as newspapers. It is treated with fire retardants to enhance safety and is often used in residential and commercial buildings. This eco-friendly material is known for its excellent thermal performance and soundproofing qualities. The installation process typically involves blowing the cellulose into wall cavities or attics, creating a dense barrier that helps regulate indoor temperatures. Cellulose insulation is also resistant to pests and mold, making it a durable choice for energy efficiency and comfort in various climates.
