Summary of our Top Rated

  • Top-rated cellulose insulation 2025

How Does Cellulose Insulation Work?

Cellulose insulation is an eco-friendly material primarily made from recycled paper products, such as newspapers and cardboard. When installed in your home, it fills the spaces in walls, attics, and floors, creating a barrier against heat transfer. This process helps to keep your home warm in winter and cool in summer, thereby enhancing energy efficiency. The cellulose fibers trap air pockets, which slow down the movement of heat, providing excellent thermal resistance, known as R-value. Additionally, cellulose insulation is often treated with fire retardants and pest repellents, making it a safe and effective choice for soundproofing and improving indoor air quality.
