How Does Insulation Reduce Noise?

Limiting the transmission of sound from one location to another requires a material that encloses the source of the noise and forms a barrier between the source and the adjacent area. This is exactly what insulation does. Fiberglass and cellulose are the best types of insulation for soundproofing purposes.

How Is Cellulose Environmentally Friendly?

Cellulose insulation consists of up to 80 percent recycled material (primarily newspaper), and it takes less energy to make than other types of insulation. If the paper put into landfills every year were used to make cellulose insulation, it would save approximately eight million tons of CO2 emissions!

What Is Cellulose Insulation?

Cellulose insulation is a loose-fill material made mostly from recycled paper fibers that are treated for fire resistance and durability. It’s installed using specialized equipment that blows the material into attics, walls, and other hard-to-reach areas to create a dense, effective thermal barrier.

Because it fills gaps and conforms to irregular spaces, cellulose helps reduce air leaks and improve overall home efficiency.

Where Can Cellulose Insulation Be Installed?

Cellulose insulation is a versatile solution that works well in both new construction and retrofit projects. It’s commonly installed in:

Attics (most popular application)
Wall cavities
Floors and ceilings
Crawl spaces

It’s especially effective for older homes that need improved insulation without major renovations.
