Cellulose Attic Insulation
What You Need To Know
When it comes to attic insulation, choosing the right material can significantly impact your home’s energy efficiency and comfort. We trust Owens Corning, the #1 most trusted brand of insulation*. Let’s explore cellulose insulation and why Owens Corning PROPINK L77 stands out as a preferred choice.
What is Cellulose Insulation
Cellulose insulation is a home insulation made from recycled paper products, primarily newspapers. It’s treated with fire retardants to enhance safety and is installed by blowing it into attics and wall cavities. Despite being environmentally friendly due to its use of recycled materials, cellulose insulation may not be the best choice for home efficiency. It can settle over time, reducing its insulating effectiveness and creating gaps that allow air leakage. Additionally, cellulose can absorb moisture, leading to mold growth and compromising its insulating properties. This moisture absorption can also contribute to the deterioration of building materials, potentially leading to costly repairs. Consequently, homeowners might experience higher energy bills and increased maintenance costs when using cellulose insulation.
Owens Corning PROPINK L77
Owens Corning PROPINK L77 is a high-performance loose-fill fiberglass insulation designed to deliver outstanding thermal efficiency. Unlike cellulose, PROPINK L77 offers consistent coverage without settling over time, ensuring long-lasting performance. Its unique composition allows for easy installation, making it ideal for both new construction and retrofit projects.
- Excellent thermal and acoustical performance
- Non-corrosive and non-combustible
- Does not require wet adhesives or fire-retardant chemicals
