Fiberglass insulation is a popular and effective choice for improving attic insulation and ensuring cleaner indoor air. It's widely used due to its affordability, ease of installation, and excellent thermal performance. Fiberglass insulation is made from tiny glass fibers that are spun together to create a fluffy material. It's available in batts, rolls, or loose-fill forms, making it suitable for various attic spaces.

One of the benefits of fiberglass insulation is its ability to resist moisture. This helps prevent the growth of mold and mildew, ensuring a healthier indoor environment. Additionally, fiberglass insulation is non-combustible, providing an added layer of fire protection. It also acts as a sound barrier, reducing noise transmission between different areas of the house.

While fiberglass insulation is a popular choice, there are alternatives available. Some homeowners opt for cellulose insulation, which is made from recycled paper products. Cellulose insulation has similar thermal performance to fiberglass and is an environmentally friendly option.

Another alternative is spray foam insulation, which provides superior air sealing and insulation properties.

Cellulose Insulation

As we explore alternative options for attic insulation, one environmentally friendly choice that homeowners often consider is cellulose insulation. Made from recycled materials such as newspaper, cellulose insulation is an effective way to improve energy efficiency and reduce air leakage in the attic.
