What materials are most loose fill insulation typically made from?

Loose fill insulation is primarily made from materials that have strong thermal performance and can effectively fill cavities and irregular spaces. Fiberglass and cellulose are two of the most common types of loose fill insulation.

Fiberglass is created from fine glass fibers and is known for its resistance to moisture, contributing to its effectiveness in various climates. It has a high R-value per inch, making it a popular choice for insulation where high thermal resistance is desired.

Cellulose, on the other hand, is primarily made from recycled paper products and is treated with fire retardants. It offers good thermal insulation properties as well and is often considered more environmentally friendly than fiberglass, as it utilizes reclaimed material. It also performs well in sound attenuation and can help with air sealing in irregular spaces.

These materials are chosen for their effectiveness, ease of installation, and insulation properties, making them ideal for loose fill applications in attics and wall cavities. The combination of these materials addresses both thermal and acoustic performance, which is crucial for comfortable living environments.
