Fiber Glass

Fiberglass is probably the most common material. It’s budget-friendly, and newer products don’t irritate the skin and lungs. Fiberglass insulation is manufactured to slow airflow through the material.

Building professionals and homeowners choose fiberglass insulation because of its effectiveness, safety, and value. It won’t deteriorate over time or lose its insulating power (R-value). It’s made from molten sand and recycled glass, rendering it naturally noncombustible, and a plant-based binder with no added formaldehyde, harsh acrylics, dyes or unnecessary fire retardants. Plus, fiberglass insulation can reduce energy costs*, provide interior and exterior sound control, and it’s safe to manufacture and install.
