Fiberglass insulation is a widely used thermal insulation material made from fine glass fibers. Available in batts, rolls, or loose-fill forms, fiberglass insulation is installed in walls, attics, and floors to reduce heat transfer and improve energy efficiency in buildings. Its lightweight and flexible nature make it easy to handle and install, while its non-combustible properties enhance fire safety. Fiberglass insulation is valued for its affordability, durability, and effectiveness in reducing heat loss and noise transmission. It is a popular choice for both residential and commercial construction projects due to its versatility and proven performance in enhancing indoor comfort and energy savings.
