Fibreglass With Foil

Foil-faced fibreglass insulation is a non-combustible, fire-resistant material made from fine glass fibers, backed with a layer of aluminum foil. The foil acts as a radiant heat barrier and moisture retarder, making it suitable for thermal insulation in HVAC systems, walls, roofs, and high-temperature areas. It provides moderate sound absorption, resists mold and pests, and is commonly used where both thermal efficiency and fire resistance are needed.
