Foil-faced glass wool blankets are high-performance thermal and acoustic insulation materials. Made of recycled glass fibers formed into a lightweight, flexible blanket and laminated with an aluminum foil facing, they provide superb heat and sound control. Ideal for attic and wall installations, these blankets significantly boost energy efficiency and are moisture-resistant, fire-rated and easy to install between framing.
1) Thermal Performance: Glass wool itself has outstanding thermal insulation properties, effectively reducing heat transfer. With the addition of the aluminum foil layer, the foil reflects radiant heat, further enhancing the insulation effectiveness. This structure helps to minimize energy consumption and improve the overall energy efficiency of buildings.
2) Vapor Barrier: The aluminum foil layer acts as an effective vapor barrier, preventing the penetration of moisture and condensation into the insulation material. This feature helps to maintain the insulation's thermal performance over time and protects the underlying construction materials from potential moisture-related damage.
3) Fire Resistance: Foil-faced glass wool insulation is typically manufactured with fire-resistant properties. The aluminum foil layer provides an additional layer of protection, acting as a barrier against the spread of flames and reducing the fire risk.
4) Acoustic Performance: In addition to thermal insulation, glass wool has excellent sound absorption properties. When combined with the aluminum foil layer, foil-faced glass wool insulation provides enhanced acoustic performance by reducing sound transmission, creating a quieter and more comfortable indoor environment.
Foil-faced glass wool insulation is commonly used in a variety of applications, including residential, commercial, and industrial buildings. It is particularly suitable for insulating walls, roofs, floors, and HVAC ducts, where both thermal and acoustic insulation are required.
Overall, foil-faced glass wool insulation offers an efficient and versatile solution for improving energy efficiency, moisture control, fire safety, and acoustic comfort in buildings.
