Non-woven aluminum foil (40 mic) for phenolic board is a special type of material used in insulation applications. This product is normally made up of a layer of nonwoven fabric bonded with aluminum foil, which works as a heat and moisture barrier. The 40-mic thickness specifies the gauge of the aluminum foil layer, which provides a long-lasting and effective protection for phenolic boards used as insulation. The nonwoven fabric adds strength and flexibility to the material, making it ideal for wrapping or coating phenolic boards to improve their thermal insulation capabilities. This form of non-woven aluminum foil is widely utilized in construction and building applications requiring thermal insulation and moisture resistance.
The combination of non-woven fabric with aluminum foil produces a versatile material that can be used in a variety of industries, including construction, automotive, aerospace, and packaging. Non-woven aluminum foil is commonly used as insulation for walls, roofs, and HVAC systems in order to improve thermal efficiency and moisture resistance. The aluminum foil reflects heat and light, while the non-woven fabric adds mechanical strength and thermal insulation.
It is a specialized insulation material composed of a 40-micron thick aluminum foil layer laminated with high-strength non-woven fabric. It is specifically designed to cover and protect phenolic insulation boards used in HVAC and construction applications.
It is widely used in HVAC duct insulation, exterior wall and roof thermal insulation, cleanroom ductwork, and industrial building insulation systems to prevent heat loss and moisture ingress.
The aluminum foil acts as an excellent thermal reflector and moisture/vapor barrier, while the non-woven fabric provides superior mechanical strength, flexibility, tear resistance, and ease of lamination on phenolic boards.
Yes, the combination of aluminum foil and non-woven fabric provides high heat reflection and flame-retardant properties, making it safe for high-temperature and fire-rated insulation systems.
The 40-micron aluminum foil layer reflects up to 95-97% of radiant heat, while the moisture-proof barrier prevents humidity from degrading the core phenolic insulation board's thermal resistance.
