Fireproof and Heat Resistant Aluminum Foil Fiberglass Cloth for Industrial Protection and Insulation
Description
This foiled fiberglass fabric is made from high-quality 3732 woven fiberglass cloth (430 g/m²) laminated with a reflective aluminum foil layer. The finished composite fabric provides enhanced heat reflection and insulation performance.
Total weight: 480 g/m²
Total thickness: 0.43 mm
The 3732 fiberglass base fabric performs reliably in continuous temperatures ranging from -50°C to 260°C (-58°F to 500°F), withstanding brief exposure to even higher temperatures. The foil adhesive layer—made of hydrogel or acrylate adhesive—is recommended for use below 300°C, ensuring strong and durable bonding between the fiberglass and aluminum layers.
The aluminum foil significantly improves heat resistance and radiant heat reflection, while also providing moisture and chemical resistance. Though aluminum melts at high temperatures, it requires sustained heat to reach that point, allowing the fabric to tolerate short-term exposure above its rated temperature.
Aluminum foil thickness options: 7 μm, 18 μm, 25 μm, 50 μm (max)
Common widths: 100 cm / 127 cm / 150 cm
Roll length: 50–100 meters
This composite material is widely used for thermal insulation, heat shields, engine and equipment protection, welding curtains, and fire-resistant barriers.
