Aluminized Fiberglass Fabric: High-Performance Heat and Flame Protection
Aluminized Fiberglass Fabric: High-Performance Heat and Flame Protection
June 08 , 2025
What is Aluminized Fiberglass Fabric?
Aluminized fiberglass fabric is a high-temperature resistant textile made by bonding or laminating a reflective aluminum foil layer onto a woven fiberglass substrate. This combination provides both the strength and heat resistance of fiberglass and the radiant heat reflectivity of aluminum. The result is a versatile, durable material that protects against extreme temperatures, radiant heat, sparks, and abrasion in a wide range of industrial applications.
The fiberglass component offers excellent tensile strength, thermal insulation, and flame resistance, while the aluminum surface reflects up to 95 percent of radiant heat. This makes aluminized fiberglass fabric an ideal solution for both direct-contact heat protection and environments where radiant heat is the primary concern.
Key Features and Benefits
Heat Resistance Aluminized fiberglass fabric withstands continuous exposure to temperatures up to 550°C (1022°F) on the fiberglass side. The aluminum foil reflects radiant heat from sources exceeding 1000°C (1832°F), effectively shielding nearby components and surfaces from heat damage.
Radiant Heat Reflection The aluminum coating reflects radiant heat away from sensitive areas, helping to reduce heat soak and maintain system stability. This is especially useful in automotive, industrial, and aerospace applications.
Durability and Strength The woven fiberglass core provides exceptional tensile strength and structural integrity, even in high-vibration or mechanically demanding environments. It resists fraying, tearing, and general wear under repeated use.
Chemical and Moisture Resistance The fabric is resistant to many industrial chemicals, solvents, oils, and moisture. It performs well in corrosive environments and retains its protective properties over time.
Flexibility and Lightweight Design Despite its strength and protective capabilities, aluminized fiberglass fabric is lightweight and flexible. It can be cut, sewn, wrapped, or fitted around irregular shapes, making it suitable for custom installations or confined spaces.
Fire Resistance The fiberglass core is inherently non-combustible, while the aluminum foil provides an extra barrier against flame and molten splash. It is suitable for use in fire curtains, welding blankets, and protective gear.
Common Applications
Aluminized fiberglass fabric is used across a wide range of industries where heat shielding and fire protection are critical.
Automotive and Motorsport Commonly used for wrapping exhaust pipes, turbo systems, and heat shields. It protects wiring, fuel lines, and other sensitive components from engine heat.
Industrial and Manufacturing Used in foundries, steel mills, and fabrication shops to create welding curtains, thermal barriers, and machine covers. Protects both workers and equipment from sparks and radiant heat.
Aerospace and Aviation Offers thermal protection in aircraft and spacecraft systems where weight, fire resistance, and flexibility are essential. Also used in insulation blankets and radiant shields.
Fire Protection and Safety Gear Integrated into fire proximity suits, blankets, gloves, and protective curtains. Provides thermal shielding for firefighters, welders, and personnel exposed to high temperatures.
HVAC and Insulation Systems Used to insulate ducts, pipes, and furnaces, reducing heat loss and improving energy efficiency in industrial and commercial systems.

Why Choose Aluminized Fiberglass Fabric?
Aluminized fiberglass fabric is a trusted solution for environments that demand both thermal insulation and mechanical durability. It serves as a protective barrier against heat, flames, and abrasion while remaining lightweight and easy to handle. Unlike rigid insulation panels or metal shields, it conforms easily to complex shapes and surfaces.
The combination of fiberglass and aluminum results in a fabric that is both functional and cost-effective. It can be fabricated into removable insulation jackets, pipe wraps, protective sleeves, and custom insulation components. Its wide range of operating temperatures and environmental resistance make it a go-to solution for engineers and safety managers across multiple industries.
Whether your application involves high-speed engines, heavy-duty machinery, or exposure to open flame, aluminized fiberglass fabric offers consistent protection and performance.
Frequently Asked Questions
Is aluminized fiberglass fabric waterproof? The aluminum foil offers some resistance to moisture, but the fabric itself is not entirely waterproof. In wet environments, sealing or additional laminations may be required for full water resistance.
Can the fabric be sewn or bonded? Yes, it can be sewn using high-temperature thread or bonded with industrial adhesives designed for thermal insulation. It is commonly used in custom insulation blankets, curtains, and jackets.
Does the aluminum layer degrade over time? The aluminum layer maintains reflectivity for an extended period but may wear down under heavy abrasion or in corrosive conditions. Embossed aluminum or reinforced versions offer longer lifespan in demanding applications.
Is it safe for use near open flame? Yes. The fiberglass is non-combustible, and the aluminum layer reflects heat. The material is widely used in fire protection gear and thermal barriers.
Aluminized fiberglass fabric is an essential material for high-heat environments where thermal protection, fire resistance, and mechanical durability are required. It combines the proven strength of fiberglass with the reflective performance of aluminum, making it suitable for applications ranging from automotive heat shields to industrial fire curtains.
With customizable thicknesses, excellent heat resistance, and superior flexibility, this fabric continues to meet the demands of modern industry. Whether you are insulating machinery, protecting cables, or developing safety gear, aluminized fiberglass fabric offers long-lasting and dependable performance.
