Details
Aluminum Coated Fiberglass Cloth (also known as Aluminized Fiberglass Fabric) is a high-performance composite material manufactured by laminating premium E-glass fiber cloth with aluminum foil via advanced bonding technology. Leveraging the high strength of E-glass fiber and the excellent heat reflection of aluminum foil, this product delivers outstanding thermal insulation, fire resistance, and corrosion protection. Aluminum Coated Fiberglass Cloth is widely used as a safety protection material for hazardous material production, storage, and transportation, and also provides reliable protection for various outdoor piping systems and industrial equipment.
Unlike silicone coating which provides insulation through thermal resistance, aluminum coating works primarily through radiant heat reflection (reflecting up to 90% of radiant heat) while the fiberglass provides a thermal barrier against conducted heat.

How many types of aluminum coated fiberglass cloth are there?
By Lamination Side
oSingle-Sided Aluminum Coated Fiberglass Cloth: Aluminum foil laminated on one side of E-glass fiber cloth. Cost-effective, suitable for one-way heat insulation and protection scenarios (e.g., simple pipe insulation, temporary protective covers).
oDouble-Sided Aluminum Coated Fiberglass Cloth: Aluminum foil laminated on both sides. Symmetrical performance, better heat insulation and corrosion resistance, ideal for high-demand applications (e.g., high-temperature equipment insulation, hazardous material packaging).
By Adhesive Configuration
oSelf-Adhesive Aluminum Coated Fiberglass Cloth: With self-adhesive backing, easy to paste and install, no additional adhesive required. Suitable for quick installation scenarios (e.g., small-diameter pipe insulation, equipment local protection).
oNon-Adhesive Aluminum Coated Fiberglass Cloth: No adhesive layer, featuring higher flexibility and tensile strength. Widely used in scenarios requiring sewing, welding, or secondary processing (e.g., fire isolation covers, large-scale equipment insulation jackets).
What are the advantages and benefits of aluminum coated fiberglass cloth?
Material | Advantages of Aluminum Coated Fiberglass |
Uncoated Fiberglass | Superior radiant heat protection, moisture barrier, UV protection, better visibility in work areas (reflective). |
Silicone Coated Fiberglass | Better radiant heat reflection (not just insulation), lighter weight, wider high-temperature range, won't degrade from UV. |
Solid Aluminum Sheet | Far more flexible, lighter, allows airflow, better conformability, easier installation on complex shapes. |
Aluminum Foil | Much more durable, tear-resistant, flameproof, reusable, handles higher temperatures. |
Carbon Fiber Composites | More cost-effective for thermal applications, better radiant reflection, non-conductive (electrically). |

How to store and handle aluminum coated fiberglass cloth?
The following suggestions are suggested to preserve product performance, although no particular storage measures are needed:
1. Keep out of direct sunlight, high temperatures (over 40°C), and excessive humidity (relative humidity > 80%). Store in a dry, cool, and well-ventilated area.
2. To prevent harming the aluminum foil layer and fiberglass foundation, shield the product from contamination by oil, chemicals, and sharp objects.
3. To minimize long-term folding and irreversible creases or delamination, store the goods in rolls or flat sheets.
4. Under ideal storage conditions, a 12-month storage time following the manufacture date is advised. It is advised to verify the product's integrity prior to use if it is kept longer than this time.
5. Mixed storage with other non-toxic, non-corrosive items is not subject to any particular limitations.
FAQ
Q1: Does the aluminum coating wear off or oxidize?
A: Yes, over time and with handling or abrasion, the thin aluminum layer can dull from oxidation (forming aluminum oxide, which is chemically stable but less reflective). Top-coated versions significantly extend reflective life. The material remains functional as a thermal barrier even when dulled, though radiant reflection decreases from ~90% to ~70%.
Q2: Can aluminum coated fiberglass cloth be used for direct flame contact?
A: Standard E-glass aluminum cloth is NOT designed for direct flame impingement. The aluminum melts at 660°C, and E-glass degrades above 600°C. For flame contact, specify alumina-silica base fabric with aluminum coating, rated up to 1000°C.
Q3: Is aluminum coated fiberglass cloth electrically conductive?
A: YES. This is critical. The aluminum surface is electrically conductive. It can cause shorts if it contacts electrical components. Ensure proper electrical isolation in design. Some specialized versions have a clear dielectric overcoat for electrical applications.
Q4: Can aluminum coated fiberglass cloth be washed or cleaned?
A: Light cleaning with mild soap and water is acceptable. Do not machine wash or use harsh chemicals. For heavily soiled industrial applications, it's often more economical to replace the material.
Q5: What is the lifespan in outdoor applications?
A: Unprotected aluminum coating will oxidize to a stable gray matte finish within 6-18 months outdoors, depending on environment. Top-coated versions can last 3-5 years. The underlying fiberglass remains intact for 5-10+ years.
Q6: Can aluminum coated fiberglass cloth be repaired if torn?
A: Small tears can be patched using high-temperature aluminum tape on both sides. For larger damage, the section should be replaced, as the thermal performance is compromised.
Q7: Does aluminum coated fiberglass cloth have an adhesive layer?
A: Yes, we offer self-adhesive aluminum coated fiberglass cloth with a high-quality self-adhesive backing for easy installation. Non-adhesive versions are also popular and widely used for secondary processing.
Q8: Can we request a special thickness for the aluminum foil?
A: Yes, customized aluminum foil thickness is available. Please provide your specific technical requirements, and we will adjust the production process accordingly to meet your needs.
Q9: Is aluminum coated fiberglass cloth suitable for marine environments?
A: Yes, aluminum coated fiberglass cloth has good corrosion resistance to saltwater and humid marine environments, making it widely used in shipbuilding and offshore platform equipment insulation and protection.
