Description
Specifications

BSTFLEX Heat Reflective Aluminized Fiberglass Fabric is made by laminating aluminum foil or aluminized film to a fiberglass base cloth. The fiberglass layer provides heat resistance, tensile strength, and dimensional stability, while the aluminum surface reflects radiant heat and helps form a vapor barrier for insulation systems.

This aluminized fiberglass fabric is widely used for removable insulation blankets, pipe wrapping, turbine blankets, flange covers, exhaust heat shields, welding protection, thermal reflective liners, and industrial equipment insulation. It is suitable for applications where radiant heat reflection, flame resistance, lightweight structure, and flexible fabrication are required.

Product Advantages

The aluminum laminated surface reflects radiant heat away from protected components, while the fiberglass fabric supports high-temperature insulation and mechanical strength. This makes the fabric suitable for both industrial insulation and automotive heat protection applications.

High radiant heat reflection: helps reduce heat transfer from exhaust systems, steam pipes, furnaces, boilers, turbines, and heated equipment.
Fiberglass reinforcement: provides good tensile strength, flexibility, and fabrication stability.
Vapor barrier effect: the aluminum surface helps improve moisture and vapor resistance in insulation systems.
Lightweight and flexible: easy to cut, wrap, sew, laminate, and fabricate into custom insulation parts.
Good flame resistance: suitable for thermal protection, fire-resistant lining, welding protection, and safety covers.
Multiple constructions: available with filament fiberglass fabric or texturized fiberglass fabric depending on insulation thickness and flexibility requirements.
Custom production: one-side aluminum, two-side aluminum, special thickness, special width, cut pieces, and sewn parts are available.

FAQ

What is aluminized fiberglass fabric?

Aluminized fiberglass fabric is a thermal insulation fabric made by laminating aluminum foil or aluminized film to fiberglass cloth. The aluminum surface reflects radiant heat, while the fiberglass base provides heat resistance, flexibility, and mechanical strength.

What is this heat reflective fabric used for?

It is used for removable insulation blankets, pipe wrapping, turbine blankets, flange covers, valve covers, exhaust heat shields, welding blankets, fire-resistant curtains, and thermal reflective liners.

Can you supply one-side and two-side aluminum laminated fabric?

Yes. BSTFLEX can supply one-side or two-side aluminum laminated fiberglass fabric depending on the required heat reflection, vapor barrier, and installation conditions.

What is the difference between filament and texturized aluminized fiberglass fabric?

Filament aluminized fiberglass fabric has a smoother and thinner structure. Texturized aluminized fiberglass fabric uses bulked fiberglass yarn and provides more thickness, softness, and insulation volume for insulation blankets and pipe covers.

Can this fabric be sewn into insulation covers?

Yes. Aluminized fiberglass fabric can be cut and sewn into removable insulation blankets, pipe covers, flange covers, valve covers, turbine blankets, and custom heat protection parts.
