Our Fiberglass Cloth Aluminum Foil Tape is a heavy-duty, high-performance adhesive tape engineered for demanding thermal insulation, heat reflection, and industrial sealing applications. Combining a composite backing of high-tensile fiberglass cloth and reflective aluminum foil with a high-performance synthetic rubber-resin adhesive, this specialized Aluminum Foil Tape delivers exceptional tear resistance, temperature tolerance, and moisture protection.
Constructed using an advanced multi-layer lamination process, this reinforced tape features a durable backing composed of 7µm aluminum foil, flame-retardant adhesive, and a 110gsm 12×12 glass cloth weave protected by an easy-release silicone liner. The woven fiberglass cloth supplies structural durability and high resistance to punctures and tearing, while the outer aluminum foil layer offers superior heat reflectivity and thermal conductivity.
Formulated with a high-tack synthetic rubber-resin adhesive, Fiberglass Cloth Aluminum Foil Tape forms a durable barrier against air leakage, moisture ingress, dust, and environmental contaminants. Its flexible design allows it to conform effortlessly around corners and irregular surfaces, making it an essential solution for sealing HVAC ductwork joints, insulating high-temperature piping, shielding automotive engine compartments, and protecting sensitive electronics.

A: The composite backing consists of a 7µm aluminum foil layer laminated to a 110gsm 12×12 fiberglass cloth weave using flame-retardant glue.
A: The woven fiberglass cloth backing provides significantly higher tensile strength and tear resistance, allowing the tape to withstand physical stress, abrasion, and punctures that would cause plain foil tape to rip.
A: Yes. It is commonly used to seal joints and seams in HVAC ductwork, creating an airtight, moisture-resistant bond that prevents energy loss.
A: Yes. Despite its high strength, the tape remains flexible and conformable, allowing it to adhere smoothly around tight bends, pipe fittings, and textured surfaces.
A: Yes. Its reflective aluminum surface and heat-resistant properties make it ideal for protecting automotive wiring, hoses, and surrounding components from radiant heat in engine compartments.
