What Is Aluminium Coated Self-Wrapped Fibreglass Sleeve?
AG’s Aluminium Coated Self-Wrapped Fibreglass Sleeve is a flexible thermal protection solution designed to shield hoses, cables and wiring from radiant heat exposure. Manufactured from woven fiberglass and laminated with a reflective aluminium outer layer, this sleeve helps reduce heat transfer while maintaining flexibility and durability in demanding environments.
Its self-wrapping construction allows the sleeve to be opened and installed around existing lines without the need for disassembly, making it a practical choice for maintenance, retrofitting and tight installation spaces.
Typical Applications
This aluminium coated self-wrapped fiberglass sleeve is widely used across industries where heat protection is critical. Common applications include automotive engine bays, hydraulic and pneumatic hose protection, industrial machinery, exhaust proximity shielding, cable and wiring looms, and general thermal insulation in high-temperature environments. The reflective aluminium surface makes it especially effective in areas exposed to radiant heat sources.
Key Features & Benefits
-
Self-wrapping, overlapping design for easy installation without disconnecting hoses or cables
-
Aluminized outer layer reflects radiant heat away from critical components
-
Fiberglass core provides reliable thermal insulation and heat resistance
-
Flexible construction allows installation in confined or complex routing areas
-
Helps extend the service life of hoses, wiring and cables by reducing heat exposure
-
Suitable for industrial, automotive and general heat-shielding applications
Performance & Construction
The sleeve combines a woven fiberglass inner layer with an aluminized outer surface to deliver both insulation and heat reflection. This dual-layer construction makes it well suited to environments where radiant heat is the primary concern, while still offering mechanical flexibility and durability.

Why Choose a Self-Wrapped Heat Sleeve?
Unlike rigid or closed-end sleeves, the self-wrapped design significantly reduces installation time and labour costs. It allows existing systems to be upgraded with thermal protection during maintenance or repairs, without shutting down or dismantling equipment.
This makes the self-wrapped aluminized fiberglass sleeve a cost-effective and practical solution for improving safety, reliability and component lifespan in heat-intensive environments.
