HIGH-TEMPERATURE INSULATION TAPE

Fibreglass Tape – 550°C Heat-Resistant Woven Insulation
Flexible Thermal Tape for Sealing, Lagging & Wrapping

Our 550°C-rated Fibreglass Tape is a plain woven, industrial-grade thermal tape designed for durability and high performance in extreme heat environments. Incombustible and flexible, it’s widely used for sealing, lagging, wrapping, and insulating applications where reliable heat protection is essential.

Suitable for use in boiler rooms, plant maintenance, and electrical systems, this tape provides a flame-resistant barrier while maintaining mechanical integrity under thermal and vibration stress.

Key Features:

Temperature Rating: Continuous service up to 550°C
Incombustible: Flame-resistant and asbestos-free for safe use in industrial environments
Flexible Woven Design: Plain weave construction ensures strength and ease of handling
Durable & Versatile: Resistant to fraying and thermal degradation

Specifications:

Thickness: 1.5 mm, 3.0 mm, 6.0 mm
Widths:
- 1.5 mm thickness: 25 mm, 40 mm, 50 mm
- 3.0 mm & 6.0 mm thickness: 25 mm, 40 mm, 50 mm, 75 mm, 100 mm
Length: 30 metre rolls

Common Applications:

Duct and pipe lagging insulation
Furnace and oven door gasket sealing
Insulating hot surfaces, valves, and flanges
Thermal shielding in electrical systems
General-purpose high-heat wrapping

Often used alongside fibreglass rope and tadpole tape in sealing systems across boilers, kilns, and ductwork.

Common High-Temperature Tape Applications ▾

High-temperature insulation tapes are used throughout industrial plants to reduce heat loss, improve safety and create reliable seals around equipment operating at elevated temperatures. The guide below outlines the most common applications and the tape typically recommended.

Application	Recommended Tape	Why?
Pipe insulation & lagging	Fibreglass Tape	Flexible, economical and ideal for wrapping hot pipework.
Flanges & bolted joints	Fibreglass Ladder Tape	Open-centre design allows bolts to pass through without cutting holes.
Boiler, furnace & oven doors	Fibreglass Tadpole Tape	Compressible bulb seal accommodates uneven gaps and door movement.
Peel-and-stick door seals & gaskets	Fibreglass Folded Laminated Tape	Pressure-sensitive adhesive provides quick installation.
Protecting cables & hydraulic hoses	Armasil AT Silica Tape	Excellent heat shielding with self-adhesive backing for easy installation.
Heavy-duty industrial insulation	Basalt Tape	Greater mechanical strength than standard fibreglass tapes.
Extreme heat & asbestos replacement	Ceramic Fibre Tape	Designed for continuous temperatures up to 1260°C.

If your application involves unusual temperatures, movement, chemicals or custom sealing requirements, contact our team. We'll help you select the most suitable tape for your equipment and operating conditions.

Replacing Asbestos Tape? ▾

Many older boilers, furnaces, kilns and industrial plants originally used asbestos tape for thermal insulation and sealing. Today, several modern high-temperature tapes are commonly used as safer alternatives, depending on the operating temperature and application.

If you're replacing...	Recommended Tape	Typical Use
General asbestos insulation tape	Fibreglass Tape	Wrapping pipes, valves, ducting and general thermal insulation up to 550°C.
Asbestos flange tape	Fibreglass Ladder Tape	Bolted flanges where the tape needs to fit around studs and bolts.
Asbestos door gasket	Fibreglass Tadpole Tape	Boiler, furnace, kiln and oven doors requiring a compressible seal.
Self-adhesive asbestos tape	Fibreglass Folded Laminated Tape	Quick installation where pressure-sensitive adhesive is preferred.
Higher-temperature asbestos tape	Armasil AT Silica Tape or Basalt Tape	Applications requiring improved heat resistance and greater durability.
Extreme-temperature asbestos tape	Ceramic Fibre Tape	Furnaces, kilns and equipment operating at temperatures up to 1260°C.

Important

There is no single replacement for every asbestos tape application. The correct product depends on the operating temperature, sealing pressure, equipment design and installation method. If you're replacing an existing asbestos tape and are unsure which product is most suitable, contact our team for advice.
