    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.

    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.
