Braided Fibreglass & Ceramic Seals – High-Temperature Static Sealing
Thermal Barrier Rope & Tape for Kilns, Boilers & Furnaces

Our braided fibreglass and ceramic seals are designed for static sealing in high-temperature environments, providing excellent thermal insulation and mechanical stability. Available in both square and round braid configurations, these ropes and gaskets are flexible enough for tight sealing, yet durable enough to maintain structure under extreme heat and vibration.

Ideal for sealing access doors, hatches, and inspection ports in industrial heating systems, these seals help reduce heat loss, prevent leaks, and extend equipment life.

Material Options:

• Fibreglass Rope (550°C) – Cost-effective and heat-resistant, suitable for general-purpose sealing in ovens, boilers, and furnaces
• Ceramic Fibre Rope (1260°C) – High-performance rope for extreme heat environments such as kilns, burner assemblies, and refractory lining gaps

Common Applications:

• Boiler and furnace door seals
• Oven hatch and inspection port gaskets
• Kiln car and burner block seals
• Static sealing in thermal barrier and refractory systems

Available Sizes:

• Multiple diameters and cross-sections available in round or square braid
• Custom cut lengths or continuous rolls for on-site insulation work

For compression-based sealing of moving equipment, view our Valve & Pump Packings.

Also available: Fibrefrax QF180 Refractory Coating – a compatible high-temperature coating used to seal gaps or reinforce surrounding insulation surfaces.
