Innovative fire protection systems for preventive fire protection

Focus on battery safety

Lithium-ion batteries pose particular risks: A so-called thermal runaway can lead to intense heat, flames, smoke, and toxic gases within seconds. Rapid, safe containment is crucial, especially for electric vehicles, e-scooters, and e-bikes in underground garages, residential complexes, charging and parking stations, or stationary storage facilities. In workshops, test laboratories, or transport vehicles, our fabric helps to limit battery fires.

Technical textiles for fire containment blankets

• Material: High-quality glass or silicate fabric with special functionalization
• Temperature resistance: Permanent up to 550 °C, short-term > 1,000 °C
• Suppresses flame spread and protects adjacent objects
• Reduces heat transfer to the outside
• Non-combustible, flame-retardant, and spark-resistant
• Minimizes smoke and gas release into the environment

Proven technology from aviation

Fire containment covers (FCCs) made from similar glass fabrics have been used in air traffic control for years. These covers serve to isolate burning cargo on board aircraft for 6 hours, giving the flight crew valuable time to make a safe landing. Our expertise in developing such FCCs flows directly into the manufacture of our fire containment blankets. As a result, you benefit from:

• Aviation-proven materials with maximum safety
• Proven technologies for controlled fire containment
• Internationally recognized standards in the field of fire containment

Efficiency meets safety

In industrial high-temperature environments, every degree counts. As a leading manufacturer of technical textiles for heat and flame protection applications, we supply tailor-made insulation solutions that perform where standard materials have long since reached their limits.

Our highly specialized fabrics made of glass fiber, silicate, and aramid offer reliable protection well above 1000°C – in metal processing, thermal plants, power plants, foundries, and mechanical engineering. Whether as flexible insulation mats, custom-made protective covers, or removable valve insulation, our textiles combine maximum thermal performance with mechanical resilience and ease of use.

Technical textiles are often used as thermal insulators, especially at high temperatures.

Applications

• Pipe and plant insulation: Textile-coated insulation mats (e.g., made of glass fiber, silicate, aramid) prevent heat loss from heating pipes, furnaces, or turbines, sound insulation.
• Cable sheathing with heat- and tension-resistant textiles (e.g., glass silk with silicone).
• Welding curtains & heat shields: Protection in welding halls, foundries, and metal processing.
• Heat-resistant jackets: Removable insulating covers for valves, pumps, flanges – facilitate maintenance and save energy

Advantages of technical textiles in insulation

• High temperature resistance – ideal for continuous use in industrial environments
• Excellent thermal insulation properties combined with low material weight
• Resistance to chemicals, moisture, and UV radiation
• Flexibility and easy processing
• Adaptability to complex shapes

Rely on innovative insulation solutions – made for extremes.

Proven quality, next-level performance

Our proven Sestonit® fabric with special treatment has long been the go-to material for high-temperature applications. Whether for chimney and furnace insulation, gas turbines, foundries, or the automotive industry, Sestonit® delivers reliable performance wherever extreme heat demands it.

The new generation, Sestonext, takes performance to the next level:

• Short-term use up to 1,300 °C (4 hours)

• Increased strength while maintaining a textile feel

• Residual strength of about 20 % at 105 N/cm

Building on the trusted quality of Sestonit, Sestonext combines enhanced thermal performance with a proven textile character, enabling even more demanding applications at the highest temperatures.

with conduction, convection and radiation in just one layer

With its innovative multi-layer design, our new advanced intumescent flexible glass fabric sandwich
structure sets new standards in safety and efficiency. Built from a smart combination of aluminum foils,
fiberglass fabric with wire reinforcement and intumescent bonding layers it delivers superior protection by
addressing all three mechanisms of heat transfer.
When exposed to heat, the special intumescent adhesive combining both textile layers expands into a
highly effective insulating layer filled with microscopic air pockets. Forming a stable network of foamed
carbon, this unique barrier dramatically slows the transfer of heat and prevents flames from breaking
through. Meanwhile, reflective aluminum layers on both sides act like a shield, bouncing back radiant heat
for extra protection.
Unlike conventional multi-layer systems, which are stitched together and prone to wear, our development
features a fully bonded structure. This eliminates weak points and avoids mechanical friction. At the same
time, installation and further processing are easier, as all performance layers come integrated in one
compact and elegant system.
