Textiles for fire containment blankets with proven aviation technology

Textile shields for the future of fire protection

Smoke curtains and fire curtains are key components of preventive fire protection. They serve to create fire and smoke compartments in buildings and protect people, property, as well as escape and rescue routes. As a manufacturer of technical high-temperature fabrics made from, among others, glass fibers, we provide the
foundation for innovative fire protection systems – high-temperature-resistant, tested materials that comply with the required fire resistance classes. Optimized weaves and advanced coatings support modern, efficient fire protection systems (E, EW, EI). Lighter and more adaptable than steel, fire curtains integrate seamlessly into contemporary architecture, meeting the demand for flexible, discreet fire protection.

Possible Certifications

A large selection of our fabrics meet the European requirements for fire protection and are certified in accordance with DIN EN 13501 for the fire classification of construction products and building elements: A2-s1, d0 (also MO, M1)

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.
