Fingerhuth welding blankets protect machinery, equipment, work areas and sensitive surfaces against sparks, weld spatter, molten metal splashes, flames and radiant heat. Depending on the application, different material systems made from glass fabric, Preox and high-temperature-resistant SiO₂ silica fabric are available.
Selection is determined not only by the maximum temperature, but also by spatter exposure, mechanical load, fabric weight and type of application. Our range therefore extends from lightweight spark protection blankets to heavy-duty silica welding blankets for extreme industrial hot work.
Our range includes welding, spark and spatter protection blankets for industrial applications. The individual grades differ in terms of temperature resistance, fabric weight, material construction and mechanical durability, enabling targeted selection for the respective application.
Temperature alone is not the only selection criterion. Spatter exposure, mechanical loads and the type of surface to be protected can significantly influence the appropriate material grade. We are happy to support you with the technical selection.
The appropriate welding blanket should not be selected solely on the basis of its maximum temperature resistance. Equally important are the type and intensity of thermal exposure, sparks and weld spatter, mechanical loads and the specific operating conditions. The following criteria provide guidance for the preliminary technical selection of the appropriate material grade.
The materials temperature resistance must match the actual thermal exposure. A distinction must be made between continuous temperature, short-term peak exposure and direct flame contact.
Light sparks impose different requirements on a protective blanket than intensive weld spatter or hot slag. The type, quantity and energy of the particles influence the required material construction.
Welding, cutting and hot work involving intensive spatter may require heavy, specially treated fabrics. In particular, molten metal splashes impose significantly higher demands than ordinary sparks.
If the welding blanket is moved regularly, pulled over edges or used repeatedly, fabric weight, fabric construction and mechanical durability play a decisive role.
If the primary exposure is intense radiant heat, a reflective surface may be more appropriate than simply selecting the highest possible temperature rating of the base fabric.
Sensitive painted surfaces, components or vehicle surfaces may impose specific requirements on material feel and fibre structure. The vertical or horizontal application, fastening method and available space also influence product selection.
Welding blankets are used during welding, grinding, cutting and hot work to protect adjacent machinery, components, surfaces and work areas against sparks, weld spatter, molten metal splashes, flames and thermal exposure. Depending on the application, requirements differ in terms of temperature resistance, fabric weight, surface characteristics and mechanical durability.

Großflächige Abschirmung bei Grinding Work zum Schutz der Umgebung vor Funkenflug und heißen Partikeln. Besonders relevant bei Arbeiten in unmittelbarer Nähe empfindlicher Anlagen und Bauteile.
Protection during thermally intensive cutting and torch processes involving hot particles, slag and molten metal splashes. Depending on the exposure, specially treated spatter protection blankets may be required.
Temporary protection during maintenance, repair and assembly work when welding, cutting or other thermal processes must be carried out within existing installations.

Schutz bei besonders hohen thermischen Belastungen, bei denen klassische Glasgewebe nicht mehr ausreichen. Hochtemperaturbeständige Gewebe wie SiO₂-Silikatmaterialien ermöglichen den Einsatz in extremen industriellen Temperature rangen.
Our specialists support you in selecting the appropriate welding blanket – matched to thermal exposure, sparks and weld spatter, mechanical loads, as well as the required dimensions and configuration.
Personal advice on product, configuration and application concept.
Selecting the appropriate welding blanket depends on several technical factors. In addition to temperature resistance, spark and spatter exposure, mechanical loads, material construction and application conditions also play an important role.
Choosing the right welding blanket depends on more than just the maximum temperature. Other important factors include the type and intensity of sparks or molten metal spatter, mechanical stress, installation conditions and the surface to be protected. For standard welding and grinding work, lighter glass-fabric grades are often sufficient, while higher temperatures or intensive molten metal spatter require more robust high-temperature or silica-fabric grades.
Depending on the material and design, our welding blankets cover different temperature ranges. Our product range extends from industrial glass-fabric welding blankets for temperatures up to 600 °C and high-temperature grades for applications up to approximately 1,100 °C to SiO₂ silica fabrics for extreme thermal exposure with short-term peak temperatures of up to 1,600 °C. A distinction must always be made between continuous operating temperatures and short-term peak temperatures.
Glass fabrics are a proven and cost-effective solution for a wide range of industrial welding, spark and heat protection applications. Silica fabrics, on the other hand, have a significantly higher SiO₂ content and provide greater thermal reserves for extreme high-temperature applications. They are used when conventional glass fabrics can no longer withstand the required temperature exposure.
For intensive spatter exposure, specially designed spatter protection blankets are recommended. Key factors include the temperature, size and energy of the impacting particles, as well as the duration of exposure. Heavy, appropriately treated high-temperature or silica fabrics are particularly suitable for heavy weld spatter, slag or molten metal splashes.
Yes. For applications where glass fibres are undesirable, welding blankets made from Preox needle felt, for example, are available. These materials are soft and flexible and are particularly suitable for sensitive surfaces as well as vehicle and automotive applications.
Yes. In addition to roll goods and proven standard sizes, we also manufacture custom welding blankets and spatter protection blankets. Dimensions, edge finishing, fastening options and other fabrication details can be adapted to the respective application.
