isoTHERM®
Optimum processing and careful selection of our raw materials ensure that isoTHERM® by Frenzelit shines with consistently high properties.
Our high-temperature-resistant technical fibers pave the way for modern thermal and acoustic insulation. For decades we have been driving the development of new finishing techniques and material properties.
Application temperature limit 750 °C (short peaks up to 800 °C)
These green-colored textured special glass-based products are extremely textile even at high temperatures. isoTHERM® 800 is characterized by its high temperature and chemical resistance and is harmless to health.
- Filament diameter 6-13 μm
- Incombustible (in accordance with DIN 4102)
- Loss on ignition < 3%
- SBG approval for all woven fabrics
Note: Temperature exposure leads to color loss. However, this does not affect temperature resistance!<br/> isoTHERM® 800 CG is the name of our needlemat product line.

Application temperature limit 850 °C (short peaks up to 1000 °C)
The products have a light blue color. Chemically treated E-glass is the base material. The components that melt at a low temperature are eliminated from the E-glass fibers in the process, which increases temperature resistance. isoTHERM® 1000 is extremely textile and very skin friendly. The products are also harmless to health.
- Filament diameter 6 μm - 9 μm
- Incombustible (fire class A1 woven fabric approval according to DIN 4102)
Note: Temperature exposure leads to color loss. This does not affect temperature resistance!
