The VLITEX fire blanket SUPERIOR is made of high-quality silica glass fiber fabric that has been specially developed for use in extreme temperatures. On contact with intense heat, such as that generated by a burning vehicle, the silica fiber reacts by contracting strongly. This thermal reaction impairs the structure and effectiveness of the blanket, which is why it should not be used again after a fire.
For maximum safety and efficiency, we recommend one-time use to ensure that the blanket fulfills its full protective function.
