Vermiculite paper – Heat-resistant seals & insulation
Vermiculite paper is a fireproof, flexible sealing and insulation material for temperatures up to 1150 °C. It offers a safe and cost-effective alternative to ceramic fibers or silicone seals—it is fiber-free, non-toxic, and formaldehyde-free. Whether for industrial furnaces, boilers, automobiles, or wood-burning stoves, vermiculite paper impresses with its high temperature resistance, flexibility, and ease of processing.

Frequently Asked Questions (FAQ)
Is vermiculite paper safe for health?
Yes, it is fiber-free and non-toxic – safe to use and handle.
Can I cut vermiculite paper myself?
Yes, simply with scissors or a cutter. For precise shapes, CNC cutting is available.
What is the difference compared to ceramic fiber paper?
Ceramic fiber can be harmful to health. Vermiculite paper offers similar temperature resistance but is safer and more moisture-resistant.
