Ferlajoint is made of E Glass, VHTC or HT Glass yarn interlaced around a core made of card sliver made of C or VHTC glass or E, VHTC or HT glass yarns.

Its essential technical advantages include its lightness, deformability, and excellent thermal insulation capacity. As it is silicon-coated, it prevents the release of fibres and ensures an excellent seal and ideal handling

Its main applications include:

- Door seals (fireplace inserts, ovens and boilers)

- Mould gaskets

- Various thermal protection covering materials.

The high temperature glass used resists very high temperatures (softening point of carded HT glass is 1,000 °C) and allows this product to be used in a wide variety of applications.
