The rock wool sectional door Mineral-Secc® is a door instended to operate in places having high temperatures, where the polyurethane panels are not appropiate or where polyurethane is not allowed. Thanks to its characteristics it can be used as flame-arrester door.
This model consists on an internal aluminium structure, filled with rock wool and covered on both sides with lacquered steel sheet; and it is compensated by springs having the same lifting and operating system that a standard sectional door has.
Please, consult for sizes.
