Sectional door Mineral-Secc® is a door to improve thermal and acoustic insulation between the exterior and interior place where the door is located, thanks to the rock wool filling on the inside with low thermal and acoustic transmittance.
It is a door intended to operate in places where the polyurethane panels are not appropriate or are not allowed for safety. Thanks to its characteristics it can be used as flame-arrester door. It is also ideal for insulating outside loading docks.
The 40 mm panels are made up of two sheets of white galvanized steel or fireproof fiberboard, filled inside with rock wool. It has fireproof reinforcements throughout the entire panel, joined together with an aluminium male/female.
The panels are raised by means of lateral guides and their weight is compensated by a spring system.
