Vertical Sliding Doors
PUERTAS GISMERO vertical sliding doors make an enclosure formed by one or more rigid panels, made of galvanized steel plate and internally of rock wool and a number of gypsum boards depending on the fire resistance required in each case.
These panels have on their sides some pulley systems with bearings that are inserted in the lateral guides fixed to the walls, like a frame, allowing their vertical sliding. The assembly is closed around its perimeter with an intumescent gasket.
The configuration of telescopic sheets is necessary when the lintel is not large enough to house the door on a single sheet.
