MB-59S Casement Folding door opening outward

This folding door system with thermal break is a modern design by ALUPROF S.A. that fulfills the wishes and requirements of our customers: architects, investors and business partners.

The outward opening folding door structure can be designed using the following window and door systems: MB-59S, MB-60, MB-70, while the MB-59S Casement system allows to make folding doors opening outwards.

The structural depth of the sections depends on the selected system and ranges from: 50 mm (frame), 59 mm (casement) under the MB-59S system and MB-59S Casement up to: 70 mm and 79 mm respective under the MB-70 system. The value of the heat transfer coefficient and sound insulation also depends on the aluminum system used. Due to appropriate profile design and the use of machining templates, folding doors are characterized by very simple and quick prefabrication. Frame and sash sections have profiled grooves of such dimensions that they can be used with circumferential hardware and connectors compliant with the EURO standard. Proven Roto hardware is used in folding doors. The rail of these hardware can be mounted on the upper profile of the frame (Top hung) or at the threshold (Bottom hung). In the individual systems you can choose between different variants of thresholds and ways of their installation. Profile joints are made with minimum treatment, using the supplied aluminum joints and additional accessories. The "L"-type corner joints are made by cutting the ends of frame or leaf profiles at 45° and crimping or studding and gluing them (using a 2-component CORALGLUE® ) to aluminum corners slipped into the internal chambers of the profiles. The use of glue guarantees high stiffness and tightness of the connection, while the corners allow to keep the perpendicularity of the connected profiles. Transverse joints of "T" type are made by studding lacings with slipped connectors and using CORALGLUE® glue. Glazing, cover and central gaskets are made of EPDM synthetic rubber. Most gaskets are installed continuously, without cutting at the corners, joining the ends of the gasket in half the length of the upper crossbar. This method of glazing ensures outstanding water and air tightness performance. The central gaskets are cut at 45° and glued in the corners, or at 90° and glued to the rubber corner.

Each outdoor building structure must have an effective system for draining water and ventilation of the glazing chamber and the chamber between the sash and frame. The ventilation and drainage holes on the outside are covered with plastic covers.
