ALUPROF folding doors with a thermal partition represent a modern construction created at the request of investors and architects. Folding doors are available in the MB-59S, MB-60, MB-70, and MB-59S Casement systems, allowing doors to open outwards.
The folding doors offer various depths of section construction, depending on the system (from 50 mm for the frame, from 59 mm for the sash). If you decide on the MB-59S and MB-59S Casement, the depth amounts to 70 mm, and for MB-70 it is 79 mm. The heat transfer coefficient also depends on the selected system.
The profiles are connected via minimal machining using the supplied aluminium connectors and accessories. Type L-joint is cut at a 45-degree angle and then crimped/pinned and glued to the aluminium corners extending into the inner chambers of the profiles. By using glue, the joints are tight and solid. T-joints are made by studding the lacings with the extended connectors with glue.
Swing, glazing, and central gaskets are available in EPDM - synthetic rubber. Ventilation and drainage openings (the external side) are protected with covers.
