aluminum patio doors

Lift-and-slide doors manufactured based on Aluprof’s MB-77HS aluminum profile system are an ideal proposition as a development that connects the interior with the outside environment. They provide a very convenient exit to the balcony, terrace or garden, and moreover, when opened, they do not take up space in the room, which further increases their comfort.

The door can be made in two variants of thermal insulation: ST and HI, and the structure of the profiles allows the manufacture of doors of large dimensions, filled with single- or double-chamber glass. Thanks to its thermal insulation properties and beautiful design, this solution is ideal for both single-family buildings and comfortable apartments or hotels.
