Alu windows are made of aluminum profiles and thus need additional reinforcement.
They are produced in all options- as one-window frame, two-window frame, sliding, and tilt and slide window. On aluminum windows, as well as on all other windows, blinds, shutters or insect meshes can be added without any limitations.
Choosing a window that has excellent insulation characteristics – you will get energy-efficient windows that will ultimately reduce energy consumption and save money on heating and cooling.
