MSEA 1+2 OPENABLE WOOD-ALUMINIUM WINDOW

An openable wood-aluminium MSEA window is the most common type of window, suited for both new construction and renovation sites. This double sash inward opening window is a good solution for both detached houses and blocks of flats.

Wood-aluminium windows are popular today because they are in practice maintenance-free. The frame and inner sash of wood-aluminium windows are wood. The outer sash is entirely aluminium and the exterior parts of the frame have aluminium profile casing. Although wood-aluminium windows are maintenance-free, exterior aluminium parts as well as interior wood surfaces should be inspected regularly and possible maintenance measures taken.
