LEIAB is situated in Mariannelund, Sweden, and is one of the market's leading manufacturers of inward opening windows in timber clad aluminium - side hung windows, tilt/turn windows, fixed windows, sliding doors and French doors and is the clear leader within the niche of inward opening windows.

The harsh demands of the Scandinavian climate have contributed to the development of what we believe to be the perfect window - the LEIAB window. These developments have placed LEIAB in the forefront within the inward opening window niche. Combining that unique warm and cosy feeling that only wooden windows can give, together with the distinctive permanence of shape and maintenance-free quality of the outer aluminium, the LEIAB composite-window system fulfils both the aesthetical and the practical needs of property owners.
