All windows and the sliding uplifting window doors can be externally coated with aluminium.
A special aluminium painting method allows to obtain an optic effect, which makes these windows look like the traditional wooden windows.
The window body remains unaltered, and an extra system for fitting the frame makes sure, that also the performance of aluminium- coated windows will remain the same.

It must be underlined, that most coloured aluminium frame covers, have corner joints welded inside in order to guarantee a perfect form - keeping over the years. This accounts for a better look of the finished product and for corners naturally protected by the paint.
The peculiar anchorage system enables the frame cover to follow the natural moves of wood. The distance between the aluminium frame and the window itself ensures a correct ventilation and preserves the wood from rotting. This obviously makes windows live longer.

The frame cover can be removed in a simple way to undergo special maintenance.
