Aluminium Window - Decalu 110 Steel


What makes the joinery unique and gives it an individual look is undoubtedly its colour. Thanks to the colour you can perfectly match colour of elevation to the colour of the interior. The more so because the windows can be varnished to a uniform colour, but also in the bicolour formula, which means that the window can have different colour from the outside and inside.

All aluminium systems from our offer are available in two colour palettes – RAL and DECORAL. We also offer adonised joinery.


Basic colour palette. Profiles can take one of 213 smooth colours or colours with sanded and metallic structure.
