Colours can emphasise the shape of aluminium joinery and provide it with individual character and genuine appearance.

All aluminium systems offered by our company are available in two colour palettes – RAL and DECORAL. We supply anodised windows and doors as well. Such a large selection enables you to choose the perfect windows to match both the interior and the façade.


Basic colour palette. Profiles come in one of 213 smooth colours or in sand or metallic texture.


Woodgrain finish palette. Aluminium joinery offered by our company comes in the following colours: golden oak, rustic oak, bog oak, ebony, walnut, walnut vein, mahogany, sapele, pine, fir, beech, cherry, wenge, winchester, sweet cherry, dark sweet cherry, chestnut.


Anodised aluminium provides excellent properties (hardness and resistance to corrosion) and allows you to choose from among a wide variety of colours.

The Ferroline system is largely intended for the renovation of historical buildings. The appearance of window sections perfectly imitates vintage steel joinery, while the design provides excellent performance. The system enables the production of all types of in-swung windows (side-hung, tilt, and tilt-and-turn), openable windows, and non-openable windows. Excellent thermal performance comes along with splendid sound insulation, water and air tightness, and high durability.

The profile shapes are available in several versions. The renovation frames allow for the installation of new windows without the removal of the original jambs, which otherwise might damage the wall around the opening. The sight surface of aluminium profiles has been adjusted to minimize the design differences between the original, historic windows and the new products. Based on proven solutions and featuring a comprehensive range of new profiles with the right forms, Ferroline is the way to make windows which will perfectly match your building project.
