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 following colours of anodised elements are available: blasted silver, blasted gold, blasted inox, blasted champagne, blasted olive, blasted brown, blasted black, brushed anodised inox, brushed strong anodised inox. 

MB-104 Passive windows meet the highest thermal insulation requirements, which is confirmed by certificates issued by the Passive House Institute in Darmstadt.

The system combines technical possibilities, excellent thermal protection and great appearance. MB-104 Passive joinery is made of three-chamber profiles, the central part of which acts as an insulating chamber (60 or 61 mm wide). Available in two versions (SI and AERO) depending on the required thermal insulation. In the latter case, the space between thermal breaks is filled with aerogel inserts. Both solutions enable us to guarantee excellent heat transfer coefficient.

If you really value thermal comfort, we recommend insulating spacers. Made of complex insulating material, they improve insulation properties and reduce the risk of temporary condensation of water vapour. Moreover, they guarantee long-time air tightness of insulated glass panes and minimisation of heat loss by reducing the thermal bridge at the profile-pane joint.

Thanks to a special shape of the two-component central gasket, pane gaskets and hopper gaskets, the windows provide excellent resistance to water penetration and wind load.

A large amount of glazing is typical for modern buildings. However, if windows and doors are to serve their function properly, top quality materials must be used.

MB-104 Passive system combines great technical possibilities with excellent thermal protection, at the same time improving the overall appearance of the building. The profile depth is adjusted so that the sash and frame form a uniform plane on the outside. You can install varnished handles matching the colour of the window and concealed hardware in order to improve the appearance. It remains hidden in the fitting groove and is invisible when the sash is closed. All elements of the hardware may be concealed. Apart from their aesthetic values, such hardware has some practical advantages as well. It allows the user to adjust the sash in three dimensions and set the sash opening width.

MB-104 Passive joinery comes in any colour from RAL and woodgrain palettes. We recommend a painting technique known as powder coating. This varnishing technology guarantees excellent appearance and provides aluminium with additional properties such as resistance to corrosion and UV radiation.

If you want to provide your doors and windows with even more unique appearance, you can choose your colour from DECORAL palette. Woodgrain finishes enable you to combine the noble appearance of wood with modern technology and advantages of aluminium.

Accessories can significantly affect the functionality and aesthetics of joinery. We offer a wide range of accessories such as handles, pull handles, transom closers.

When aesthetics is an important factor, we recommend varnished window handles. Available in the colour of the window, they improve the overall appearance of the composition. VSG laminated safety glass ensures safety of use. Additionally, we recommend installing reed relays, essential components of the alarm system. Reed relays are magnetic sensors that trigger the alarm when the position of the circumferential hardware is changed, i.e. every time when somebody tries to open the window.

Ventilators improve the overall feeling of comfort in the room. MB-45 system joinery can be equipped with Renson pane-mounted ventilators.

For large-area glazing, we recommend screen-type outer roller blinds, one of the most stylish ways to protect the premises against excessive heating. The material from which they are made absorbs and reflects a large part of the sunlight, enabling the user to maintain a comfortable temperature inside the building. The roller blinds are available with an aluminium guide, wire guide, or an aluminium guide with a ZIP system. The material is a combination of glass fibre and PVC.
