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. 

One system, multiple possibilities. Without using elements of any other systems, we are able to produce windowsdoorswindows with a concealed sash, and even Despiro doors. This multipurpose solution guarantees top aesthetics and durability. The two-component central gasket provides excellent air tightness and thermal insulation of the space between sash and frame.

The effective appearance of MB-86 doors and windows is guaranteed by a wide range of available colours (RAL and woodgrain palette) and glazing strips, available in three versions: Standard, Prestige, and Style. If you are looking for unique solutions, we recommend duo-colour varnishing, two different colours on the inner and outer side of the profile.

A wide range of glazing possibilities is also worth noting. MB-86 windows may be produced with panes up to 58.5 mm thick (frame) and 67.5 mm (sash), allowing you to install a two-chamber, acoustic, and anti-burglary glass package.

MB-86 windows can be additionally equipped with concealed hardware. 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-86 system belongs to products of excellent thermal insulation parameters. The profile structures enables three variants. Depending on the thermal insulation requirements, these can be ST, SI and AERO. AERO profiles are filled with aerogel, material of excellent thermal insulation properties.

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.

Doors and windows based on MB-86 system meets the highest requirements for thermal insulationair permeability, and water impermeability. They are also resistant to wind load. Recommended for energy efficient construction.

Installing new aluminium windows without removing old frames? It is possible! We provide very functional renovation windows using the MB-86 system. The windows are based on standard profiles, to which an angle bracket is fixed (on one or both sides). Renovation fins are inserted into the bracket in order to mask old frames. Installing new aluminium windows does not require removing old frames, minimising the risk of damaging the façade and time needed to install new windows.


  • frame depth (door/window): 77 mm,
  • leaf/sash depth (door/window): 77/86 mm,
  • glazing depth (window): frame 13.5-58.5 mm,
  • glazing depth (door): 13.5-58.5 mm,
  • renovation fin, length: 45, 65, 85, 105 and 115 mm,
  • internal masking profile, length: 20, 40, 60 mm.

Accessories can remarkably affect the appearance and safety of use. Aluminium profiles are often use for very large glazed areas. These, however, can be very tempting for burglars. To protect yourself against them, we recommend equipping MB-86 windows with reed relays.

You can also install VSG glass panes, i.e. safety glass. This type of glass is manufactured by bonding the pane with special film. Such structure provides the window with anti-burglary properties (hard to break), such windows may act as structural elements since even when broken, glass adheres to the film.

Ventilators ensure continuous flow of fresh air into the room. We recommend pane-mounted Renson ventilators and humidity-sensitive ventilators offered by our company. Pane-mounted ventilators are installed between the profile and the pane, while humidity-sensitive ones are included within the frame. The frame height must be consider since not all frames enable you to install a humidity-sensitive ventilator.


Apart from standard solutions, MB-60 system joinery is available with varnished handles and concealed hardware. You can also choose to install internal and adhesive sash bars (25 mm wide).

Aluminium widows are popular with those who wish to have large glazed areas and open spaces. Such glazing is very attractive, however, it may cause rooms to overheat. To prevent overheating, 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.
