  • The windows are based on profiles produced by a renowned German manufacturer, setting new standards in the field of long life and surface maintenance. They come in an exceptional snow-white color. Glossy profiles made of top-quality PVC are easy to clean and resistant to weather conditions.

  • A wide selection of veneer enables you to provide your windows with individual character and match them with both the facade and the interior. Currently we offer joinery in several dozen colors of both smooth and wood grain finish. The windows are veneered on one side, two sides and in a duo-color formula. Full color veneer is a very interesting solution as well, guaranteeing an aesthetic, accurate finish, and durable color. We veneer windows, fitting grooves, sash edges, and other elements of windows. Full color veneering is available only with wood grain finishes.

  • Multi-Power hardware, or so-called concealed hardware, improves the aesthetics of your windows significantly. It remains hidden in the fitting groove and is invisible when the sash is closed. Moving post rails, drive rods, hinges, and other functional elements can be hidden as well. 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. The hinges provide much higher load capacity and the window shows anti-burglary properties. Windows equipped with concealed hardware are better insulated since it reduces thermal bridges.

  • Aluskin aluminium covers improve the overall appearance of the windows. They allow you to combine the practical advantages of PVC windows with the modern design of aluminium windows. Available in a complete range of RAL colours. We offer a wide range of texture varnish as well. 

  • In our production process, we use top-quality components and ensure following the highest standards. Our machinery enables us to manufacture windows using state of the art technologies such as V-Perfect, an innovative system for joining PVC profiles that makes joints virtually invisible.


  • Safety depends on a number of factors. One of the most important is undoubtedly the appropriate selection of the hardware. To produce Streamline 76, we employ Multi-Matic hardware, the best solution from Maco, a renowned Austrian manufacturer.

  • As standard, the windows are equipped with four anti-burglary bolts per sash, anti-burglary pins with an adjustable clamp, and a device preventing an incorrect handle position. An internal clamp is also a very important element of the system. In addition to ensuring safety, it provides air tightness and easy operation of window sashes as well. We can use WK1 or WK2 class hardware at a customer's request.

  • Reed relays or alarm loops in the pane are recommended for buildings where the risk of a burglary is greater. Reed relays are magnetic movement sensors. In this case even the slightest motion of the circumferential hardware triggers the alarm. The alarm loop is activated after a pane is broken or damaged.

Energy Efficiently:

  • Energy efficient windows with high thermal and acoustic efficiency. Standard Streamline 76 windows provide optimal protection. One-chamber glass package, two gaskets and installation depth of 3" enable the windows to provide an effective barrier for escaping heat. 

  • If you wish to improve the heat comfort, we recommend installing a three-pane package and an insulating spacer. Our insulating spacers provide top efficiency since they are made using special insulating material enhanced with a thin film in order to eliminate penetration of gases and water vapour. The structure of spacersimproves the insulation properties and guarantees long-time air tightness of insulated glass panes and maximum reduction of heat loss.

  • We recommend using Climaplus 4S panes with Streamline 76 system windows. It is a very innovative solution. A Climaplus 4S glass pane lets significantly less solar energy through, enabling you to maintain a pleasant temperature in the interior during summer and reduce costs of air conditioning. In winter it provides a barrier, preventing heat from escaping.
