In the process of picking windows for a home or investment, many important factors should be taken into account. By choosing Bertrand solutions, you can be sure that durability and security are standard, while the rest is a matter of taste and customer preference.


Among the solutions included in our offer is one that combines not only the features already mentioned, but above all modern design with classic. We are talking about Synergic, wood-aluminum windows with an elegant, narrow profile having a hidden sash, which meets with interest and appreciation, among others, of customers from abroad.


The system is dedicated to modern architecture, which is dominated by cubist, angular shapes and maximized areas of glass in buildings, which are designed to perfectly illuminate rooms, provide unobstructed views and allow you to be closer to nature, – emphasizes Olaf Bertrand, director of marketing and export at Bertrand. – It is most often chosen by customers building new homes, who appreciate the aforementioned modernity, but still consider wood one of the best materials in connection with its durability, appearance, natural character and its rigidity, which allows the creation of structures of considerable dimensions. In Synergic windows, the wood is visible only from the inside of the building. We can give it a suitable opaque color as in the case of aluminum windows, the texture of brushed wood, varnish it in azure or transparent color, which emphasizes the beauty of natural wood. The aluminum overlay, on the other hand, ensures that the windows are resistant for years, and do not require any special type of maintenance. Its color scheme, too, can be customized in the entire range of RAL, Tiger or NCS colors.



Synergic owes its aesthetics to a larger glass area than competing wood-aluminum windows. This is made possible by the extremely low folding of the frame and sash, which has a total of 90 mm, which means that they are as much as 33% lower than in other wood-aluminum windows. In addition, the Synergic system, due to the hidden sash from the outside, allows the window frames to be built up almost completely. In this case, only the glass and any bars are visible, which, due to the hidden sash, windows opened from the outside look the same as fix windows. The customer himself decides how he would like to install the windows, and the extent to which the frame will be visible from the outside depends on this. With Synergic windows, the maximum amount of light can enter the room, and on top of that, the amount of natural heat in the room is increased.


The technology is also characterized by such aspects as exceptional durability and security (burglary resistance of RC2 class), achieved thanks to the advanced method of gluing glass packages in combination with special hardware. They affect not only the resistance of the structure, but also thermal qualities, aesthetics, comfort of use or ease of care. Durability, on the other hand, is translated into window frames made of wood with a thickness of 90 mm and an aluminum overlay that provides protection against weather conditions (the highest class of watertightness, air permeability wind resistance).



We can use really large window panes in this technology, and we can also make HS Panorama wood-aluminum lift-and-slide doors dedicated to it,– emphasizes Olaf Bertrand. – They feature fixed-field glazing in the frame, with the glass surface starting practically from the threshold. HS Panorama also has a much narrower mullion than standard wood-aluminum HST doors.
