Wood-aluminium windows.

GS-Centurio is a special system with a so-called hidden sash. The effect is identical to that of fixed glazing. It represents a very attractive form of modern construction, characterised by simple and clean architectural lines. 

The system meets the insulation criteria, the measured value of the heat transfer coefficient (Uw) is certified from Uw = 0.717 W/[m2K]. 

GS- 200 is a system designed for those who prefer a traditional pragmatic solution. It is the most popular system with classic AL profiles. From a design point of view, it has the most possibilities of all aluminium types. The heat transfer coefficient (Uw) is certified to a value from Uw = 0.735 W/[m2K]. 

GS-300 is a system with sharp profile edges. It is suitable for both contemporary and modern architecture and wherever concrete, steel or glass is used. The individuality is emphasised by the fact that the profiles of the GS-300 system do not have a chamfered edge and the profile surfaces form a right angle. The measured value of the heat transfer coefficient (Uw) is certified as Uw = 0.731 W/[m2K].

GS-400 is a system typical for its sharp edged profiles, similar to the GS-300 system. The surface of the sash is flush with the frame, creating a uniform space. At the same time, the special shape of the aluminium sash shifts the glass 15 mm towards the outer edge, allowing the use of thicker triple glazing. The individuality of the system is emphasised by the fact that the profiles of the GS-300 system do not have a chamfered edge and the surfaces of the profile form a right angle.

GS-500 is a system in which the outer edge of the frame and sash are moulded. GS-500 offers another aesthetic option for the external architectural appearance. The measured value of the heat transfer coefficient (Uw) is certified as Uw = 0.731 W/[m2K].
