Modern window systems conquer hearts not only with their super aesthetic appearance. This is also an excellent technical specification, thanks to which you will feel comfortable behind the combined window structures. Do you crave to learn the whole truth about the windows of the NEXT generation?

Enhance the security functions of windows
The main function of the windows of an apartment or house is to protect it from external atmospheric influences. Therefore, various materials, from which window frames are made, are to some extent subject to negative influence.
Undoubtedly, each material used for the manufacture of windows has advantages and disadvantages. Attempts to combine the best qualities and merits of materials have found application in the construction of combined windows. Agree that the best way to extend the service life of the wooden window will be a protective leaf made of metal or plastic. Thus, new combinations appear to create strong windows.
Taking on these positive qualities, and combining the constructive opportunities, the manufacturers of combined windows have achieved good results. The only thing that bothers with the large-scale application of this type of windows is the relatively high price of the design.
Possible combinations
Combined windows are an advantageous combination of these materials:
• wood + aluminum
• wood + plastic
• plastic + aluminum.
The most common and affordable in the price segment is the combination of wood and aluminum. In this construction of the windows, the heat-insulating properties of natural wood are combined with the excellent protective characteristics of the aluminum elements. The use of a combined aluminum window tree is justifiable for installation in the case where maintenance of wooden structures is difficult or practically unavailable. For this, the protection of the wooden profile is carried out in several ways.
For single-frame systems, equipped with wooden elements, a reliable part can be considered an aluminum shell, fixed by mechanical clamps.
For the protection of double-frame windows use the same elements as for single-frame ones. The window system in this case consists of two windows: internal (wooden) and external (aluminum).
To begin with, in order to experience, feel and analyze the advantages and disadvantages of a tree of aluminum windows, it is necessary to understand the classification of combined window designs.
To compare the parameters, consider:
• wooden window, type IV -68
• wood aluminum window, type MEXG-90
• wood-plastic-aluminum BUG-Alutechnik
• alumino-wooden window type A16D.
wooden window
Classic window wooden single-leaf type IV - 68 "German window" made of laminated veneer lumber, besides stylish design, it has good heat and sound insulation. Aluminum here and does not smell, except that as a drain on the bottom of the leaf. However, there are certain shortcomings that cause suspicion when choosing a wooden window.
This is a low climate resistance, sometimes leading to significant costs for operating the window. In addition, there is a violation of geometric stability under long-term moisture conditions. The combination of these shortcomings leads to the fact that at one point a wooden window will have to say goodbye. The conclusion suggests itself - to change the existing system to a combined wood aluminum window.
wood aluminum windows
Unlike a simple wooden euro window, the outer part of the aluminum window tree is aluminum. The bearing part of the window structure is a tree. The outer layer of aluminum duplicates the paint layer of the tree, not realizing the strength characteristics in full. There are two types of wood aluminum blocks (DAB): single-leaf and with two separate doors.
For example, consider a tree aluminum window type MEXG - 90 "Finnish window". This type of windows is the most practical, thanks to one leaf, equipped with a double-glazed window. Aluminum for the model is used as a hinged protective element. The quality of thermal insulation and noise insulation is good, which, however, does not prevent this type from being the leader in its price segment. The problem lies elsewhere, namely, in geometrical stability, strength in the corner parts and additional manufacturing of structures of considerable size. By the way, the price for wood aluminum windows can be called democratic.
The choice of aluminum window tree is shown here.
wood-plastic windows
The design of the wood-plastic window system type VUG-Alutechnic is a combination of three parts: an aluminum outer part, a middle part of plastic and an inner part of wood.
And we note that the plastic is not a box design, but rather performs the functions of a thermal bridge. It would seem an excellent solution for a combined window. But there are problems with strength, because in the section of the system there is too much plastic and so little aluminum. Therefore, according to thermo-technical parameters and criteria, the wood-plastic window clearly loses both wooden and wood to aluminum windows. In addition, the fixing of parts in the corners of the structure can not be called reliable.
And, finally, a successful alliance of style and reliability are alumo-wood windows.
aluminum-wood windows
Aluminum-wood windows type A16D are the most popular combination of a "warm" aluminum profile. Structurally, the profile of aluminum wood windows is lined with wood from the side of the room. And, it is noteworthy that for cladding use massive wooden elements, and not veneer.
Wooden elements perfectly cope with the assigned isolating functions - heat and no noise. In addition, the presence of the aluminum profile gives the system tremendous strength, for comparison with windows made of wood, PVC and wood-aluminum structures.
For the production of aluminum-wood windows mixall use thermostatic bridges - special rips. In a single thermo-insulating chamber, a thermostatic bridge made of reinforced polyamide with low thermal conductivity is technologically integrated inside the profile.
Such a bridge prevents the penetration of cold air through the aluminum profile. Another bridge is designed to prevent the formation of condensation between two materials with different thermal conductivity. The second thermo-insulating chamber is placed between the aluminum profile and the wooden part of the structure.
The connection of aluminum and wooden elements is carried out by plastic clips. Thus, the new profile system combines excellent performance and reliable proven materials. As a result - a fantastic coefficient of thermal conductivity Uw 0,75 W / m²K and no less fantastic price. Therefore, when asked by the grandson: "Grandfather, what are the combined windows?" - you can always give an exhaustive answer.
