Choice of windows

     Pinch you can build, or doing a home renovation, its one of the most important decisions you must make is the choice of frames. The right choice is very important for the appearance of the building indoor comfort, it will largely depend on home heating bills and not least how much it will cost you own windows - the time of purchase and accumulated over the years as a result of its maintenance.
     The option, however, means that you have to make decisions and to be optimal, reliable information is needed. In a country most of bogus products on the market, regardless of price, are in the same category. Some say "buy its Greek windows", others recommend the Turkish, the only argument in both cases is the lowest price.
     The reasonable person knows that retail savings come later too expensive and when you need to make long-term investment costs, the correct solution is to buy from world renowned manufacturers.

     Windows are the eyes of the house - through her come in direct contact with the outside world. Thanks to the design and layout and joinery largely create our sense of comfort affects the functionality of premises and external appearance of the building. When choosing the type of windows and windows must be considered more external noise level, thermal insulation qualities, as well as maintenance.
All this basically puts the classic dilemma: what should be the windows - wooden, plastic (PVC) windows, or so-called aluminum frames (aluminum profiles). Apparently it comes to the design of the windows, and as for the glazing - no discussion. Singles glazed is hurled at the museum construction and in modern homes are exclusively used glass.
     The advantages and disadvantages of each of these three structural material has already been discussed repeatedly. In summary one can say: the tree and wooden windows has very good insulating properties and stability, but unlike aluminum and PVC over time need intensive support. In terms of statics aluminum and aluminum windows has advantage over other materials, but such material is an excellent conductor of heat and despite the measures taken constructive measures heat loss in this type of windows are larger (especially in low-cost structures). Moreover, qualitative aluminum windows with insulated bridges in profiles is the most expensive. The comparative analysis of the advantages and disadvantages shows that the windows of plastic (PVC windows) combine the positive aspects of wood and aluminum windows and largely do not have their negative qualities.
PVC window frames have built-enhancing structural metal profiles, therefore more resistance to buckling and other deformation of the wing not only inferior, but in some cases superior to aluminum. They have excellent thermal insulation properties, resistant to weathering and aging, do not require special maintenance and PVC material gives a wide space and freedom of the designer in designing the shape and profile of the wings.
As with any system, crucial to the quality of the joinery is the material they are made. Preference is given to polyvinyl chloride (PVC), but it is obvious that the buyer can not carry out chemical analyzes and laboratory tests - the only salvation is to buy only products from reputable manufacturers worldwide. This is a guarantee that in time will not regret the petty savings when purchasing windows.
     Profiles of PVC windows are reinforced with various sized and shaped steel reinforced (profiles of square or rectangular cross-section) in height and width. They reinforce the static resistance of the structure, which is especially important in high-rise building. Another advantage of profiles of PVC is the exceptional strength and elasticity of the corners. Homogeneous linkage is done by welding, which we at least did not worsen the aesthetic appearance of the frame. The robust construction and precise dimensions make plastic windows completely impermeable to direct rainwater pouring them against infiltration of outside air through the joints between the wing and the frame.
     If you want yourself to judge the merits of the proposed windows you need to request data for the following indicators reputed manufacturers in the technical passports of their production:
     Heat transfer coefficient - K: Its value determines the ability of the woodwork to conduct heat, respectively, the size of the heat loss. Measured in watts (W) per 1 m2 in one hour at a temperature difference on both sides of the window 1 °.
As this ratio is lower, the smaller will be the heat loss through the window. School is also known that metals are the best conductors of heat.
     Resistance to heavy rain - This indicator determines the extent of protection conferred by the woodwork against the ingress of rainwater. Due to increase the height of buildings increases and the load of torrential rains. Therefore, this indicator windows are conditionally divided into three groups with a view to building height:
-A-For buildings with a height up to 8 m
-In-For buildings up to 20 m
- S - at a height of 100 m
     Coefficient of air permeability of the joints - and - It is measured by the passed amount of air in the joints between the wings and the frame of the frames in different pressure difference on both sides of the frames for a specified period of time.
According to this indicator, it was again placed in three groups according to the height of the building - to 8, 20 or 100 m.
     Strength of corners - It is determined by testing a special bench strength structural damage in its load.
Multi-chamber execution of the framework has extremely high resistance to mechanical stress.
     Soundproofing - dB - This indicator shows the degree of suppression of external noise, especially in a big city makes the occupation of the buildings extremely uncomfortable, reduces efficiency and ultimately permanently harms.
The degree of reduction of the noise level depends mainly on the ability of the glass to absorb sound waves.
The type of windows must comply with the ventilation of premises. In order to limit heat loss from the premises it recommended short but intensive airing of the rooms 3-4 times a day.
     This advantage is of windows which can be opened by rotating around a horizontal axis. Airing is intensely polluted warm air near the ceiling quickly flies out and do not create conditions for intensive and not particularly pleasant for people over the room.

     PVC windows allow the manufacturer to produce windows with the most diverse shape - rectangular, round, arched, triangular, etc. Increasingly used and fram with asymmetrical wings. Modern production technologies allow also the most different and lasting color with a wide palette. All this greatly expands the choices of the architect and the final result will fully depend only on his creative imagination and your taste and preferences.
     As important, however, are the shape and color of the wings, more important is the choice of the most appropriate for a given room and facade overall proportions of the windows. For example, the wing of the wide and low window in the open position will occupy unacceptably large area in the room while heavy glazing will place excessive burdens on the frame and overlaid.
For small spaces such as the appropriate window sizes are 80 x 130 cm.
     Casements are implemented with or without average vertical beam. For single windows nothing is blocking the opening, but in contrast, the load on the frame can pass limits, and even more salty pocket will be buying a big windows, because the likelihood simultaneously break the glass on both wings is too small. Because of all this it is not recommended greater length of the single wing of 150 cm.
As in their implementation without this beam is achieved full width of opening. For reasons of stability, however, windows wider than 150 centimeters is desirable to be satisfied with an average shot. At high structures, most common in old buildings because of the danger of falling cleaning desirable upper window for ventilation to be openable. Advice on proper and stable proportioning of windows to avoid any disturbances or faults in the functioning of the woodwork, you could get from a specialist manufacturing company.
     Not least is the inclusion of external appearance of the building to the environment and the overall architecture of the entire residential kompleks.Prozortsite PVC are suitable for the restoration of old buildings, as different systems profiles provide an excellent opportunity to implement the smallest details and details typical of the last century building styles. For this purpose there are different types of rails separating glass placed inside or glued on it. Developed decorative strips, supporting columns, capitals, balustrades and other elements, repeated the old architecture and returning the authentic spirit of the whole residential complexes.
On the border between the windows and the doors are different sliding doors that separate the room from the conservatory or porch biggest example. In the majority of cases they fill the entire span of the room and the structure is quite complicated.
Bulgarian construction practice almost entirely bypassed sloping front window blinds. This is probably another manifestation of a dismissive attitude towards energy losses because of the west blinds massive. Well executed and quality shutters reduce energy loss through the window by 50%. Besides contributing to energy saving and reduction of penetrating noise, lowered the window blinds in certain cases, especially in the evening improved indoor comfort, isolating them from the environment and curious peek neighbors.
     Modern blinds are made mainly of PVC, they are beautiful, easy to maintain and drive inside. There structures with enhanced protection against intrusion through the windows.
     Although PVC windows is not capricious in terms of maintenance and this activity should not be completely ignored. Each structure contains instructions for cleaning within the appropriate preparations for that purpose, and once a year you can take care of the rubber seal and lubricate hinges and locking mechanism.
Use detergents with cushioned action and cotton cloth.
