Which windows to choose: wooden or plastic?
Those who have acquired a new home or decided to overhaul an old one invariably have questions about windows. Which windows are better for a private house – wooden or plastic? And in a city apartment? And these questions are by no means rhetorical. Both those and other designs have their advantages and disadvantages. Today we will conduct a small comparative analysis to make it easier for you to make an informed choice between plastic and wood.
What is the difference in the device of plastic and wooden windows?
The main element of any window is the frame. What are the differences in the structure of plastic and wooden frames?
The frames of plastic windows are made of synthetic polymer – polyvinyl chloride (PVC). The blanks for them are PVC profiles cut into parts of the required size, which are hermetically welded together to form a frame. Inside, the PVC profile is divided by partitions into several (from 3 to 8) chambers – hollow sections independent from each other. The more cameras, the higher the noise and heat insulation of the window. A reinforcing steel liner is inserted inside the middle, largest chamber, which gives the frame additional rigidity and protects it from deformation.
But these are plastic windows, to which everyone has long been accustomed and which do not surprise anyone. And what are wooden ones? Of course, we are not talking about “carpentry”, which was widespread in our country in Soviet times, but about high-quality (and expensive) products. Externally, modern wooden windows look almost the same as plastic ones. And in terms of their durability, noise and heat insulation, they are not inferior to PVC windows. Since wooden windows with double-glazed windows originally came to us from Europe, they are often called euro-windows.
In the production of wooden window frames, not solid wood is used, but glued beams. Why are there such difficulties? Surely, many of you have come across a situation when in the summer period the window sashes do not close well, in winter, on the contrary, between the same sashes there are gaping gaps of serious size.
The use of laminated veneer lumber technology eliminates the problem of contraction / expansion of the material as a result of temperature fluctuations. In terms of its elasticity, glued laminated timber is comparable to a reinforced PVC profile. Wooden blanks for frames must be impregnated with special compounds that protect wood from fungus, rot, insects, the negative effects of moisture and sunlight, after which they are primed and varnished. Double-glazed windows in wooden windows are used exclusively with two chambers.
Have you forgotten the old Soviet windows, the huge gaps in which every year with the onset of cold weather it was necessary to seal up in order to at least slightly reduce heat loss? With the advent of modern plastic and wooden windows, we got rid of this problem, but acquired another. The cracks in the “carpentry” brought us a lot of trouble, but they provided a constant flow of fresh air. Data source: деревянные евроокна (russian).
Hermetically sealed modern windows tightly “clog up” the room, preventing air exchange, as a result of which the humidity rises inside, and people experience a lack of oxygen. Let’s try to figure out which window is better in this regard – to buy wooden windows or plastic ones?
Polyvinyl chloride is a material that is absolutely impervious to air. To prevent air stagnation in the room where plastic windows are installed, regular forced ventilation is required. An alternative is to install a ventilation valve on the window, which ensures the flow of fresh air even when the shutters are closed.
