When it comes to the replacement or glazing of the balcony, the question will be asked about the choice between wooden and plastic. Both those and others possess positive and negative qualities. What are the pros and cons of plastic windows?
Reliability and ease of use gained great popularity.
Advantages of plastic
Plastic heating and comfortable in operation.
The correct installation (according to GOST) depends on the accuracy of the measurements produced. The opening should be measured not only with outdoor, but also from the inside to determine the depth of a quarter of the opening.
True, durability depends on the choice of high-quality profile and the good faith of the manufacturer: Do not choose the cheapest products. The cost may not be less than $ 40 per m², with the minimum configuration itself. Manufacturers usually promise that the designs of the PVC profile and the glass package are designed for half a century of operation, but in reality this period is noticeably less. All the same, after a few years, change the sealing elements, replace the fittings. But it is not necessary to redo the frames every year, as you have to do with wooden windows.
Hermetically closed PVC flaps provide excellent noise insulation. Of course, even with the closed slacks, the sounds from the street will still be coming to the apartment, but they will completely become completely quiet. You can also not be afraid of dust and leakage during the rain. If the windows overlook the noisy route with a large number of transport, it makes sense to order structures consisting of small fragments and from glass of different thicknesses, it will help repay resonant oscillations. But this glazing will cost more.
The adjustment unit (sealing) with the use of waterproofing (psul), thermal insulation (mounting tape) and vaporizolation.
You can order any configuration. With vertical and horizontal opening, with or without a window, divided into two halves or whole - as the soul wishes and wallet will allow. For glazing the balcony, it is advisable to order such, in which at least two sash opens. For areas in which winter is enough, a two-chamber glass package is sufficient for good thermal insulation.

PVC windows weigh less than in wooden frames. With a large glazing area on the removal balcony, it has a considerable meaning. Mosquito nets are easily attached to plastic, and just as easily removed.
Plastic has high fire safety compared to wood. Special substances are introduced into plastic - antipyrenes that do not support burning. In addition, PVC frames do not twist, do not block, do not rot.
About shortcomings
I can not pay attention to non-environmental statements. Lead, who used to be part of PVC, is no longer used more in production, zinc or less toxic cadmium is added instead. Wooden frames can be far less environmentally friendly: first, they are often painted, soaked for greater moisture resistance and fire resistance. And secondly, wood is consumed to produce wood, that is, forests are cut down. So in terms of environmental friendliness plastic will easily give odds to the tree.
Two-chamber glass windows are more efficient than a single-chamber reduces heat loss, increases sound insulation, but disrupts the air exchange rooms.
From real deficiencies, a significant coefficient of temperature expansion of plastic can be taken into account. This means that plastic is larger than the tree, expands at high temperatures in summer and shrinks cold in winter. Over time, this leads to the need to replace the sealing elements, as the design ceases to ensure tightness when closing.
Tightness, by the way, can also be not quite convenient quality. Hermetically closed sash interfere with natural air and moisture exchange. If it does not register regularly, the humidity can increase in it. Exit - air conditioning or regular ventilation.
Another lack of plastic - it cannot be repaired. If a scratch, crack or dent appeared, then you can only eliminate them. More plastic accumulate static electricity, because of what dust attracts them. But this problem is solved if used to leave a means with antistatic.

What conclusion can be done by comparing the pros and cons? What advantages if not much more, then they are much more significant than several minuses. Durability and ease of use with relatively low cost - an excellent argument in favor of installing PVC.
