Plastic windows have undoubted advantages over wooden windows. They effectively use the existing space, look great in almost any interior, and also have a number of properties that make them indispensable in a city apartment. They protect against penetration of dust, moisture and noise into the apartment, and also support the safety of the apartment and at home. For a resident of the metropolis, the window is an opportunity to take a breath, distract from work and familiar things, and focus on the outside world. It’s good when the sun is a sunny landscape, which is pleasant to admire, and it is doubly good when your windows reliably protect you from a raw, dank landscape, which is also not deprived of charms. Plastic windows are thermal protection and noise insulation, which is achieved due to the use of the system of seals and the double-glazed window.
