As for the external side of the profile, it is always made of plastic. The metal frame makes the window structure more durable and stable. High strength is especially necessary in harsh operating conditions – for example, on the upper floors of high-rise buildings. Technologies are actively developing, which leads to increased reliability of window structures. Along with this, there is a gradual reduction in the cost of such products on the market, which has a positive effect on demand. In essence, it is proposed to buy PVC windows, but with broader operational capabilities.
The main material for metal-plastic windows is polyvinyl chloride, and outwardly such windows are practically no different from ordinary plastic ones. PVC is a synthetic polymer that has long been used in various fields of human activity. The main advantage of PVC over natural material is the ability to regulate the necessary parameters of the substance during manufacturing. PVC is not subject to corrosion, practically does not wear out, is inert to atmospheric influences and is absolutely safe in terms of ecology. Due to high plasticity, it becomes possible to manufacture windows of any shape and size.
The average service life of metal-plastic windows is about 20 years. It is possible to select windows for a specific interior. If we compare products made of PVC and wood, the range of the former is more diverse in shape. It is possible to manufacture rectangular, arched, lancet, round windows. Colors, sizes and design features are very diverse.
Another important advantage that distinguishes metal-plastic windows on the market is good thermal and sound insulation, since all joints at the connection points are sealed.
There are no problems with the care of such windows. Any detergents are allowed if they do not contain abrasive elements or solvents. PVC windows do not need to be painted or sealed for the winter. Several options for opening sashes in different planes are provided, which creates additional convenience during operation.
