High-quality metal-plastic window and door structures are a guarantee of warmth and comfort in your home
Plastic windows – components
Thanks to modern technologies metal-plastic windows are made from reinforced PVC profile, double-glazed windows with one or two chambers and special fittings.
Frames and sashes are made from PVC profile. The internal configuration of profile systems differs in the number of air chambers (from 3 to 6) and geometry. Also, an important quality factor is the profile width. The more chambers and mounting width manufacturers indicate, the warmer the window is considered.
For the strength of the entire window structure, mandatory reinforcement of the profile is performed.
Double-glazed windows provide the main function of any window – light transmission. They are fixed in the frame and sash with plastic glazing beads with sealing rubber. A double-glazed window with two air chambers, formed by three panes and two spacer frames, is considered standard. Recently, due to their low cost, single-chamber double-glazed windows have become widespread. But they are less effective in terms of home heat conservation.
Window fittings are a complex engineering mechanism responsible for the functioning of sashes, their opening and tilting. They are made of high-strength stainless steel that withstands serious loads. The window handle is just a lever to set all internal parts in motion.
The components of plastic window structures can safely include plastic window sills and metal drip caps.
Choosing a plastic window for glazing
Any structure must be evaluated as a whole. And if we choose plastic windows price here depends primarily on the components: profile, fittings, and double-glazed window.
The most suitable plastic window for an apartment is a structure assembled from a five-chamber REHAU profile with tilt-and-turn fittings, equipped with a two-chamber double-glazed window 36 mm thick.
For summer cottages, windows from a three-chamber profile system with installed single-chamber double-glazed windows of 26-30 mm are quite suitable.
For cottages, it is customary to install windows from the widest profiles, which have six internal chambers. The double-glazed windows must match the profile in physical properties. Therefore, for such windows, double-glazed windows with a thickness of more than 42 mm are used.
Anti-burglary fittings are a good addition for plastic windows in private houses.
The main thing is to choose a reliable manufacturer
Selection of components for new windows is very important. But the main thing still is the choice of the manufacturer who makes and installs the structure. Even from the best components, if non-professionals work, you can get a crooked, non-airtight window with a bunch of defects.
Installation is a crucial stage on which the service life and technical condition of the window fully depend. With poor-quality installation, wind can blow through the windows and installation seams, and icicles can grow.
Before replacing windows, professionals will definitely check the ventilation in the room. After all, if it works poorly, the double-glazed windows will inevitably fog up.
