Differences and features
The goal pursued by consumers justifies the money spent, provided that the installer provided a quality product. The replacement of old windows with new ones is undertaken to minimize the penetration of dust and moisture, reliable sound insulation, prevent heat loss and save on heating bills. Therefore, experts advise to pay attention to:
- the number of chambers, air and double-glazed windows (3 and 4 chambers are an excellent option for residential premises, a larger number is justified in harsh climatic conditions);
- profile wall thickness in mm, variable for external and internal partitions (they are determined by belonging to class A (2.5-2.8) or B (2-2.5 mm);
- installation depth (normal operation at 58-70 mm, minimum value -50 mm);
- type of glass (float, colored float or triplex, laminated, coated with a special protective layer), selective, k-glass, tempered or reinforced;
- sealant - rubber, ethylene propylene rubber, thermoplastic elastomer, silicone;
- ventilation mode - micro-slit ventilation, window, combs or valves.
Even if some criterion seems preferable, it will not hurt to clarify its characteristics. For example, valves in this market segment offer automatic and mechanical, overhead and rebate types, with variable capacity.
Add-ons
The method of adjusting ventilation, automatic or manual, is not the most cardinal of the selection criteria. Much more important is the correct way to open the window structure, because the manufacturer has different offers - from the usual swivel and hinged, to combined and even sliding, intended for installation in problem areas. Window fittings are a vulnerable part of the system, therefore special attention is paid to its quality: only handles are removable, anti-burglary and with a lock, and there are many hinges, locks and locks, and they are different in quality and reliability.
