No one needs to be persuaded that metal-plastic windows are a necessary and economical thing. Millions of people installed them in their private homes or apartments, and appreciated the benefits of replacing old and cracked insulating glass with new and beautiful products. But the fact is that the market is filled with different quality products. What do you need to pay attention to when you come to a company engaged in assembling and assembling windows?
What are the metal-plastic windows?
- Which profile should I choose for windows ? Evaluate the appearance of the quality of the profile is a rather difficult task. To pursue brands may not be necessary, but the big cheapness should also alert the potential buyer. On a small and deafened window, almost any 3 or 5 chamber profile is suitable. But if you want to replace the window with a height of one and a half meters and a width of 75 cm, here it is better not to use any lighter versions. Do not you want them to curl an ugly arc? This rule also applies to the doors to a balcony or terrace . In Europe, there is a law prohibiting the use of new structures with a wall thickness of less than 3 mm.
- Reinforcement . Metal hard frame saves plastic windows from deformation. According to the rules, the thickness of the amplifier should not be thinner than 1.4 mm, but you can not see it visually. It is best to compare, if there is such an opportunity, the weight of samples from different manufacturers. Quality windows will be heavier. It has also been observed that thick reinforcement is usually not used in thin-walled products. There is one more clue how to choose high-quality plastic windows - pay attention to the appearance of the outer surface. Expensive samples are distinguished by glossy and beautiful plastic, which also often helps to distinguish them from second-class crafts.
- Sealant . For their production use rubber, rubber, silicone, various types of rubber. It is inserted from both sides of the glass and is responsible for the tightness of the product. The welded seals can not be changed, but they are hard to insert, but can be replaced. There are windows with removable rubber bands (EPDM), made of thermopolymers. At them the service life is almost equal to the service life of the window itself - up to 20 years.
- Double-glazed windows . If it is a question of glazing a cold and not heated balcony, then it may make sense to put single-chamber simple packages. But in an apartment house, such a product completely sweats and creates a lot of inconvenience to the owners. It is desirable to put energy-saving windows, with a glass thickness of 4 mm or more.
- Fittings . It is impossible even to calculate how much you will close during the entire operation and open the window. Therefore, these parts must be of only high quality. Well, when the window allows you to use a slot vent, there is a reliable stop limiter, protection against burglary, microventilating.
Errors when choosing plastic windows
- We usually choose plastic windows, focusing on the brand of a quality profile manufacturer, but in addition to this element there are many other nuances. It is important to consider the fact who collects the window. You can make a marriage when assembling or use an expensive brand profile and fill
its cheap materials. - In the case, how to choose the right plastic windows, you need to pay attention to the documentation. Sometimes the warranty extends only to the profile, and the whole window itself is not protected by a certificate.
Plastic windows are products that have to serve for decades. Not always cheapness leads to savings, and with metal-plastic windows the same picture. Fittings, gaskets, glass , plastic in many people very quickly fail. Therefore, the question of how to choose good plastic windows is, albeit not the most difficult, but quite a responsible one.
