Having decided to install windows, the consumer, of course, first of all asks the question of choosing a profile. After all, this is what will be seen from the outside and will create an aesthetic appearance for the window. However, a profile is not only about external aesthetics. Window properties such as noise and heat insulation, frost resistance, strength and durability of the window depend on the profile..
The modern market for plastic windows offers the buyer up to twenty varieties of window profiles. But it is quite difficult for a non-professional to understand the intricacies of each of them. First, let’s highlight 2 main types of profiles. The main profile is one that has a strength function. It is part of the window openings. The add-on profile does not carry such a function. So, let’s figure out the selection criteria.
Colour.90% of buyers choose white. This is probably due to the fact that white is a traditional color for windows and is suitable for almost any interior. White windows are versatile and carry a tinge of severity and purity. When choosing a white window, pay attention to its shades. Some manufacturers have pure white windows, others are grayish, and in some cases yellowish. Carefully inspect the surface of the profile itself: it should not be rough and in no case should there be any scratches or other damage on it. A rough surface is difficult to care for and it ages quickly. Maybe you decide to choose a different color? In this case, coordinate it with your interior and apartment design..
Width.Whereas previously all profiles were of standard width, today you have a choice. In addition to standard sizes, a wide profile of the window structure can be ordered. The size of the standard profile is 58–62, while the extended profile is 70–72. The wide profile allows you to install the so-called five-chamber glass unit, the width of the profile significantly affects the thickness of the window. The wider the profile, the higher its sound and heat insulating functions. Wide-profile constructions are considered “business-class” windows, narrow ones are included in economy-class.
Thickness.Modern Russian building codes in accordance with GOST distinguish two types of profiles in thickness. These are class A, which is thicker, about 3 mm thick, and class B, which is half a millimeter thinner. Class A is more resistant to cold weather. If you choose according to our temperatures, then A is the best option. Class B profiles are designed for warmer climates.
Reinforcing profile thickness.This figure should be approximately 1.5 mm. Allowed, of course, and 1.2 mm, but taking into account the fact that you do not have too high windows. The strength of the structure depends on the thickness of the reinforcing material. If it is too low, then the profile can be skewed or jammed. The reinforcing profile of the optimum size ensures that the structure remains intact. After all, a defect may appear when the warranty period has already expired, and then you will have to correct window defects from your budget.
