double hung window charlotte North Carolina

PVC windows have recently appeared on the market, the cavities of which are not filled with air, but are filled with foamed heat insulators - expanded polystyrene, for example, or filled with fiberglass materials. Even with a relatively small number of chambers, their thermal insulation characteristics are much higher than air ones. But for now, their price is also higher.

Plastic windows do not surprise anyone now, they are installed almost everywhere - from shops and offices to luxury apartments and three-story mansions. But their quality is completely different. If at the beginning of their “biography” plastic windows were exotic structures that looked like a degraded version of serial wooden ones, as they say, “soviet”, and practically equaled them in quality, then at a price they clearly went into the premium segment. But in the process of technological development, they have turned into a completely competitive tovary, which has a number of unique properties.

There are no completely low-quality windows on the market now - there are a lot of companies offering windows of their own production and only one-day firms can afford to work with cheap materials. Before ordering windows, you need to find out as much as possible about the company's reputation, see its products, etc. It is best to buy products from large manufacturers - high-quality equipment plays a lot in the manufacture of windows. Many small companies and workshops cannot afford to buy expensive cars, and therefore their products are somewhat worse.

Replacing a double-glazed window with an energy-saving one Why choose KORSA Windows? The main requirements for the windows of apartment buildings are high noise insulation, safety and the possibility of ventilation of the premises. An important factor is the choice of components. Their quality affects the tightness of the doors and the operation of the fittings. Residents of the lower floors should choose plastic windows equipped with protective elements. If small children live in the apartment, it is necessary to have blocking elements from the inside.

But in slightly more extreme circumstances, such as severe frost or heat, as well as direct sunlight (UV), it can fail. Becoming brittle in the cold and softening in the heat, it quickly becomes unusable if the window sash is actively used. But with the doors constantly closed (or constantly ajar, in micro-ventilation mode, for example), it will last quite a long time.

You can choose a package by marking - SPO - single-chamber, and SPD - two-chamber. Some manufacturers offer three and four chamber packages, but they turn out to be too heavy and expensive, while reducing thermal conductivity is not very noticeable. There are other ways to reduce energy losses without increasing the number of cameras.

How to determine the quality of the profile The first thing you need to pay attention to when buying windows is the appearance of the plastic. If the window is not laminated with decorative wood-like film, then the type of material will tell you a lot. High-quality polyvinyl chloride is a monolithic material, completely smooth, uniform in color. If spots are visible on it, or, worse, small or large grains, this is a fake, which is not worth buying in any case.

The quality of the product is guaranteed by the reputation of the manufacturer. Among the cult types of fittings are products of the following brands: MACO (Austria) - high protection against premature wear and corrosion due to wax and anti-corrosion spraying Winkhauz. Represented by a wide range of rotary, sliding, combined systems, handles, locking devices, hidden elements; ROTO (Germany) - zinc coating is used for corrosion protection. High load capacity (sashes can withstand a weight of about 150 kg), a wide range of designer handles, locking systems, opening modules, etc.; REZE. (Turkey). Docking system of connections for convenience of installation. Burglary resistance. Aesthetic appearance. Recommended for completing windows installed in rooms with high humidity.

Given the characteristics of glass as a material with a certain rigidity, spatial structures like double-glazed windows are distinguished by certain size restrictions. They can be within a minimum of 300mm on one side and in an aspect ratio of 5:1. But the maximum glazing area should not exceed 3 m2 in a single-chamber package with 4 mm thick glass and 4.2 m2 with 5 mm glass thickness.
