Types and features of plastic windows: the pros and cons, how to choose

When it is necessary to replace the windows, plastic models are often installed. This is noticeable if you pay attention to high-rise windows. Quality wooden windows are much more expensive. They are installed rarely, usually in private houses and cottages. The frames of plastic windows are made of PVC material with a metal base and double-glazed windows. Consider the types of plastic windows, their pros and cons. What to pay attention to before buying.

Types of plastic windows

Materials and manufacturing technology allows the production of plastic windows with a different number of sashes. This depends on the size of the window. Standardly make from 1 to 3 sashes.

Type of opening:

• Deaf windows - do not open. They are usually installed in private houses or in buildings where you can wash the windows from the outside without any problems. They are suitable for corridors, utility rooms. Their advantage is that they retain heat well.
• Swinging - the window opens into the room. Minus - the open sash interferes, it is especially not convenient on a cramped loggia or balcony.
• Swivel sash opens on a vertical axis away from the room. It is located along the window, so it does not interfere. This is the most modern type of design, suitable for tight spaces.
• Tilt sashes tilt at the top toward the room, becoming in airing mode. This function is combined in the pivoting type of sashes.

Often combine a deaf sash with a tilt-and-turn sash. Then the construction is stronger and warmer. The sash should be such a width that it was convenient to clean it.

Pros and cons

Pros:

• Durability - a quality plastic window serves more than 10 years.
• The material does not deteriorate from precipitation. Over time, you may have to replace only the sealing rubber.
• High air tightness. Plastic windows have a summer and winter mode, when the clamping sash loosens or strengthens.
• Minimal maintenance - wiping from dust as needed is enough. No need to paint.
• They look stylish and modern.
• The color is not only white. There are brown models, you can find different colored frames.

Minuses:

• Because of the high tightness there can be a greenhouse effect. It is necessary to ventilate often or arrange high-quality ventilation.
• Scratches and damage to the frames are not restorable.
• PVC is an electrostatic material, it can attract dust.

How to choose

Pay attention to such characteristics:

• Profile width - in northern regions, it is desirable that it is 70 mm, in the south - 60 mm. The wider the profile, the more insulating glass chambers can be placed there. The more massive is the frame, the more reliable are reinforcing layers.
• The number of insulating glass units is at least 2. The more (3, 4, 5), the higher the heat and sound insulation. There could be additional coatings on the glass to improve energy efficiency.
• Depends on the quality of fittings depends on the ease of use of the window: smooth running handle and sash, no jamming.
• The sealing rubber is the most hermetic if three loops are installed.

It is desirable to choose a frame with a glossy surface. Dust gets clogged in the irregularities of the matte profile, and it is difficult to remove it. Also, if necessary, look whether there are additional functions, such as micro ventilation. These are small gaps that can open and close. Then fresh air comes in, but the room doesn't cool down quickly.
