Which plastic windows are better to install: subtleties of choosing window designs + five best manufacturers

Are you planning to replace old faulty windows with new double-glazed windows, are you wondering which plastic windows are best to install and are looking for a suitable option? Agree that when choosing plastic windows, buyers often pay attention to such criteria as methods of opening frames, care requirements, warranty obligations and cost. And important operational properties fade into the background.

Isn’t it true that such an approach cannot be called competent? When choosing the right plastic window unit for your home or apartment, you need to take into account a number of significant technical characteristics and installation conditions.

We will help you sort out this issue, consider the parameters that need to be taken into account when choosing which windows are best to choose to ensure safety and comfort in your home, and also present the TOP 5 best manufacturers. Here's a video guide to help you with recommendations on choosing the right plastic window unit.

Important window selection criteria

Unlike wooden products, a plastic window does not require regular painting, has improved sound insulation characteristics, lasts longer and prevents conditions that reduce heat loss.However, you should carefully choose PVC windows in the store.

On the one hand, the design contains a lot of technical aspects, but on the other hand, you can come across a dishonest seller who wants to make money from a buyer who is poorly versed in the matter.

Selecting the “right” plastic window is a rather important undertaking, because it is assumed that it will serve properly for 35-40 years of opening

So, when choosing a suitable plastic window unit for your apartment, you need to consider:

• the quality of the glass unit and the number of air chambers in the profile;
• thickness and overall width of PVC profile walls;
• presence/absence of reinforcement;
• quality level of seals and fittings;
• opening mechanism.

Any of the listed criteria affects the final cost of the product. In addition, buying an expensive block with a massive 3-chamber double-glazed window is not always advisable. When choosing, you should proceed from the climatic and weather conditions of the location of the building.

In addition, it is worth thinking about how you will clean windows from dust and dirt.

Quality properties of windows

The basis of any design of plastic window blocks is a PVC profile. According to the standards, primary or recycled (secondary) polymer is used in the production of the material.

The first type is considered high quality; in the second version, various additives and plasticizers are added to the plastic so that the product meets all the requirements for impact and strength characteristics.

The profile used for the production of windows is made from PVC granules using the technological method of continuous extrusion on automated lines

It is not possible to distinguish between a profile made from primary or secondary PVC on your own. Their appearance is completely identical.

In this case, you need to study the certificates provided by the manufacturer and rely on their honesty.

Number of air chambers

Inside, the profile structure is made hollow and divided by vertical partitions into several parts filled with air. The more such segments, the higher the thermal insulation qualities of the double-glazed window and the minimum heat loss.

The smallest number of such cameras is two. In accordance with Russian climatic conditions, windows with 3, 4 and 5 chamber profiles are most often produced.

For residents of large cities, in addition to the number of air chambers, characteristics related to noise insulation are of great importance

The increased number of air chambers contributes to an increase in the price of a window unit. However, the more vertical sections inside, the more massive and thicker the profile.

If, due to the large area of ​​the window opening, the sash turns out to be high and wide, then initially it is better to choose a window with a 5-chamber frame.

Profile width and thickness

The width of the window profile is determined by the number of vertical chambers. The greater their number, the more plastic partitions inside, and the wider the PVC profile. Its width is also influenced by the dimensions of the chambers and the presence/absence of reinforcement inside.

The usual profile width is in the range of 58-90 mm. If it is thinner, it will not be able to withstand a double-glazed window. And options are more widely used, mainly at industrial facilities or in the construction of winter gardens.

A profile width of 70 mm guarantees plastic double-glazed windows improved heat and sound insulation qualities, which contributes to a comfortable indoor microclimate

In accordance with GOST, a plastic window frame lasts at least 20 years. The thicker the walls, the more reliable and durable the frame structure.

According to European regulations and standards, plastic profiles are divided into 3 classes by thickness with the following markings:

• “A” - at least 2.8 mm thick;
• “B” - thickness not less than 2.5 mm;
• “C” is a parameter set by the manufacturer.

It is most preferable to choose a class “A” profile, the thickness of which is more than 3 mm. The window sash made from it is least susceptible to sagging and distortion.

When choosing option “C”, you need to be careful: window units made of thin-walled profiles (less than 2.5 mm) are recommended to be installed only in non-residential premises.

Availability of reinforced insert

To make the profile more durable, a reinforcing liner is equipped in the middle intermediate chamber. It is made of galvanized steel that can withstand corrosion and mechanical stress. The thickness of the reinforcing liner in the profile should be within 1.2-2 mm.

It is well known that plastic has a low elasticity and durability, so a reinforcing insert is used to give it additional rigidity and ensure the safety of the profile

In cross-section, the shape of the reinforcing profile can be any. The closed version has more increased rigidity than the U-shaped open version. However, the more metal, the heavier the window block is.

When choosing a window with a reinforced insert, you should take into account the rise to the apartment and the installation of the structure.Excessive heaviness will affect not only the strength of the product, but also its final cost.

Selecting a suitable seal

The next most important parameter when choosing a PVC window is the seal used on the sash profile. The window unit will not last long if the sealing insert is installed of poor quality from the very beginning.

In a few years, drafts will appear in the house, and you will have to call a professional or replace it yourself.

The properties of the seal are as follows:

• sound insulation and tightness of the shutter cover;
• thermal insulation, no drafts;
• protection of rotary and locking fittings from moisture and dust

If at the store you are confused about what color sealant is better to buy: black or colored, we recommend choosing the first option.

This advice is based on the fact that a black tint is natural for natural rubber, while colored rubber contains dyes that can impair the service life of the material.

A special elastic cord serves as a sealant. It is fixed quite simply into the grooves specially left on the profile. With proper use, the seal can last about 10 years, maintaining its original quality characteristics.

For windows, as a rule, 4 main types of sealing gaskets are used, made from:

• TPE (thermoelastopolymer);
• silicone rubber;
• rubber;
• EPDM (artificial ethylene propylene rubber).

The seals used in the production of window blocks may differ in material, cross-sectional shape and color. The qualitative characteristics of some are more resistant to abrasion, others to frost, and others to delamination and deformation during prolonged use.

Selection of window fittings

When choosing the best plastic window for your apartment or house, you should pay special attention to the fittings.

It affects not only the convenience of opening and closing window sashes, but also the durability and reliability of the structure.

In order for the window structure to last as long as possible, it is necessary to carefully select not only the window structure, but also correctly determine which fittings are best and suit your purposes.

Plastic window blocks are distinguished by the large weight of the sashes, especially when using 2-chamber double-glazed windows. The fittings must withstand significant loads.

Traditional fittings are designed for a maximum weight of 50 to 130 kg, which is quite enough for windows in apartments and houses.

The main details of window fittings are as follows:

• lower and upper swing-out configuration;
• frame opening and rotation limiters;
• handles with locking mechanism;
• locks with key if additionally required;
• loops with a reinforcing effect;
• slot direction ventilators;
• strike plates for the lock and trunnion.

All these important fittings must be manufactured by reputable companies. Saving on this is not recommended.

The fittings are always under a certain load, and if you save money and install a cheap option, the window unit will not be able to serve the required period.

Window opening mechanism

The types of opening window structures are quite diverse, which makes it possible to use the window in any interior, making it as functional and practical as possible. Most window sashes usually open indoors.

Manufacturers offer several standard types of opening plastic windows, which can be:

• rotary;
• tilt and turn;
• sliding;
• parallel-sliding.

All these varieties depend on the installed fittings and design. PVC windows acquire these configurations in ventilation mode when equipped with the necessary high-quality fittings.

Manufacturers of PVC windows provide them with a special opening mechanism, which allows you to open the profile completely or for ventilation mode. To connect these 2 methods, a tilt-and-turn mechanism is equipped

Typically, it is the fittings that determine the type of opening, which, in accordance with the thermophysical properties of double-glazed windows and profiles, forms the totality of their performance qualities and the final price.
