Protection from cold and wind: warm plastic windows

There aren’t many improvements that compare to warm plastic windows when it comes to keeping your house cozy and warm. These windows are made to protect your house from the elements, including wind and cold, in addition to improving its aesthetic appeal. Warm plastic windows provide better insulation than traditional windows, which are more likely to let in drafts and lose heat.

Warm plastic windows are generally composed of materials with superior thermal properties, such as vinyl or uPVC (unplasticized polyvinyl chloride). They provide as a barrier against external temperatures because they are made up of several layers. By keeping your house cooler in the summer and lessening the need for continuous heating in the winter, this insulation contributes to the stability of the indoor climate.

The ability of warm plastic windows to stop heat transfer is one of their main advantages. They do this by using cutting-edge building methods and low-temperature-bridging materials. As a result, your home’s internal warmth is retained and outside cold air is kept at bay, increasing energy efficiency and lowering heating expenses.

What kind of design is this?

Energy-efficient PVC windows have a design that keeps the cold out in the winter and lessens heat loss from the space. Generally speaking, a design is deemed energy-efficient if it has glass with a special reflective coating and an inert gas, like argon, filled in the space between them.

These adjustments help the room cool down more slowly by reducing the transmission capacity of infrared radiation released by heating appliances. Such a coating keeps the house from overheating in the summer by reducing the amount of solar energy that penetrates.

For instance, 90% of infrared radiation passes through typical double-glazed windows, but windows with a special coating can retain up to 90% of this thermal energy indoors by reflecting it back. Furthermore, sound insulation is greatly enhanced when combined with gas filling the chambers. If the walls are thick enough and wide enough, heat-saving window installation is typically possible in practically any living area. You should compute the load if you intend to install such a structure in a frame building because energy-saving windows are heavier.

Additionally, it is not advised to install some of these structures on the sunny side because the low-emission coating can quickly lose its effectiveness, reducing the structure’s service life to just ten years.

Varieties

There are differences between energy-efficient windows in terms of construction style, glass coating, and interior chamber filling.

By type of design

The number of chambers between the panes is typically the only design difference between warm PVC windows. Two glasses and one camera is the least expensive option; the marking 4-16-4-16Ar-4i is the best option in terms of weight and energy savings.

This indicates that there is argon filled in the space between the three 4 mm thick glasses that make up the window. Moreover, glass with a low-emissivity coating, which reflects heat back into the space, is indicated by the 4i marking.

Energy saving double glazing

Energy-efficient double-glazed windows can be categorized into three primary subtypes based on the type of glass used:

1. K-glass (hard coating) was one of the first to appear and reduced heat loss by 30%. It differs from ordinary glass in that during the production process a special coating of indium and tin oxides is applied. This film increases the strength of the finished product, but for greater protection this coating is additionally hardened and laminated. Emission factor is 0.2. Lately this option has hardly been used.
2. I-glass (soft cover) is warmer than the previous version. Its emission factor is 0.04. It is made by depositing a layer of silver and titanium oxide by cathode sputtering. The main disadvantage of such a coating is its low resistance to atmospheric and physical influences, which is why it requires sealing (in its absence, the protective layer very quickly loses its protective properties). If rainbow stains appear on the surface of the glass, this means that it is defective and does not have the appropriate protective properties. To prevent oxidation of the applied layer, the space between the glasses is additionally filled with inert gases.
3. IM subtype is a combination of several technologies and the newest of all previous options. It is created by applying three layers to the glass:
4. bottom and top of oxides and nitrites, which determines how much light will pass through, as well as what color the final product will be;
5. the middle layer is most often soft (consists of silver or chromium), which is why it has properties similar to the i-version (reflects infrared rays);
6. to prevent damage to the middle layer, a protective coating (shockproof) is used.

When IM glass is used in conjunction with the i-option during the summer, the sun’s rays absorb much less heat, keeping the room cool. Similarly, during the heating season, infrared radiation from heating appliances is reflected back into the house, minimizing heat loss.

The characteristics of tinted and self-cleaning optional IM glass are similar to those of tinted products; however, radiation is absorbed using the same principle as light filters rather than being blocked as with closed curtains.

By type of void filling

Three different types of gas are used to fill the empty space between the panes in thermal insulation windows rather than dried air, which has a thermal conductivity of up to 0.030 W / m2 *°C.

1. Argon. Is one of the most common types of insulation in warm PVC windows, since it has a lower thermal conductivity than air, but is cheaper than xenon and krypton. After filling a single-chamber glass unit, it improves its thermal insulation to the level of a double-chamber with an air gap. Also reduces the passage of solar flux by 15% and improves noise insulation. Estimated service life is up to 8 years, since in some cases the gas gradually evaporates. Density is 1.8 kg / m3, and thermal conductivity up to 0.015 W/m2*°C.
2. Krypton – this is a more expensive analogue for filling empty chambers in a double-glazed window. It improves sound insulation by 30% more than argon, and thermal protection is increased by 2.5 times compared to an air gap. Service life – up to 25 years, but depending on the climate it may change. Due to its properties, it allows you to reduce the used space inside the double-glazed window, which reduces the overall thickness and weight of the window. This effect also allows you to make thermally efficient windows that will withstand the most severe frosts, since by reducing the distance between the glasses, you can increase the number of air chambers and layers of glass. At the same time, the final width of the PVC window does not increase too much. The density of the substance is 3.7 kg/m3, and the thermal conductivity is up to 0.010 W/m2*°WITH.
3. Xenon has properties similar to krypton, but its thermal insulation properties are 5-10% worse. Service life is up to 25 years, and the cost is higher than argon. Xenon density is 5.9 kg/m3, and thermal conductivity is up to 0.011 W/m2*°WITH.

Warm profile

The idea of a warm profile works better with aluminum windows because they have a unique partition that keeps cold bridges from forming between two exterior metal components. Since the plastic profile is made of polymer and the reinforcement is not in contact with the outside world, it is initially heated.

However, the number of internal air chambers determines the design’s thermal efficiency. Products with 5-8 air cells can be classified as "warm" varieties of PVC profiles.

Requirements

Specifications for low-emissivity coated glass as stated in:

They list every feature such a product ought to have in addition to the different kinds of flaws and whether or not they are acceptable during production.

For instance, standard 4 mm thick glass should have a light transmittance of no less than 0.86, and the emission coefficient (heat retention) can range from 0.025 to 0.1110 depending on the energy-saving class.

Furthermore, there shouldn’t be any chips, scratches, or areas where the coating is missing on the glass. GOST 30673-2013 specifies requirements for PVC profiles, and GOST 24866-2014 specifies requirements for windows that are filled with gas.

Installation features

Installing warm PVC windows is similar to installing conventional PVC windows. The primary distinction is that you have to pay close attention to where the reflective surface and glass unit are located. The insulating layer must be facing the room and the soft I-covering must be placed inside the air chamber.

Products coated in IM are installed as external glass because they reflect sunlight, and products coated in I are installed as middle or internal glass (on the room side) because they must retain heat.

Two methods exist for argon filling a glass unit:

• using a special valve, which can be seen on the surface of the dividing frame;
• at the factory, using industrial equipment in sealed chambers.

There aren’t many differences between the procedure for setting up and using warm PVC windows and that of conventional products.

In this instance, the choice of fastener is crucial because energy-efficient designs may employ concealed hinges or a better seal.

Advantages and disadvantages

Among the advantages of warm plastic windows are:

• improvement of the microclimate in summer and winter;
• reduction in heating costs;
• an increase in temperature near the window, which reduces the likelihood of condensation and subsequently fungus;
• weight reduction due to increased energy efficiency (a single-chamber warm window corresponds to a regular 2-chamber window);
• reducing the wear rate of fittings by reducing the weight of the sashes;
• protection against fading of the surface of furniture or household devices, since when using IM glass the amount of direct sunlight is reduced (part of the radiation is filtered or extinguished);
• improvement of sound insulation properties;
• protects plants from ultraviolet radiation and freezing, which allows you to place them on the windowsill even in winter without fear that they will be damaged.

Among the drawbacks, it is important to mention:

1. higher cost than conventional PVC windows (although over time this pays off due to savings on heating);
2. rapid loss of the insulating qualities of the coating if you install the window in a place with prolonged exposure to sunlight;
3. some types of warm glazing are not suitable for installation in single-chamber structures.

Installing warm plastic windows is an efficient way to keep your home warm in colder climates and prevent drafts. These contemporary windows offer better insulation against wind and cold in addition to improving the visual appeal of your house. Warm plastic windows lower energy costs and contribute to year-round indoor comfort by keeping heat inside and keeping out drafts. This article explains the advantages of warm plastic windows, how they keep your house warm, and why they are a wise investment for any remodeling project that aims to increase comfort and energy efficiency.

Average prices

The type of coating, number of chambers, and gas type used in energy-saving windows all affect their average cost.

Standard double glazing costs 1050 RUR/m2 with one camera and i-protection, and 1500 RUR/m2 with two voids.

A single-chamber product that includes IM and i protection and argon filling for voids costs 2500 RUR/m2, while a two-chamber product costs 4000 RUR/m2.

Is it possible to convert it from a regular one??

It is possible to make an ordinary window energy-efficient, but doing so will typically only result in a 15%–30% increase in energy efficiency.

You can carry out this process by swapping out double-glazed windows for heat-insulating ones. Since it might not line up with a typical double-glazed window, the most important thing is to compute and measure the required width and weight.

In certain situations, the glass can be covered with a unique heat-reflecting film. It is easier to select to fit the intended parameters of the room because it is available in transparent or tinted options. It is not necessary to disassemble the window entirely to make this improvement because it is just glued to the exterior of the glass unit.

Investing in warm plastic windows is crucial to keeping your house cozy throughout the winter. They lessen the quantity of heat lost through the windows and offer superior insulation against the cold. This implies that even in extremely cold weather, your house stays warm and comfortable.

These windows provide efficient wind protection in addition to keeping heat inside. Their construction keeps drafts out and improves the general comfort of your living areas with tight seals and strong materials.
