When the task is to glaze an apartment or house, many are interested in which double-glazed windows and profiles are the warmest. OKNO.RU specialists will help you understand this difficult issue. A high level of thermal insulation of windows is especially important with panoramic glazing. Despite the large area of glass filling, a large floor-to-ceiling window should reliably protect the room from the cold. You will learn which plastic windows are the warmest from this article.
How many chambers does a warm double-glazed window have?
To find out which glass bags are the warmest, you need to look at the intimacy of the product. Two hermetically connected glasses make up the chamber of the glass bag. Between the glass sheets there is an air gap, a spacer frame. The width of the chamber affects the thermal and sound insulation of the glazing. The larger it is, the warmer the window. When purchasing, check the thickness of the glass. Even in one chamber there can be glass of different thicknesses - 4, 6, 8 mm.
A two-chamber system is usually able to provide warmth and silence in the house, provided that a high-quality profile is used and proper installation is used. For greater noise protection, the outer chamber must be made wider than the inner one. The three-chamber glass package is much warmer. But it weighs more, needs reinforcement of the base, and a wide opening. Its installation is justified in regions where the street temperature in winter reaches minus 45 degrees. Thus, for maximum thermal protection, it is better to install three-chamber double-glazed windows if the base for them is strong enough.

Peculiarities
Windows with heated translucent elements are distinguished by the following design, technological and functional features :
The profile, as well as the translucent block of the window structure, is supplied with a heating cable connected to the power network through a step-down transformer.- Conductor busbars are installed along the entire perimeter of the glass.
- A sensor is integrated into the electrical circuit, which is responsible for sending a signal when a short circuit occurs, which helps to automatically open the wiring.
- The translucent product is covered with a metallized coating, which will significantly reduce the emission of thermal energy.
- A technological gap is formed between the window frame profile and the glass unit, intended for laying the heating cable.
Important. It should be noted that, despite the low electricity consumption, these window units are energy-dependent products and require an outlet or cable wiring with the integration of a separate machine in a common apartment or house panel.

Recommendations from our installers
According to the experience of our craftsmen, plastic windows with multifunctional double-glazed windows are optimal for residential premises. As research by leading experts in Europe has shown, the warmest PVC window is REHAU GENEO with an energy-saving three-chamber double-glazed window filled with inert gas.
Rehau Geneo is a leader among energy efficiency profiles. Its six chambers are formed by RAUFIPRO fiber fiber. It is used without reinforcement.
Three advantages of REHAU Geneo:
- 6 profile chambers with installation depth 86 mm.
- Three seals guarantee the tightness of the glazing.
- The RAUFIPRO material is not reinforced with steel, which eliminates the appearance of cold bridges.
Among the glass packages, the Super Comfort model (4і-16Аг-4-16Аг-4і) from GLAS TROESCH is the warmest for today. It insulates heat with a coefficient of 1.75 m2K/W. The system has 2 chambers, the space between the glass is enlarged and filled with argon.
How to Change Insulation Using Window Hardware
There are several ways to improve thermal insulation parameters. First of all, in order to perform their functions well, roof windows must be correctly installed on the roof slope. It is best to insulate them with thermal insulation material to reduce the risk of thermal bridges.
The insulating material must be protected on the outside with a vapor-permeable film, and on the inside with a vapor-proof film. To increase the thermal insulation of roof windows, you can even use a sealing clamp in the thermal version.
A collar with additional thermal insulation is an excellent system solution that guarantees a tight and “warm” connection between the window and the roof surface. This allows them to be insulated above the level of the strip. It has elastic insulating material glued to the inside, which fits tightly to the window frame, thanks to which it forms thermal insulation after installation. The thermoflange thermally insulates frames and significantly improves the heat transfer coefficient by up to 15% depending on its type.
Another way to improve thermal insulation is by installing interior and exterior accessories. Internal blinds offer limited protection against heat loss in winter. Installing external blinds or awnings is a cost-effective solution. These accessories already significantly increase the energy efficiency of roof windows. Awnings are also often mounted on facades. Their main advantage is protecting the interior from heating on hot days. In winter, they increase energy efficiency by up to 16%, protecting the house from heat loss.
Warm windows must be installed in such a way that thermal bridges do not form when they come into contact with the wall. This is done by sliding them into a layer of insulation.

What is provided in the warmest windows for an apartment
- Thermal insulating spacer frame . A standard hollow aluminum frame creates a cold bridge and causes condensation to form along the edge of the window. The warm analogue of Glas Trösch ACS+ reduces heat loss to zero. With it, condensation does not appear from the edge of the glass unit; here the surface is much warmer.
- Krypton is denser than argon. Its molecules are larger and its viscosity is higher. Therefore, double-glazed windows filled with krypton are warmer and quieter. They reduce costs for air conditioning and heating, and reliably block street noise. Condensation on a double-glazed window with krypton almost does not form. The system transmits light well and is environmentally friendly.
Where to use heated windows?
Window systems equipped with electrical heating have a wide range of applications. Most often, this technology is used for glazing:
Buildings with standard and panoramic windows, country houses, balconies, terraces, loggias. They can be used as a heater if it gets very cold in spring or summer.
Attic, which is used as a full floor for a living room or a creative workshop.
Skylights and glass roofs.
Swimming pools - in conditions of high humidity, the glass will not become covered with condensation.
Winter garden, greenhouse, greenhouse. With the help of heated windows, you can provide a suitable microclimate and level of lighting for plants.
Offices, business centers, commercial premises.
Such glazing is indispensable in conditions of high humidity; water droplets do not form on it, as well as for rooms with inclined or horizontally located windows.
Before choosing the type of glazing, you can consult with managers and order a cost estimate. It depends on the area of the system and the technical characteristics of the equipment.
Which plastic window is the warmest for an apartment or house?
If the most important characteristic of glazing for you is thermal insulation, your ideal window consists of the following elements:
