It is important to ensure the proper installation of the double glazed window to optimize the window’s energy performance. The tightness and the perfect integration of the window into the frame are essential conditions to take full advantage of the advantages of double glazing. Calling a professional for installing or replacing your windows is recommended as long as you are not a handyman.
A standard double glazed window is made up of two panes separated by an air or gas layer. Excellent thermal and sound insulation, the installation of double glazing optimizes the comfort of a home and its thermal performance. Today, it is equipment that has become essential, both for windows and doors, to the detriment of simple glazing.
Let’s the important point checks that must be considered while installing the double glazed windows.
- At first, decide what you want- merely changing the glass pane or the entire window.
Before choosing a double-glazed window, an important question arises. Do you just want to replace the window, i.e., the moving and glass parts of the window, or just the frame (fixed frame)? Both options are possible. We know that energy savings depend on the openings and that the good condition of the tire is very important. Note that if you choose to replace the blades only, you will lose the surface of the glass and, therefore, the brightness. Double glazing has a frame added to an existing frame. Before choosing a specific solution, it is advisable to contact an expert who knows how to assess the quality of the framework and give the best possible advice.
- Types of double glazing for windows
Depending on the needs, it is possible to opt to install a double glazed window with specific characteristics.
- The double glazed argon gas window: The air space is replaced by argon gas which increases the insulating performance of the double glazing.
- The krypton gas double glazed window: Rarer than argon, krypton has more or less the same insulating capacities, but it is more expensive.
- Double-glazed window with reinforced insulation: One of the glazings is covered with a film of metal oxides. The insulation capacity is 1.5 times greater compared to standard double glazing.
- The burglar-proof double-glazed window: More robust, it is made of laminated (or tempered) glass which has undergone a special treatment. This type of double glazing ensures great resistance in the event of an intrusion attempt.
- The heated, double-glazed window: It is intended for homes located in cool regions. It has a transparent layer whose role is to return heat through a phenomenon of radiation.
- The types of carpentry for a double glazed window
There are mainly 3 materials, which are the most common in window joinery:
- Double glazed wood window
- Double glazed PVC window
- Double glazed aluminum window
No matter what type of carpentry you choose, the sound and heat insulation will be roughly the same. Wood, PVC, aluminum, the material are to be chosen according to the architecture of the house, the desired aesthetics, and the price.
- Consider Double glazed window price and weight.
The price of a double glazed window varies widely. Depending on the models or the surface, the price changes a lot. This is why you should never buy double glazing without first consulting several professionals. Each carpenter you consult will establish a quote for the installation of double-glazed windows, which will allow you to compare later.
Apart from price, weight is one of the main criteria for selecting double glazing. If it is intended to be installed over a large opening, be aware that masonry reinforcement work may be necessary. Above all, keep in mind that requesting multiple quotes is recommended regardless of the work planned. To do this, you must start on a common basis in order to make the comparison between the offers and the prices.
- Insulation and soundproofing
The performance of a double glazed window lies in its ability to insulate the house at the level of the openings and thus prevent any loss of heat. Exterior noise is also reduced.
Four indicators define the performance of a double glazed window.
- U g coefficient Indicates the performance of the thermal insulation of the glazing. The ideal ug value is between 1.2 and 1.5 W / (m².K)
- Uw coefficient Indicates the thermal transmission coefficient of the entire window (glazing + joinery). The ideal UW value is between 1.2 and 1.5 W / (m².K)
- Sw means Solar factor of double glazing. It defines the ability of the window to transmit heat. Sw Between 0.30 and 0.40 is ideal.
- TLw is a Light transmission factor that defines the ability of the window to pass light. Between 50 and 60% of TLw value is ideal.
In addition to thermal insulation, double glazing can benefit from more efficient sound insulation. Therefore, you also need to choose according to your needs in this field. In this case, consider the thickness of each part on one side and the distance between the parts on the other side. The reference considered in this case is the CEKAL coefficient AR (for amplified sound). They range from the AR1, which lowers the sound level from 25 dB to 28 dB, to the AR6, which is recommended for regular flights or trains.
Conclusion
In summary, double glazing comes in many variations. It is equally well suited for windows, doors, windows, or skylights. Choose the model that best meets your needs by comparing the different possible combinations on the double glazed window market. Finally, it is always advisable to request a quote several times before installing or renovating windows.
