After double and triple glazing, here comes the heated double glazing in France.
We know it, to avoid the cooling of his house, we avoid the large openings on the north side, we say goodbye to its simple glazing, we check the condition of its joinery to avoid thermal bridges as much as possible.
But even if the large openings facing due south with double or triple glazing are wonderful for bringing in the light and thereby lowering the electricity bill, in the middle of winter and in gray weather, if the light remains off, the interior temperature near the openings, it tends to decrease due to the cold slowly captured by our glazing.
It is therefore in this case that the idea of the heated window takes on its full meaning.
Brief history of the heated window
Heated windows were developed just over 20 years ago in North America, in very cold areas. Designed from the outset to thermally protect the large glass facades of shopping centers, ocean liners and other industrial buildings, heated windows are in fact the basis of heated glass panels. By that, you mean that at the time, this technology could only be applied to stationary glazing and not to domestic opening windows. It was not until recently that this technology was made available, in the form of casement or sash windows for collective and individual dwellings.
Functioning
The heated window works like a convector type radiator.
It intelligently combines two functions:
1. It warms the house with heat radiation
2. It also serves as thermal insulation in the envelope of the house.
The window consists of two tempered and sealed glass plates, between which a gas is injected. A weak electric current is propelled inside this double glazing which allows to heat the enclosed gas and the interior glazing at the same time.
A monitor is installed near the glazing to control the desired temperature.
Advantages of the system
Energy savings
The heated window, when it completes a high energy performance type BBC construction, can completely replace the usual backup heating and allows energy savings. According to the installers of the system, the energy required to heat the glazing is less than that required by any other auxiliary heating.
Hygiene
The heat induced on the double glazing prevents the formation of condensation responsible for the molds that are too often seen in the window jambs. Exit therefore the problems of allergies, of unhealthy humidity at the level of the window joinery causing detachment of paints, air and water leaks, the problems of thermal bridge etc.
Aesthetic
According to our research, the difference between conventional double glazing and heated double glazing is hardly noticeable. Especially since the heated windows can be delivered in wooden joinery (across the Atlantic). The power cables are completely concealed in the window frame and in the walls. Visually, the heating glass can be quite confused with a conventional low-e glass. Only the electrode installed between the two panes makes it possible to distinguish the two systems.
Safety
The glass sheets of the heated window are tempered, for perfect resistance to possible impacts and thermal shocks. The conductive layer is sealed inside the double glazing, which avoids short circuits in the event of water or foreign matter infiltration. This system protects users from any electric shock.
New in France
In North America and the Nordic countries, the system has already proven itself and has gained a lot of support. Particularly because the system is discreet, has a certain ecological interest and a wood version is available.
On October 12, we read on Batiweb.com that the company RP Technik (KDI group) will present at the Metal Expo 2010 show (Paris Porte de Versailles from November 16 to 19) the “Steel Climate Line with thermal barrier” range , range with the IQ Glass heated glazing system.
Heated windows should therefore soon be available in France for collective and individual dwellings in steel version, but when will the wood version?
