The windows of the attic can be considered part of the surface of the roof. With modern construction technologies, in particular the installation of the roof, the window system of the attic in which double -glazed windows are used, it is realistic to make as strong and reliable as the roof itself. And reasonably compiled double -glazed windows prevent heat loss and leaks, thereby providing comfort and heat the attic for the whole year.
Generally speaking, when choosing windows there are only two significant criteria. The first – for installation in the room of which type of window with double -glazed windows are determined, t. e. What functions are assigned to them, the second – the financial potential of the buyer. The size of the window directly depends on the angle of the roof and the distance between the rafters.
But, on the other hand, it must be taken into account that the window for the attic is a very complex translucent structure. From the point of view of technology, this is a device equipped with modern expensive devices. This only the base product includes a double -glazed window, frame and ventilation device, other models can differ in the opening method, and design, and the availability of electrical control. All windows are certainly equipped with a ventilation valve.
As a rule, single -chamber, frost -resistant double -glazed windows are used as attic windows, but they can be with some specific features. For example, the installation of embossed glasses, anti -vandal. For the lower part of the attic, two -layer safe glasses are provided, which, breaking, simply turn into safe crumbs, which are difficult to get hurt.
Based on the considerations of leaving unnecessary troubles, many owners of cottages when choosing windows for the lower installation give priority to self -cleaning double -glazed windows with hydrophilic transparent coating. The effect of self -cleaning is based on photocalysis of nanoparticles of the titanium oxide, destroying dirt particles under the influence of sunlight and rain. Literally after a few days of solar exposure, the coating is made active both in cloudy weather and at night, preserving this quality for at least 20 years.
Gas -filled double -glazed windows are also recommended – with crypton, argon, xenon, with heat protection glass, which has a low heat emission, infrared radiation. Naturally, the use of laminated or tempered glass is always advisable, but saving on heat protection, and then the little one, it is reasonable only if the window is planned to be installed in the attic of the summer cottage.
With other options for the purpose of the building (cottage, house in the city), the acquisition of a window with improved heat -shielding properties is justified from the point of view of economic.
