There is practically no housing in which the installation of interior doors would not be required-even the studio apartments must have at least one door, besides the input, of course-the door to the bathroom. During the repair, stained wooden doors standing in the apartment from time immemorial are increasingly replaced by modern doors trimmed with veneer, laminated or doors from the wood array. Most doors manufacturers, especially large factories, are guided in the manufacture of door leafs, boxes and platbands with standard sizes of doorways. When recounting on the size of “along the canvas” (in fact, the size “according to the canvas” is the real size of the opening after installing the door) Russian standards are an opening with a height of 2000 mm and width, depending on the purpose of the door, 600, 700, 800 or 900 mm. New houses under construction have often have the doorways of the European standard, this is due to the fact that many construction companies use projects of modern houses developed by foreign architects and already tested abroad. The European standard from the Russian differs only in height – the doorway has a height of not 2000 mm, but 2100. For a standard doorway, you can buy a door in the store. And what to do to the inhabitants of the old ones built before the introduction is not like the standards on the door, but before the introduction of the concept of GOST, houses, which are especially a lot in St. Petersburg ‘in the apartments of the old housing stock, as a rule, are installed by the doors manufactured by individual projects, custom -made doors. The installation of non-standard doors is also often different from the installation of doors in the usual 2000×600 … 900 mm, since the old doorways can be not just a non-standard size, but not quite a rectangular shape-somewhere part of the wall broke, somewhere the wall was just led (especially This is suffered by openings in the unnecessary walls-breeds, which are a “layer pie” of two rows of boards with insulation between them, fights, plaster and wallpaper (sometimes newspapers of the beginning of the 20th century can be found under the wallpaper)). In such cases, a wooden aperture beam is installed under the box, and if the opening in height turns out to be too large (there are openings up to three meters high, and sometimes more), then the installation of the transigestion is necessary (it can be made and glazed – depends on the wishes of the customer). The appearance of the door is also important – a laminated or simply painted wooden door will look pale in the old pre -revolutionary building house compared to the array door or an extended door. As a rule, such doors are made with a large number of a variety of philanes, sometimes with glazing. Only a relatively small door manufacturing workshop that does not need to rebuild the established production process will be able to quickly cope with the task of manufacturing a non -standard door of high quality, as well as a high -quality installation.
