All of the doors

Architects, at all times, have paid special attention to the door, all the architectural styles are not spared their attention and doors, whether Gothic or Art Nouveau. The artistic decision of doors can be traced back the history of architecture and this topic can devote a whole separate issue. Development of new materials and technologies in construction, also avoided the side and doors. Opening doors to the world of conventional design of doors was developed in ancient times. During excavations at Pompeii were found doors are very similar to today, they already had locks and hung them on hinges. In the XVII century in France, came into vogue glazed door (they had a prototype box extend to the floor). These doors are now widely used in public buildings, but only with the use of new materials and technologies: special glass doors not only provide the desired decorative effect, but also to reliably block access to the building uninvited guests, and special solar cells opens the door automatically, or, conversely, necessary, block them. In Denmark, were invented by the door in two halves (for better conservation of heat in the house). Without opening the entire door, through the bottom half, it was possible to produce on the street cats and dogs. In the past century the door with a hydraulic, pneumatic and electric drive. At the same time born folding, sliding and revolving doors. Since then, the ancient tree is a traditional material for the manufacture of door and window frames. Due to its isolation from cold and noise properties, with the flexibility to use and simple operation, a wide variety of colors and textures of various types of wood, the tree was and remains the most used material in the manufacture of interior doors. Thanks to technology and processing (drying, impregnation, tinting, paint, etc.), used industrial woodworking companies, interior doors made of wood provide users with additional assurance of quality, durability and stability of the product. On the authority of the German Institute for production technology of bindings, which institution shall examine the behavior of various materials, wood binding is very good on the following criteria: variety of colors, ability to handle both in size and shape (the variety of typologies), resistance to wear and weather factors water resistance (permeability of joints, and resistance to direct penetration of moisture), heat and sound insulation, resistance to condensation, cleaning, repair. A tree has one more feature that distinguishes it from other materials: it is lively and reflects the unrivaled symbol of not only the wood, but also a single plant, from which it takes place. The tree itself, it is individually, uniquely and simultaneously similar to other trees of the same forest to develop textures, along the lines of the fibers by the presence of small sound knots, making the tree immediately recognizable as a true expression of life in the plant. In this connection, a door or sash, made from the same timber may differ from one another by color, for example, leaving, however, the same typical characteristics. If the manufacture of doors and windows from wood using the results of research and technological development, it allows to achieve and maintain performance and product warranty from the tree are the same or even higher than that of any other material. The role of the doors open and close the door, pretend and cover up, up and down and, finally, the door slammed. The door and put up at the door meet. You can be rude to ask to close the door on the opposite side, or say that they will wait for you all night with her. A closed door may seem mystical, unifying, forbidden, intimate, arrogant, discouraging, patronizing. If a door slams, then someone is angry, and sometimes, though, it can cause drafts. Under the door eavesdropping; hiding behind the door, tears or smiles; linger at the door, saying goodbye. The door is the border between your inner self and the outside world. There are lots of reasons that determine the purchase of new doors for residential and nonresidential facilities: some require a lot of space and he wants to create a more rational division of the space at home, someone is more sensitive to the problem of style and looking especially refined design, with particular attention to detail and finish, there is someone who wants to turn away in his quiet corner to leave the door everyday concerns, problems and failures of their own, someone just wants to replace the old, lost priglyadny appearance and squeaky door, and there is someone Finally, someone wants to bring fresh impetus to innovation and to give house furnish personal notes. The choice of doors is huge, and it is due to many tastes of buyers. But, regardless of lifestyle, the main requirement for the door has been and remains a guaranteed quality and consistency of characteristics over time. Classification doors doors, depending on their position in the building, the number of blades, the method of opening, etc. can be divided into the following, the main types: the location of the building, opening the way to the material, the number of canvases, filling the door leaf, the functional purpose. According to the location in the building doors are exterior, entrance and balcony, interior and cabinet. By the outer doors of higher demands of sound and thermal insulation, security (protection from unwanted intruders), and if the door leads into the street, it should withstand rainfall. Reinforced entrance door may be different, which primarily depends on the materials of manufacture: wood, profile (aluminum, PVC), steel, combined. To provide heat and sound insulating qualities applies several technologies: More interior doors, door manufacturer of a bulk material is placed inside a cloth and special sound-insulating materials. All wood exterior doors, regardless of internal structure which must be addressed to the street outside the panel, made of wood, specially treated and coated with a protective varnish or paint. What would be better quality coating, the longer it will last the door. Steel doors - it's front doors, which, above all, inadequate protection of the home. Depending on the design could be fire, burglar, bulletproof, resistant to blast. When you select a door and hardware for it to consider such an aspect as an opportunity to save in exceptional circumstances, that is, the door must be versatile, which should be taken into account in the planning stages and requirements definition to it. Discussing Furnishings apartment or cottage, the owners sometimes forget about the role of interior doors in shaping interiors. What function they perform: the continuation of the wall or a piece of furniture? The answer to this question is not so simple as it might seem at first glance. Affiliation inner door wall or partition is undeniable. The design and dimensions of the product, method of fixation of the box depends on the material of the wall, the destination is fenced off areas, the geometry of the door opening, etc. However, interior doors - an essential attribute of the interior. Their choice is caused primarily designed interior of the rooms. For example, the wooden door is mainly produced for the interiors in a classic style or modern style. For the first use products with paneled relief. Mod doors usually have a smooth surface. Color is adjusted depending on the world of color furniture and the floor. Wooden doors are usually a tone lighter or darker parquet flooring, if not contrasted with it. For cutting-edge areas (hi-tec and others) are made with aluminum doors and plastic inserts. Doors made of timber and processed wood products (particleboard, MDF), may have fancy designs and are used in neutral or eclectic interiors. The special charm of interior doors gives the glazing. For this purpose, decorative safety glass or stained glass. Purchase of products from glass should be carefully considered. Door with a colorful stained-glass window can introduce an imbalance in the decoration of the room. Note that the plastic doors are commonly used to exit to the balcony, a loggia, terrace, winter garden, etc. In the living rooms of them, as a rule, do not install. On the market interior doors of various designs. Classics of the genre is considered to be the usual single and double product. Door leaf and form a box door unit. As a decorative border using frames. The kit includes hinged door rubber seal (fit in a box for low noise) and FLEXINVEST (extender boxes, etc.). Continuing interest of consumers cause sliding doors. In addition to saving space usage of such products can be realized in the interior of unusual design solutions. Large sliding doors degenerated into a wall. Linens move on rails, which can be attached to the ceiling, the wall (in overhead ") or beamed way (at the disposal"). Usually set up to four panels, whose motion can be single-track (at the door with one or two paintings) or dvuputnymi (with two, three and four canvases). Methods and differences Doors also differ in the way of opening. They are hinged, sliding, folding and rotating. The most well known and familiar - the door swing. They can be opened in one direction or both, ie be swinging. Applied and both internal and external both. Can be glazed and deaf. Such doors can be made from any material used for the manufacture of doors, and have any design. Swinging doors can be, as a threshold, and without it. In modern designs, the threshold is automatically lowered, which improves sound and thermal protective performance doors. As you know, odnopolnye doors are left and right. If when you open the door "to a" loop are right, it is the right door, if the left - the left. Modern Deaf doors - universal. Swing doors - the most common door, and not without reason. They are easy to manufacture and easy to use, have a long life, make efficient use of the entire doorway in the wall. Solidly made and properly installed, this door is virtually maintenance free, except occasionally - in the grease hinges. Its doors can be made of different materials, wood, metal, glass, plastic, and combinations thereof. The main characteristic of swing doors can assume the existence of zones openings. In swing doors, there is one drawback, they require a certain amount of space to open, and it's not always convenient, especially in close quarters. Therefore, the light appeared, sliding doors and folding. These types of doors provide an opportunity to create the necessary interior increases transformability premises, as well as with their help, it is easy to redevelop the inner space, both residential homes and public buildings (offices, restaurants, conference halls, etc.). Sliding doors, when you open or go into the cavity inside the wall, or move parallel to it. They are applied and both internal and as an input to public buildings, often with the use of modern automation. For door trim using modern materials: glass, laminated, mirrors, wood veneer, as well as combinations thereof. Currently, this type of door is also widely used for so-called "wardrobes". Folding doors give the interior of originality. They feature a sliding mechanism. A leaf sample are for fixing parts of the valves to each other. Design leaflets similar structures fold hinged doors, with the exception of folding doors from the array. Finish folding doors is as diverse as swing. This veneer, and melamine paper, and laminatin etc. Folding doors are solid or glazed. For decoration apply paste of various types of glass. Folding doors composed of separate sections that move along the rail installed in the doorway. They may be deaf and glazed, made of solid wood, plastic, coated with natural wood and other materials. Apply, such as interior doors only. Turret (revolving) door used in public buildings (hotels, department stores, airports, etc.). They come in two, three and four valvular performance, with manual or automatic opening. On the material used to produce doors, which can be divided into: Wooden, profile, based on the profile of PVC, based on the profile of aluminum, steel and glass. Modern door - it's modern materials. Tree - Dried and processed by the new technologies, new tree-like materials and their combination in the construction of doors. The wooden doors are used as external and internal as for residential and public buildings. But if, as internal, interior (living room), they surely continue to hold first place for use, when used as exterior, currently, they have acquired serious competitors. They are the steel door and the so-called profiled doors, based on designs that use aluminum or PVC profile. Sectional doors are perfectly combined with modern facades and specialized input groups. A steel door can provide the required safety facilities. Sectional doors, at present, have been increasingly used as an internal business centers, malls, banks and other public buildings, often in conjunction with relevant partitions. Both domestic use and the steel doors of hladognutoy sheet steel. They can fully simulate the wooden door, having the same division canvases, panels, and embossed wood texture. Glass doors extend the range of opportunities for the architect's organization of the entrance to public buildings and interior space. Doors can be combined, made using different materials, which increases the possibility of giving them the necessary technical specifications and external forms. Depending on the number of canvases, the doors can be: odnopolnye, dvupolnye, sesquioxides (with two blades of unequal width). Doors three-and chetyrehpolnye used very rarely. The number of paintings door dictates, as a rule, the width of the opening in the septum or wall. Aperture width depends on the functional purpose of the premises and fire safety requirements. All double doors, but swinging require additional locking elements - door latches. Latches are typically installed on one of the two wings double-door or on a narrow sash polutorapolnoy door. Sash, fixed top and bottom latches, becomes like a part of the door frame, while it is always possible to release and open, expanding, thus the doorway. To fill the leaf doors can be glazed and deaf. Balcony doors are always making glazed, energy-efficient. Internal doors are also often make glazed, for example, to illuminate the second light auxiliary facilities. With the same purpose, transoms over the doors suit. Glass or glazing can be transparent, opaque or embossed with a pattern of different colors, with stained glass. The form of glazing can be very different, as the traditional: rectangular, arched and circular or even triangular. For rasteklovki doors are used gorbylki (false and real). A difficult choice before opt for one or another door, tediously clear about this: What are the demands we make of interior doors? From what material should be our interroom door? Which door design we want to see in your house? How many will stand our purse? What doors do we need for the option to open (right or left)? What are the dimensions of interior doors do we need? What kind of interior doors come in at all? The doors of inlaid solid, veneered or MDF, glass or metal elements, with one or two panels, smooth, dull, or behind glass doors to single-or double, symmetrical or asymmetrical, with a porch (chetverchenye) or without it. What material is the most practical for interior doors? In the first place, the doors are classified according to material of manufacture, they can be conditionally divided into deciduous, coniferous, combined and doors made of artificial materials. Since time immemorial, the most common material for the manufacture of doors are wood, deciduous and coniferous. Russian masters have traditionally preferred the oak. For the door trim was used and more valuable species. Today, along with the wood used and other materials. This wood derivatives (plywood, chips), polymers, glass, fiber glass and metal. The doors of the hardwood most prestigious and expensive, here are the doors of solid oak, beech, maple and mahogany. Hardwood is different from other breeds, not only for its natural uniqueness and beauty, but also greater strength. These doors will serve for many years, durability and flawless operation of the doors of the array subject to compliance with the manufacturers of all cycles of the process in their manufacture, as well as the quality they apply adhesives and coatings. Doors of conifers - pine doors - these doors are cheaper. In addition, the pine is the most common material today. Due to its popularity because it is cheaper than the door of oak. However, many experts will tell you that these doors are only good for cottages, but not in urban apartments. And especially not in the bathroom and toilet, because pine rather "soft" wood material: that is why it is more exposed to changing humidity, can crack and shrivel. If you decide to choose a door is not solid, solid wood, but, for example, veneer, no harm will "see" inside her. The most advanced filling - dial-array - under pressure from bars joined by a well-dried wood, so that the direction of fibers in each layer was different. But they are cheaper and less prone to reactions to changes in humidity in the room. Expensive door is as follows: first glue sticks, pine, and then at them from both sides of the bonded layer of MDF. In the doorway cheaper "filling" is different: the pine bar is mounted only on the perimeter, and all the rest space is filled with jumpers in the form of honeycomb. Sometimes Honeycomb not put. These doors are called hollow. How much will it cost?

The most advanced filling - dial-array - under pressure from bars joined by a well-dried wood, so that the direction of fibers in each layer was different. "Mosaic" bars completely unpredictable (it is a cunning producer), but that such filler will help avoid the strain - a fact. Doors of composite materials. They are made of several components: the bars of solid oak, ash, maple, beech, pine and MDF. Wood veneer pasted over them. These doors are hardly inferior in beauty, durability and performance of the door from the array. But they are cheaper and less prone to reactions to changes in humidity in the room. The price of the combined door depends on what exactly the material it is filled from within. Expensive door is as follows: first glue sticks, pine, and then at them from both sides of the bonded layer of MDF. Then glued veneer of precious woods. In the doorway cheaper "filling" is different: the pine bar is mounted only on the perimeter, and all the rest space is filled with jumpers in the form of honeycomb. Then, as in the first case, a layer of MDF glued veneer of precious woods. Sometimes Honeycomb not put. These doors are called hollow. Price in the doorway of appropriate quality. The cheapest group of doors - the doors of synthetic materials - are the doors of MDF, particle board, can be covered with laminate. Here, as the saying goes, think for yourself, decide for yourself whether or not to have. The choice depends on many doors: exterior, performance, service life, or the optimal ratio of all parameters. We describe some things that will help you find the door to suit your requirements. Most interior doors are made from solid pine. Pine is quite hygroscopic rock. This means that when changing external factors such as temperature and humidity elements of the door block can change its geometrical dimensions (this is also a greater or lesser degree to the oak, cherry, mahogany and other materials). Also, the canvas door quite heavy, which increases the risk of sagging. To get rid of these deficiencies in the manufacture of doors must be respected by a number of requirements. Firstly, the wood must be dried. To make it qualitatively (remove internal stress fibers, moisture - 8.5%, etc.) need time and expensive equipment, which reflects the cost of the material. Second, all components of the door unit should have an ideal geometry, bars carefully glued, the surface is painted, varnished or high-quality materials to prevent moisture penetration into the wood. As for the doors is not massive (manufactured using modern wood-like materials such as MDF, particleboard, fiberboard, corrugated cardboard, etc.), then such interior doors initially not affected by the problems of warping and deformation and more stable. This is primarily a consequence of the production technology and properties of the materials used. MDF is less sensitive to moisture in the MDF for the same purpose add wax (factory Puertas Proma). Combination of the above materials in the manufacture of door unit (weight - corrugated board, an array - MDF - MDF, etc.) can achieve greater stability and easier construction. Materials themselves are less expensive than natural wood. Plus the opportunity to make the door on a fully automated production lines in larger volumes, without sacrificing quality. All this makes the interior doors made of artificial materials less expensive. Exceptions are interior doors, manufactured using modern technology, design know-how, inlay, or are produced in individual amounts for each customer. And finally, most importantly - security. Whether you buy the door from an array or not, I want to be sure that you have selected interior doors really that quality, which declares the seller. And here the more you say the name of the manufacturer. Doors - durable goods, and its quality is really tested by time. And if you get a door factory, which for 90 years and 9 on the Russian market - the risk to buy low-quality door is almost minimal. In the end, we note that if you do buy a quality door, then get high performance level, prestige, and beauty that will last for years. What else affects the price of the doors? Door price is determined not only the value of material or a timber, but also design. If the door is decorated with carved panels (panel - a thin board or plywood, inserted into the door frame), or by glass mirror inserts, expensive accessories (handles, locks, lock), then the price of the combined door walnut veneer can be equal to the value of the array. If the lock and door handle are relatively simple, relying on the taste and functionality of these accessories, then the choice of the loop need to know exactly which of them will come to your door. Thus, the hinges are universal and detachable. Adjustable height and porch 3D loop to fit any door and cause the least problems. Today, these loops are used in good doors more often.
