Sliding door - types and design features

Doors - this is the element with which we deal every day. By the method of opening, they can be divided into swinging, folding and sliding. The most common for us - swinging. These are the doors that are fixed on hinges on one side and open to themselves or from themselves (or both sides). Folding consists of several narrow strips, fastened together by special devices. When opened, they add up as an accordion. It is very convenient, if not for one "but" - they almost do not protect against noise, since they have too many joints and cracks. The sliding door is in the middle (in terms of protection against noise) between these two types. It is a door leaf that moves along special guides. In the open state the canvas can be placed in a special niche in the wall or placed outside along it.

The sliding door moves along a rail that may be on the floor (rail of a floor rolling), or at the top of the door frame (in some cases - on the ceiling). The use of top rolling is much more convenient, and is easier to implement. This system consists of a rail (rail), two carriages with rollers and a stop limiter. The carriages are often duralumin or are made of extra strong plastic. They have four or two pairs of rollers. To make the door move smoothly and noiseless, use bearings. The guide is most often made of aluminum in the form of a letter "P" with small A shelf that supports the rollers. The main advantage of top rolling is the almost complete noiseless operation. Previously, there was a problem: during the operation of such a sliding door, it was blurred, and therefore quite often deviated from the desired path of motion. Today, this problem is over, and the solution for different firms is different. So, the company from St. Petersburg "Alf" and Italian Astor Mobile use a wooden bar located above the carriage , which extinguishes possible fluctuations. Rimadesio has manufactured a special form of silent aluminum rails (one and two-lane), which prevent the door leaf from deflecting.

When using the lower rolling element, the sliding door moves due to the rollers that are located at the bottom of the frame. The design assumes the presence of an upper rail, but in this case it is used only to increase its stability. This system does not allow the canvas to swing - fastening is quite tough. But usually prefer the upper method of attaching the blade. This is due primarily to the fact that the rail on the floor is a rather inconvenient device. About him you can stumble, he quickly hammered, and cleaning it - not the most fun. In addition, the rail must be mounted in the floor covering, which destroys the integrity of the latter. This system of door opening is most often used in closets. In this case, you are Do not have to stumble on the rail. Sliding sliding door with a lower rolling method is the best option for built-in furniture. It is most often found in our apartments.

Sliding door-pencil in the open position hides in a special box, installed in the wall. It is desirable to install this structure either during major overhaul, or during construction. If you decide to put a door of this type in an already renovated apartment, you have to take apart part of the wall, install the box, and then seal it. However, this sliding door has the advantage of high noise and air insulation: special seals are used in the design. Also this system works almost silently, has a lock, is often equipped with locks or other locking device. So a sliding door of this type is a good choice.
