If the door is made from wood substitute (MDF, particle board), then prior to processing the finished form it is filled with a special material. This material retains moisture and is used for noise insulation. The latest invention of Canadian experts - the so-called needle stitching. The door is going out of bars and joints that connect the joints. It was he who, as experts say, perfectly prevents the door from temperature fluctuations. Today the price of such doors range from $ 400 and above. By the way, the buyer can always distinguish the fake from the "native" products just to acicular seam. "Zigzag" should be slightly visible through the paint on the end of the door frame. The price of the combined door depends on what material it is filled with its "filling". 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 (see Fig. 1). 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 (see Fig. 2). Often domestic producers in order to save molded veneer directly on the boards, without the interlayer. So do not be surprised if your door in the bathroom, where natural humidity is high, will get unstuck. Figure 2. Sometimes Honeycomb not put. These doors are called hollow.

Experts advise: If your bathroom is "Jacuzzi or sauna, it is better to buy a plumbing the door of the combined material and not from the array. Solid oak door of course, but the wood even after treatment preserves the properties of natural fibers. They "breathe" and absorb moisture, so the door may warp. Also note - the more the panels embedded in the door leaf, the less likely it is deformed due to moisture. As it turned out, the foreigners have long learned to take care of their plumbing doors. For example, Americans know a great time-tested way to deal with moisture. It is known that after a hot shower on all surfaces, bathroom sinks pairs. They puncture the sanitary door opening. Typically, a hole cut down through the bottom of the door frame. Moreover, this procedure should prodelyvat after the buyer has set the door of the apartment. Do not worry, you will not see the hole. Save a decent view you can use a regular lattice matched in color and reinforced with inner and outer sides of the bathroom door. Our builders have somehow never such vents and the lattice plumbing doors do not. material.ru
