For any housing, doors are very important. Once, a primitive man put at the exit from his home a primitive fence to protect against wild animals. Then he noticed that the denser the fence, the warmer indoors. Thus, the main purpose of the doors was determined – the maintenance of heat in the house. During the period of global cooling on Earth, insulated doors in dwellings, have preserved many lives.
Gradually, the doors are being improved. In addition to strong entrance doors that protect the house from uninvited guests, internal doors appear, separating rooms. People, trying to decorate and diversify their home in any way, perform a variety of threads on the doors. The main material from which the doors were made, until the end of the 20th century there was a tree.
And more recently, the industry of building materials proposed, practically, completely new doors. Strong metal entrance doors reliably guard modern dwellings. Internal doors are made of light polyhlorvinil (PVC). And the entrance to public buildings is decorated with beautiful and durable metal -plastic doors. The doors of public buildings throughout the day very often open, missing numerous visitors.
And, unfortunately, not everyone considered it necessary to close the front door. Therefore, in the cold season, precious heat went through open doors. Many still remember metal springs that helped close the doors. The developers of new door systems and locks offered an automatic closer to close the doors. Such high-quality closers and locks can be conveniently purchased for example, in the Plast Market online store. In addition, this store also offer other accessories for doors and windows.
Modern closers for closing doors help silently and tightly close the doors behind each visitor. And this allows us to significantly save the costs of heating the premises, because many modern offices are input directly from the street, that is, there is no vestibule or corridor. And, of course, the aesthetic appearance of such closers is much more pleasant than metal springs.
