Most often, plastic doors are used as an entrance for a private house. In addition, they are installed at the entrance to the boiler room and garage, farm buildings and a swimming pool, a closed terrace or a winter garden.
For the manufacture of a plastic entrance door, horizontal and vertical profiles are used that have five air chambers and stiffeners. Profiles, in turn, are made either from plastic, or with the addition of reinforcement from metal. All parts of the frame for greater strength are connected together by means of metal bonds. Such a frame of a plastic door can be of a variety of shapes: rectangular, trapezoidal, arched, rounded, etc.
On the entrance plastic door are installed special bolts and power loops, closers and strong, reliable locks. A multi-locking mechanism ensures a tight fit of the door along its entire perimeter.
Filling the plastic door
Filling the entrance door is of two types: dull and translucent. Deaf filling is done using sandwich panels. Such panels are made by three-layered: between two steel sheets the heater in the form of expanded polystyrene is laid. All three parts are glued together with polyurethane adhesive.
The translucent filling of the entrance plastic door is often combined: the upper part - with a double-glazed window, and the lower part of the door becomes deaf. However, the options "plastic" + "plastic", or "glass" + "glass" are also found.
Glass for the entrance door can be used and matte, and corrugated, and colored and even stained glass. Deaf parts of the plastic door can be laminated with a color film or under a tree.
The entrance plastic doors can be either single-leaf or double-leaf. In this case, they can have a transom, or be without it. Two-leaf doors can also be stump: one half of the door is fixed to special latches, with which the door opens only as needed. In addition, there are entrance doors made of metal-plastic and sliding.
The color of metal-plastic doors can be chosen any: gray, white, mahogany, dark oak, golden oak. The main thing is that the color of the plastic front door looks good against the background of the rest of the room design.
On the plastic doors are installed locks of two types: under the pressure handle and under the handle-arc. However, more reliable for the front door is a lock-barrel under the handle-arc. Together with it, the door closer is installed.
