Entrance doors must meet strict criteria of reliability and durability, must ensure a high level of security and also prevent unauthorized entry, protecting against gross and intellectual breaking.
These structures require good thermal insulation properties, ergonomics, convenience and the ability to protect against street noise. In addition, doors should be visually attractive, as they are a visiting card of every house. As a design element, they should fit well into the surrounding interior and be in harmony with the overall style of the building.
Decorative exterior finish has an aesthetic function and serves as additional protection. First of all, pay attention to the installation location of the door structure. Increased requirements are imposed on the enclosing street systems, because they are in contact with precipitation (snow, rain), are exposed to high and low temperatures, and are also illuminated by ultraviolet rays. Outdoor street facing should provide reliability and good protection against these factors. Front door to the apartment is not exposed to such effects. For a high-quality door made of solid wood, for example, Victorian front door, no additional facing is required, except for coating with paints and varnishes that protect against external atmospheric factors. Metal sheets on Edwardian front door are lined with decorative panels made of wood, plastic, etc. Door structure can be treated with powder paints, which are applied by extrusion technology.
Completely wooden doors are rarely used, since they do not provide the required level of security and reliability. They find application in elite suburban mansions, various institutions and where there is support for additional security systems.
