The variety of metal doors today is so great that the choice needs not become a simple occupation. Each seller praises exactly those doors that he has in stock. How to understand which door suits you in price and quality? What to pay attention to first of all? Choose the door competently so that doors do not require repair.
Any door consists of a door and box canvas. Doors canvas is a frame that is closed on one or two sides with metal sheets. In the doorway, cheaper instead of an internal metal plate, an organite or plastic is placed. Very cheap doors generally consist only of the frame and the front iron plate.
Important characteristics of the door are its strength (hacking resistance), noise insulation, thermal conductivity and fire resistance. Well, of course, the appearance is also not the last characteristic.
The strength of the door is determined, first of all, by the characteristics of the metal from which it is made, the quality of welding. Then it is worth paying attention to the possibility of changing the lock and the presence of anchor and cross -country mechanisms that allow you to block the door in a closed state.
Noise insulation, as well as the preservation of heat in the room in the functions of the cheapest iron doors is not included. After all, their door leaf consists of only one layer of iron. And iron is very well missed by sound and cold. More expensive models in the door leaf include special layers of foam, foamopylene, cotton or foam. The ability of the door to maintain heat and not to let sounds from the street depends on what materials and in what ratio are used.
The filling of the door leaf can increase or vice versa to reduce the level of fire resistance of the door. Composite layers, although they are more expensive, but allow you to make the door more reliable in terms of protection from fire, noise and cold.
The appearance, paradoxically, is at first glance, also affects the degree of safety that the front door is capable of ensuring. Do not make the door such that is very different from most of the surrounding doors. This can attract the attention of robbers.
You can decorate the door with a tree with a tree (it will look like wooden), uprooting by a leather -altitude, welding forged decorative elements on it.
