To solve this issue, it is necessary to clearly understand what functions the front door should perform. After all, it is clear that universal, "ideal" doors do not exist. Therefore, in order to choose the suitable entrance metal door, it is necessary to understand what exactly it is needed for: an apartment, an individual structure, a summer residence, etc.
Functions of metal doors
Protection against penetration from the outside
Penetration can be carried out in various ways.
First, with the help of mechanical action( sledgehammer, scrap) or brute physical force. Therefore, the design of the door must meet the requirements of reliability and strength.
Secondly, penetration into the room can be accomplished in an "intelligent" way. Various picks, devices for unlocking and opening electronic locks, etc. Hence, the design of the door should ensure the installation of locks of varying complexity and configuration.
Third, there are situations that are classified as a "special case".For such non-standard situations, doors are produced that are resistant to surface breakdown( bullet-proof), fire( fire-fighting), etc.
Fourth, there is a need to provide access to the premises only a limited number of persons. Accordingly, the ban on the entry of strangers. Such doors are equipped with access control systems( access control and monitoring system).
Insulation of the room
It is clear that drafts in the apartment few people please. Yes, and various sounds, noise on the landing is also not needed by anyone. Therefore, a good, high-quality door should provide reliable heat and sound insulation.
Appearance
Everyone understands that the first impression of the owners of the dwelling begins to take shape already from the entrance to the house. Therefore, the appearance of the entrance door is of no small importance. If it looks bad, looks grim, then the impression will not be the best.
Currently, metal doors, which are sold in various salons, are produced by both foreign and domestic manufacturers. By the way, Russian doors are not only of good design, but also of high quality. Many Chinese-made models are also on the market. They are inexpensive, but there is no quality to comment on.
If you already have certain preferences for choosing a door, its main characteristics, you need to carefully inspect a particular model before buying it. Do not focus on the content of beautiful advertising booklets and extensive explanations of the seller of the salon. He only needs to ask clarifying questions, and to check himself, with knowledge of the matter. The seller let him buy himself what he likes, and we buy for ourselves.
What to look for when choosing
Dimensions of the doorway
Before you go to the interior of the furniture, you need at home to make all the necessary measurements( height and width of the doorway).All doors come in several basic sizes. It is necessary to choose such dimensions of the door, so that you do not have to either expand the walls too much, or vice versa, to cover up the remaining space. Do not take the door already, than the one that stands. It is necessary to take into account the fact that some things, new furniture or household units will have to be added to the apartment. Will they "go" to the narrower door?
Filling the door
This is what insulates the door, and provides sound insulation. If the door is flooded with lead or concrete, then it is suitable for a bank, not for an apartment.
Filling the door frame
This, of course, increases the price, but what is the practical meaning? Nobody in the entrance of the house will not use to break the door with a welding machine or a Bulgarian. Even the most "near-minded" robber understands that neighbors have ears.
Is there a second sheet of metal?
The strength of the door is determined by the quality of its stiffeners, by their mounting, and not by the number of sheets of iron. If there is a second sheet, it means that the design is not the same. If, of course, this is not a special order, not an exclusive one. But the price is already appropriate, because the metal is expensive. But why do we need this? Pay for what?
Hinges
The most reliable ones that keep on the support bearing. How does the door open? It should open outward, not inside. If inside, then using a good jack, it just "squeezed" into the apartment. And without the accompanying sound effects, in a quiet way.
Door perimeter and lock
Is there a seal on the door? Otherwise, when closing the door there will be a constant clank. And the dust will penetrate into the room.
What lock is installed? It is better to take the door with the lock of the "crab" system. Even if the hinges are cut, metal locks( pins) from above and below will not allow it to be removed.
Number of locks. Practice shows that the required minimum is two locks. The best locks are protected by imported locks.
What guarantees does the "seller" have?
I have to ask if there is a warranty department in the manufacturing company. It's safer. And yet - how long does this firm exist? And then not for long to come across and "one-day", which then it will be impossible to find.
