  1. If the consultant enthusiastically tells you about the door, the interior of which is filled with lead shavings combined with buckwheat husk and swan's down, then he did not hesitate to clarify why there is all this necessary.Modern reliable door must be protected from the street or driveway cold, not be too heavy, and it is desirable that it was made of high quality metal.As an internal filler ideal insulation Isover, and everything else is already redundant.
  2. door frame - another element of the front door.There are two types of door frame - closed or open.The closed design is welded to each other formed sections.This box is very robust and reliable.No closure of the design of the door frame consists of a curved profile, which significantly reduces the cost of the entire set.This box does not have sufficient rigidity, however it is filled during the installation of concrete mix (for more stability and strength).Some sellers, using the fact that the buyer is in this matter a little aware, wishful thinking - are beginning to convince you that this measure is an advantage of this door, forgetting to mention that without the strengthening of concrete box door will not work at all.

What doors better - cheap or expensive ↑

To learn what doors better, you need to figure out the maximum information about those and others.

  1. Cheap doors worth up to $ 150.

relatively low price may be a conventional publicity stunt to get on that can you.For the money you will be offered the most primitive door consisting of two aluminum and even steel can, sheets, plates fastened together, or so-called ribs.This package will be supplemented by two locks «made in Russia», «elegant" giant-sized keys, a normal door handle and eye.Oh, and the weight of such a door about 100 kg.

If you have a desire to strengthen and seal the door, you'll have to pay extra.Each additional element not included in the basic package will be installed on the door of your click - only manage to open the wallet.

For example, a layer of batting average is about 100-150 rubles, mineral wool - 200-230 rubles, Foam - 300, and from makrofleksa - approximately 400-450 rubles.So consider!

Next costly part - a castle.If you are not satisfied with the standard version, which comes (and it is likely you are not satisfied), you can prepare your wallet again.Castle with a more complex configuration, with clasps and pins will cost you a decent amount, and yet it is still necessary to establish, as soon as you put in popularity.

Come on.You have decided to expand the doorway, then you have to pay again.This procedure will cost you about 30-40% of the original cost of the door.To what extend the opening?Everything is simple and trite.Often the size of furniture or household appliances exceed the size of the doorway and make such purchases in the apartment or house is extremely difficult.Much easier if a standard door width of 80 cm will have very different parameters, such as 90 or even 100 cm.

If you add up all the expenses, we get an entirely different figure than was stated in the beginning.Instead of $ 150 steel will cost you 200 in all, and even more.

Castle doors have imported super reliable, because each key is produced in a single copy, but the lock has more than 3 million key combinations.Make a duplicate is impossible without a special computer card that is attached to the set.You can order a special kit consisting of three keys, different from each other, but correspond to one lock.For example, you have lost one of the keys, and order a new one in no time.Then you just take a second key and open the door for them.Now lost keys do not open your door, even if it exists.

What makes metal doors ↑

To understand what should be the front door.we must deal with the fact of what and how it is made, because you are interested in any of the meat made sausage, lying on a shelf in a store.Same with doors.

Robust steel
Elite entrance metal doors with insulation, construction

All doors quietly and peacefully standing on the trading floor can be divided into two categories - the doors, made in a small firm, which occupies the basement in the short nine-and doors,producing a large company, so to speak, "shark door business."

small company mainly works on individual orders, because she has no reason to make tens or hundreds of doors in a month - where to get as many clients?Yes, and buy expensive equipment is no hurry - why?It is because of poor technical equipment of the door, made such an enterprise is hardly the acme of perfection.

Welding is done by hand, because the joints are obtained and is not always smooth and perfect, but it can only mean one thing - in 3-4 years can deform the door, locks jam, broken thermal and acoustic insulation, and in general your apartment becomes unsafe.

Large corporations also clear traces not only their image and reputation, but also the quality of products they produce, in fact this option could not be better characterize the reliability and honesty of the seller.The most important difference of a large firm from a small producer - level process and equipment, for the reliability and durability of the metal door is directly dependent on the quality of steel, dimensional accuracy of steel sheets and advanced assembly technology.

On larger plants are trying to prevent deformation of the metal sheets used for these purposes special listosgibochnye machines, by which to produce almost any profile.Agree, a solid piece of metal is much stronger than what was welded from pieces.

Finished sheets are strengthening ribs by spot welding, to achieve a perfect geometric shape of the box and the door.This door will serve you for decades.

not save here and insulation - the interior of the door is filled with different materials - mineral wool, expanded polystyrene, foam rubber, etc.Manually inserted eyes, locks, latches, installed decorative panel.Incidentally, the latter is established, and does not stick, as is often done craftsmen.

This door turns reliable, durable, strong, just be what you need.

Castle - choose wisely ↑

In order, how to choose the front door, we were defined, and how to be a lock, because this design element is no less important than the thickness and quality of metal from which made the door leaf.

Steel entrance door with lever locks
lever lock - the most common protection system, is equipped with a metal door

usually metal doors are equipped with two types of locks - cylinder and lever.

  • lever locks

lever locks are very reliable and sturdy, they are massive enough and perform a power function.Thanks to these characteristics it is difficult to knock out the castle and it is difficult to open.basic element lever locks - a code plate or levers.The minimum number of plates inside the housing must be at least 6. The more, the more reliable the castle.

Important: if you want to know the level of secrecy lever locks, then count the number of steps barbs key, because the number of steps corresponds to the number of levers.

  • cylinder lock

cylinder lock is also called auxiliary, probably because it is slightly smaller.Most often, the second type of lock is used when you need somewhere to go for a short time (to run to a neighbor for salt or to the store for bread).Break the cylinder lock is not difficult, but to pick up for him a suitable key or master key to open it is very difficult.

Cylinder locks have an internal mechanism, its appearance resembling a cylinder or circle.The key for this lock is flat and at its edges and in the middle point has recesses and notches equal to the number of pins in the cylinder.Accordingly, the more cuts on the key, the more secure the lock.If there are more than five, then this is almost impossible to open the lock, and to forge key also does not work, because they are made by a special technology based on the use of punch cards, or laser.

This technology will not allow thieves to make a duplicate at the first corner, because to get it right, or they will need to go to the factory, where they will be sent immediately to hell, or representative office.But even there, they do not shine, as they will need to present a special card, on which the encrypted code.If you bought a cylinder lock, and complete the card is not found, it means that you have made in laser technology.Having lost the key, you have to completely change the cylinder, so be prepared for additional costs.

in combination with each other, both the lock can reliably protect your home from unwanted visitors, so always when leaving the house, close the door on both locks.

Rigel - needed or not ↑

question, of course, almost rhetorically, because no one will refuse additional protection.Rigel - this is such protection.

general bolt or if you would be so easy, metal pin, it provides a secure fit doors inside the box.There may be three, maybe more, it all depends on the size of your wallet.

Settle bolt directly inside the leaf, and if you open the door, they will not be seen.But by turning the key in the lock (or a special pen, located adjacent to the keyhole), bolts come into action and go out of their nests, closing the door firmly.Usually such pins are located on the lock side, top and bottom of the door leaf.

addition crossbars steel anchor may have anti-burglary system, consisting of metal pins, which are from the end.At the time of closing the door they enter the holes located in the box, and securely locks the door.Now it is precisely nobody will be able to take off or open loops.

Additional lotions ↑

order to attract the customer's attention to their products, and even, to some extent, to surprise him, many manufacturers use a syllogism.They are mounted on the doors a variety of mechanisms to protect them from tampering.

Given the presence (or absence) of such levels of protection, all metal doors can be divided into 4 classes:

Class 1. The door can not be opened by using simple tools and the use of physical force.

Class 2. The door can not be opened using any tools except electrical.

Class 3. The door can not be opened by any instruments, including electric power and no more than 500 watts.

Class 4. All of the above advantages, combined with ballistic.

But before you assign your product a particular proficiency, the manufacturer is obliged to go through a certification system in the State Standard, where the doors are screened for resistance to burglary and bullet resistance.

door, held a similar certification, of course, will cost more than the usual, and the price difference can be quite noticeable.
