The second task of the entrance door is to protect from cold and heat, as well as extraneous sounds. At the entrance of a multi-storey building a lot of talk. Private houses by the road are located in the zone of increased noise background from transport. Street doors are exposed to high and low temperatures. To protect the interior from these negative factors, the canvas is equipped with a special layer of insulation, and sealing materials are fixed on the contour of the barrel.
But the front door can not only serve as a barrier for intruders and protect from the cold. In such products is laid and the design role. Depending on the type of materials, surface plates and designs, the sash can give solidity to the company and successfully combine with the color of the walls or the surrounding area. Glass cloths have a pulling and disposing influence, because visitors even before the passage see the interior. Wooden doors add warmth to the design of the facade, and metal fabric ensures reliability.Plastic sheets are easy to maintain and do not weigh down the use of the structure with a large flow of visitors.
To perform all the listed tasks, the entrance doors must be well made.

Types of entrance doors
Despite the general functions of this product, entrance doors can be divided according to the materials of manufacture and purpose. Understanding these features narrows the product search area.
Metal doors
The main feature of steel doors is the execution of the box and the frame of the profile pipe or solid sheet by bending. Mandatory elements is an iron overlay panel on the front side of the canvas. Such designs are very versatile: they can be placed in offices, houses, apartments and other public institutions. Depending on the thickness of the metal and the finishing materials, the cost of production and its appearance also change. Therefore, you can choose both cheap and very expensive options.

Wooden doors
This category of doors is lightweight, due to the manufacture of pans and frame frames from the door array. Most often they use pine, but there are shutters of hardwood (oak, ash). The space is filled with MDF framed inserts or milled plates. Finishing is carried out by stain and varnish opening; rarely used obtyagivanie dermatin. Due to reduced anti-vandal properties compared to metal, such products are installed in apartments where the entrance is protected by an intercom or a concierge is on duty.

The product may have a fully glass plate, to which the hinges or canvas, edged profile. In other cases, these doors can look beautiful at the entrance to the cottage, subject to the vestibule and the second door of the tree. For strength, the material is quenched, so it is difficult to break it, but if this happens, the glass breaks up into several parts without small fragments.

Entry door selection options
In order to properly select entrance doors for commercial or private use, it is necessary to take into account important factors affecting suitability in specific conditions. The most important are the criteria described below.
Select by size and shape
Regardless of the type of design you like, you need to correctly determine the size of the door to be bought. Most of the input products have standard parameters 2000x900 mm or 2100x850 mm, which is suitable for apartments and houses. If the removal of the width and height of the opening occurred independently, it is important to take into account the need for a mounting gap of 10-20 mm in order to correct the slope of the box and set it vertically and horizontally strictly. If ludka came close to the opening, the canvas may not close or rub.
An important role is played by the shape of the door. With an opening width of more than 1100 mm, it is recommended to put a double-sided construction, where one sash will be the main (900 mm wide), and the second plays a supporting role and opens only when necessary (furniture carrying, large group of people). For schools and hospitals with high attendance, it makes sense to install two equivalent flaps, which are constantly functioning at the opening. This will avoid congestion and congestion of visitors at the entrance.
Anti-vandal properties
Due to frequent thefts and hacks, most buyers pay a lot of attention to the anti-vandal properties of doors. For this is the box and frame design. The tree is suitable only for an apartment installation at the entrance, equipped with an intercom. PVC profile is sufficient for schools and hospitals where guard is on duty. The glass can be broken by a heavy object, so good alarms or security guards are needed inside.
Metal doors have the highest degree of security, but there are differences here too. The frame of the welded profile is inferior to the bent box from a single sheet. The important role played by the thickness of the steel on the canvas and frame. For apartments, where there is less opportunity to make noise with an instrument, metal thickness of 1-1.5 mm is suitable, and for private houses and cottages it is worth choosing among 1.5-3 mm.
To prevent hacking, manufacturers install additional linings in the area of locks, where the thickness of the steel reaches 6 mm. This is especially practical for remote buildings (cottage, forest house). All doors are designated by anti-vandal characteristics in classes of burglary resistance, of which there are four (for domestic use). Class 1-2 is suitable for entrance doors to a warehouse or utility room, and a value of 3-4 is more acceptable for housing and commercial real estate.
To the canvas could not be removed by cutting canopies, install anti-pins. They are attached to the end of the sash and go into the tank with a closed vestibule. If the loops are cut off, the pins will not allow the blade and the bolt to be removed from its place. It is advisable to have it in remote locations where robbers can wield a loud cutting tool.
Insulation
In order to prevent the penetration of cold and sounds, the canvas is sealed from the inside with various materials. The cheapest is foam and corrugated cardboard. Such insulation is suitable for apartments with warm entrances. Doors that go directly outside, it is desirable to insulate with mineral wool or polystyrene foam. Wool has a density indicator: 10-15 kg / m3 for warm regions and 20-35 kg / m3 for a cold climate. Expanded polystyrene is poured directly into the cavity of the web and gives the best insulation, which makes it universal for any conditions.
Glass doors are not insulated, so they require a vestibule and a second door or air barriers. But the contours of the seal, which is responsible for preventing drafts by means of a dense porch, are placed in all structures. For gluing each line of sealing rubber, a step is needed in the design of the box or the end of the blade. 1-2 apartments are enough for apartments and public places, and 3-4 rows are desirable for houses and cottages.
Weight
The mass of the product affects the attachment points and usability. Doors weighing 40-60 kg will be light for all age categories, so plastic is the most optimal in children's institutions and hospitals. Metal constructions of 60-80 kg are practical for private housing, where there are elderly and children.
Doors of 100–150 kg make plowing the sash heavier, which complicates the entry process for some users. Putting them in apartments and houses is advisable for middle-aged people. Still such products need to be fixed in walls with a thickness of more than 400 mm. With a smaller section of the masonry design can fall out entirely with the barrel.
The higher the weight of the doors, the greater the load on the hinges. Therefore, when choosing heavy models of 100-160 kg, it is necessary to look at the presence of three sheds. Two loops will not cope with such weight and welding will crack. Inside the hinge device for heavy doors, it is important to have bearings and balls for a smoother and easier opening. Wooden and glass constructions usually cost two canopies.
Locks
Locking devices play an important role in burglary protection. They are divided into classes, which determines the time spent on their opening with master keys. Still there are different types of lock device: lever and cylindrical. Since apartments are often opened intellectually, it is better to install locks of the 3-4th class with different types of internal devices. It takes 50 minutes to break in, which will attract the attention of neighbors. Combinations of 2nd and 4th grades are allowed.
In private homes, physical force is more often used for hacking, so devices of the 2nd and 3rd classes with a crab system of thrust bolts will be useful. For schools and public institutions with security, two locks of the 2nd class and a different device of the internal system are sufficient.
Design
This option is chosen based on the facade of the building or decoration in the hallway. But it is important to consider not only personal tastes. Here plays a big role view coatings. Glass and plastic are well tolerated sediments, but the latter can be deformed from direct sunlight. Wood and MDF, varnished, retain a beautiful view, but require a visor over the entrance at the threshold.
Veneer is cheaper than an array, but more expensive than a conventional pressed plate.It is based on pine, and the surface is sheathed with segments of small MDF. Framed frames add elegance and variety. Here the choice depends only on the taste of the user.
The metal is the most durable and resistant to frost, and for its protection a high-quality polymer coating is required - in this case, installation directly on the street without a canopy is allowed. Laminate is easy to clean and is cheaper than an array, but it can crack when it is wet, so it is suitable for installation in apartments. Decorating with leatherette contributes to the weatherization of the structure, but this increases the risk of arson of the blade or cuts from vandals, therefore installation is advisable only in a locked entrance.
Peephole or window
A partial decorative window in the canvas is capable of providing partial security. For its protection, wrought weaving is inserted. This is practical for private homes and cottages. In apartment doors it is better to mount a peephole with a 180 degree view. Glass doors are suitable for installation in crowded places where there are many passers-by and there are video cameras, otherwise the temptation for hooligans is great to just break a large piece of glass. Window inserts in plastic doors are convenient in schools and hospitals, since they make it possible to see the presence of a person from the opposite side and to prevent an accidental blow by a sash.
What is the best door to choose
By classifying products according to the main areas of use, you can select the key parameters of each product:
1. For private houses and cottages suitable metal door with a steel thickness of 2-3 mm, lever and cylindrical lock 3rd and 2nd classes. If there is a visor over the entrance, then you can choose a model with an array of wood or MDF overlay. If there is no canopy over the entrance, then it is better to buy the product with powder coating. Mineral wool or polyurethane foam and three sealant circuits are required as insulation.
2. For an apartment with a secure entrance, a wooden door with MDF or veneer will be suitable. In all other situations, metal thickness of 1-1.5 mm, two locks of the 3rd and 4th classes, a peephole by 180 degrees, two seals of the sealant and foam insulation are recommended.
3. The entrance to a solid office building should be equipped with metal doors with a steel thickness of 2 mm, milled MDF slab, two locks of the 2nd class and three sealing contours.
4. For restaurants and cafes, glass double doors with a thickness of 5 mm or more will be attractive, with two contours of the compactor and hidden locks in the floor of the 3rd class.
5. It is recommended to equip schools, hospitals and dormitories with plastic doors with glass inserts and a camera with mineral wool insulation. Enough two locks of the 2nd class.
How much is the front door
Knowing the key parameters for different places of operation, we can distinguish the range of prices for these products:
1. Doors for homes and cottages with thick iron will cost from 11,000 to 20,000 rubles.
2. Room options cost 6000-10000 rubles.
3. Solid designs in the office have a range of 15,000-25,000 rubles.
