If a drafts began to form in your apartment, and an unpleasant smell is searched from the entrance, then this suggests that your door needs a seal. Moreover, this problem is characteristic of metal door structures. To fix it, you must select the seal to choose and make it install.
Today is a fairly wide range of seals, which can be used for a metal door. All of them differ in the material that was used during their manufacture.
Rubber
Most often, seals made of rubber use the sealing of the metal door design. This option is suitable even when the door goes straight to the street. The presented method of use is associated with the specific properties of rubber. The composition has modified additives, due to which the product is perfectly adapted to weather conditions, even the most severe.
Rubber The advantages of the rubber seal should include:
- long service life;
- increased resistance to environmental influences;
- high elasticity, thanks to which it is possible not to worry about the formation of cracks;
- waterproof;
- low price.
Today, you can find a rubber seal with a self-adhesive basis. Thanks to him, the installation process is facilitated many times, as it is not necessary to spend additional funds for the purchase of fasteners.
Silicone
The sealer for the metal door made of silicone, according to some indicators, is inferior to products from rubber. For this material, elevated elasticity is characterized, so the installation of the seal can be carried out on the surface of different textures.
Silicone But the disadvantage of silicone products is the absence of the possibility of upgrading the composition by special additives, due to which it would be possible to slow down the destruction of the structure of the floor with the influence of moisture, sun rays, leakage of temperatures. Thus, silicone products extremely rarely use in order to seal outdoor doors.
Porolon
The foam rubber seal is a budget option. As a rule, it is used when calculating the service for one year. Unfortunately, with the constant application of the door for longer period, the specified product is used irrational. If the foam sealer is already old, it will begin to decay and crumble.
Foam seal This happens for the reason that the foam rubber is not capable of providing proper disappearance of moisture and jumps of temperature. Over time, the material is knocked down in whom, loses its former elasticity, as a result of which it is not able to cope with the tasks assigned to it.
Polyurethane
Seals obtained from this material have pretty good performance. Their main advantages are simplicity of installation and long service life. But at the same time, polyurethane has a low resistance to abrasion. So it is not worth using such a seal on the doors that are in constant use.
Polyurethane type of seal Plastic
Plastic seals have elevated sealing properties. Many of these products have a hollow internal structure. Due to this feature, it is possible to obtain an additional seal contour as an air layer along the edge of the door design. Thanks to it, thermal energy is preserved.
Plastic seal Plastic products have an affordable cost, but the process of their installation can cause certain difficulties. The reason is that the compactor must be mounted in the groove. From here it is necessary to choose products individually according to the constructive features of a certain door.
How to replace the seal
If over time you find that you have extraneous smells, sounds and drafts in your apartment or house, then the seal was most likely caught. Its replacement can be performed by itself, but only after it is correctly selected. Today, these products can be mounted in two ways: in the groove or on the self-adhesive foundation. Of course, the second option is preferable. But here it is necessary to choose the seal of the required thickness and the corresponding profile.
For these purposes, you can use a proven method: take a piece of plasticine, wrap it in polyethylene. Then install between the frame and the door web. Now the door is tightly closed. Open it again and remove the resulting pattern, which will allow you to determine the thickness of the seal.

The replacement of the sealer is extremely simple. We need to remove the protective film with the sticky side and close the product to false doors. If you do everything right for the first time it did not work out and after a while the sealant began to dug out, then you can use glue momentum for installation.
What is suitable for Chinese metal doors
For waterproofing the metal door design of Chinese production, today began to actively use the seal obtained from a microporous rubber with a groove. It is he who performs its sealing tasks by 100%. As a result of its installation, it is possible to obtain reliable sound insulation and thermal insulation, maintain comfortable conditions indoors.
The rubber seal guarantees the creation of hermetic compounds that will not pass moisture from the air inside the house, as well as produce heat to the street. Thanks to the microporous rubber ribbon, it is possible to securely fill the construction joints.
The high elasticity of the rubber seal allows its installation on curvilinear and geometric non-standard connections. It is perfectly stretched and its operational qualities are not violated.
The main advantage of this seal remains resistance to mechanical influences, solar rays and wear. When using a rubber sealing tape does not cause allergies, since it does not use heavy metals, solvents, acids and harmful substances during its development. When using this product, the possibility of destruction of the door design is completely eliminated.
Choose a seal for a metal door today is not a problem. The main thing is that the selected product is suitable in thickness and could withstand negative conditions arising during operation. If you are not sure that you can perform the installation qualitatively, you should not experiment, it is better to trust this business professionals.
