Sealer for interroom doors: species and features

Protect the room from moisture, dust and extraneous sounds help special designs. The sealer for interior doors provides silent operation, since the main canvas does not hit the box.


Usually seals are not installed on all doors in the residential room.

Most often need additional noise, moisture and dust the following rooms:

  • children’s;
  • kitchen;
  • bathroom;
  • toilet.

Special door structures reliably hold unpleasant odors and suppress noise that can interfere with rest or sleep.

High-quality insulating material for door canvases must have the following characteristics:

  • High tightness;
  • Do not interfere with the smooth move of the door canvase;
  • good resistance to temperature differences and humidity parameters;
  • be environmentally safe;
  • Do not represent the threats to the health of people and animals;
  • have a high indicator of elasticity, quickly rebel.

All modern insulation materials meet the stated requirements, reliably performing their functions.

For interior doors, the door seal is applied softer and elastic than for input structures. Otherwise, the door will be difficult to close, which will ultimately reduce its life.

Some interior doors already have insulating elements, but sometimes it may be necessary to independently install the seal.


To pick up optimal insulation for interior door, you need to know their types that can be used inside residential premises.

The following types of seals are popular:

  1. Self-adhesive. This species is easy to install, even a person will cope with it without experience in the installation of door insulation. It is a ribbon that has a sticky basis, removing which you can easily attach the seal to the canvas or the door of the door.
  2. Magnetic. Can be used only on metal doors. They are reliable, easy to mounted and dismantled, the installation does not require possession of special skills and tools. Most often they are installed in bathrooms and toilet, as they have the highest tightness indicator.

Also, the purpose of the door isolation has considerably.

For this parameter, the seals are divided into the following types:

  1. Contour. Installed around the perimeter of the door box. Allows you to achieve high sound insulation. In addition, the door leaf with the contour seal does not knock when opening-closing about the box.
  2. Threshold. Installation is carried out in a special recess. The groove is at the bottom of the door frame. One end of the insulation of this type ends with a deaf end, and the opposite – a special device that activates the groove seal when opened the door.
  3. Fireman. Used for temporary (depends on the model and manufacturer) the insulation of the room in which the fire occurred. Most often is made of foamed materials, which, when increasing the temperature, expand, reliably sealing the room in which the fire. This type of insulation reliably protects other rooms from smoke, fire and toxic combustion products.

The choice of the necessary type of interroom seal depends, first of all, from the necessary characteristics of protection and material from which the door leaf is made.

Some types of insulation are not used for wooden products, others – for plastic, metal, or glass.


Seals for interior doors can be made from various raw materials.

Most often can be found in the sale of insulation from the following materials: rubber (polyurethane), silicone, foam rubber, brush tape.

  • Rubber models – most popular, they appeared on the market alone. Made from oil and acid-resistant raw materials. These seals are available in price, have a long service life, racks for the formation of cracks.

High moisture and aeronautability allows you to use insulating material from rubber in any rooms, in interroom and input structures.

  • Silicone seal is often used as insulation for interior glass doors. Thanks to special additives that increase the durability of primary raw materials, this type of door pads serves a long time, but does not have high protection against aggressive detergents and acids.
  • Foam seal – the most budget of existing. Its main minus is a very small service life. Due to the porous texture under the influence of the environment, he begins to crumble and soon comes to disqual. With intensive operation, it quickly loses its elasticity, it is reduced, as a result of which its protective properties are sharply reduced.
  • Brush seal It is used for the door and allows you to protect the room of the room from dust, moisture and noise thanks to a porous surface. Very easily mounted, as it has a sticky basis.

Thus, in order to correctly select a seal that will last long, you should give preference to models made of rubber or silicone.

Installation Tips

Installation of the seal on interior doors can be carried out in several ways, which depend on the type of insulation. The most popular way is the installation of self-adhesive models.

The sequence of actions is as follows:

  1. The surface is prepared. For this, the degreaser and soft fabric is used. It is very important to completely remove dust and fine garbage, otherwise the quality of gluing will be extremely low.
  2. The protective film and the product is neatly removed from the sealer and the product is attached to the right place. It is better to glue a self-adhesive seal with small segments, gradually removing paper protection as needed.

In order for sound and moisture insulation to be higher, both sides should be sampled, as well as the bottom and top of the door box.

To set the insulation of the interior door using the technology “in the groove”, no special skills will also need, and from the tools – only a sharp construction or kitchen knife. Special attention is paid to the neat trimming of the seal in the corners. After the installation is completed, the excess insulating material is cut off with a knife.

Some seal models do not have special fasteners and are fixed on the door leaf with silicone glue.

It is very important when installing silicone or rubber insulating material not stretch it, as this will reduce the technical characteristics of the product and the level of protection.

In apartments and private houses, it is often necessary to compact the connection of the box and the door leaf in order to protect the room from noise, moisture and extraneous smells. With this task, modern insulating materials are easily coping with, which are easily mounted, perfectly copble with the tasks assigned and differ long service life. A wide range allows you to choose the optimal option of the sealer at any door and in any room.
