To create a reliable insulation of technological gaps between the door frame and its leaf, the seal is replaced. Due to the special elasticity of the materials of manufacture and the specific shape, this product tightly seals the space between the leaves. This helps to improve heat and sound insulation, and prevents the penetration of odors in both directions.
Varieties
Currently, the replacement of the seal on plastic windows and doors, metal structures can be done using a number of special insulating products.
Tubular seals are hollow material with a dense structure. The presence of a free inner layer ensures a tight connection between the door frame and the door leaf. Porous bases are most often used as the material of manufacture. Due to this, the replacement of the seal increases the effect of thermal insulation several times.
Special insulating materials for sealing interior doors, unlike the previous category, have a more pliable, soft structure. This is due to the absencethe need to counteract severe drafts. A typical example is a self-adhesive seal.
Products of a specific configuration for fastening in a groove allow quick replacement of insulation when needed. Mounting features reduce the negative impact on the sealing material from environmental factors. With the help of such tools, most often the seal is replaced on plastic windows and doors. Groove mounting is effective for both indoor and outdoor joint sealing.
Materials
Door seals are also classified according to the materials of manufacture. There are several popular options:
- Rubber products - most often used in the insulation of street doors. Due to the presence of specific modifiers in the composition, such insulating products adapt to the most severe, aggressive operating conditions.
- Silicone - inferior to rubber in terms of performance. The main advantage of such seals are: low cost, quick installation.
- Foam rubber - has a modest service life. Used when the door seal is replaced for one season. Sudden changes in temperature and humidity quickly destroy the material. Therefore, its use looks rational only with an extremely limited budget for insulating a door or window structure.
Features of choice
In order for the replacement of the seal to give the expected result, it is necessary to determine its optimal type and shape. To do this, measure the gaps between the door leaf and the door frame. Experienced craftsmen resort to the use of plasticine wrapped in plastic wrap, which is placed in the slots when closing the porch. Gap parameters are measured with a ruler or tape measure.
To seal gaps 1-3 mm wide, the seal is replaced using a rectangular polyvinyl chloride, foam rubber or polyethylene foam insulator.
In the presence of gaps of more than 3 mm, K-shaped, C-shaped or E-shaped rubber profile products are used. V-shaped, D-shaped and P-shaped seals are used when it is necessary to eliminate significant gaps that exceed 5 mm.
The required volumes of insulating material are determined by measuring the parameters of the leaf and the door frame. The values obtained are multiplied by the number of layers of material sufficient for reliable sealing. It is recommended to purchase a seal with some margin.
Installation
Modern metal doors from well-known manufacturers contain a special profile, the grooves of which require the installation of a seal of the appropriate form. You can buy such insulation in the shops and service centers of the manufacturer.
If it is necessary to seal an old-style structure, you can use self-adhesive insulating material. The main thing here is to correctly calculate the desired thickness andenough layers.
Rubber seal sits on silicone adhesive. To do this, the connecting base is smeared with both the surface of the insulating agent and the door leaf or frame, depending on the installation location.
