If suddenly in the house or apartment there was a feeling of a draft or street or driveway smells began to be felt, then this indicates that the door has ceased to close tightly. You can solve this problem on your own by purchasing door door seals.
Entrance doors often upset their owners, unable to cope with their main task - maintaining heat in the room. The inside doors can be filled with insulation, but if they do not fit snugly on the door, they are ineffective and play a minimal role in maintaining the internal microclimate.
What are seals for?
The door seal for doors is used for tightness and density of the entrance opening with the doors closed. For each door, the seal must be searched for personally. A thick sealant will not allow the lock to close normally, and a thin one will not save the room from a draft and external noise, since the doors will not fit snugly against the jamb. It is glued around the perimeter of doors and loot.
Sealant for doors and its varieties
Sealers are made by many companies from high quality and not so materials. Each of them has its own characteristics:
- Production material - rubber, foam rubber, silicone, plastic and others.
- Type of product - the seal of the doorway can be solid, made of one material or pressed with a metal bar.
- Mounting method - some are self-adhesive, while others are attached with screws or self-tapping screws. The latter view is placed only on wooden entrance doors.
Most often, for metal doors, self-adhesive sealants are used, which can be purchased in the form of a tape. For one standard doorway, six meters of self-adhesive sealant is enough.
How to choose a seal
The door seal is self-adhesive, its type and type are selected depending on the width of the gap in the doorway. For the gap in the doors with a width of 1-4 mm, a rectangular sealant made of PVC or foam rubber is used. However, it is better to use rubber seals in the form of various Latin letters for metal entrance doors . They are more reliable and durable, and are also designed for sealing backlash widths from 1 to 7 mm.
Rubber door seal is of the following types:
- C-loop or K-loop. Use to close gaps up to three millimeters.
- P-loop and V-loop. Used to cover slots in size from three to five millimeters.
- O-profile or D-profile. Such seals are installed if there are about seven millimeters gaps between the box and the doors.
The door seal for doors is available in various colors, allowing you to choose it for the color of the door. The most common colors for exterior doors are black, white and brown. However, most experts emphasize that the dyes used in sealants for street entrance doors, when exposed to the environment, reduce the quality of the rubber product. Therefore, experts advise putting black, or in the extreme case, brown sealant on such doors.
The main requirements for sealing material
The main parameter of quality installed doors is their tightness. It is this property that buyers should pay attention to. The front door must protect the room from heat leakage, cold and moist air seeping, dust and noise from the street into the house and penetration into the home of street or drive "aromas". Also, the door must be securely closed.
All these characteristics depend on the quality of the door seal on the door structure. Therefore, all varieties of rubber seals must have an appropriate standard for moisture and air, and also have good elasticity when closing the door.
The rubber door seal must not lose its elasticity when the temperature drops or lag behind the surface. In all weather conditions, it must retain its properties and qualities for insulation and sealing of the doorway.
Seal for doors self-adhesive. Material setting
On modern metal and plastic doors, manufacturers install a special seal, which can last from several months to several years, depending on the cost of the door leaf: the more expensive the door, the better the seal. On the cheap exterior doors are low-quality plastic seals, which will soon become unusable.
It is not difficult to install a self-adhesive door seal for doors on your own - it is important to choose the right thickness of material and its profile. To do this, you can apply the method used by our fathers and grandfathers: wrap a piece of plasticine in polyethylene, put it in the slot and close the door tightly. After opening the door, the approximate thickness of the future seal will be obtained with the doorway closed.
Material Installation Tips
The door seal for the doors is fastened quite simply: before installing the material, it is necessary to degrease the fastening place, then the protective film is gradually removed from the material from the sticky side and pressed tightly against the door fold. Some manufacturers save on adhesive for sticky surfaces, and such a sealant soon begins to lag behind the door. To remedy this situation, you can use quick-drying glue, for example, “Moment” or “Second”.
Output
Summing up all of the above, we conclude that the door seal is the tool that can save a house or apartment from the penetration of alien sounds, smells and drafts from outside. This is even more true for cheap doors, which are often sold without a seal or on which there is a cheap sealing material that quickly deteriorates.
Sealers are different in workmanship and appearance. Each of them is intended for closing door gaps of different widths. Therefore, before installing the seal, you should determine its profile, so that later you do not have to reinstall it.
Sealers come in different materials: rubber, foam, plastic and so on. Rubber is considered the most common, as they are more durable, better and more reliable. They are easy to install on doors and door frames and just as easy to remove. The most important thing to remember: before installing the material, it is necessary to remove debris, dust and degrease with a solvent or alcohol the surface where the sealant will be glued. Otherwise, it will necessarily come off during operation, and you will have to buy a new one.
Experts also advise not to chase color seals, because due to the added color pigment, it loses its qualities under the influence of weather conditions.
