With the onset of cold weather, the problem of drafts in the apartment becomes especially relevant. After all, no matter how hot the batteries are, a draft will still draw out all the heat. A warm front door is an important part of maintaining heat in a residential area. Consider what can be done so that the front door provides good protection not only from strangers, but also from drafts.
If the door is very old, it can simply be replaced with a new one. Ideally, a full double. The double door unit consists of one box, to which two door leafs are attached at once. Such a block does not occur often, but in vain. A double door should not be confused with a double door, they are completely different things. A new door with a double block is, of course, good, but not always possible, and not always necessary. What else can be done? Put a second door, very simple, thus creating a small vestibule. Many have done this in the past. It can be installed both outside and inside. The main thing is not to forget about the threshold and compaction. (Recommend cartons for packing)
Deformation
If a draft is felt around the perimeter of the door, then you need to eliminate the gaps between the dense door and the door frame. To do this, a foam or rubber seal is sold in specialized departments of the store. Self-adhesive rubber will be more practical. The gluing technique is the same as for the window seal: clean and degrease the surface and stick the seal. You can apply a double blow to the draft — stick the seal on both the door frame and the door itself. An important point: both seals — on the door and on the door frame should fit snugly against each other. It will not be superfluous to check the serviceability of the fittings, because the door can simply sag due to loose screws or deformed hinges. Everything that is loose will need to be tightened, and the deformed one will need to be replaced. The door itself may also be deformed. If the wooden door is swollen with high humidity and stops closing, you can simply cut it with a planer.
If it comes through from the gaps between the opening and the door frame, you will have to replace the worn seal. To do this, you need to remove the door slopes, remove the remaining old seal, fill the existing space with a new one (as a rule, mounting foam is used as a new seal) and return the slopes to their place.
If it blows from the door itself, it can be insulated using heat-insulating materials. Previously, they used cotton wool, synthetic winterizer or foam rubber. Currently, you can use modern heat-insulating materials — penoizol, isolon, foamed polyethylene. Well, if the insulation is heat-reflecting, if not, it would be wise to use a metallized film. Decorative upholstery is necessarily attached over the sealant — vinyl, eco-leather, leatherette.
In a metal door, you can fill the existing internal voids with heat-insulating material. As a heater, you can use corrugated cardboard, mineral wool, polystyrene foam, foam rubber, expanded polystyrene, foamed polyurethane. To do this, install embedded bars (a decorative panel will subsequently be attached to them), we foam the gaps between the metal and the embedded bars, lay the sealant and foam the remaining gaps, let the mounting foam harden, remove the excess, put the decorative panel in place.
It is not so important whether the front door is new or old, it is important that it protects the interior from any unnecessary penetration — no matter whether it is an annoying salesman or an equally annoying draft.
