Let's not let the draft into our house! Do-it-yourself front door insulation

As you know, there is nothing superfluous in home insulation. Floor, ceiling, walls, windows - everything must be thoroughly insulated if you want your apartment to be comfortable. And door insulation in this situation is no less important concern.

Drafts from your front door can be a nuisance. Any construction: wooden, metal, - by itself does not save from cold weather. Therefore, additional door insulation is required.

How to do all the work correctly so that the door will faithfully serve to preserve warmth and comfort in your home for many years, we will tell you in this article.

Ways to insulate entrance doors

If the manufacturer has provided for the thermal insulation of the door, then you do not have to make much effort, because the layer of insulation is already inside the structure. But most often we buy a regular, standard door leaf, since it is much cheaper.

How tightly you need to insulate your door depends on what material it is made of. As a rule, doors are:

• metal;
• wooden;
• plastic.

To isolate plastic blocks, tools and special skills are required, in this case it would be more correct to turn to the services of professionals. But a wooden or metal door is easy to finish and insulate with your own hands.

The best option for insulation may be the installation of a second door. Thus, a small vestibule with an air cushion is created between the entrance and internal doors, which will slow down the heat escape from the room, and at the same time will not let the cold outside.

In addition, any gaps around the door frame should be repaired - it is through them that the cold penetrates into the room. To do this, it is enough to use polyurethane foam.

You will also need to use a seal. The more loads it can withstand, the better, because doors have to be opened and closed often. This material is presented on the construction market in a wide range. Sellers will help you choose the most suitable one for your door.

If your apartment is on the ground floor, it is better to immediately attend to the fact that the entrance door closes automatically. To do this, you can install a closer. An agreement with the neighbors about the intercom will resolve this issue thoroughly.

Insulation of the front door with foam rubber

If you want the insulation of the front door not to take a lot of your time and money, use the most familiar, common material - foam rubber. It is not suitable for sealing on the sides of the door frame, but it can be sewn onto a wooden door on both sides.

To work, you need the following:

• Foam rubber;
• Upholstery fabric;
• Glue;
• Threshold board;
• Slats made of wood and plastic.
• 1. First, cut off the obsolete covering from the door and dispose of any remaining insulating material. Wash the surface thoroughly.
  2. After the door is dry, glue it on the inside and outside with layers of foam rubber, cut strictly to size. If necessary, pieces of foam rubber can be glued in 2-3 layers (for example, if the material is thin, or you think that additional insulation will not harm).
  3. Now stretch the upholstery over the foam, securing it to the door with nails or a construction stapler. You can decorate the surface with a pattern made of wallpaper nails. Do not overdo it: the nails are pressed and the insulation is pressed in, because of this, its heat-saving properties are lost.
  4. It was the turn of the door frame. Fill the slats that were previously covered with foam rubber and fabric around the perimeter of the door. At the same time, control the position of the closed door: it should fit tightly, without cracks.
  5. The last stage of insulation is the installation of the threshold. The threshold board should completely cover the gap under the door, but not prevent the door leaf from opening and closing.

Instead of foam, you can use materials such as foam (2 to 5 cm thick) or polyethylene foam. In terms of their heat capacity, they surpass any traditionally used materials.

Such a simple and economical way will help you quickly insulate the door, additionally protecting you from extraneous noise.

Insulation of metal doors

Metal doors can create so-called cold bridges. Through them, frost makes its way into the room, even if the door leaf is completely sealed and closes tightly. Therefore, the purpose of insulating a metal door is as follows:

• increased door sealing;
• insulation of all metal parts of the product, except for the door handle;
• placing the insulating material inside the door leaf.

Almost all metal doors are hollow. Thanks to this, it is very easy to place mineral wool or a foam board inside as an insulating material.

So, the process of insulating metal doors will look like this:

1. Remove locks and door handles carefully;
2. Disassemble the box (if the fastening is carried out with welds, they must be removed with an angle grinder);
3. Lay the insulation inside the empty box;
4. Assemble the door structure to its original position.

If you chose polystyrene for insulating the door, then there will be gaps between the sheet and the fixing-fixing metal profiles. In order to ensure complete thermal insulation, fill these spaces with polyurethane foam.

If you have a non-separable door, it can be insulated with an internal additional cover. To do this, remove the door from its hinges, remove handles, locks and other adjusting fittings. On the perimeter of the door leaf from the inside, screw a beam with a diameter of 10 X 10 mm, stretch the upholstery for the entrance doors and fix it on the beam with special nails.

What if additional insulation is not enough?

A well-insulated outer door should not allow a single gram of cold air to pass into the room, as well as not release heat outside. But you can face the fact that you seem to have done all the work correctly, but the expected result was not achieved. What could be the reason?

First of all, pay attention to whether the door leaf was correctly positioned during installation, and whether there are any gaps in the polyurethane foam. Both reasons equally lead to a violation of the sealing of the entire structure.

To determine the quality of the foaming and find the gap, use the traditional folk method: light a candle and slowly move along the joints of the door frame. Even the smallest draft will begin to vibrate the flame, thereby pointing you to the remaining gap.

In order to properly adjust the door leaf, you need a set of hexagons and socket wrenches.

Adjustment is carried out due to awnings, of which there are usually 4-5 pieces on the door. Each canopy is secured with a locking nut and four bolts. Adjustment work is carried out as follows:

• lower the adjusting nut on all hinges;
• lower the bolts with a hexagon and level the canvas;
• tighten the bolts and fix their position with a nut.

Unlike works on insulation and installation of doors, adjustments can be made in any weather conditions, but severe cold can cause additional adjustment of the awnings in summer.

We insulate the door leaf around the perimeter

No matter how well the door leaf is insulated, no matter what materials you use for this, the work will be insufficient if the door does not fit tightly to the box.

Gaps between the jamb and the door arise in the event of installation errors, or after some time due to building shrinkage or structural distortion. The sealant will help to solve this problem quickly and easily. It is enough to fit it tightly to the door frame, and the structure will become completely sealed, all gaps will be filled, and, accordingly, the heat loss of your house or apartment will be significantly reduced.

1. The modern building materials market offers a large selection of seals. The best option is rubber tubular seals with a self-adhesive base.
2. In order to choose the required width of the seal, focus on the width of the web. Its thickness when compressed should be equal to the width of the gap between the frame and the door.
3. The thickness of the seal also requires special attention. Too thin material is not effective enough, and too thick will cause inconvenience when closing doors.

Insulation work with a sealant is quite simple: remove the protective film and glue the seal around the entire perimeter of the canvas. If your seal doesn't have an adhesive backing, use liquid nails or silicone.

Do not forget to check the integrity and condition of the door frame. If it is rotten, replace it before insulating the door. If you mounted the box on foam, check if it has crumbled.

As you can see, independent insulation of almost any door can be done even by a beginner. Share with us and other readers your practical experience in such work, ask your questions, and we will be happy to discuss all comments and suggestions. Warmth and comfort to your home!
