Balcony door upholstery
This method allows you to solve two problems at once: to insulate the door itself and to close the gaps along its perimeter, which are the main cause of drafts. A detailed description of the door upholstery (see the front door upholstery) is literally on every “door” website, including ours, so we will describe the process very briefly.
So:
- Remove the door from the hinges, unscrew the knobs, bolts and other accessories, put the outer side up on a flat surface.
Council Warming the balcony door is best done from the outside, so that it is not visible from the room and does not violate its design.
- Foam and rubber make three rollers - one long on the feigned side of the door and two short ones for the top and bottom. Nail them with construction nails so that the rollers overlap the gaps between the door and the box.
- Secure the cut-to-size piece of foam rubber to the blank bottom of the door with a stapler., on top of it with nails fasten leatherette.
It remains to replace the handle first, and then the door itself. But we only insulate the lower part and the perimeter of the door, but what if the standard double glazing doesn’t save us from the cold?
One of the options is to stick a heat-saving film on the glass, which reflects the heat back into the house and transmits light into it. It is attached to a double-sided tape, and after installation is almost not noticeable.
Additional glazing

The third glass is an excellent insulation for a balcony door (see How to insert glass into an interior door). It will not only improve the insulation, but also reduce the level of noise entering the apartment.
It is installed on the frame from the inside, where there are protruding edges of the bindings:
- Cut the glass to the desired size.
- Glue the sealant (a strip of foam rubber or felt) around the perimeter of the mount.
- Press the glass to the seal and fix it with small studs hammered around its perimeter.
- Treat the gap between the glass and the frame with putty.
- Finally fix the glass with beadings or metal pressure plates, fastening them with self-tapping screws for easy dismantling.
- Paint the beadings in the color of the frame.
We warm the interdoor space

The easiest thing is to buy a foam plastic of the desired thickness, equal to the distance between two balcony doors, and install it between them. If you have absolutely no desire to spend money, insulation can be made from old newspapers.

So:
- Lay 3–4 unfolded newspapers on top of each other and roll them into a roll, the diameter of which should be slightly larger than the distance between the doors. Glue the edge so that the roll does not turn around.
- In the same way, make the necessary number of rolls so that, set vertically in a row, they equal the width of the balcony opening.
- Stuff each roll with crumpled newspapers.
- Collect all rolls in one block, pasting them on all sides with expanded newsletters. Do not forget to seal the top and bottom holes of the rolls.
- Install a self-made insulation between the balcony doors. It will keep warm well, and if necessary go out to the balcony it can be easily cleaned.
Again, in this case only the lower part of the door is insulated. To prevent cold air from entering the room through the glazed top, the joints between the frame and the glass can be glued with a cloth or paper strip moistened with soapy water.
The dried soap solution doesn’t let through drafts at all, but if you don’t want to mess with it, buy a special adhesive tape for warming windows.
