With the arrival of cold weather, it is worth checking whether the insulation of our home is adequate. In addition to the discomfort caused by low indoor temperatures, poor insulation can lead to high overhead costs, so it is worth taking action in time.
It is best to choose an apartment whose walls were provided with thermal insulation from the facade during construction. If this has not happened, you should consider replacing it. However, this investment can be expensive and time-consuming, and you will also need tools and materials, such as a polystyrene cutter or the essential thermal insulation material.

In addition to the facade’s thermal insulation, replacing old doors and windows can lead to practical results.

However, we may need more time to implement the above, or we want a more cost-effective method. Let’s see what cost-effective solutions there are for home insulation!

1. Start with the windows!

In addition to poorly insulated walls, most heat leaves the apartment through the windows. It is worth starting with this if you want to see and feel immediate results. First, we must determine what type of windows we are equipped with: plastic, wooden, or aluminum. After that, the necessary raw materials must be obtained, and the insulation can be started.

Even before we do this, let’s find out where there is a problem with the insulation of our window. A practical way to do this is to walk along the edge of the window frame with a lighter or a burning candle, and where the flame starts to move, there is a high probability that the air will escape.

Rubber seal, foam tape

In addition to being cheaply available, the great advantage of these insulating materials is that they are easy to use regardless of the size of the window. In the case of both the rubber seal and the foam tape, please measure the length and width of the window and the size of the gap we intend to insert.

With the help of the foam tape, we can quickly remedy the problem, as they are self-adhesive so that they can be rapidly applied to the windows. We can also tailor them to size afterward. Its lifespan is approx. 2-3 years, compared to the rubber seal, which lasts up to 7-8 years.

Thermal insulation film

The thermal insulation window film is a self-adhesive sheet that you can stick on the desired surface yourself. When installing it, ensure the window is clean and the temperature is at least 10 ℃. The thermal insulation film adds an extra layer, similar to a curtain or a lowered blind, but all this without impairing visibility. It will keep the apartment cooler in summer and warmer in winter.

2. Wall-protecting quilt or heat-insulating wallpaper

The wall-covering quilt and heat-insulating wallpaper also work on the same principle as the window film. In both cases, we place an extra layer on the wall, which can be used to compensate for poor or incomplete wall thermal insulation. Both can be easily applied freehand, so they promise immediate results. Another advantage is that, in addition to insulation, they can also be used as a decorative element since countless samples are now available in stores.

3. Insulation from below: get a thick carpet!

We often see thick, heavy-looking carpets in the rooms of old buildings and high-ceilinged apartments. Not by chance, since they add a lot to keeping the room warm in addition to aesthetic properties.

If you want to be sure, buy a floor mat! Make sure that the carpet covers as much of the floor as possible. You can increase your desire for warmth by purchasing a thermal insulation pad.

4. Heat-reflecting film behind the heaters

It is an almost classic method, and not without reason. The theory behind its effectiveness is heating the room instead of the outside space. So, if we place the heat-reflecting film, or heat mirror as it is called, behind the radiator, we reduce the chance of warm air flowing out to a minimum.

Which one should I start with?

After you have familiarized yourself with several practical methods, the question may arise: which one should I start with? It is worth considering how big the problem is, how cold it is in the apartment, how much the overhead is, and how much time and energy you have for repairs.

If you want to keep things in your own hands and do not plan to make a significant investment, combine several methods simultaneously, as you are more likely to achieve results. However, if it is clear that, for example, only the aging of the windows is causing you problems, then focus on that area!

The role of thermal insulation in energy consumption

Thermal insulation plays a significant role in the energy consumption of a household. Although it is possible to reduce the overhead costs with the methods described above, if you want to achieve significant, more considerable cost reductions, the complete thermal insulation of the house, including the walls, windows, etc., is unavoidable.

In the case of a house, the walls are the biggest emitters of heat, so if you are determined to insulate, it is advisable to start there. For this, you can choose from various heat-insulating materials. It is worth researching what is best for you.
