What to do to prevent the apartment from heating up in hot weather? Especially an apartment with windows in the attic.

A lot of heat comes in through the windows. There are blinds that reflect the rays, metallised blinds. You can also make your own home reflective screen. I once did one with Alutherm QUATTRO. It insulates well.

You need to use insulators especially for windows (blinds, special films) you can also use an air conditioner ;)

I solved this problem by installing a canopy on the balcony, because that's where I get the most sunlight. A simple piece of material effectively reduced the temperature of the entire apartment. Therefore, you can safely try with shutters, they should do the job. Just remember to paint them white to reflect the light.

a very good idea is an air conditioner, but a professional one that will be installed by a specialized installation company. In winter, you can warm up then, because such an air conditioner has a heating function - reverse. It is connected to electricity and the bill will jump because of this, but in principle this solution will mean that you can close other sources of heat / cold, e.g. a gas stove. I highly recommend it, because I have it and the problem is solved 100% I'm sitting in the heat at a temperature that suits me.
Each of us has different preferences regarding the temperature, so I recommend you BEKO with installation in installments in media markt I bought PLN 2,000. The Split type BEHPI 090/091 meets the needs of all people, offering 5 modes set with the remote control from the sofa: Turbo, Max, Mid, Min, Auto and the cooling power of 2.7 kW.
With such strength, you can easily fight the heat even in large rooms, such as the dining room combined with the kitchen. Split BEHPI 090/091 also works great when it comes to heating. 2.4 kW of power allows you to ensure high temperature even in winter - the air conditioner can work even in frosts down to -15 ° C.
The Auto mode allows the air conditioner to take care of the proper rhythm of operation on its own, of course, you can also change the settings yourself. A temperature sensor is installed, which determines the airflow strength in auto mode.
When you're at work or shopping, you have the HomeWhiz app to control your air conditioner from your phone.
Connected to the home Internet via Wi-Fi, the air conditioner and heater in one will take care of preparing the perfect temperature for returning home,
The SelfClean+ self-cleaning mode is a set of filters and corrosion-resistant, gold-plated blades that extend the life of the device, saving you both worries and money. I wrote you off the warranty, but it's been half a year with me and I have a great comfort of living and working.
Such an air conditioner is designed for a room of about 24 m², but you can do it for the whole house. The electricity bill has doubled and is now instead of PLN 500 - PLN 900, but I turned off the gas stove heating in the whole house, which consumed gas on average 2,000 a year. monthly. Now we only heat the water. We are super pleased. Costs per year fell by 50%. I highly recommend you and I leave the choice of Beko or Philips to you and the installer.
cordiality and like please.

The problem of roller shutters that are mounted inside the room on the window is the accumulation of heat (tested both metallized and ordinary). The solution turned out to be a special external mirror foil that reduces UV, reflects heat and reduces sunlight. This season, I mainly install such foils for my clients. The temperature in the room drops on average in the range of 6-8 degrees less. Please note that you can find such foils for application from the inside - do not do it on double-pane chamber windows - because the reflected energy increases the pressure between the panes and can lead to unsealing of the chamber and even glass cracking, it is recommended only for single-pane windows.

In the first place, close the windows during the day, and only open them at night + install blinds / blinds / shutters that will reflect the light. Worse, if it is not the windows that are the problem, but the poor thermal insulation of the roof - then whatever you do with the windows, the heat will escape in the winter and it will be hot in the summer.

The attic should be insulated. Thermal insulation insulates us from the cold in the winter and from the heat in the summer.

To reduce overheating in the apartment during hot weather, especially in the case of an attic apartment, several natural methods can be used. Wooden shutters can be an effective solution as they block direct sunlight and help maintain coolness in the room. Closing windows during the day and opening them in the evening when the temperature drops is also an effective method. Other proven methods include using thermal blinds to cover windows, placing leafy plants outside windows to absorb heat, and using window draught excluders to prevent warm air from entering the interior. For best results, it is worth trying several different solutions simultaneously. This way, overheating in the apartment can be effectively minimized without the need to use electrical devices such as air conditioning or a fan. It is also important to remember to regularly ventilate the rooms in the evening and in the morning when the temperature is lower.
