External sun shading systems - are they more effective?

<

Interiors that are full of sunlight require effective sun protection. When deciding to purchase them, it is important to remember that external screens are much more effective. They retain heat energy outside, preventing a significant increase in temperature inside the room, while at the same time improving the aesthetics of the building.
In the case of interior shading, infrared waves are converted into heat energy at the sheathing and raise the temperature inside.
Well-chosen solar control systems are a worthwhile investment for years; they not only increase the comfort of the home, but also help to save energy by reducing the need for air conditioners.
