Sun-protection film on windows to reduce the temperature in the apartment and house

I remember in my childhood in the village, in the summer heat, we covered the windows with thick bedspreads so that the sun's rays would not heat the rooms. Helped to lower the temperature in the house, if it was done in the morning from the moment of sunrise.

About 15 years ago, I figured out the idea of ​​\ u200b \ u200bthe production of sun blinds from a film with a metal coating (from a package for flowers). But due to limited and seasonal demand, the idea was not implemented.

In some places such sun-protection curtains can now be found on sale. And you can make sun protection yourself. This requires a special film. In most large cities, there is a wide choice:

It is cut to the size of the glass in the window, the glass is wetted with water and the film is smoothed out, squeezing out water and air. The sticking effect occurs. For reliability, the edges are fixed with tape. And you can simply fix it on double-sided tape. But the kind of tinting with such fixation will be worse.

Outside view, almost mirrored surface. And you might think that the film will reflect 100% of the light and it will be dark inside, you will have to turn on the lighting. But no. The film transmits light:

At one time, I pasted my trial product on the window. Light penetrates the film, there will be enough lighting inside. The advantage of such sun protection is that it can be removed and in winter it will not interfere with the heating of the premises. And in a private house it can be like saving on heating.

Sometimes I see balconies with such a coating glued to the glass. Reduces the effect of the greenhouse on the sunny side of the house.

The effect of these sun shades will diminish when the walls of the stone house get hot during the weekly heat. This is the case in panel apartment buildings.

Probably, this method will be useful in the southern regions, where there are many sunny days and the solar radiation itself is more powerful.
