Everyone says to buy a house to sit north and face south, and I have a friend who does the opposite. He deliberately bought a Xishai apartment, and others laughed at his head being squeezed by the door. He felt that the winter in Hefei was too cold, and most of the community did not have heating, and in the winter the sun was more precious than gold.
But just thinking about the sun in winter, the sun is also poisonous in summer! Xi Sun's room is almost fatal in the summer, 38 degrees outside the house, 40 degrees inside the house! How to decorate the windows of the western sun can become a problem. Friends are really rudderless, specially found an experienced teacher, to see what can be done to make this west sunning window not so hot in the summer.
The master said that the most basic method is to make the window of the western sun smaller. The wall is relatively thick, the heat insulation performance is stronger than the window, and the west-sun window can be reduced to effectively reduce the sunlight that shines into the room and make the room cool down. Friends are still counting on sunbathing in winter, where are you willing to change small windows?
There is also a simple way, that is, to buy a curtain with good shading and heat insulation performance to hang, the curtain can be opened and closed at will, flexible and convenient to use, is the choice of most people. But friends also feel that once the thick curtains are closed, the home will become a black hole hole, the light is not good, and it is depressed, and it will be dark in advance in the afternoon.
The master was really patient and gave another trick to his friend. Putting greenery on the windowsill is a good idea. Green plants have the effect of heat insulation, and a row of green plants on the windowsill can also block the sun and add shade to the interior. Green plants can also absorb dust in the air, clean air, really kill two birds with one stone. Friends provoked again, this green plant is so small that it does not cover much light, it is not practical. I couldn't listen to it anymore, but the master was not angry at all, and introduced another method.
The master said that in order to meet the needs of indoor shading in the summer, there is now an insulation film on the market, which can be attached to the window glass for heat insulation. The surface of this insulating film is a polyurethane film, and a highly reflective metal or metal oxide coating is added to the middle, which can ensure the inflow of light while insulating heat. This heat insulation film can not only isolate heat so that the indoor temperature is 3-6 degrees lower than outdoors, but also isolate 90% of ultraviolet rays. After listening to the teacher's words, my friend went to buy an insulation film the next day.
