Windows are not only used to see the scenery outside, but also determine the quality of life to a great extent, but sometimes, many problems are not noticed at all.
Home is a habitat, a relatively independent small environment created by itself, protecting itself from wind and rain, sun and sound, and protecting itself from any external factors.
Relatively independent because it is impossible to live alone completely out of the external environment, and there needs to be a reasonable communication and exchange indoors and outdoors. In this small environment, it is necessary to have suitable temperature, humidity, air and light, as well as suitable sound environment.
You need a window to transmit light, so extra heat will come with the sun.
You need ventilation in the windows, so dust and mosquitoes may come with the circulating air.
Problems often come with your needs, so don't be careless about your window.
