I don't know if you are checking the glass or something. Now some glasses have a green film, which can block more than 50% of solar energy. When the outdoor temperature is 38-39, it is 3.5 degrees lower than that of ordinary glass, saving more than 30% of air conditioning power consumption. It is a high-tech and energy-saving safety material.

Green film belt is said to have the following benefits:

1, high heat insulation and energy saving (heat insulation rate is as high as 95%), saving 30% of air conditioning electricity, making the room warm in winter and cool in summer.

2, the ultraviolet blocking rate is not less than 99%, protecting indoor furniture, carpets and other items from fading and aging; No light pollution, so that people can avoid skin cancer, glaucoma, cataracts and other diseases.

3. Good light transmittance, ensuring sufficient indoor natural illumination brightness.

4. The strength of the glass is improved by 3-20 times after installation and pasting, which is safe and explosion-proof, damaged by earthquake and typhoon, and stuck by the film when the glass is broken, and will not splash and hurt people.

5, one-way perspective, it is clear from the outside, but there is no way to peek at the indoor life outside, protecting the privacy of the home.

6, easy to clean, no special maintenance, long service life. 10- 15 years will not fall off.
