2680 Building glass visible light transmission ratio is invalid?
Insulating glass is characterized by environmental protection with sound insulation and other advantages "dew point detection" is to test the airtight insulation to ensure that the air cavity is independent and stable drying "visible light transmission ratio" is for different design requirements need to use different insulating glass products Conducting different substrate transmittance is not the same as "shading coefficient" is for coated glass or.
