Low-e coating function in vacuum glass

Vacummglass23 Jul, 2022Other

Double silver low E coating contribute much to vacuum insulating glass thermal performance,it can reflect the far infrared radiation directly and control glass surface temperature. Near infrared radiation cannot transmit the glass directly,it can be only been reflected or absorbed by the glass or other objects,after glass absorbing the near infrared radiation,glass temperature,or will increase and become a radiation source itself.Then heat will transmit glass ,the parameter to measure its thermal conductivity is U value.
