Electromagnetic shielding glass realizes bidirectional electromagnetic signal isolation by reflecting, absorbing and attenuating electromagnetic waves, while retaining glass's inherent light transmission and visibility. It is compatible with tempering, laminating, fire-resistant and ballistic-resistant processes, and is mainly applied in four key scenarios: classified spaces, precision instrument environments, electromagnetic radiation protection areas and anti-interference spaces, where the required shielding effectiveness (SE value, dB) varies by scenario.
