A window’s sound and thermal insulation performance depends 70% on sealing and glass. Jinheng employs a “triple-layer sealing system”: the exterior uses superior weather-resistant EPDM rubber sealing strips, the middle features durable foam sealing strips, while the interior utilizes food-grade silicone seals, creating a stepped pressure barrier. For glass processing, Jinheng partners with leading glass processing enterprises, employing automatic molecular sieve filling, argon gas injection, and dual-seal technology with butyl rubber and silicone sealant for insulated glass production. The optional Low-E coating can reflect over 90% of infrared rays, enabling the entire window to achieve a U-value as low as 1.0 W/(m²·K), meeting Passivhaus standards.
