Corridor noise is one of the main causes of guest complaints. How do you ensure acoustic performance

We do not simply provide a thicker door leaf; we provide Acoustic System Integration. Our solution includes 45mm–48mm high-density graphene or semi-solid wood core filling, triple sealing strips, and most importantly, an Automatic Drop Seal. We can align the acoustic performance according to different room types, with customized STC ratings from 35dB to 45dB.
