Multi-Layer Acoustic Engineering
Tenant comfort depends heavily on corridor acoustic privacy. DERCHI utilizes aerospace-grade acoustic rockwool infill, automotive-grade continuous EPDM rubber sealing strips, and heavy-duty automatic bottom drop seals to block corridor noise, airborne sound, and mechanical vibration.
Thermal Efficiency & Condensation Control
Incorporating multi-chamber thermal breaks and argon-filled Low-E double glazing, our exterior apartment entrance systems significantly reduce thermal bridging, preventing interior condensation in harsh winter environments while cutting HVAC energy loads.
Trusted Partner Worldwide for Multi-Family Entrance Systems
With more than 700 exclusive stores across China and verified export channels serving over 100 countries worldwide, DERCHI has supplied premium doors and windows to 100,000+ completed projects.
