Project Case Study: Soundproof Window Installation at Renaissance Shenzhen Luohu Hotel

On September 25, 2017, our company successfully completed the installation of soundproof windows in guest rooms at the Renaissance Shenzhen Luohu Hotel. Located in Luohu District, this premium five‑star hotel is part of the Renaissance brand under Marriott International and is widely known for its “Charity Hotel” identity and its iconic 50‑story revolving restaurant. As a luxury property, it demands the highest standards of guest comfort and acoustic quality.

The Challenge
Given its prime downtown location, the hotel faced significant external noise intrusion from the surrounding urban environment, which affected the tranquility of certain rooms and detracted from the overall guest experience.

Our Solution
To address this, we developed a custom‑engineered, high‑performance soundproof window solution tailored to the hotel’s specific site conditions. Our professional construction team executed the installation with meticulous precision, ensuring minimal disruption and maximum effectiveness.

Results
Post‑installation on‑site testing confirmed that indoor noise levels in the guest rooms were consistently stabilized at 35 decibels — a dramatic reduction that effectively blocks outside noise and creates a noticeably quieter, more restful space for hotel guests.

Client Feedback
The hotel management gave high praise for both the acoustic performance of our windows and the professionalism of our construction services.

Our Commitment
The successful completion of this project further validates our technical expertise and deep engineering experience in high‑end hospitality acoustic solutions. We remain dedicated to advancing soundproof window technology and providing efficient, tailored noise‑control solutions for hotels, residences, offices, and beyond.
