Full-featured solution for floor sound insulation and insulation projects

Highlights of the Sound Expo

The general manager of Tianjun County gave a keynote speech to unlock a new era of floor sound insulation and insulation!
The 8th China Acoustic Industry Development Conference (CAAF Acoustic Expo) in 2026 will be attended by big names and will be an unprecedented event. Mr. Tian Junxian, general manager and senior engineer of Zhejiang Keda New Building Materials Co., Ltd., was invited to the stage to deliver an authoritative report on the theme of 'Exploration of Full-Functional Solutions for Floor Sound Insulation and Insulation Engineering'.

The on-site venue was packed with industry colleagues, experts, scholars and engineering practitioners gathered together in an orderly and focused atmosphere. The general manager of Tianjun County delivered a speech full of enthusiasm and useful information. The audience listened attentively and recorded carefully, and received bursts of applause throughout the speech. It became a highly anticipated and important share of this conference.

Following the general trend of national standards and interpreting the new changes in the industry,
at the beginning of the report, General Manager Tian Jun County gave an in-depth analysis of the current policy changes in the field of building sound insulation:
With the successive implementation of GB55038-2025 'Residential Project Specifications' and JCT60036 'Technical Specifications for Building Sound Insulation', domestic building sound insulation has officially entered the era of fully closed-loop supervision of mandatory design, mandatory construction, and mandatory actual testing and collection.
Residential floor sound insulation has become a hard front-end indicator for delivery. The impact sound insulation requirements of high-standard projects have been significantly upgraded. Traditional sound insulation materials and old systems can no longer adapt to the new regulatory threshold. The industry is in urgent need of high-performance, systematic, and full-cycle innovative solutions. Upgrading of building sound insulation and insulation is a general trend and is urgent.

Directly addressing the pain points of the entire industry chain and accurately responding to the demands of multiple parties
. During the sharing process, General Manager Tian Jun County based on the perspective of the entire industry chain of design institutes, Party A, general contractors, and owners, accurately dissected the core demands of the industry:
• For the design end: the plan complies with standards, avoids design risks, has a simple and clear structure, has a high pass rate for drawing approval, the system is stable and durable, and eliminates later cracking and collapse, and owner complaints
• For costs and Party A: material grading and adaptation, precise cost control, localized stable supply, and guaranteed project delivery
• For general construction contractors: materials are easy to purchase, the structure is minimalist, construction is convenient, and the implementation efficiency is greatly

Hard-core technology breakthrough, SPD sound insulation and insulation product strength out of the circle
In response to common problems in the entire industry, the general manager of Tianjun County officially launched the core result of Zhejiang Keda's self-research—SPD water-based foamed polyurea sound insulation board.
The product is based on micron-sized small-pore water-based polyurea foam, which has an internal elastic flexible soft-segment molecular structure, and is perfectly compatible with sound insulation and thermal insulation properties:
✅ 60% barrier, 40% sound absorption, double noise reduction, full sound insulation efficiency
✅ Authoritative laboratory actual measurement: impact sound improvement can reach more than 18dB, and the actual measured data far exceeds the highest national standard
✅ The structure has strong stability, does not collapse, crack, or deform, and is durable and reliable throughout the entire life cycle
. It simplifies the construction process, greatly reduces the overall cost, and is suitable for all types of residential and public building ground projects.
From theoretical research and development to project field verification, real test data and implementation effects are used to confirm the hard-core breakthroughs and practical value of new technologies and new materials.
