What are the characteristics of SPD water-based foamed polyurea sound insulation board?

SPD water-based foamed polyurea sound insulation insulation board uses all-water foamed polyurea foam as the core material, combined with the composite fiberglass mortar cloth to strengthen the structure, forming a multi-functional building material with sound insulation, heat preservation, waterproof and weather resistance properties. Its characteristics can be summarized as follows:

1. Advantages of core materials

Fully water-expanded polyurea foam

Environmental protection: Using water as the foaming agent avoids environmental pollution caused by traditional chemical foaming agents and complies with green building standards.

Lightweight and high strength: Polyurea foam has low density but high compressive strength, which can effectively reduce building loads while maintaining structural stability.

Closed cell structure: The foam has a closed cell structure inside, with low thermal conductivity and excellent thermal insulation performance, which can effectively prevent heat transfer.

Composite fiberglass mortar cloth reinforcement

Structural stability: Fiberglass mortar cloth serves as a reinforcement layer to improve the tensile strength and impact resistance of the board and prevent cracking or deformation.

Durability: Fiberglass material is corrosion-resistant and aging-resistant, extending the service life of the board and reducing subsequent maintenance costs.

2. Performance characteristics

Efficient sound insulation

The porous structure of polyurea foam can absorb and disperse sound waves, reduce air sound transmission and structural sound transmission, and is suitable for scenes with high sound insulation requirements (such as residential floors, theaters, etc.).

The composite fiberglass mortar cloth further blocks the sound bridge and improves the overall sound insulation effect.

Excellent insulation

Low thermal conductivity and high thermal resistance can effectively reduce energy loss caused by indoor and outdoor temperature differences and improve building energy efficiency.

It is suitable for heating areas in the north or areas with high air conditioning demand in the south to reduce heating/cooling energy consumption.

Waterproof and moisture-proof

The polyurea material itself has excellent waterproof properties, and the surface is dense and seamless, which can prevent moisture penetration.

The fiberglass mortar cloth reinforcement layer further blocks moisture and avoids performance degradation caused by humidity changes.

Strong weather resistance

Polyurea foam is resistant to ultraviolet rays, acid and alkali, and chemical corrosion, and can adapt to different climate environments (such as high temperature, high humidity, salt spray, etc.).

Fiberglass mortar cloth enhances structural stability and prevents expansion or contraction caused by temperature changes.

3. Adaptability to application scenarios

Rough room and fine decoration floor heating

The boards can be laid directly on the floor to serve as the insulation layer of the floor heating system to improve heating efficiency.

The surface is flat to facilitate subsequent fine decoration construction (such as ceramic tiles, wooden floors, etc.).

Floor insulation and sound insulation system

Strictly meet the requirements of the new national standards, provide technical support for the construction of 'good houses' and improve living comfort.

It is suitable for buildings such as residences, schools, hospitals and other buildings that have strict requirements for sound insulation and thermal insulation.

Green Building and Energy Saving Renovation

The panels have excellent environmental performance and can help projects obtain green building labels such as LEED Gold and WELL Platinum certification.

It is suitable for energy-saving renovation of existing buildings and improves the energy efficiency level of buildings.

4. Technical Certification and Standards

Corporate standards and industry recognition

Zhejiang Keda New Building Materials Co., Ltd. has formulated the corporate standard 'Q/ZKD 019-2025 SPD Water-based Foamed Polyurea Sound Insulation and Insulation Board' to clarify technical requirements and quality indicators.

The product has passed testing by authoritative organizations, and its performance indicators are in line with or better than national standards.

Demonstration cases and certification

It has been used in many 'good house' construction demonstration projects and has obtained LEED Gold and WELL Platinum certifications.

It has become a typical case of digital architecture empowering high-quality development and promoting the technological upgrading of the industry.
