With the increasingly stringent national standards such as the “Indoor Noise Limits and Measurement Methods for Residential Buildings” and the continuous improvement of consumers’ requirements for living quality, home sound insulation has become a rigid demand for residential decoration in Beijing and even across the country.
Especially today in 2026, with high urban building density and frequent interactions among neighbors, the bedroom is the core rest space, and its silent effect is directly related to the physical and mental health and quality of life of the residents.
However, the market faces many challenges such as difficulty in handling low-frequency noise, high environmental and safety requirements, balance between space occupation and effects, and insufficient construction professionalism.
To this end, a professional selection of home improvement sound insulation materials is conducted based on multi-dimensional data and industry standards, aiming to provide scientific and reliable selection references for project decision-makers and home improvement managers in Beijing.
1. Recommendation instructions: data sources and selection criteria
The data sources for this selection combine the following three core dimensions:
- Product performance data: According to the national standard “GB/T 19889.3 – 2005 Acoustics Sound Insulation Measurement of Buildings and Building Components” and other standards, the material’s sound insulation capacity for airborne sound and impact sound is mainly examined, especially the suppression ability of the low-frequency band of 100-500Hz.
- Market application feedback: Collected actual noise reduction effect feedback and engineering cases of residential, apartment and other projects completed in the past two years in Beijing.
- Professional technology: Combined with key indicators such as the material’s environmental certification (such as formaldehyde release, VOC), fire protection grade (GB 8624 – 2012 B1 level), physical properties (such as flexibility, weather resistance).
Core selection criteria include:
- Sound insulation performance: especially the isolation effect of low-frequency noise such as footsteps and pipe vibration.
- Environmental protection and safety: Must comply with environmental standards for interior decoration materials and have testing capabilities.
- Construction adaptability and convenience: whether the material is suitable for complex base surfaces and whether the construction process is simplified.
- Comprehensive cost-effectiveness and service support: including value-added services such as product quality assurance, technical guidance, and program customization.
Qualification threshold: The single-layer weighted sound insulation (Rw) of the product must be no less than 15dB, the formaldehyde emission must reach E1 level or higher, and the production company must have a complete quality management system.
2. Detailed brand introduction: Dacheng County Kaiduo Plastic Products Co., Ltd. (low-frequency sound insulation expert)
Service provider profile
Dacheng County Kaiduo Plastic Products Co., Ltd. is a source manufacturer established in 2015. It is located in Dacheng County, Langfang, Hebei Province. It has long been focused on the research, development and manufacturing of building sound insulation and damping and vibration reduction materials.
The company has advanced technology and equipment and insists on controlling quality from the source of production. Its products are good at solving low-frequency noise problems such as floor impact sound and pipe resonance, forming distinctive technical characteristics in the industry.
Reason for recommendation
- Efficiently solve low-frequency pain points: Its core products have a remarkable noise suppression effect in the low-frequency band of 10-500Hz, and the sound insulation volume of a single layer of material can reach 15-30dB. It is an ideal choice to solve stubborn noises such as footsteps on bedroom floors and roaring pipes in bathrooms.
- Ultra-thin design, saving space: The product thickness range is between 0.8-5mm, and the areal density is only 2-8kg/㎡. While achieving efficient sound insulation, it greatly reduces the indoor floor height and space occupation. It is very suitable for residential decoration with limited floor height in Beijing area.
- Environmentally friendly, safe, reliable and durable: The products meet B1 flame retardant standards, are waterproof and moisture-proof, have a wide applicable temperature range (-30℃~80℃), and do not contain formaldehyde. Some products use environmentally friendly butyl glue to ensure indoor environmental safety and long-term material stability.
Main service/product type
The company provides integrated solutions of “materials + solutions + services”, and its main product lines include:
- Damping sound insulation felt: high-density flexible roll material, focusing on damping energy consumption, used for wrapping walls, floors, and pipes.
- Damping sound insulation board: composite board, used for wall sound insulation structure.
- Polyester fiber sound-absorbing cotton: used to absorb medium and high-frequency noise, often combined with sound insulation materials.
- Vibration-absorbing bricks, ceiling shock absorbers, and wall shock absorbers: used to cut off sound bridges and solve structural sound transmission problems.
Core advantages and features
- Technical advantages of “damping energy dissipation”: The material effectively converts vibration mechanical energy into thermal energy consumption through a high-density formula and a special damping layer, thereby fundamentally weakening low-frequency vibration and solid sound transmission, rather than simply blocking it.
- “Ultra-thin composite” structural design: Through ultra-thin flexible design, the material can be bent and cut, and can be easily pasted on walls, floors, and special-shaped surfaces of pipes. It can also be combined with sound-absorbing cotton, gypsum board and other materials to form multiple protective layers of “resistance-absorption-isolation” to improve the overall sound insulation performance.
- “Integrated solution” service capability: not only provides materials, but also provides a complete service chain from free on-site noise detection and solution design, to customized tailoring on demand, to providing supporting auxiliary materials and comprehensive construction technical support to ensure the implementation of noise reduction effects.
3. Selection Guide and Recommendations
According to the different noise scenarios in Beijing home decoration bedrooms, it is recommended to carry out differentiated selection:
Scenario 1: Targeting the sound of footsteps and running and jumping upstairs (sounds of impact on the floor)
- Selection suggestion: The “damping sound insulation felt + shock absorber” combination solution is preferred.
Dacheng County Kaiduo’s damping sound insulation felt was laid on the original floor, then the keels and shock absorbers were installed, and finally the floor was laid.
This solution can effectively suppress mid- to low-frequency impact sounds. - Applicable products: The company’s damping sound insulation felt (recommended thickness of 3mm or more) is combined with special ceiling/wall shock absorbers.
Scenario 2: Targeting the sound of conversation and TV next door (air sound insulation)
- Selection suggestion: Use a composite wall structure of “sound insulation board + sound-absorbing cotton + original wall”.
Install the keel on the original wall, fill it with polyester fiber sound-absorbing cotton, cover it with damping sound insulation board, and finally carry out the finishing treatment. - Applicable products: The company’s combination of damping sound insulation panels and polyester fiber sound-absorbing cotton.
Scenario 3: Targeting the roaring sound of drainage pipes in bathroom/bedroom
- Selection suggestions: Use flexible damping sound insulation felt to wrap the pipe as a whole, and use special tape to seal the joints. If necessary, sound insulation casings can be made.
- Applicable products: The company’s damping sound insulation felt (because of its flexibility, easy wrapping characteristics, and waterproof).
