Self-adhesive wall sound insulation board is a new type of material specially developed for wall sound insulation. Thanks to its unique self-adhesive structure and outstanding performance, it has become a popular option in modern decoration.

1. Ready-to-stick for easy installation

The self-adhesive sound insulation board is pre-coated with high-performance pressure-sensitive adhesive, eliminating the need for additional adhesive mixing. During construction, simply peel off the release liner and attach the board directly to a flat wall; the entire installation can be completed by one person. Compared with traditional sound insulation cotton that requires keel fixing and sound insulation felt that demands full glue coating, its construction efficiency is boosted by over 60%, making it ideal for old house renovations and fast-track decoration projects.

2. High-density structure for superior sound insulation

It features a multi-layer composite structure with a 5–8 mm high-density rubber and plastic foam core layer boasting a density of 800–1200 kg/m³. Professional tests show its Sound Transmission Class (STC) rating reaches 35–40 dB, which effectively blocks medium and low-frequency noises such as voices and footsteps. Combined with a microporous sound-absorbing surface coating that absorbs more than 85% of high-frequency noise, it forms a dual noise reduction system integrating sound barrier and sound absorption.

3. Ultra-thin and lightweight with zero space occupation

The board is merely 5–10 mm thick and weighs around 2–3 kg per square meter, far lighter than traditional brick walls at approximately 120 kg per square meter. Installation barely reduces the net indoor space, making it perfect for small apartments and spaces with limited floor height. Available in a standard 900×600 mm size, it can be freely cut and spliced to fit irregular wall surfaces of all kinds.

4. Eco-friendly and safe, suitable for families with infants and pregnant women

Made of eco-friendly rubber and plastic substrates, the product complies with the EU RoHS Directive. Its formaldehyde emission is ≤0.05 mg/m³ and total volatile organic compound (TVOC) emission ≤0.3 mg/m³. The surface coating adopts a water-based acrylic system with no pungent odour, allowing immediate occupancy after installation. Tested by the National Center for Quality Supervision and Inspection of Fireproof Building Materials, it achieves Class B1 fire resistance, self-extinguishing without molten drips once away from open flames.

5. Moisture-proof and mildew-resistant for long service life

The material itself delivers excellent weather resistance with stable performance under temperatures ranging from -40°C to 80°C. Its nano waterproof surface coating delivers a water absorption rate below 0.1%, enabling direct application in damp areas such as bathrooms and kitchens. After a 500-hour damp-heat resistance test, the boards show no deformation or mildew, with a service life of over 10 years.

6. Integrated decorative design for cost savings

Multiple surface finishes including wood grain, stone grain and solid colours are optional, removing the need for extra wall decoration. Seamless splicing technology paired with special edge trims enhances overall aesthetics by 40%. In contrast to traditional separate construction of a sound insulation layer plus a decorative layer, it cuts total comprehensive costs by more than 25%.

These six core advantages make self-adhesive wall sound insulation boards an ideal choice balancing functionality and aesthetics. Whether for home theatre renovations, office soundproofing or hotel room upgrades, this material delivers efficient and convenient solutions to create quiet, comfortable living and working environments for users.
