• The VI AB® CDM polyurethane rubber series soundproof pads are a sustainable type of vibration isolation pad. They can be used in both wet and dry acoustic floating floor constructions. Made from polyurethane and bonded to high-density non-woven fabric using polyurethane elastomer, they come in different densities suitable for various loads, resulting in different hardness characteristics. CDM is particularly well-known for its noteworthy stiffness ratio, such as low dynamic/static stiffness. This stiffness ratio makes it an ideal vibration and soundproof material, effectively absorbing vibrations and noise across all frequencies. It can improve impact sound insulation by 16–35 dB, allowing the impact sound insulation performance of building partition floors to exceed current green building standards and meet or surpass the requirements of five-star hotels.

• The VI AB®CDM polyurethane rubber series soundproof mats, due to their thin material thickness and excellent flexibility and adhesion, can closely fit the surface of concrete floors. Tiles or stone can be directly adhered on top using 35mm dry-mix mortar or 10mm special adhesive, with almost no impact on indoor ceiling height or construction process.
  
• The VI AB®CDM polyurethane rubber series sound insulation pads have a high coefficient of friction on the surface, making them difficult to shift after installation, which helps with wind resistance and finished product protection. With a thin thickness and high stiffness, they can significantly improve the foot-feel of various common low-density foam soundproof pad products, completely eliminating quality risks such as hollowing and cracking. At the same time, since the material's surface is laminated with a layer of tough geotextile, it helps reduce the product's lateral shrinkage. When combined with the surface mortar, it will not cause hollowing or cracking due to shrinkage, as seen with traditional foam soundproof pads, effectively preventing damage from foot traffic or wheel compaction. Its network-patterned surface can also enhance adhesion with the mortar layer.
  

• The breakthrough sound insulation effect and excellent construction performance of VI AB®CDM polyurethane rubber series acoustic insulation mats completely eliminate the concerns of developers and designers about potential quality problems in floor slab sound insulation systems, promote the widespread application of floating floor sound insulation, and thus improve the quality of indoor acoustic environment in domestic residential buildings.
