Product Introduction

This product is manufactured using pure foamed polyurethane, featuring a high-density microcellular structure that provides excellent elasticity, damping, and vibration isolation properties. It maintains its resilience under long-term compression and is resistant to collapse.

1. Nonwoven Fabric Lamination – Prevents Delamination and Cracking

The upper surface is laminated with high-density nonwoven fabric, ensuring stronger bonding with cement mortar. This significantly reduces the risk of delamination, debonding, hollow spots, and cracking caused by shrinkage.

Available Options: Without nonwoven fabric / Single-sided nonwoven fabric / Double-sided nonwoven fabric

2. Excellent Impact Sound Reduction – Firm Underfoot, Without Excessive Softness

Designed with low dynamic stiffness and high impact energy dissipation efficiency, this product effectively reduces noise transmitted through the floor structure, including footsteps and falling objects from upper floors. It is suitable for applications ranging from residential buildings to high-standard hotels.

Despite its slim profile, the material provides reliable support and resilience, delivering a firm and stable underfoot feel after installation. It minimizes the risk of excessive compression and floor settlement, achieving an effective balance between sound insulation and walking comfort.

Customizable Density & Fire Rating: Product density can be customized according to project requirements. The standard fire rating is Class B2, with an optional flame-retardant formulation available to achieve Class B1.
