Top Layer: Polymer Cement Mortar & Fiber Mesh

Provides superb tile adhesive bonding strength and prevents surface cracking under heavy loads.

Core Layer: High-Density Closed-Cell XPS

100% waterproof and vapor-impermeable core providing thermal insulation and moisture resistance.

Bottom Layer: Reinforced Polymer Mortar

Ensures high flexural strength and solid anchoring to subfloors or wall framing.

Ultra-Lightweight & Easy Handling

80% lighter than traditional cement backer boards, dramatically reducing shipping costs and job-site fatigue.

100% Waterproof & Mold Proof

Zero water absorption protects underfloor heating and wall structures from moisture degradation.

Fast & Clean Installation

Can be cut easily with a standard utility knife without creating hazardous dust or requiring power tools.

High Compressive Strength (≥ 300 kPa)

Withstands heavy tile and stone loads, making it ideal for commercial floors, wet rooms, and spa areas.
