Multi-Layer Structure & Core Advantages

Engineered with a high-density XPS core and dual-side fiberglass mesh mortar for 100% waterproof performance and ultimate bond strength.

Top Layer: 0.035 mm - 0.1 mm Embossed Aluminum Foil

High-reflectivity embossed aluminum foil spreads heat evenly across the entire floor surface, eliminating cold spots and accelerating warm-up time.

Core Layer: High-Density Closed-Cell XPS Board

100% closed-cell extruded polystyrene insulation prevents downward thermal loss, providing exceptional structural rigidity under heavy floor loads.

Bottom Layer: Pre-formed Pipe Channels

Factory-cut precision grooves securely lock heating pipes (PEX/AL-PEX) into position without requiring additional fixing clips.

Rapid Thermal Response

Enables quick heating response times within 20 minutes compared to traditional wet screed systems, saving up to 30% energy consumption.

Dust-Free Dry Installation

No wet concrete screed required. Panels can be laid directly onto subfloors, allowing laminate, engineered wood, or tiles to be installed immediately.

Ultra-Thin & Space Saving

Available in low-profile thicknesses (25mm / 30mm), making it ideal for low-threshold retrofit projects and modern high-rise apartments.

High Compressive Strength (≥ 300 kPa)

High-density core withstands heavy residential and commercial furniture loads without deformation over long-term usage.
