Custom Sizes Available:

Width: 400/600mm | Thickness: 12mm (Length customizable)  

4-Layer Structure:

1. Top Layer: Over 100 decorative film/wallpaper options—premium, dust-resistant, easy-to-clean, waterproof, and wear-resistant.  

2. Second Layer: 15mm thick PVC steel-reinforced impact-resistant panel, free from aluminum/iron thermal bridges, non-signal shielding, ultra-durable, with tongue-and-groove quick-installation for effortless assembly.  

3. Third Layer: 10.5mm refrigerator-grade polyurethane fireproof insulation board, thermal resistance 0.5 (equivalent to a 37cm brick wall).  

4. Base Layer: Aluminum-coated heat-reflective, anti-mold, and antibacterial layer. Paired with wooden studs, radiant thermal resistance reaches 0.6 (equal to an additional 50cm brick wall).  

Key Advantages:  

1. Thermal Insulation: Combined thermal resistance 1.1 (≈4.5cm foam or 37+50cm brick walls). Improves energy efficiency by 65–75% vs. original walls, reducing costs by over 50%.  

2. Energy & Cost Savings: Interior ceiling/wall insulation enables instant heating without pre-warming. Room-specific temperature control, compact yet continuous thermal enclosure—more efficient than external insulation, ideal for intermittently heated standalone buildings.  

3. Fast Installation & Noise Reduction: Quick, stylish installation with integrated insulation and decoration. Premium finishes achieved in one step.  

(Note: “400V/600V” denotes panel width (mm) to avoid confusion with voltage. “Tongue-and-groove” clarifies “公母口.” Metric units (cm/mm/°C) and EN-standard fire ratings ensure global readability. “Steel-reinforced” specifies PVC panel strength.)
