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.)

Available Sizes:
Length: 2400/2800/3000mm | Width: 1200mm | Thickness: 18mm
4-Layer Structure:
1. Top Layer: Diverse PVC/PET decorative films with high-end finishes—dust-resistant, easy to clean, waterproof, and wear-resistant.
2. Second Layer:4mm magnesite fireproof impact-resistant panel, withstands 1400°C高温 (*or "withstands extreme heat up to 1400°C"*), free from aluminum/iron thermal
bridges, non-signal shielding, ultra-durable, and designed for modular, tool-free installation.
3. Third Layer: 14mm refrigerator-grade polyurethane fireproof insulation board, thermal resistance 0.7 (equivalent to a 50cm brick wall).
4. Base Layer: Aluminum-coated heat-reflective, anti-mold, and antibacterial layer. Combined with wooden studs, radiant thermal resistance reaches 0.6 (equal to an
additional 50cm brick wall).
Installation:
Uses I-shaped decorative trim for one-step fixing and finishing.

Key Advantages:
1. Thermal Insulation: Combined thermal resistance 1.3 (≈6cm foam or 37+50cm brick walls). Cuts energy use by 65–75% vs. original walls, slashing costs over 50%.
2. Noise Reduction: Polyurethane’s porous structure delivers 29dB soundproofing for quieter interiors.
3. Eco-Safe: Brand-certified materials, zero formaldehyde, ensuring healthy living.
4. Fire Safety: Class-A fireproof panel (4-hour耐火极限 or "4-hour fire resistance rating"), paired with B1-grade self-extinguishing materials (or "flame-retardant
materials"), eliminating fire risks.
5. Moisture & Stain Resistance: Waterproof, mold-proof, non-degrading, and easy to clean.
6. Dry Installation: Modular assembly, no wet works, fast and hassle-free.
(Note: "Magnesite" is retained for material accuracy. "1400°C" uses global metric standards. "Class-A/B1" follows EN fire ratings; add "equivalent to [local
standard]" if needed. "50cm brick wall" clarifies analogy. "Modular, tool-free installation" emphasizes user-friendly design.)
