| Panel Weight |
Approx. 80kg/㎡, extremely heavy dead load |
Approx. 16kg/㎡, only 1/5 of solid marble |
No main steel structure reinforcement required, reducing keel costs by 18%-22% and adapting to load limits of high-rise commercial buildings |
| Water Absorption (Key Anti-Efflorescence Index) |
1.2%–2.0% with strong water and salt permeability |
≤0.13%, over 90% lower than solid stone |
The fully sealed composite structure blocks water and salt penetration, fundamentally eliminating the root cause of stone efflorescence |
| Coastal Aging & Efflorescence Performance |
Obvious whitening, efflorescence and yellowing appear within 12–18 months; over 75% of facade deterioration rate within 3 years |
No efflorescence, yellowing or delamination after 1500-hour salt spray test and 2000-hour high-humidity aging test |
Nearly zero facade deterioration rate for long-term coastal outdoor use, minimizing frequent renovation and maintenance work |
| Typhoon & Wind Resistance |
Concentrated force bearing; prone to slab fracture and anchor loosening under strong negative wind pressure |
Withstands high wind pressure up to 5.5kPa; evenly disperses wind force across the entire panel surface |
Fully adapts to Guam’s typhoon-prone climate with no risk of panel damage or falling off |
| Seismic Resistance & Safety |
High inertial load under vibration; brittle and easy to crack or fall off entirely during earthquakes |
Low lightweight load; honeycomb structure absorbs vibration energy with excellent overall stability |
Complies with curtain wall codes for high-seismic zones, completely eliminating stone falling safety hazards |
| Construction Cycle |
Complicated procedures requiring steel keel reinforcement, leading to long construction periods |
Prefabricated large-format panels for fast dry-hanging; construction efficiency improved by over 40% |
Greatly shortens project delivery time and adapts to overseas construction site requirements |
| Long-term Maintenance Cost |
High maintenance cost; frequent repairs and renovation required every 2–3 years due to common surface defects |
Ultra-low maintenance cost with stable weather resistance and long-term durability |
Sustains premium facade appearance for luxury stores and reduces long-term operational costs |
| Heat Conduction & Thermal Insulation Performance |
Thermal conductivity: 1.3–3.5W/(m·K); fast heat transfer and strong heat storage. Exterior walls continuously accumulate heat under strong sunlight, causing indoor temperature rise and increasing long-term air conditioning energy consumption |
Thermal conductivity: only 0.10–0.13W/(m·K), improving thermal insulation efficiency by over 90%. The sealed honeycomb air layer effectively blocks heat transfer and avoids heat accumulation |
Adapts to year-round high-temperature and strong sunlight climate in Guam, realizes constant-temperature thermal insulation, reduces building energy consumption, and meets energy-saving design standards for high-end commercial buildings |
