Features:
1. Enhanced Mechanical Strength: Tempered processing ensures surface hardness ≥7H (Mohs scale) and excellent impact resistance, preventing breakage from outdoor impacts (e.g., hail, debris).
2. Superior Light Transmittance: ≥90% (low-iron type ≥93%) visible light transmittance maximizes solar energy absorption, boosting the heating efficiency of solar water heater systems.
3. Safety Compliance: Fully tempered structure breaks into small, blunt-edged fragments (no sharp shards), meeting international safety glass standards (ASTM C1048/EN 12150) for safe installation.
4. Exceptional Weather Resistance: Advanced coating and premium glass material resist UV radiation, extreme temperatures (-30℃ to +350℃), humidity, and salt spray, maintaining performance for ≥10-15 years outdoors.
5. Optional High-Performance Coatings: AR coating reduces reflectivity ≤4% for better light absorption; Low-E coating cuts heat loss (emissivity ≤0.12) to improve energy efficiency.
6. Customizable Specifications: Flexible thickness (3-8mm), sizes (standard/custom), and edge processing (seamed/ground) to fit flat-plate, vacuum tube, and other solar heater collector models.
7. Eco-Friendly & Standard-Compliant: RoHS/REACH certified, made of non-toxic materials; complies with ISO 9050 for solar optical properties, suitable for global residential/commercial/industrial applications.
Application:
1. Solar Swimming Pool Heating: Used as cover glass for solar pool heaters. It captures solar energy to heat pool water, extending the swimming season while lowering the energy consumption of electric or gas pool heaters.
3. Solar-Assisted Heating Systems: Combined with building heating systems in cold regions. It absorbs solar energy to preheat circulating water, reducing the load of central heating systems and improving energy efficiency for residential communities and commercial buildings.
4. Off-Grid & Remote Area Applications: Ideal for areas without stable electricity supply (e.g., mountainous regions, rural villages, island communities). It powers standalone solar water heater systems to solve basic hot water problems, with its weather-resistant feature adapting to harsh outdoor environments.
