3.2mm 4mm Solar Tempered Glass for Solar Water Heater Collector with High Light Transmittance
Product introduction
3.2mm/4mm Solar Tempered Glass for Solar Water Heater Collectors (High Light Transmittance) is a scenario-specific safety glass tailored for the cover of solar water heater collectors (flat-plate/vacuum tube), optimized for 3.2mm and 4mm thicknesses to balance light transmission, strength, and thermal performance.

| Diagonal difference | ≤0.1-0.2% |
| Overall bow/warp | <0.2% |
| Local warp | ≤0.3mm/300mm |
| Fragmentation test | ≥40 particles within 50x50mm |
| Scratch hardness | 4~5 |
| poisson's ratio | 0.2 |
| Tensile strength | 42n/mm2 |
| Pressure resistance | 700-900m/mm² |
| Standard size | 1220X2440mm 1500X2000mm, 1830X2440mm (customer size available) |
| Edge processiong | seamed/ground edges(deburred,no sharp corners) |
| Tempering grade | Fully Tempered |
Feature
1.Weather Durability: Resists UV radiation, extreme temperatures (-40℃ to 300℃), humidity, and corrosion, ensuring 10+ years of service life without yellowing or performance degradation.
2.Heat Loss Reduction: The tempered glass cover minimizes convective/radiative heat loss from the collector, enhancing the solar water heater’s overall thermal efficiency.
3. Optimal Thickness Design: 3.2mm (lighter, cost-effective for small/mid-size collectors) and 4mm (higher load-bearing, more durable for harsh outdoor conditions) meet different collector structure requirements.
4.Super High Light Transmittance: Typically ≥91% (for clear tempered glass) or ≥88% (for low-iron options), maximizing sunlight penetration to boost the collector’s heat-gathering efficiency (critical for solar water heating).
5.Tempered Safety Performance: 3-5 times stronger than ordinary glass; breaks into blunt, small fragments to avoid injury—essential for outdoor installation exposed to wind, hail, or falling debris.
Application
The 3.2mm/4mm High-Light-Transmittance Solar Tempered Glass is exclusively designed for solar water heater collectors (the core component of solar water heating systems), with applications focusing on matching different collector types, installation scenarios, and usage demands.
