|---|---|---|---|---|---|
| VLT | 85% | 73% | 38% | 34% | 17% |
| IRR 950nm | 56% | 95% | 91% | 93% | 89% |
| IRR 1400nm | 64% | 98% | 95% | 97% | 93% |
| UVR | 99% | 99% | 99% | 99% | 99% |
| TSER | 38% | 55% | 76% | 86% | 74% |
| Total Solar Transmittance | 0.62 | 0.45 | 0.24 | 0.14 | 0.26 |
| Internal Reflectance | 08% | 08% | 08% | 08% | 08% |
| Shading Coefficient | 0.70 | 0.51 | 0.27 | 0.16 | 0.29 |
| Haze | 0.20 | 0.58 | 0.20 | 0.62 | 0.65 |
| Scratch Resistance | 3H | 3H | 3H | 3H | 3H |
| Thickness | 4mil | 4mil | 4mil | 4mil | 4mil |
| Color Decay Time | 10 years | 10 years | 10 years | 10 years | 10 years |
All specifications share a thickness of 4mil, UVR of 99%, and scratch resistance of 3H. The listed color decay time is 10 years across the series. The main variations are in VLT, IRR, TSER, and haze.
Model Configuration and Performance Characteristics
The different specifications offer varying combinations of visible light transmission and solar performance:
- ACF85-4: With 85% VLT, it provides the highest visible light transmission in the series.
- ACF75-4: Features 73% VLT and 98% IRR at 1400nm, combining high light transmission with strong infrared rejection at the specified wavelength.
- ACF40-4: Provides 38% VLT and 76% TSER, offering a balance of light transmission and total solar energy rejection.
- ACF35-4: Achieves the highest TSER in the series at 86%, with a VLT of 34%.
- ACF18-4: Has the lowest VLT at 17%, providing the darkest appearance among the available specifications.
When comparing these options, buyers should consider VLT, IRR at the specified wavelengths, TSER, and haze together. These parameters represent different aspects of optical and solar performance. A lower VLT does not necessarily indicate a higher TSER, as demonstrated by the comparison between ACF35-4 and ACF18-4. Local automotive window tint regulations should also be taken into account.
