Bakit mas mataas ang price ng V-KOOL vs Other Tints?

Opinyon ko lang ito, dahil mataas ang IRR at TSER data nya. (Bukod sa mga technology na ginamit sa kanya at warranty length)

Compare natin some samples:

V-Kool VK40
Visible Light Transmission (VLT) - 43.0%
Infra-red Rejection (IRR) - 98.0%
Total Solar Energy Rejection (TSER) - 65.0%

Huper Optik C40
Visible Light Transmission (VLT) - 42.0%
Infra-red Rejection (IRR) - 88.0%
Total Solar Energy Rejection (TSER) - 55.0%

Solar Gard HP Charcoal 43
Visible Light Transmission (VLT) - 43.0%
Infra-red Rejection (IRR) - No data
Total Solar Energy Rejection (TSER) - 50.0%

3M Crystalline CR40
Visible Light Transmission (VLT) - 39.0%
Infra-red Rejection (IRR) - No data
Total Solar Energy Rejection (TSER) - 60.0%

3M Black Chrome BC40
Visible Light Transmission (VLT) - 42.0%
Infra-red Rejection (IRR) - No data
Total Solar Energy Rejection (TSER) - 47.0%

Meron ding budget tint ang V-KOOL. These are the SIGNATURE series at OEM series. Pero syempre mababa na ang IRR at TSER data ng mga ito.

another comparison set:

V-Kool VK70
Visible Light Transmission (VLT) - 70.0%
Infra-red Rejection (IRR) - 94.0%
Total Solar Energy Rejection (TSER) - 55.0%

Huper Optik C70
Visible Light Transmission (VLT) - 71.0%
Infra-red Rejection (IRR) - 91.0%
Total Solar Energy Rejection (TSER) - 47.0%

Solar Gard LX70
Visible Light Transmission (VLT) - 72.0%
Infra-red Rejection (IRR) - No data
Total Solar Energy Rejection (TSER) - 55.0%

Solar Gard Sterling 70
Visible Light Transmission (VLT) - 74.0%
Infra-red Rejection (IRR) - No data
Total Solar Energy Rejection (TSER) - 33.0%

3M Crystalline CR70
Visible Light Transmission (VLT) - 69.0%
Infra-red Rejection (IRR) - No data
Total Solar Energy Rejection (TSER) - 50.0%

3M FXST 70
Visible Light Transmission (VLT) - 70.0%
Infra-red Rejection (IRR) - No data
Total Solar Energy Rejection (TSER) - 28.0%

Malinaw sa spec kung bakit mas mura ang 3M FX. Maliwanag nga siya * 70% VLT pero mababa naman ang TSER data nya.

Pinakamahirap i-manufacture ang tint na maliwanag pero mataas ang heat rejection.
