It's amazing given all the affordable tech available these days, how few people are curious enough to actually
test things, instead of going by 'what always worked' etc.
Since I do my own tinting and my van has two identical rear windows side by side, I figured I owe it to my own curiosity and Ecomodder to test my window tint for myself.
Here are the specs for my lifetime guarantee USA made film (I think Johnson & Johnson brand).
UV Rejected 99%
Visible Light Transmittance 20%
Visible Light Reflected- Exterior 5%
Visible Light Reflected- Interior 5%
Total Solar Energy Rejected 58%
Conditions: sunny winters day 15*C ambient, taken at midday (rear windows facing north - southern hemisphere).
Interior/Exterior Glass surface temperatures:
Black MDF shelves left inside to simulate a dash board etc:
So an 8*C temp reduction for about a $50 investment
