Guest metint Posted May 27, 2004 Report Share Posted May 27, 2004 Okay guys and gals? Since many are curious and none really has the time and maybe not the resources, I have just took these readings from a btu meter and a pocket detective visible light meter. Full sun, no clouds? Direct sun = 280-290 btu?s 91% VLT VW qtr glass = 230-240 btu?s *72% VLT Peugeot qtr glass (green) = 140-150 btu?s *54% VLT VL meter calibration glass (grey) = 160-170 btu?s 40% VLT Lexus rx300 qtr glass (reflective) = 80-90 btu?s 25% VLT privacy glass dodge caravan hatch = 40-50 btu?s *Green glass is usually more efficient than grey? that would explain the close btu?s with such a wide VLT margin between the two samples.

Exact-Oh Posted May 27, 2004 Report Share Posted May 27, 2004 I have been too cheap to buy a meter. It would be nice to have the ability to test factory glass and give the customer a more exact figure regarding the resulting darkness in combination with a film.

Guest thetintshop Posted May 28, 2004 Report Share Posted May 28, 2004 I'm still gonna tell people it makes it hotter. I don't think I have to worry about any of them researching it. Link to comment Share on other sites More sharing options...
Guest Zrok Posted May 28, 2004 Report Share Posted May 28, 2004 I'm still gonna tell people it makes it hotter. I don't think I have to worry about any of them researching it. I agree, besides, can't we achieve those numbers (dodge caravan privacy glass) with film that's not as dark? I always thought they HAD to make it that dark to keep out as much heat as a lighter window with film applied. :booga Link to comment Share on other sites More sharing options...
Guest Rama Posted May 28, 2004 Report Share Posted May 28, 2004 Not to say the great metint is wrong, as he most certainly cannot be. BUT! I can say with certainty that even if factory cuts that much, tint still greatly helps. Whenever we get a new Suburban, its usually in the dead of summer and both ac units are blowing their little hearts out. As soon as we tint the whole thing, the heat drastically reduces. So, if its that good, tint just makes it better. Also, did you do a UV test on it as well metint? How much UV is cut? Link to comment Share on other sites More sharing options...
Guest metint Posted May 28, 2004 Report Share Posted May 28, 2004 Since I will be out until June 7th... the question of UV will have to wait until then. I am not disputing the need for film, just giving the numbers to those types of glass to dispell the myth it does not reduce incident solar energy. I will run a check on UV with the same glass and get back to all of you... Meantime me and mrs. will be on the sands of Wakiki until then. Link to comment Share on other sites More sharing options...
Guest Rama Posted May 28, 2004 Report Share Posted May 28, 2004 But I liked that little myth!!! Wakiki? Oh....and I'm stuck in the rain here, at least today. Well, you and your wife have a great time, and bring back plenty of sunshine for the rest of us! Link to comment Share on other sites More sharing options...
hoosierwindowtek Posted June 4, 2004 Report Share Posted June 4, 2004 No disputing that factory tint will reduce heat...just like NR film. However, the numbers don't mean much without film numbers to compare. Just makes sense that a metalized film is going to block more heat than a NR factory tint of same VLT.
