  1. When I put 3 layers of 30% film together removing the clear plastic, the finished product almost exactly 5%, visually compared to single layer of 5% almost identical. I don't know if it's some type of polarizing where light passes through same places in design? For some reason I only achieved half the darkness putting layered film together from what the math says. Anyone with a light meter able to confirm. FYI 3 layers of Suntek CIR 30% was 5%. I can't explain it just is. I have several samples of 5% from different manufacturers to compare to. I'm not using a light meter. Anyone have a light meter to confirm the math?
  2. Formula (around not perfectly accurate) is base film x next film % (keep going for multiple layers) then x2 gets approximate % of light passing through all layers. Example. Three layers of 30% film would be about 5.4% 30x.3x.3x2=5.4%
  3. Going to buy temporary wax paint color white, cover outside of the windows, removable paint. I ordered a lot of different window film samples to test. Contacted a place to do vinyl wrap they wanted $1000. I bet I could buy the vinyl wrap myself. First I’ll paint the windows immediate relief then I’ll test the film if that fails I’ll wrap.
  4. I’ve even thought about removing the dark glass windows replacing with clear glass, then adding Reflective privacy film inside on clear glass since I’ve been successful reflecting heat back out clear glass. I’ve found no solution through the privacy glass.
  5. You are correct, no disagreement. I was saying the dark glass was hot to the touch, clear glass wasn’t hot to the touch. Yes the heat passes straight through clear glass and dark glass absorbs a lot of the heat and light. My point (i might be in panic from the high heat posting responses not detailed enough, AFTER I placed shiny aluminum foil inside behind clear glass and did the same behind dark glass the clear glass didn’t get hot, the shiny foil successfully reflected the heat through the glass, it was cool to the touch. So with clear glass I could tint shiny or place reflective barrier and it’s not a problem pushing the light back out. I haven’t been able to do that so far with dark factory glass, the glass gets hotter, the inside stays hot, the shiny aluminum gets hot. I understand the heat comes in to both clear and dark glass, with clear glass that heat goes mostly unaffected through until it hits a solid surface inside where it will absorb that light. Totally agree with you. Just so much easier to reflect light back out clear glass. The clear glass wasn’t a problem, I can reflect the heat back out the clear glass doesn’t stop the reflected heat from leaving.
  6. Factory smoke glass making it hotter in direct sunlight. Only the dark smoke glass is hot. Everything else does get warm for sure. The factory dark glass in back about 60+ sq ft of dark glass in the van. Walls 6 ft tall, glass 2+ ft tall full wrap-a-round glass. Glass is the problem. I covered the glass outside with cardboard and temp dropped -6F after glass cooled down. I thought about an awning. It would need to drop down not to interfere with other parked vehicles in parking spots more like pull down window shades. I’m considering installing pull down shades to rest against the glass. Trying to be discrete stealthy camper. roof is steel not aluminum but I covered glass inside with shiny aluminum trying to reflect heat back through the glass, didn’t really help aluminum gets hot like you said transfers heat inside anyway. The insulation backing the aluminum helps a bit. Nothing I did though made much difference. As you said the metal conducts heat from the edges of the hot glass then heats the metal frame around the window like another inside heater. The outer white paint does a good insulating job reducing heat from walls and roof.
  7. Or film that can slow the heat transfer (thermal bridge) slow enough where my ac can keep it cool? Is window film worth the effort if I’m not going to be moving? It’s amazing the white exterior paint deflects so much heat. But the frame around the window 1 ft around super hot. I’m guessing my best option would be to try and get maybe a 40% reflective ceramic. Legal reflectivity 25% I think i can use more reflective tint as dark glass cuts down on reflection?
  8. That’s what I was afraid of. The dark factory glass absorbs huge amount of heat like a solar battery. Transfers heat to the metal frame around the glass too. Quote I attached cardboard over the outside glass which stopped the heat, fixed the issue, looks terrible. I can perforate wrap the glass I guess like transportation bus advertisements . i was wondering IF highly reflective HOUSE TINT would be able to reflect heat back through dark glass. I tried shiny aluminum foil inside and insulated behind the foil inside can’t see out of the windows now. It seem to increase the temperature of the outside window hoping some of that heat would come off but same temperature inside. It’s a little better driving but still super hot. My last option is to put a wall up inside covering windows with 4” insulation and forget the windows. I was hoping there would be some magical window film that can redirect most of the heat back through the dark glass?
  9. 2 weeks ago moved in to my van, Florida, summer, trying to save money. Omg Ford Transit factory privacy glass is cooking me alive. Almost ready to paint over glass. Ac units (45.000btu) full blast 97F inside. Desperate I covered the dark glass on the outside with cardboard to stop sun reaching the dark glass. Once those dark windows heat up it’s dangerous to stay inside. No issues with clear glass. Would ceramic tint reduce the heat inside? Or after 30 min the heat will get past the film? I thought HOUSE FILM might reflect the heat away, but reflect through factory privacy glass??? Can tint solve my issues?
