If it's 5% limo your referring to..definatly not... check your absorbtion rate on your film specs..I usually hang in around the 35% absorbtion myself...wouldn't go over 40% to be safe ...the risk increases if there is any partial shading on the windows or if the windows are very large...others here might have had luck with higher #'s , but I like playing it safe when it comes to thermo :bling

You are asking the wrong question.

Darkness isn't a word tinters use much except when talking to the general public. We use "Visible Light Transmission". This has a number on the laboratory sheets that are available for films. The VLT is not what breaks glass. The "Absorption" value is what breaks glass. You generally find the lower the VLT the higher the absorption on non reflective films, but this is not as true for metallized non reflectives, and shiny films are very low absorbing films. If the absorption is above 49% on a insulated glass unit, you should go to church and light a candle and pray the glass doesn't fog.

Another thing you might want to look at is how much sun light exposure does the glass get. If he get a little morning sun then you can go a little darker, But if he gets a lot of afternoon sun stay with a more appropriate absorbtion.
