My apologies for not being more thorough.
I have the shrink wrap, clear film covering the inside of the DP windows
to cut down on drafts and window condensation.
On the _outside_ of the DP windows, I installed tinted window film and
read it wasn't meant for DP windows.
Is the heat build up the same on the outside, as it is on the inside?
Will my windows break?
The one day it was sunny here, I could really tell a difference in how
well it blocked the heat from the sun, between a tinted and untinted
window. Is there a safe product to use?
Thanks for the info.
