I have installed film tint on the glass in my house.

of course, the tint film is usually installed on the inside.

however, i have some spare tint film (i bought a roll) and was wondering for extra protection from sun, can (should) i put another layer of tint on the outside as well for the dining windows ?

minimal rain on the outside part....

so if i put a 2nd layer outside (after inside already install 1st layer), ok ke ? cooler kan ?

hope to get your feedback ...

But why you don't want to double layer inside?
Tint wasn't made to withstand the weather from outside physically, or else you'll be seeing cars with tint installed outside already

i bought a roll of tint film, and after installation, there is still spare.

you think its ok to double layer inside ? i didn't think of it........

Usually is double layer inside not outside, although I never try before but I presume is because they are not made to withstands weather physically.

yes, the seller told me can install the tint outside. The only downside is you will see silver color tint from outside the house, unless the tint you bought both sides also same color.

You can double layer or triple inside just nights time totally see no things , cooler if the tint are bright colors like chrome technically, mine is black the whole glass is hot to touch when facing sun so regret 😂
