I'm on the board in my condo association and have been trying for some time to rectify the heat situation in the front lobby of the building I live in. There are 2 buildings, about 30 years old, no AC, and stairs (no elevator).

It was almost agreed to get a quote from our very talented handyman to install the film and give us a quote. But then he came back and said that the stuff doesn't last.

It would keep SO much heat out of the building!

Anyway - have you used window film? Did you install it yourself or have a professional do it? Did it last? What do you think?

Thanks.
