Remove window film immediately?
My contractor has been installing my new Anderson Woodwright windows throughout the week. I've come to notice that immediately upon installation he removes the interior and exterior protective film that is affixed to each window from the factory.
My house is far from finished and I've questioned him as to why he doesn't leave the plastic on in order to ensure that the glass remains clean. His contention is that the longer the plastic is left on the harder it is remove, especially during the summer months when the sun beats down on the windows for long periods of time.
