Impervia vs Integrity
I've done extensive searching on the web for reviews regarding Pella Impervia and Marvin Integrity windows and patio doors. Most of the information seems to be at least 5 years old. I am looking for more current experiences and information. We are looking at both of these windows and would appreciate any insight - pros and cons - regarding these fiberglass windows and patio doors. This is for a renovation that will be mostly new construction.
