We are building a new custom waterfront house in the Northeast, and the building code and our insurance company require either (a) shutters, (b) impact windows, or (c) precut plywood panels for all windows and doors. Shutters are not feasible, so it is (b) or (c). We are looking at Loewen, Kolbe and Marvin windows.
We are debating not only the significant upcharge, but also whether the substantial added weight of impact glass poses any issues with longevity, maintenance, functionality, etc. Also, I have found various discussions about experiences with impact windows in the southeast, how about the northeast?
Any insights, as well as experience with particular impact Loewen, Kolbe or Marvin models, would be appreciated.
