120 mph wind zone - impact glass windows
We are building in a 120 mph wind zone, 1/2 mile from ocean. I am concerned about the cost of impact glass windows busting my budget. I have been told that impact glass windows can cost 2-3 times the cost of same window w/o impact glass. We are working w/ an architect who is sensitive to our budget and only going to use standard size windows. He has suggested that, although typically more expensive, Marvin's hurricane windows are a good choice. Any suggestions on how I might shop around for the best price for Marvin windows?
