My husband and I replaced all of our windows with Viwinco impact glass windows. We've already noticed a difference in them providing better insulation and sound proofing. We had an issue with getting a few of our windows to close all the way to lock right after we had them installed, but Colin Baker (a Viwinco sales rep) responded quickly to our issue and came out to inspect the problem explaining why it does that sometimes when the windows are brand new. He showed us how to open/close them while they were being "broken in" and also lubricated the windows for easy opening/closing. Great customer service and great quality windows. I would definitely recommend these windows.
