Did you know that the melted UiPVC (i.e. vinyl) at the corners of the your frame and sashes hold your window together?

If the sashes and frames are made from a heavy, walled, multichambered matching extrusion, the corners will become the strongest part of your windows.

All of A.C. Vinyl windows have all 4 sides of the frame and sash of the windows are heavy walled - approximately 20% - 30% heavier than many of our major competitors. Also all 4 sides of every frame and sash match identically for superiort welding durability and strength. Can you ask the same of our competitors?
