We are going to replace our oversized woodwindows ,but are torn between vinyl and fiberglass. The windows are up to 48" wide and the company that sells the fiberglass windows claims the vinyl one will not hold up. After five years I will have alot of problems. He also showed me letters that were sent to this website, complaining about vinyl windows.
Most complaints were about transfered moisture on the windows, some about worping(sp?) Our windows will be double or single hung and I do not know if considering the size and weight of them, if I should go with fiberglass and pay the higher price. Can anyone Help?? P.S How many companies are in Michigan that makes Fiberglass? Thank you!
