large vinyl awning window
I am enlarging a kitchen window - the size will be 50" wide by 60" high. Have got three quotes for awning windows. Here's the thing. Pella will do a 50x60 awning in fibreglass in their impervia duracast line, but not in that size in vinyl. One other reputable local manufacturer, North Star (I'm in Canada), will NOT do an awning at this size. But I got a third quote from another installer who will do a 50x60 awning in vinyl - but I'm a bit sceptical. He also came in at half the price of the others and some warning bells went off.
So my question is, can anyone see anything wrong with a 50x60 awning window in vinyl?
The other option is I do a fixed transom above a smaller awning. The problem with this is you get a 7-8 inch space between the windows, which will reduce the awning to about 38 inches high.
Finally (if anyone's reading this far) any thoughts on Pella impervia? They quoted 40% more expensive than North Star.
Thanks a million!
