Replacement window Glass
Do you think, there might be any problem in future or I am better off buying exact window from the local market. Glass size is 5x3 ft.
I would think (hope) that they will send you the instructions to install it right.
I mean, they are sending you the glass!
What brand and type (wood or vinyl) of window is this?
If wood, I would be very carefull how you attach the stop.
One wrong move and "pow", and you will be ordering the glass again.
Be sure you understand the instructions before you remove the old glass.
Changing "glass only" is not something the average person should try. Their giving you the glass at no cost, if you crack it you will be buying a new unit.
