Hi DIY gurus,
I have a large aluminum clad wood window sash (40w x 53h) in which the IGU has fogged and I am considering replacing the IGU rather than the entire sash. It is from a Marvin bay window unit, which seems to be a good quality unit, in that it is about 23 years old and the wood and aluminum seem to be in excellent shape. I have a good price on a new IGU from a manufacturer, but they won't install it in my wood frame. A local glass shop quoted double the price for the IGU plus TBD
install costs. So I am wondering if I can remove and replace the IGU myself.
It looks like the aluminum cladding is fairly sturdy stuff but I can't say for sure if it is extruded or rolled. The 4 aluminum pieces appear to interlock at the corners, and hold down 4 corresponding vinyl pieces that are sandwiched between the aluminum and the glass.
So, how does one disassemble this to get at the IGU?
Note: I have already read the entire window defog thread, and may go that route, but let's try not to get sidetracked on that topic here.
