Which Marvin for replacement windows?
We need to replace two tall wood windows in front of the house: one triple-window and one double-window.
I know that some companies make PVC replacement windows that are designed specifically for former wood windows.
After many discussions, we wanted to go with fiberglass and Marvin is the only decent company around here with that option.
However, their all-fiberglass line, Infinity, does not have any authorized dealers for residential application where we live. My window guy told us that even if we insist and they agree to let them be installed, there may be a problem with the warranty.
B/c Marvin fiberglass windows are narrower than our current wood windows, the installer would have to add a vinyl brick mold around it, as far as I understand. But the warranty only covers "the window part".
Is this a valid concern?
I wanted all fiber-glass b/c aluminum or not, any clad can eventually fail due to constant compression/expansion. I also really like the look of fiberglass.
However, we are using Marvin sash replacement kits for all other windows in other parts of the house. Does the window style have to match throughout the house? Will anyone even notice?
Also, there was an article linked by someone here (windowwashington, I think) that had a table showing that the expansion coefficient of wood was closer to glass than that of fiberglass. (I cannot find the link and I hope I am not misquoting. :-)) That ignited doubts about the wisdom of going with all-fiberglass for replacement windows.
Should we just go with Marvin aluminum clad and hope for the best?
We need to order next week and any input would be appreciated!
