all i know’s anderson, pella, & marvin,,, never had to do anything but sub the work,,, which’s the hot stuff today ? know low-e is the std glass but f/g OR vinyl-covered wood would be your choice ?
btw, if they were conc, i wouldn’t be asking 😉 thanks, guys !
My husband works in glass and hates Anderson windows. If the thermal panes break, he can only replace with Anderson direct and has to replace the entire sash, which in your case will make choosing subs or keeping prices down in the future difficult, and they are overpriced to begin with. We put Marvins in our house, personally like the choices and priced right. Great online catalog and parts are easily ordered even years later. (stain ruined some plastic so I replaced, nothing mechanical)
