Mixing Marvin Ultimate, Integrity, Infinity in same house
We just purchased a 1917 Tudor, in poor condition, and are replacing about 80 windows. The interior casements are lovely, outside Stucco good condition around windows. Remodel calls for some new windows, but will do mostly insert replacements. We want the real wood on the interior.
We are thinking of using Ultimate Insert Replacement in the main rooms, Integrity for the new windows, and Infinity for the basement and third floor.
The rep told us they should't be mixed in the same house because they will look noticeably different from inside and outside. I had read they were meant to be mixed. Trying to save money where I can. Does anyone who uses or works with Marvin regularly have an opinion about our proposal to mix them?
