The weak point of all-wood windows is the sill which is susceptible to rotting.

Also, if exterior casing is added in the field it must be very carefuly attached to be water tight.

Kolbe & Kolbe makes a Heritage Traditional double-hung model that is wood but the sill and casing are made of Celko, a synthetic/composite material.

For a more historic appearance paired windows should have 3 studs between them.

My 1994 house has Marvin wood windows. They are not divided lite except for a french door. I couldn’t imagine cleaning each lite. I’ve owned the house since 2010. I’ve only painted the windows once and I have reason to believe previous owners never painted them. The trim and some sills are rotting, but the rest is fine. Sashes don’t need repainting often (actually now that I think about it, I’ve never painted some of them). I put in some new windows where none ever existed and only 5ish years later, it was the trim rotting.
So, I learned that I love the wood windows, don’t mind painting them myself, but when I replace the trim, I’ll go with some kind of composite that my contractor used around my newest window. It looks like wood and I admit he was right about it.
Also - solid stain holds up super well on my wood siding, looks just like paint, and when it’s time to stain again (not for 15 years probably), no scraping old paint is necessary.

It is a balance to strike. That said, it is purely on the look/feel argument. There is ZERO compelling reason to go with a wood window, clad or otherwise, given the other material options out there. Given the timber strand they come from, they just don't last as long.

It is the sun and exposure that does the most damage to all wood windows. Unless the south and west elevations have a lot of shade trees/overhangs, the windows/doors are going to need more attention. New growth wood is not as durable. I love all wood windows but only in the right situations. If you have the where withal to take care them, go for your dream of the all wood home

I am in the process of putting my window schedule together. I live in the northeast. Very, very few people up here go with all wood windows, except those that live in historical districts. I received quotes for both clad and all wood from Andersen, Jeld Wen, Marvin, Sierra Pacific, Harvey and Windsor. We are doing a major renovation on a timberframe house which currently has single pane, true divided lite, wood windows (of which some of the panes are broken). We were thinking initially we were going with a clad product, but I just felt it wasn’t going to look right with this particular house. My boyfriend agreed, so he is all in with the future maintenance. To what @Windows on Washington Ltd said, it is primarily an aesthetics decision. Although wood may not last as long, the original windows in my 1936 house were replaced in 2017 - 81 years is plenty long enough for me. Also, if you have the budget, you can get the wood windows in mahogany or other harder wearing woods.

Andersen does not make all wood windows. From the brands you mention above for any type window I would even consider using are Andersen (Woodwright 400 minimum) or Marvin. The balance are all poor choices in terms of quality, fit and finish and customer service. Just my .02.

My thanks to everyone for their input! We are still talking about it but will need to decide soon.

Not a question of "may not", they will not last as long. That is the simple truth.

Comparing timber strand quality from a 1930's window to what is used in current production is also a stark contrast. The reason that windows lasted longer back then...the wood was of a vastly superior density and age in the majority of cases. Also wouldn't touch most of the brands mentioned. Stick with Marvin, much as I hate to blanket endorse a given manufacturer.
