Windows Made of Wood
Replacement windows made with wood is primarily used when the home owner wishes to retain the exact look of the original wood on the home. New ones do have many modern features that will make them superior to the original ones. However, they will degrade over time and the exterior sills and window will need periodic painting.
Wood Windows produce higher R-values, are unaffected by temperature extremes, and are less prone to condensation, but they require considerable maintenance in the form of periodic painting. If the frames are not properly protected from moisture, they can warp, crack, and stick.
Another factor regarding replacing with wood is that they are generally more expensive than other types of replacement product options. In fact, high end wood models will be fairly expensive.
One option you may want to look
into are "clad" products. What this means is the exterior of the window is covered
in either vinyl, or aluminum, thus protecting the sashes from sun and moisture.
You will still have a wood interior, but a more weather resistant exterior.
