We have a house that the Andersen Narrowline 200 windows were installed in the mid 1980’s. I have replaced three widows due to the bottom sash rotting out across the bottom edge. I used a kit by Andersen that converts sashes to tilt windows. I have come across a couple of sills that are rotted, one at edges, I will probably try epoxy to cover those exposed ends. The other is completely rotted out, I am trying to locate an opportunity resin, that I can mix and inject with a large syringe and a tube and hopefully completely fill the void.
