I’m new to the forum. I’m rebuilding a 800sqft 1920s house, reusing lots of the old fir and larch floor and trim, adding some post and beam, lots of insulation, radiant hydronic heating and solar water heating.
I’m looking for information and product to weatherstrip some wood casements. They are fir sash and jamb with clear stain that were recycled from another house (but fairly new). They currently have some vinyl tube weatherstrip that fits into a groove in the sash. The problem is that the tubes don’t meet in a lot of the corners and also the sash doesn’t overlap the jamb at all, so when driving rains hit them a little bit of water leeks into the corners. I’m sure there must be better weatherstrip on the market?? I also am wondering if I could extend the sash out toward the exterior so that it overlaps the jamb and covers the gap and weatherstrip? Or would the new weatherstrip be enough? The climate is generally sunny and dry in the summer with lots of snow in the winter. The exterior is still unfinished and I’m not worried about perfect look – performance is the goal. I can attach a photo if this isn’t clear.

Visit a local glass shop and see what sort of weatherstipping they have. Most shops should have a variety.
Google up "Resource Conservation Technology" and check out their weatherstripping products, in the Energy Efficient Building area.
I second RCT. They have an asst. of bulb sizes in silicone, very flexible and good stuff.
I just recently was repairing this very similar situation, 1913 home and the wood casements were arch topped. Upon re-glueing the sash, they no longer fit well in the opening , this made the weather strip an issue. I routed new grooves in the jamb at the rabbet that the window stops againt ( with the RCT, router for thier product) but I still had a large gap, due to window shrinking and framing/jamb shrinking over the years.
I laminated ( painted poplar sash in this case) thin veneers of wood and fixed it while glue dried with temp. staples. Temp. so I could plane and sand the build up to my exact need. It was tedious, being an arch top, and working off roof jacks 3 stories up, these were on barrel dormers on a slate roof.
It sounds as if you have te groove already, so just get larger bulb size, and you'll soon see if you need to add to the sash.
