Gorell windows missing part

Quick Learner from USA
This is my 3rd time trying to send this. My daughter bought this house a year ago and it has Gorell replacement windows. The company went out of business in 2012. Last Christmas it was very cold and windy here and cold air was blowing hard up through the open channel on both sides of these double hung windows of which there are 13. It was very cold in the house. I feel there is a part missing in the channels that would prevent the air infiltration. Wondering if you could verify this and let us know if there is a part to fit these windows and how much they would cost.

There is no part to show you. That is the issue. All of the windows have open channels on each side with nothing in them to stop the air infiltration.

Hello,

There is not generally a specific part or seal used in the window channel but the sashes themselves do have weatherstripping such as wool pile, which is partially visible in your second photo. I would recommend checking all of the weatherstripping to see if it may have worn down over time and needs to be replaced. If so, we would need to see end profile photos and written-out dimensions of each seal to compare to our inventory here. Thank you!

The weatherstripping looks fine. However, there is a hole where the window meets the bottom and I wonder if the air is coming in through that. Have you seen that before and do you know where it leads to, like outside, and if so, how do I prevent air from going into it? Or is it a drain hole? Only thing I can see that might be letting air in. What do you think?

Based on what I can see in your photos, the weatherstripping looks fine and the window looks like it was installed properly. The manufacturer used a coil spring balance system and being a tilt-in window, weather stripping is not required to cover the exposed opening at the top of the sash ends. The square cut-out hole in the sill is for drainage and shouldn't be filled in. Unfortunately, I can't think of any additional measures that you could take to seal the window since all of the original hardware appears to be accounted for and in good condition.
