I have a 1962 built home with original sliding aluminum windows. I need to replace the weather stripping as the old weather stripping is shot (I don't think it has been replaced since 1962) and a lot of air seeps in around the window thru the gaps. The weather stripping runs around the frame of the window and under a metal edge that the latch is attached. I can't find any identifier as to the manufacturer of the windows. The weather stripping appears to sit in a shallow channel around the window. My best guess is it is felt or wool pile weather stripping. I was able to remove a small section of it, but it isn't easy to remove. The width of the weather stripping is around 1/4 inch.
What kind of weather stripping is it and how do you remove and install it...especially under the lip that had the window lock?
