Weather Shield Windows & Doors

Good morning and I hope you had a good weekend. Per my note below, I have older WeatherShield double hung windows with the weather stripping along the bottom of each window that needs replacing.

WeatherShield sent me a short list of suppliers that they think can help, including your company. From visiting your web site it appears as if you guys can help me. I am attaching a few pictures if it helps.
Any suggestions
Thanks,

We have Weathershield replacement double hung windows that we really like. On a couple of the older ones, the weatherstrip on the bottom of the window is getting brittle and old and I would like to replace it. I have pictures if it helps. The strip appears to be in the shape of an inverted "T".
