I am going to be moving soon and went today to really look the new place over. There is a very old barn on the place that is in pretty tough shape but is still usable my sheep. The windows are all okay except on the east side where two of them are broken out. here is my problem - the window frames are not straight. They are very crooked and I don't know how I am going to fix them. I thought about maybe having plexiglass cut and then srewing the pieces to the inside of the window frame. I don't know - has any one else dealt with this and if so what did you do? It dosn't really have to look good - just keepp the wind out.Thanks in advanace!
