I have used plexiglass for years. They rattle, wind blows in around them,you can not seal them up to keep wasp out at all. I bought 3 windows ( sliders ) just like the one that the hunted sales on his web page. Now there have been 6 guys on the lease gone to this window, they are great. I will never go back to home made windows.
No I do not know The Hunted ( wish I did ) nor do I make any thing from him. He sales a GREAT window.
This is the window that we use. http://www.deerviewwindows.com/deerstandwindowsdoor/sliderwindow.html
