Where to get a glass shader

I am looking for a glass shade to use for windows, that works with the standar version of unity. I dont know shader programming, so do anyone know where i can get one for non-comercial use. Or is there a built-in shader i have overlocked that could be used?

Try this one. There is a glass shader at the bottom of the page. Just create a new shader, name the file whatever you want (Unity reads the name in the file so the name displayed in the project view does not matter much). Then copy and paste the shader into that.
