Hi there – I am new to the channel. Wanted to run a question by some of you experts out there. I am replacing windows in my home with replacement windows and am trying to figure out the best way to put trim on the exterior. As a side note, my neighbor hired a contractor to install his windows and put a nice vinyl trim around his (pictured). Both our homes are the same age and have aluminum siding. If someone could help me figure out the material they used on his windows that would be very helpful. I currently have a temporary PVC trim around my window to protect it from the elements while I figure out a more permanent solution. I know mine is a hack job and it shows.

Thanks for the help!
