I was watching a show recently and a comment was made about some
material that they were using. It came in 4 x 8 sheets like MDF but
was rated for outdoor use. Anyone know what this stuff is?

I was thinking about looking into possibly using it for a garden
window, which would ultimately be painted. Any comments? Alternate
suggestions?

Thanks in advance.
