changes to family window

[nass]

Hi, I expose my beginner problem: I don't understand how to change the materials of this family. (I attach the file) the glass is not transparent and I have to change the color of the frame (white painted) .

thanks to all

Try a little.
Hi.

thank you roberto, now you finally see. I think I'll have to do a lot of practice with families. .
can I ask why the walls in the rendering remain greyish despite having selected as finishing material a white matt paint?
Anyway thank you and ...fantastic your sites.
