I have aluminum storm windows on my house. The windows are fine, but the
screens are lousy. The aluminum screen frames were made of aluminum that
was apparently too flimsy. So, what happens is that all the frames are
bowed on at the centers, from the tightness of the screen itself. That
leaves gaps between the screen frame and the window itself, which means
I am constantly getting flys and other insects in the house. The bigger
the window, the worst the screen is bowed.

Temporarily I have put duct tape over these gaps, but I'd like to
replace the screens entirely, especially the large ones.

My question is this: Do they sell aluminum "channel stock" and the
corner parts to make alum screen window frames? I know what is involved
in making them, which is not that difficult. Basically cut the pieces at
a 45deg angle, and hammer in the joiners. The screen itself is applied
with a rubber round bead.

But where would I find this channel stock (and corner pieces) to make
new screens? As long as the thickness is correct for my windows, any
style will work. The screen itself as well as the rubber bead is
available at any hardware store.

Thanks
