Doris,
I buy the brass material for the fins from Copper & Brass Sales http://www.copperandbrass.com They are a national company so they might have an office in NY state. They cut the strips from a 4'x8' sheet of .032 HH (half hard) brass, therefore you can get the fins in a variety of widths, depending on the application. I typically get the, 1/2" and 3/4" wide, but have also used 1" wide at times. You have to tin both sides of the fins with solder before attaching them to the window. Also, it's important to keep a wet rag adjacent to the area you are applying the fins to. I always try to bend them as needed before soldering them to the lead.
Good luck

Roberto
