Glazing Material for Metal Casement Windows

Greetings:

As you see in the pictures, we are keeping the medal (love the casement windows) but will be doing the enduring chore of taking off the "Putty" Glazing, and hoping to replace it with a glazing material you have. But to be honest with you, I don't even know where to start...with what glazing to use?

Can you help guide me to the correct glazing material? Even to what measurements are needed. I do know your time is precious, but if you just point the way, it would be so appreciated.

Kindest Regards,

Lucinda

Dave,

Thank you so much for your precious time, it is very much appreciated. I would have had no idea about the springs, thank you for that info as well. Was hoping I could get the vinyl glaze your store provides, but hey, my fingers will try to make the job look just as beautiful.

Again, thank you for your time,

Kindest Regards,

Lucinda
