Hi Ken - I have discovered a batch of ancient questions in our Houzz profile, and feel very badly to have been so wildly late in responding. I imagine you are well past requiring input on your topic, but the sidelights we did at this house were made by Kawneer, a very reputable curtain-wall company that did the "storefront" aluminum and glass door/window system at this house. I think that if you Google "storefront" you will find suppliers that do this sort of thing. All best wishes to you, and sorry once again for the time lag.

Good luck with all of your projects.

Paul
