Snap-in (??) Double-Paned Windows
I would like to know where in or around San Francisco I can buy windows that you snap-in (or otherwise adhere) to your existing window frames to make double-paned windows. We are renting, and therefore do not want to install entirely new windows. Any ideas? Also, any experience you can share with these? We would be using them to block out sound and hopefully keep drafts out. Thanks.
