top down/bottom up blinds

Blinds.com offers a variety of style and colors... I like this for texture. many other sites on line.

Will this work on a outside mount?

Dual layer blind, one layer transparent shade, one layer blackout blind. control freely.

Hey There: Our light filtering bottom-up top-down shades install as inside mount to your windows with no header nor strings across your glass. The light filtering fabric is 100% privacy even with lights on at night. But during the day the fabric itself allows for light coming into your rooms and you can lower the top portion for natural light and views while the bottom part stays closed for privacy. Feel free to check out our brand-new website www.fenstermann.com with tons of pictures and videos.
