I would like to thank you for your question. Both hobbled and flat roman shades can provide comparable room darkening and insulative properties. Details, such as, the fabric, type of lining, and where the shade is mounted in relationship to the window play a role in how insulative and room darkening the shade can be.

If you are thinking of having a custom roman shade(s) made, it is important to work with a certified window fashion consultant. A certified window fashions consultant will assure that your concerns regarding room darkening and insulation are covered. Your biggest concern then would be deciding which style you like best.
