Duette Thermal Blinds

Duette® blinds are similar in appearance to classic pleated blinds, but on closer inspection reveal some incredible design features.

The hexagonal structure of the fabric traps air passing through helping to maintain comfortable temperatures by reducing the heat in the warmer summer months and the chill in the coldest, winter months.

As well as being state of the art with remote control technology, Duette® blinds are also stylishly streamline; suitable for any room in the home.

Here at Thomas Sanderson, we offer a free design consultation and no obligation quote for customers interested in our Duette® blinds range. If you purchase your thermal blinds from us, you’ll also get a free survey and installation as well as a 5 year guarantee and aftercare on your insulated blinds. Thomas Sanderson offers flexible payment options on all of our Duette® range.

Our Duette® blinds are also compatible with our new PowerView automated blinds system. Create the perfect atmosphere for your home without leaving your seat.  All of this at the touch of a remote, tablet or mobile - anytime, anywhere.

Why choose Duette window blinds

Perfect finish

Our Duette Blinds are available in 20 colours, from Porcelain and brighter Cypress Green to Winter Blue.

Made from a unique fabric, it’s double-layered, hexagonal honeycomb structure traps air between the layers and provides maximum insulation for any window, perfect for all over the home. Also available in dim out fabrics for the ultimate control of light and shade; ideal for the nursery and child’s bedroom.


Fitted to perfection

One of our surveyors will visit you after you have worked through all the options and choices with your designer.


They will want to measure each and every window individually. They will confirm all the measurements taken by your designer to guarantee the insulated blinds and shutters we install in your home are truly bespoke. Just a few millimetres can make all the difference when it comes to window stylings looking and performing at their best, so before we make anything, we ensure we’ve got everything covered.
