Our bifold door blind system also know as SonaCell is a pleated blind system that is ideal for kitchen blinds, conservatory blinds and bespoke glazing with the added luxury of electric blind control via our handsets or wall switches. A truly bespoke electric blind.

Whether you require your blinds for gable windows with a Perfect Fit blinds frame to give you that additional blackout features we have the right solutions for you. Our shaped cellular blinds sometimes also referred to as Duette blinds are essentially two or more pleated blinds back to back so that they form a Honeycomb shape making them perfect blackout blinds for light control. This is beneficial as it helps with energy saving by retaining heat better than most other blinds. Also due to the cellular effect of the fabric the lift cords that are visible on a pleated blind are hidden as they run through the fabric.

All of our shaped triangular window blinds are available with battery, mains or a solar power options and can all be integrated into a smart device via our smart hub system.

Whether you are looking for pleated blinds for bifolds or sliding doors, we’ve got the perfect bespoke solution for you.

Why choose duette blinds for bifolds?



Our standard cellular blinds are available up to 3m wide and 4.5m long. However, we can manufacture blinds in a variety of bespoke shapes and sizes to suit your requirements.


The Honeycomb fabric allows us to fit our blinds on a sleek 37mm headrail which can effortlessly blend into any beautiful interior.

Sound control

The Honeycomb design of the fabric minimises the level of sound coming through your windows, making them ideal for bedrooms.



Hexagonal structures that create an effective 'air pocket' diminish thermal transfer from your window, giving you both protection in those warmer and cooler months.

Low maintenance

A feather-duster or a soft hoover brush is enough to keep your blinds looking as good as new.
