Are honeycomb blinds see-through at night?

Because Duette® honeycomb blinds are made from two or more layers of fabric, it isn't easy to see through them at night, unless you deliberately choose a sheer fabric. For this reason, they are ideal for windows that may be overlooked. Unlike some other styles of Pleated blinds, Duette® blinds do not have visible holes. The lack of holes means that they can be thermal blackout blinds when you select a blackout fabric.

Are Duette® blinds child-safe?

Yes, Duette® blinds are inherently child-safe by design, so they are perfect for a child's bedroom or nursery. They are operated by a simple tab control, rather than loose hanging cords. If you choose to upgrade to electric blinds, they can be controlled with a remote control or even a smart device, such as Amazon Alexa or Google Home.

How to clean Duette® blinds

The easiest way to keep your Duette® blinds clean is to use the soft brush attachment of a vacuum cleaner, designed for soft furnishings and upholstery. You could also use a feather duster or a damp cloth. It's important not to press too hard when cleaning your blinds, as you risk damaging the unique honeycomb structure.

Yes. Duette® blinds are available in a wide selection of colours and fabrics, giving you total control over the finished look. At your in-home appointment, your design consultant will show you the full range. They can also advise on which designs may suit your window or door. For example, in a bedroom, you may want to consider blackout blinds, to prevent light coming in.

How are Duette® blinds fitted?

Duette® blinds are fitted at door or window frames using a patented tension technique, which doesn't use loose or free-hanging cords to operate the blinds. For this reason, they are inherently child-safe by design. The blinds can be fitted in many different shaped windows and are perfect for different window sizes and large expanses of glass. If you have a bay window or gable end window, they can be made to fit perfectly. They are also ideal for doors, including patio doors and bi-folds.

Are Duette® blinds the same as acoustic blinds or noise-reducing blinds?

Duette® blinds help to provide acoustic control and reduce background noise. As well as being energy efficient, the unique honeycomb structure of the blinds absorbs up to 45% of background noise, improving the acoustics in your room.
