Cellular Blinds

How cellular blinds work

A cellular blind is made from two layers of pleated fabric joined at the folds, creating a row of honeycomb-shaped cells. Those cells hold a layer of air against the window, which is why cellular blinds are often chosen for their insulating qualities.

Comfortable all year

In winter, the trapped air helps reduce the chill near the glass. In summer, the blind helps limit heat coming in. Pair with external screens in very sunny rooms.

Flexible privacy

Top-down, bottom-up versions let you lower the top of the blind for daylight while keeping the bottom covered. That's ideal for bathrooms, landings and street-facing rooms.

For awkward windows

Perfect Fit® cellular blinds sit within the window frame and move with tilt and turn windows and doors. Cellular blinds are also made for roof windows.

Where cellular blinds work best

Because they help hold warmth in, cellular blinds are a sensible choice for rooms that feel cold, such as north-facing bedrooms, conservatories and landings with a large window. They're also neat and compact: when raised, the fabric folds into a slim stack at the top, so they suit smaller windows where you don't want a bulky blind taking up the glass.

In a bathroom or kitchen, we'd guide you towards a fabric that copes with moisture. For a nursery or bedroom, a blackout cellular fabric is usually the better option, and we'll explain how fitting affects any light around the edges.

Choosing a cellular blind fabric

Cellular fabrics come in light-filtering and blackout versions, in a range of soft colours. A light-filtering fabric lets daylight through gently while still giving you privacy, which works well in living rooms and home offices. A blackout fabric is designed to block light for sleeping. If you're torn between the two, a top-down, bottom-up blind can give you more flexibility during the day.

We'll bring the sample books to your home so you can see the colours against your walls and windows. You're also welcome to compare them with pleated blinds, which look similar from the front but have a single layer of fabric.

Cellular blinds can be fitted in the recess, on the wall or in a Perfect Fit® frame, and the choice affects both the look and how much light gets in around the edges. We'll show you each option on your own window.

Measuring and fitting cellular blinds

Cellular blinds are made to measure, so getting the size right matters. We measure and fit every blind ourselves, and we'll check whether a blind inside the recess (the opening the window sits in), on the wall or on the window frame will work best. If you have children at home, we'll also talk you through the safest way to operate the blind; our child safety guide explains more. To get started, book a free home appointment.
