The William Morris Duolight Thermal range at Blinds 2go pairs the iconic Arts and Crafts prints of the William Morris collection with a day and night (duolight) construction and a thermal backing - an unusual combination of heritage pattern and functional blind type. There are 14 colourways available, with made-to-measure pricing from £15.80.

Who it suits

The day and night mechanism suits living rooms and sitting rooms where you want to shift between privacy and open light during the day without raising the blind entirely. The alternating sheer and opaque stripes let you admit diffused light while maintaining a degree of privacy, then close the stripes fully for a dimmer effect in the evening. This is a reasonable fit for front rooms that face a busy street, or for those who like the look of a roller blind but want some in-fabric light adjustment.

The thermal backing adds a layer of insulation that can be useful on older or single-glazed windows where heat loss is noticeable - the backing reduces convection from the glass surface, though it will not perform at the level of a cellular or honeycomb blind. If your primary concern is keeping a bedroom genuinely dark in summer, be aware that day and night blinds do not offer full blackout in any position; edge-leak and the nature of the sheer stripe mean some light will enter. For bedrooms where darkness is the priority, a blackout roller or blackout Roman would serve better.

The William Morris print designs do not suit every interior. They are busy, botanically detailed patterns that work well in rooms with neutral walls and traditional or eclectic furnishings. They would look out of place in a contemporary minimal scheme.

The colours

14 colours available

The range covers a broad palette for a patterned collection. The Strawberry Thief design appears in three colourways - Harissa Red, Manor Grey, and Jewel - giving the most choice within a single pattern. Pimpernel runs in three directions too: Blush, Sage, and Teal. The Willow Bough design is available in Mink and Vine, while Honeysuckle and Tulip comes in Grey Blue and Moonstone. Single-colourway prints include Acorn Leaf, Fruit Primrose, and Sunflower Vintage Blue.

Warm tones - Saffron, Harissa Red, Fruit Primrose - sit alongside cooler options in Teal, Manor Grey, and Grey Blue. The Moonstone colourway is a softer off-white neutral. Most of the palette leans towards mid-tones rather than saturated brights, which makes them easier to place in a room without repainting.

With a from-price of £15.80, this range sits at the accessible end of made-to-measure pricing for a patterned blind. The smallest sizes reach the lowest price point; the grid above shows how the cost increases with width and drop, as is standard for made-to-measure blinds where the fabric and mechanism are cut to your exact dimensions.

How it compares

Against a plain roller blind with a thermal backing, the day and night construction adds the light-adjustment function but removes the option of a genuinely opaque fabric. If you need blackout - particularly for a bedroom - a thermally backed blackout roller would be more effective, and typically available in a wider range of fabric weights.

Against a day and night blind without thermal backing, this range offers modest additional insulation that may matter on draughty or single-glazed windows. The William Morris print is the clear distinguishing feature: if the Arts and Crafts aesthetic is the draw, this range has unusually strong pattern choice for the blind type. If pattern is not a priority, a plain duolight fabric would cost less.

Fitting and operation

Day and night blinds operate on a standard roller mechanism - the fabric rolls onto the tube to raise, and the stripe position is adjusted by raising or lowering the blind to align the opaque and sheer bands as needed. Standard inside or outside recess fitting applies. Confirm the minimum recess depth with Blinds 2go before ordering if you plan an inside fit; the roller tube and cassette need sufficient depth to sit clear of the window.
