Fabric Information
The Slate Stonewall is woven from 96% Polyester and 4% Linen --- a blend that captures the organic, textured surface character of linen while retaining the practical benefits of a performance polyester. The linen content gives the fabric its distinctive slightly irregular, stone-like texture and a warmth that flat synthetics cannot replicate. At 344 GSM, it hangs with a relaxed, weighted composure. Despite its natural-looking surface, it is a full blackout curtain: light block is built into the fabric structure rather than applied as a separate coating, ensuring consistent performance across the whole panel. Tested to 45,000 Martindale rubs, it is durable enough for everyday use in bedrooms and living rooms alike. Machine wash at 40°C, line dry, and low iron if required.
Integrated blackout construction --- no separate backing layer
45,000 Martindale rub test --- durable for everyday use in living rooms and bedrooms
Machine washable at 40°C --- all the appeal of linen with none of the delicate upkeep
Low iron if needed
Multiple top type options --- Grommet, Tab Top, Rod Pocket, Sleeve Top
Available in 12 coordinating colourways across the Stonewall range
Frequently Asked Questions
All three are grey, but each occupies a different position. Ash is a light cool grey. Shadow is a deep moody mid-grey. Slate is a sophisticated blue-toned dark grey — it shares darkness with Shadow but has a more distinct blue inflection that gives it a different character, closer to the blue-grey family than pure grey.
Yes. The blue-grey of Slate coordinates naturally with navy, blue, and teal accent colours in bedding, cushions, or artwork. It sits within the same colour family while being tonal and understated enough to function as a background rather than a competing element.
Yes — texture is generally more visible on darker fabrics because the linen weave's slight irregularity creates small light and shadow contrasts on the surface. On Slate, this creates a particularly rich, tactile surface quality that is one of the most distinctive effects in the Stonewall collection.
Yes — Slate is one of the strongest choices for cool-toned, contemporary apartments. It works especially well with grey-toned marble surfaces, polished concrete floors, chrome hardware, and grey upholstery. The blue note in Slate adds depth without warmth.
The SKU listed (206928C) refers to the Stonewall collection. Individual colourway selection is made during order configuration. The collection SKU applies across all 12 Stonewall colourways — the difference between them is colour only, not fabric specification.
Yes. Slate and grey joinery can create a beautifully layered, tonal interior when managed well. The key is using Slate as the window element against grey walls or joinery rather than having everything at the same dark value — some tonal variation keeps the interior from feeling flat.
Colour always looks different depending on the direction of light, the room's other colours, and the artificial lighting used. We recommend ordering a sample and viewing it in the specific room where you plan to use it before placing your order.

The linen-look texture of the Stonewall provides warmth at a tactile level that counteracts any visual coolness from the blue tone. In practice, Slate reads as sophisticated rather than cold — particularly when paired with warm lighting and soft furnishings.
Yes — a black or charcoal rod is an excellent choice with Slate. The dark metal echoes the depth of the fabric and creates a cohesive, contemporary look. Matte black rods in particular suit the organic surface of the Stonewall very well.
