Blackout Curtain Fabric

Blackout Curtain Fabric

Blackout curtain fabric is the material of choice whenever a room needs to stay dark, quiet, and comfortable. This category brings together fabrics designed specifically to reduce incoming light while still looking good on the window. You order by the metre, choose the shade that fits your light-blocking needs, and use the fabric either as a standalone curtain or as lining behind an existing one. It's a practical option for bedrooms, home offices, media rooms and any space where daylight needs to be managed rather than just softened.

What sets this fabric apart is the black thread woven into its structure. That construction is what actually does the work: it doesn't just diffuse light like a standard curtain fabric, it blocks a measurable percentage of it. The result is a fabric that combines function with a decent drape, so you're not sacrificing looks for practicality.

How the light-blocking effect works

The blackout performance depends directly on colour. Lighter tones block around 70% of incoming light, which is enough to soften a room without making it pitch dark. Darker shades push that up to roughly 90%, which is what you want in a bedroom or a room with early morning sun. White and ecru variants don't include the black thread in their weave, so they function more as a regular decorative fabric with only a mild blackout benefit. Knowing this distinction upfront helps you pick the right shade for the room instead of assuming all blackout fabric performs the same.

Look, feel and drape

This fabric has a subtle sheen and a firm, substantial handle, which gives curtains a fuller look on the rail rather than a flat, thin appearance. At 220 grams per square metre in 100% polyester, it holds its shape well and drapes evenly, without looking stiff. That weight also makes it a solid choice as curtain lining: you get the added structure and blackout benefit behind a decorative fabric like Canvas Fabric Cotton or a heavier weave such as Burlington Fabrics, both of which pair well with a blackout lining for extra insulation and darkness.

Where it's typically used

• Bedrooms, where darker shades help create a proper sleep environment
• Living rooms and home offices, where lighter tones still cut glare without blocking all daylight
• Hotel rooms, guesthouses and rental properties needing consistent light control
• As lining behind a lighter decorative fabric, including options like Satin Poplin Fabric, to add body and darkening power

Because the fabric is 150 cm wide, it's straightforward to calculate yardage for standard curtain widths without excessive seaming.

Ordering and practical details

You order this blackout curtain fabric by the metre, and it's available in both light and dark colourways to suit different rooms. A fabric sample can be requested first for €0.50, which is worth doing given how much the blackout effect and appearance vary by shade. For larger projects, curtain workrooms or repeat orders, wholesale pricing applies from 6 metres onward. Everything ships from our stock in Tilburg, and the range covers enough shades to work across most interior styles, from neutral off-whites to deep charcoal and black.

In short

Blackout curtain fabric earns its place in this category by doing one job well: controlling light without giving up on appearance. Whether you need a dark, sleep-friendly bedroom or just want to soften glare in a living space, the shade you pick determines how much light gets through. With a sturdy 220 gsm polyester construction, a good drape, and the flexibility to use it standalone or as lining, it's a fabric worth considering for most curtain projects.
