Custom Beech blackout curtains in a heavyweight 357 GSM polyester --- the most powerful light-blocking option in our collection.
The Beech Nocturnal Blackout Curtain is the heavyweight of the DARKROOM collection. At 357 GSM in 100% Polyester, its dense construction does more than block light --- it helps reduce noise transfer and provides a degree of thermal insulation that lighter curtains cannot match. The warm sandy beige inspired by natural wood gives this performance curtain a liveable, considered aesthetic, making it suitable for design-led bedrooms, serious home cinemas, and shift workers' rooms alike.
Made to your exact drop length and panel count, the Beech Nocturnal hangs with the kind of weighted, composed drape that only comes from a truly heavyweight fabric. Custom fit ensures complete window coverage without compromise.
The Nocturnal collection accommodates:
Home theatres and media rooms where absolute darkness is essential
Shift workers who need to sleep in full daylight conditions
Bedrooms in urban environments where noise and light come together
Nurseries where both light and sound disruption need to be minimised
Spaces that benefit from added thermal insulation at the window
Anyone who wants the most robust, high-performance blackout curtain available
Custom-fit to your exact measurements --- made to order for any window size
Beech colourway in a heavyweight 357 GSM Polyester --- the most substantial blackout fabric in the collection
100% light blocking with enhanced noise and thermal insulation as a bonus
80,000 Martindale rub test --- exceptional durability for the most demanding environments
Machine washable at 40°C --- heavy-duty performance without complex care requirements
Perfect for home cinemas, urban bedrooms, and shift workers who sleep in daylight
Multiple top type options to fit any installation
Fabric Information
The Beech Nocturnal is the most heavyweight fabric in the DARKROOM collection --- 100% Polyester at 357 GSM. At this weight, the curtain does significantly more than block light: the dense weave reduces sound transmission through the window and provides thermal insulation that helps stabilise room temperature. The blackout construction is integrated into the weave itself, not added as a coating or backing layer, so performance is consistent across the full panel and does not degrade with washing. The high Martindale rating of 80,000 rubs reflects the fabric's exceptional durability --- suitable even for commercial or high-traffic environments. Machine wash at 40°C, line dry, and low iron as needed.

Frequently Asked Questions
Beech is inspired by the warm sandy colour of natural beech wood — a conscious choice to ensure the Nocturnal does not feel cold or institutional despite its heavyweight, high-performance specification. It is a fabric that is built for serious light blocking but designed to feel liveable.
The Nocturnal is 357 GSM compared to the Nightlong's 328 GSM. The 29 GSM difference represents a meaningfully denser, thicker weave — one that adds sound-dampening and thermal performance that the lighter Nightlong cannot provide.
Heavier curtains require more effort to draw than lighter fabrics, which is why a smooth, good-quality curtain rod or track is important with the Nocturnal. We recommend a rod with low-friction rings or a track system for comfortable daily operation.
Yes. The Nocturnal's dense 357 GSM construction provides a meaningful reduction in sound transmission through the window. While it is not a replacement for acoustic glazing, it is significantly more effective at noise reduction than lighter curtain fabrics.
The Nocturnal is designed for interior use. Conservatories can have very high UV and moisture exposure, which is beyond the intended use environment. For outdoor or semi-outdoor applications, specialist outdoor fabrics would be more appropriate.
Standard domestic curtain fabrics typically achieve 20,000 to 40,000 Martindale rubs. At 80,000, the Nocturnal is rated at roughly double the standard — it is durable enough for commercial environments and built to withstand decades of everyday residential use.
Each panel is 50 inches (140 cm) wide. For wider coverage, you add more panels. There is no wider panel option — the 50-inch width is a consistent standard across the DARKROOM collection.
Yes. For heavy curtains, ensure your curtain rod or track is securely fixed into wall studs or with appropriate wall anchors — not just plaster. A heavyweight curtain, especially across a wide window with multiple panels, can impose significant load on the fixtures.
The dense 357 GSM weave creates a thermal barrier that reduces heat loss through the window in winter and heat gain in summer. It will not eliminate the effect of poorly glazed or single-glazed windows, but it makes a noticeable contribution to room temperature stability.
It is a practical first step, not a replacement. Purpose-built acoustic panels are engineered specifically for sound absorption. The Nocturnal reduces noise transmission meaningfully due to its mass and density, but for professional acoustic treatment, specialist products are required.
