CosiBLOC Dark Grey: Contemporary Style Meets Superior Light Control

Achieve excellent light control with modern sophistication through CosiBLOC Dark Grey stick-on cellular blackout blinds. Featuring a rich dark grey tone and genuine blackout fabric that prevents light from passing through the material, these innovative honeycomb blinds deliver excellent sleep conditions, privacy, and energy efficiency—all without a single screw or drill hole. The contemporary dark grey colourway brings urban elegance and architectural refinement to bedrooms whilst the blackout performance creates restful conditions ideal for quality sleep.

Revolutionary No-Drill Blackout Technology

CosiBLOC Dark Grey blinds bring professional blackout fabric performance to the revolutionary stick-on system. Using heat-resistant adhesive side channels that bond securely to your window glass, these blinds install in minutes without tools or technical knowledge. Simply peel, stick, and click your blackout blind into place. The robust adhesive ensures reliable long-term performance while remaining completely removable when necessary, making them ideal for rental properties, listed buildings, or anyone seeking damage-free blackout solutions.

Genuine Blackout Fabric in Contemporary Dark Grey

The CosiBLOC Dark Grey fabric features authentic blackout construction that prevents light from penetrating through the material itself. The deep, sophisticated dark grey colourway creates contemporary bedroom aesthetics that work beautifully with modern interior design, industrial-inspired schemes, and minimalist décor. Unlike pure black which can feel heavy or stark, dark grey offers refined depth whilst maintaining a softer, more approachable character that many homeowners prefer in sleeping spaces.

While some ambient light may appear around the edges where the fabric meets the hardware—as with all cellular blind systems—the blackout fabric dramatically reduces light levels compared to light-filtering options, making these blinds particularly effective in master bedrooms, children's rooms, guest bedrooms, and spaces requiring substantial light reduction for restful sleep. The dark grey tone provides excellent light-blocking performance whilst creating more visually nuanced bedroom environments than pure black alternatives.

Enhanced Thermal Efficiency with Blackout Construction

The blackout honeycomb cellular structure of CosiBLOC Dark Grey blinds provides superior thermal performance beyond standard cellular designs. Each sealed cell traps air whilst the blackout backing reflects heat, creating an exceptional insulating barrier directly against your window glass. In winter, this dual-action system prevents heat loss more effectively than single-layer blinds. In summer, the backing reflects solar radiation before it enters your room, helping maintain comfortable sleeping temperatures and reducing cooling costs significantly.

100% Child-Safe Cordless Design

Safety is non-negotiable, particularly in bedrooms and children's spaces where blackout blinds are most needed. CosiBLOC Dark Grey blinds are engineered to be completely cordless, with zero chains, loops, or hanging components that could present entanglement hazards. The intuitive push-pull operation keeps the blind securely in your chosen position without dangerous cords to manage or secure. This makes them the safest possible blackout fabric solution for nurseries, children's bedrooms, and any family home.

Seamless Operation with Tilt and Turn Windows

Traditional blackout blinds create significant challenges on tilt and turn windows, where brackets obstruct window operation. CosiBLOC Dark Grey blinds eliminate this problem entirely. Because they attach directly to the glass pane using adhesive channels, they move effortlessly with the window as it tilts or opens fully. No external brackets interfere with the mechanism, giving you complete functionality of your tilt and turn windows alongside professional blackout fabric coverage.

Perfect for Bifold and French Doors

Bring superior light control to your bifold and French doors with CosiBLOC Dark Grey blinds. Each door panel receives its own individual blind that operates independently as doors open and close. The streamlined 32mm profile from glass to handle maintains smooth door operation without interference. The contemporary dark grey finish complements modern aluminium door frames beautifully, whilst the blackout fabric provides substantial light reduction without compromising your connection to outdoor spaces when doors are open.

Free-Floating Positioning for Custom Control

CosiBLOC Dark Grey blinds feature a tensioned free-floating system allowing positioning anywhere along the window height. Need maximum darkness for sleep while maintaining some morning light awareness? Position the blackout blind to cover the majority of the window whilst leaving a small gap. Require flexible light control throughout the day? Adjust positioning as needed. The blind remains securely wherever you place it, offering versatility impossible with fixed blackout systems.

Hardware Colour Coordination

CosiBLOC Dark Grey blinds are available with your choice of hardware finish to coordinate with your window frames and bedroom scheme:

• White – Striking contrast for light-coloured frames in contemporary schemes
• Anthracite Grey – Seamless tonal harmony for sophisticated monochromatic elegance
• Black – Deep cohesive tones for maximum modern drama

All side channels, top and bottom rails match your selected hardware colour for a cohesive, professionally integrated appearance.
