CosiBLOC Brown: Natural Warmth Meets Superior Light Control

Achieve excellent light control with organic warmth through CosiBLOC Brown stick-on cellular blackout blinds. Featuring a rich brown 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 warm brown colourway brings natural, earthy sophistication to bedrooms whilst the blackout performance creates restful conditions ideal for quality sleep.

Revolutionary No-Drill Blackout Technology

CosiBLOC Brown 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 Warm Brown

The CosiBLOC Brown fabric features authentic blackout construction that prevents light from penetrating through the material itself. The rich brown colourway enhances bedroom warmth whilst creating a natural, organic aesthetic that works beautifully with wood furnishings, neutral linens, and earth-toned décor schemes. Unlike stark blacks or cool greys, brown brings inviting warmth that makes bedrooms feel cosy and welcoming whilst maintaining superior light-blocking properties.

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 warm brown tone creates a softer nighttime appearance than black, reducing the cave-like effect some find with darker blackout options.

Enhanced Thermal Efficiency with Blackout Construction

The blackout honeycomb cellular structure of CosiBLOC Brown 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 Brown 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 Brown 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 Brown 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 warm brown finish complements traditional timber 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 Brown 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 Brown blinds are available with your choice of hardware finish to coordinate with your window frames and bedroom scheme:

• White – Fresh contrast for light-coloured frames creating bright, airy bedrooms
• Anthracite Grey – Contemporary pairing for modern window frames
• Black – Cohesive natural tones that complement the brown fabric for organic harmony

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