CosiBLOC Grey: Superior Room Darkening Without the Drill

Discover exceptional light control and modern style with CosiBLOC Grey stick-on cellular blackout blinds. Combining sophisticated grey tones with blackout fabric technology, these innovative honeycomb blinds install in minutes without drilling, offering superior room darkening for restful sleep while maintaining excellent thermal efficiency and complete child safety.

The No-Drill Blackout Solution

CosiBLOC Grey blinds revolutionise bedroom window treatments with heat-resistant adhesive side channels that bond directly to your window glass. Installation requires no tools, no screws, and no drilling whatsoever. Simply peel, stick, and secure your blind into the channels for instant blackout performance. The durable adhesive system ensures reliable, long-term hold while remaining completely removable, making these blinds ideal for rental properties, period homes, or any space where preserving window frames is essential.

Contemporary Grey Meets Blackout Fabric

The CosiBLOC Grey colourway delivers sophisticated modern aesthetics alongside exceptional light-blocking capability. This versatile mid-grey tone complements contemporary interiors, providing a refined alternative to stark black or basic white options. The blackout cellular fabric construction prevents light from penetrating through the material itself, creating a significantly darkened environment ideal for bedrooms, nurseries, and spaces requiring substantial light reduction. Please note that while the fabric itself is blackout grade, some minimal light ingress may occur around the edges where the fabric meets the hardware channels. This is characteristic of stick-on blind systems and does not diminish their excellent room-darkening performance.

Engineered for Bedroom Darkening

Unlike light-filtering cellular blinds, CosiBLOC Grey features specialist blackout honeycomb cells with light-blocking properties throughout the entire fabric structure. When fully closed, these blinds dramatically reduce room brightness by preventing light from passing through the fabric, effectively blocking out street lights, early morning sun, and external illumination. The result is a bedroom environment conducive to deep, restorative sleep, particularly beneficial for shift workers, light-sensitive sleepers, or creating optimal nap conditions for children.

Superior Thermal Efficiency

The blackout honeycomb cellular design of CosiBLOC Grey blinds provides exceptional insulation beyond standard window coverings. Each air-trapping cell creates a thermal barrier directly against your window glass, preventing heat loss during winter months and blocking solar heat gain in summer. This advanced insulation reduces heating and cooling costs while maintaining comfortable bedroom temperatures year-round. The blackout fabric adds an additional insulation layer, making these blinds particularly effective for energy conservation.

Completely Safe for Nurseries and Children's Rooms

Safety is paramount in spaces where children sleep. CosiBLOC Grey blinds are engineered without any cords, chains, or looped components, eliminating all strangulation risks associated with traditional window coverings. The cordless push-pull operation is intuitive and safe, providing total peace of mind for parents. Position beds, cots, and furniture anywhere near windows without safety concerns, knowing your window treatments pose zero hazards to curious children or pets.

Perfect for Tilt and Turn Window Darkening

Traditional blackout blinds often fail on tilt and turn windows, but CosiBLOC Grey blinds excel in this application. Adhesive mounting directly onto the glass pane means the blind moves seamlessly with the window as it tilts or opens. No external brackets interfere with window operation, giving you complete tilt and turn functionality alongside superior room-darkening performance. This makes them ideal for modern homes, apartments, and new-build properties featuring tilt and turn windows in bedrooms.

Bifold and French Door Privacy

Create effective light control on bifold and French doors with CosiBLOC Grey blinds. Each door panel receives an individual blind that operates independently, allowing doors to open and close freely while maintaining privacy and light reduction. The slim 32mm profile ensures smooth door operation without interference. Perfect for bedroom patio doors or garden rooms requiring darkness, these blinds provide versatility without compromising on blackout fabric performance.

Flexible Positioning for Light Control

CosiBLOC Grey blinds feature a free-floating tensioned system allowing positioning anywhere along the window pane. Pull down from the top for upper light blocking while maintaining lower window privacy, or push up from the bottom to reduce low evening sun while preserving upper daylight. The blind stays securely in your chosen position, providing precise light management throughout the day. This flexibility is particularly valuable for bedrooms requiring different light levels for reading, sleeping, or morning routines.

Hardware Colour Coordination

CosiBLOC Grey blinds offer three hardware finish options to complement your window frames:

• White – Clean and classic for white uPVC and painted timber frames
• Anthracite Grey – Modern coordination for grey aluminium and contemporary windows
• Black – Bold, dramatic finish for architectural contrast and black window frames

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