Featuring our exclusive premium DLX fabric with refined textured finish, distinguished pewter grey tone, and genuine blackout construction 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 textured surface adds subtle visual depth whilst the versatile pewter colourway and blackout performance create the perfect blend of contemporary elegance and functional excellence for bedrooms and nurseries.
CosiBLOC DLX Pewter blinds bring premium blackout fabric quality 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 expertise. Simply peel, stick, and click your premium 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 premium blackout solutions.
The CosiBLOC DLX Pewter fabric showcases our exclusive premium textured finish—a subtle striped or grained surface that adds tactile sophistication and visual interest to your windows. Unlike standard smooth blackout fabrics, the DLX texture creates gentle depth and dimension whilst maintaining superior light-blocking properties. The distinguished pewter grey colourway offers refined sophistication—lighter than charcoal yet more substantial than pale grey—creating an elegant neutral that elevates bedroom aesthetics with contemporary style.
The fabric features authentic blackout construction that prevents light from penetrating through the material itself. The pewter tone enhances this performance whilst creating refined bedroom aesthetics that work harmoniously with both modern and transitional décor schemes. 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, nurseries, and spaces requiring substantial light reduction for quality sleep.
The blackout honeycomb cellular structure of CosiBLOC DLX Pewter blinds provides superior thermal performance beyond standard cellular designs. Each sealed cell traps air whilst the premium 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. The premium DLX fabric construction enhances this performance with higher-quality materials that maintain their insulating and light-blocking properties indefinitely.
Safety is non-negotiable, particularly in bedrooms and children's spaces where blackout blinds are most needed. CosiBLOC DLX Pewter 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 premium blackout fabric solution for nurseries, children's bedrooms, and any family home.
Traditional blackout blinds create significant challenges on tilt and turn windows, where brackets obstruct window operation. CosiBLOC DLX Pewter 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 premium blackout fabric coverage with refined textured aesthetics.
Bring premium blackout control to your bifold and French doors with CosiBLOC DLX Pewter 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 sophisticated pewter grey finish complements both modern aluminium and traditional timber door frames, whilst the textured DLX blackout fabric provides substantial light reduction and luxury aesthetics without compromising your connection to outdoor spaces when doors are open.
CosiBLOC DLX Pewter 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.

Our stick-on cellular blinds are completely child safe by design. With no cords, chains, or loops of any kind, they eliminate the risk of entanglement that traditional blinds can pose to children and pets. The blinds are operated by simply pushing or pulling the bottom rail to your desired position, where they will lock securely in place. This intuitive, hands-on operation means there are no hazardous components whatsoever, giving you complete peace of mind in any room of your home.
Because stick-on cellular blinds are cordless, they are the ideal choice for children's bedrooms, nurseries, and playrooms. You can position furniture, including beds and cots, anywhere near the window without safety concerns. The simple push-and-pull mechanism is safe for children to use under supervision, helping them learn independence while remaining completely secure.
At newblinds.co.uk, child safety is of paramount importance. If left hanging freely, chains and cords from blinds can pose a direct threat to children. This is why we designed our stick-on cellular blinds to be completely cordless and "safe by design" from the ground up. With no cords or chains required for operation, these blinds represent the safest possible window covering solution for families with young children.
