Combining soft sand tones with blackout fabric technology, these innovative honeycomb blinds install in minutes without drilling, offering superior room darkening for peaceful sleep while maintaining excellent thermal efficiency and complete child safety.
CosiBLOC Sand blinds transform 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.
The CosiBLOC Sand colourway delivers natural, earthy sophistication alongside exceptional light-blocking capability. This warm, neutral sand tone creates a calming, organic ambiance while providing serious blackout performance, perfect for bedrooms seeking a natural aesthetic with effective light control. 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.
Unlike light-filtering cellular blinds, CosiBLOC Sand 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 young children.
The blackout honeycomb cellular design of CosiBLOC Sand 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.
Safety is paramount in spaces where children sleep. CosiBLOC Sand 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.
Traditional blackout blinds often fail on tilt and turn windows, but CosiBLOC Sand 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.
Create effective light control on bifold and French doors with CosiBLOC Sand 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.
CosiBLOC Sand 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.
CosiBLOC Sand blinds offer three hardware finish options to complement your window frames:
All side channels, top rails, and bottom rails match your selected hardware colour for a cohesive, integrated appearance.

Watch our step-by-step video guide to see just how simple it is to install your stick-on honeycomb blinds. No drilling required, no special tools needed – just follow along and have your new blinds fitted in minutes. Our clear instructions will guide you through the entire process, from unpacking to the finishing touches.

Installation is remarkably simple and takes just minutes per window. First, clean your glass thoroughly with glass cleaner and allow to dry completely. Measure and mark the position for your side channels, then peel the protective backing from the adhesive strips and press firmly onto the glass. Once both channels are secure, simply clip your blind into the channels—you'll hear a satisfying click when it's properly engaged. No tools, no drilling, no mess. Full step-by-step instructions are included with your blind, and our video guide walks you through the entire process. No. Stick-on cellular blinds use a professional-grade adhesive that bonds securely to glass but is designed for clean removal when needed. When you're ready to remove the blinds, simply warm the adhesive slightly with a hairdryer and peel away gently. Any residual adhesive can be removed with methylated spirits or adhesive remover. The system is specifically engineered to leave no marks, damage, or residue on your glass or frames, making them perfect for rental properties or anyone who values their windows. For optimal adhesion and performance, stick-on cellular blinds require a smooth, flat glass surface. Textured, patterned, or heavily frosted glass may not provide sufficient contact area for the adhesive channels to bond securely. If you have textured glass, we recommend measuring a small section to confirm the surface is smooth enough for adhesive application. Contact our customer service team if you're unsure about your glass type. Stick On Blinds have a slim profile, projecting just 32mm from the glass surface to the outside of the profile. This compact design ensures they don't interfere with most window furniture, curtains, or door operation. However, for bifold doors with very tight folding clearances, it's important to check this 32mm projection against your door's frame depth and closing mechanism to ensure full compatibility. If the handle is folded - the overall projection from glass suface is 42mm (32mm blind profile + 10mm handle) If the handle is not folded - the overall projection from glass surface is 62mm (32mm blind profile + 30mm handle)How do I install Stick On Blinds?

You should also consider that the operating handle projects out from the hem bar. It's a folding handle, so how far it projects depends on whether the handle is folded or not.
Absolutely—this is where stick-on cellular blinds truly excel. Because they attach directly to the glass pane rather than the window frame, they move with the window as it tilts and turns. This eliminates the common problem of brackets and mechanisms interfering with the window's operation. You can tilt your window for ventilation or open it fully for cleaning, and the blind moves seamlessly with the glass, maintaining perfect coverage and operation in any window position. Yes, stick-on cellular blinds are excellent for bifold and French doors. Each door panel receives its own individual blind that operates independently. The key consideration is the 32mm projection from glass to handle—you need to ensure your bifold doors have sufficient clearance to fold flat with this additional depth. For most modern bifold door systems, this isn't an issue, but we recommend checking your door's folding mechanism if you have a particularly compact installation. French doors work perfectly as the doors open outward rather than folding together. Yes, stick-on cellular blinds work excellently on uPVC windows. The adhesive channels bond securely to the glass pane within your uPVC frame. They're particularly beneficial for uPVC windows because they require no drilling into the frame material, preserving your windows' weatherproofing and warranty. They're also ideal for uPVC tilt and turn windows where traditional blinds simply won't work. Stick-on cellular blinds are an excellent choice for conservatory windows, offering solar control and privacy without the complexity of traditional conservatory blind systems. The cellular honeycomb structure provides valuable thermal insulation, helping to moderate temperature extremes that conservatories commonly experience. Available in both light-filtering and blackout options, they manage sunlight effectively while maintaining brightness or providing complete darkness as needed. They're particularly effective on vertical conservatory windows and doors, though they're not suitable for angled roof glazing. Are these blinds suitable for tilt and turn windows?

Stick-on cellular blinds use an intuitive push-pull operation with a built-in handle at the bottom rail. Simply grasp the handle and push upward to raise the blind, or pull downward to lower it. Thanks to the tensioned system, the blind will stay securely in any position you choose—halfway up, three-quarters down, or anywhere in between. There are no cords to pull, chains to operate, or mechanisms to maintain. This cordless design is not only incredibly convenient but also completely child-safe. Yes, this is one of the most versatile features of stick-on cellular blinds. The free-floating tensioned system allows you to position the blind anywhere along the window height. Want morning privacy while letting light in from above? Position it at the bottom. Need to block glare from the top? Pull it down from above. This flexibility means you can adjust privacy and light control throughout the day without compromising either, making them far more versatile than traditional fixed-position blinds. Absolutely. Stick-on cellular blinds are child-safe by design, not by addition. There are no cords, chains, or loops of any kind—the primary hazards in traditional blind systems. The simple push-pull handle operation eliminates all entanglement risks, making these blinds suitable for every room in your home, including children's bedrooms, nurseries, and playrooms. You can position furniture, including cots and beds, anywhere near the window without safety concerns. This cordless design also meets and exceeds all UK child safety regulations for window blinds.How do I operate the blinds?

The level of privacy depends on which fabric type you choose. Light-filtering (CosiSHADE) blinds offer excellent daytime privacy while filtering natural light beautifully. The cellular honeycomb structure diffuses incoming light, preventing clear views into your room from outside while maintaining a bright, naturally lit interior. During daylight hours, you can see light and general outdoor shapes, but details and people inside remain completely obscured from external view. At night with interior lights on, silhouettes may be visible. Blackout (CosiBLOC) blinds block light through the fabric itself, providing superior privacy both day and night, though minimal light may appear around the edges where the blind meets the hardware. This depends on your fabric choice. Light-filtering (CosiSHADE) blinds are designed to soften and diffuse natural daylight while providing privacy, creating a warm, welcoming ambiance. They reduce light levels significantly but won't create complete darkness. Blackout (CosiBLOC) blinds feature specialized blackout fabric that blocks light through the material itself, making them ideal for bedrooms, nurseries, or media rooms where darkness is desired. However, please note that some minimal light may appear around the edges where fabric meets hardware—this is normal for all window blinds and does not indicate a fault. The honeycomb cellular structure creates thousands of tiny air pockets that act as an insulating barrier directly against your window glass—the primary source of heat loss in any building. In winter, these air pockets trap warm air and prevent it from escaping through the glass, reducing heating costs. In summer, they reflect solar heat before it enters your room, keeping spaces cooler and reducing air conditioning needs. Many customers report noticeable improvements in room comfort and reductions in energy bills. The thermal efficiency is enhanced because the blinds sit directly against the glass, creating an optimal insulating layer at the source of heat transfer. While not specifically designed as acoustic blinds, the honeycomb cellular structure does provide some sound dampening properties. The air pockets within the cells can help absorb and reduce sound transmission through your windows, particularly with higher-frequency noises like traffic or voices. However, for significant noise reduction, you would need specialist acoustic treatments. The blinds will create a noticeable but modest improvement in sound insulation, which many customers appreciate as an additional benefit alongside the thermal and privacy properties.

Stick-on cellular blinds require minimal maintenance. For regular cleaning, use a feather duster or vacuum with a soft brush attachment to remove surface dust from the pleated fabric. For marks or spots, use a slightly damp cloth with mild soapy water, dabbing gently rather than rubbing. Avoid saturating the fabric or using harsh chemicals, as these may affect the honeycomb structure or colour. The blinds can be unclipped from their channels for more thorough cleaning if needed, then simply clicked back into place. Yes, stick-on cellular blinds can be unclipped from their side channels for window cleaning or blind maintenance. Simply grasp the blind firmly and pull away from one channel at a time to release the clips. To refit, align the blind with the channels and press firmly until you hear the click of proper engagement. The adhesive channels themselves can also be removed if you're moving house or redecorating, though this is typically a one-time installation. When removing adhesive channels, warm them with a hairdryer first to soften the adhesive for easier, cleaner removal. How do I clean Stick On Blinds?

Measuring is straightforward—you're measuring the glass size, not the frame. Measure the width of your glass pane at the top, middle, and bottom, and use the narrowest measurement. Measure the height (drop) at the left, middle, and right, and use the shortest measurement. We recommend measuring to the nearest millimetre for the most accurate fit. The blind should fit neatly within your glass area with the side channels positioned on the glass surface. Download our detailed measuring guide from the product page for step-by-step instructions with helpful diagrams, or watch our measuring video for a visual walkthrough. Stick-on cellular blinds are custom-made to your exact measurements, providing a perfect fit for your specific windows. Minimum and maximum size restrictions apply based on the blind's structural capabilities. If the sizes you are looking for are outside of those allowed by our website, an alternative product may be better suited.
