SmartBlock™ blinds are custom-made to fit your windows perfectly, so getting your measurements right is key to achieving true blackout performance. But don’t worry—our clear, step-by-step guides make it easy, even if you’re not a DIY expert. In fact, many customers go from measuring anxiety to tape-measure boss within minutes Whether you’re fitting your blinds inside the jamb for a clean, built-in look, or outside the jamb due to shallow jambs but still ensuring maximum light block, we’ve got you covered. Download our detailed PDF guides below, or follow the on-screen instructions for the most common option: inside the jamb. Prefer to leave it to the pros? We also offer an optional measuring and installation SERVICE for added peace of mind
With your trusty tape measure in hand, start by measuring the internal width of the window jamb where your SmartBlock™ blind will be installed For the most accurate result, measure the width in three places: at the top, across the middle, and near the bottom of the opening. Windows aren’t always perfectly square, and this simple step helps you catch any variations. Use the smallest of the three measurements—this ensures your SmartBlock™ system will fit neatly inside the frame for a flawless, sealed finish Make sure the tape is held level, and measure from inside edge to inside edge (wood to wood). If you're measuring a wide window or door, now’s a great time to call in a second pair of hands—sweeten the deal with the promise of dinner if needed! Record the smallest width in millimetres. This is what we’ll use to custom-make your complete blackout blind for the perfect fit
Getting the drop (height) measurement right is just as important as the width—especially when it comes to achieving a true blackout result with your SmartBlock™ system. While we include a little extra fabric on the roll, an accurate drop ensures your blind fully seals the window from top to bottom, with no gaps for light to sneak in Using a tape measure, measure from the top inside edge of the jamb to the bottom inside edge (wood to wood), holding the tape straight and perpendicular to the sill. Double-check your reading and note it down in millimetres This precise measurement helps your SmartBlock™ complete blackout blind do exactly what it’s designed for—completely darken the room, eliminate light bleed, and deliver the comfort and privacy you’re after
Click ‘Get a Quote’ and enter your SmartBlock™ blackout blind measurements as width × drop in millimetres (mm). If you're booking a check measure later, or just want a ballpark price before committing, feel free to enter approximate dimensions for now Before any order can be finalised, we’ll need your exact measurements. Supplying accurate sizes ensures your custom blackout blinds are made to fit perfectly—maximising light control, privacy, and insulation
Every SmartBlock™ complete blackout blind is backed by a full 5-year warranty, giving you confidence in a product designed for long-term performance. For motorised SmartBlock™ blinds, the motor and remote control components are covered for 3 years under normal use
This warranty protects against defects in materials and workmanship when the blinds are used and maintained as intended. It does not cover damage resulting from improper installation, misuse, neglect, or accidental damage
With SmartBlock™, you're not only investing in superior room darkening, privacy, and thermal insulation — you're choosing a precision-engineered blackout solution with no compromises, designed to perform in New Zealand conditions
If you’re serious about light control, sleep quality, or immersive home entertainment, SmartBlock™ is the answer. Enjoy full darkness, premium materials, and easy DIY installation—backed by New Zealand’s trusted online blind experts

What makes SmartBlock™ different — and better — than other blackout blind systems?
SmartBlock™ improves on standard blackout blinds with a complete system that includes a fully enclosed cassette box, side channels, and a sealed bottom rail. This advanced design eliminates light gaps for a true room-darkening effect — ideal for bedrooms, media rooms, and shift workers
Unlike many blackout blinds, SmartBlock™ is engineered for performance and style, with precise light control, optional motorisation, and a sleek finish. The result is a high-performance blind system that outperforms traditional roller blinds in both function and appearance
How do SmartBlock™ blackout blinds work?
SmartBlock™ uses a combination of side tracks, a top cassette, and bottom sealing to completely enclose the blind. This stops all outside light from entering the room, unlike standard blackout blinds which often let in light around the edges
How effective are SmartBlock™ blinds at blocking light compared to regular blackout blinds?
Thanks to the innovative cassette housing and side channels, SmartBlock™ blinds offer superior light blocking, eliminating the common gaps around the edges of standard blinds. This advanced design provides the best blackout performance available in New Zealand, ensuring your rooms stay completely dark even during daylight hours
How do the cassette and side channels improve blackout performance?
The cassette box houses the blind fabric neatly at the top, while the side channels tightly hold the fabric edges, preventing light from leaking around the sides. Together, they create a complete light barrier, unlike typical roller blinds that only cover the window area. This design ensures no gaps, no light seepage, and a sleek, modern look
Are SmartBlock™ blackout blinds truly 100% blackout?
Yes, SmartBlock™ is specifically designed to deliver complete blackout performance. Thanks to a fully enclosed system—featuring side tracks, a headbox cassette, and bottom sealing—SmartBlock™ eliminates light gaps around the edges for total darkness. Perfect for bedrooms, nurseries, media rooms, or shift workers
Can I install SmartBlock™ but still have light or air coming into the room?
Yes — while SmartBlock™ blackout blinds are designed to deliver total darkness when fully closed, you still have full control over how much light or air you let in by simply adjusting the blind
If you want natural daylight or ventilation, just raise the blind partially or fully — just like a standard roller blind. Then, when it’s time for complete blackout (for sleeping, shift work, or movie watching), lower it fully and the sealed cassette, side channels, and bottom rail will block out external light and create a dark, thermally efficient space
This flexibility makes SmartBlock™ perfect for bedrooms, nurseries, media rooms, and day sleepers who want to toggle between bright and blackout as needed — without compromising on performance or privacy
Designed for maximum blackout when closed. Custom light control when open
Why do SmartBlock™ blinds cost more than standard blackout blinds?
SmartBlock™ is a premium blackout solution built for complete performance. The added cost reflects the high-precision cassette, side channels, sealed bottom rail, and insulation benefits—features not found in regular blinds. When you’re investing in total darkness, energy savings, and enhanced sleep or media use, SmartBlock™ delivers real value

Are SmartBlock™ blinds suitable for bedrooms, media rooms, or nurseries?
Absolutely. SmartBlock™ blinds are perfect for any space that demands total light control and privacy. Their complete blackout design makes them ideal for bedrooms, home cinemas, and nurseries — creating dark, quiet environments that support restful sleep and enhanced viewing experiences
Are SmartBlock™ blinds suitable for home theatres, media rooms, or home cinemas?
Absolutely. SmartBlock™ blinds are designed to create near-total darkness, making them ideal for media rooms, home theatres, and cinemas. The cassette, side channels, and sealed bottom rail block out ambient light from windows — perfect for improving screen visibility and reducing glare during daytime viewing
Are SmartBlock™ blinds suitable for nurseries and kids’ rooms?
Definitely. With no dangling cords or chains (when you choose the chain-free or motorised option), and complete blackout coverage from light entering the window, SmartBlock™ provides a safe sleep environment for babies and toddlers. Our system also supports earlier bedtime routines and reduces sleep disturbances from early sunrise
Are SmartBlock™ blinds good for shift workers or day sleepers?
Yes. SmartBlock™ blinds are engineered for 360° light sealing with cassette and side channels, eliminating daylight leaks completely. If you work nights or take naps during the day, this system helps create a pitch-black environment that supports restful sleep and better recovery — much better than standard blackout blinds with light bleed in the corners
Can SmartBlock™ blinds help block streetlights or security lights at night?
Yes — SmartBlock™ offers superior light control, even from bright exterior sources. By sealing at the top, sides, and bottom, it prevents diffused streetlights or porch lighting from leaking into your room. This feature is perfect for urban homes or night-sensitive sleepers
Can SmartBlock™ blinds help eliminate early morning light from east‑facing windows?
Yes—SmartBlock™ blinds are tailored for buyers who struggle with early morning sunlight, especially on east-facing windows. Its sealed side channels and fully enclosed cassette system prevent annoying light leaks, even at sunrise. If you're a light sleeper or need reliable blackout during summer mornings, this system delivers
Can I use SmartBlock™ blinds in a rental?
If you are a tenant asking: Yes. They can be installed with minimal impact and removed cleanly if needed. Just check with your landlord or property manager before making changes. When removing you may need to putty and spot paint the screw holes
If you are a property owner asking: Yes, why not. The SmartBlock™ blackout blinds with side tracks are a more expensive solution, when compared to standard blackout blinds, however tenants may well be happy to pay more for thoughtfully placed blinds with complete blackout benefits
Can SmartBlock™ be used on sliding doors or ranch sliders?
Yes — SmartBlock™ can be custom-sized for wide sliding doors or ranch openings, up to approximately 2800 mm wide (manual) or 3000 mm (motorised). The side channel system creates a seamless blackout barrier across large spans. For very wide panels, consider splitting into two blinds for easier handling and better performance
What is the maximum size for a SmartBlock™ blind?
SmartBlock™ blinds can be made up to almost 3000mm wide and 2700mm in drop, depending on fabric choice and operation type (manual or motorised). For wider spans, we suggest splitting the span into two blinds for better coverage and function
What is the minimum width for a SmartBlock™ blind?
The minimum width for a SmartBlock™ blackout blind is typically 400mm, depending on the fabric and control system selected. If you're unsure whether your window is suitable, feel free to contact us for tailored advice
Can SmartBlock™ blinds be installed on any window shape or size?
SmartBlock™ complete blackout blinds are custom-made to fit a wide range of window sizes — including extra-wide or tall frames — but they must be installed on standard rectangular or square windows
Because the SmartBlock™ system relies on precision-fitted cassette boxes and side channels to eliminate light gaps, it is not suitable for arched, circular, or other specialty-shaped windows. For the best light-blocking performance, a clean, square or rectangular opening is essential
What size is the cassette box at the top of a SmartBlock™ blackout blind?
The SmartBlock™ cassette box measures approximately 75mm high by 90mm deep, offering a sleek, compact housing for the blackout blind fabric and components. This discreet cassette box is part of what gives SmartBlock™ its clean, modern look—ideal for complete blackout blinds in bedrooms, media rooms, and home offices
What’s the difference between cassette options for SmartBlock™ blackout blinds?
SmartBlock™ blinds feature a purpose-built cassette system that discreetly houses the fabric roll, ensuring a clean, minimal look with maximum blackout performance—no bulky fascia needed. Our cassette design helps reduce visible light gaps at the top, creating a tighter seal and a more seamless finish within your window frame
You can choose between two cassette box styles: a modern square-face design or a curved profile, both engineered for a sleek architectural finish. For an alternate style, we also offer two valance options: one wooden valance and one fabric-covered valance, giving you flexibility to match your room’s aesthetic
What colour options are available for the SmartBlock™ cassette box, side channels, and bottom rail?
SmartBlock™ blackout blinds come in four premium, powder-coated finishes: White, Black, Anodised Silver, and Cream. These sleek colour options are designed to blend seamlessly with your interior décor while maintaining the integrity of the SmartBlock™ system’s complete blackout performance
Whether you're after a clean, minimalist look or something more classic and timeless, there's a SmartBlock™ colour to match your space
What colour are the plastic components of a SmartBlock™ blind?
The small plastic parts and end caps on SmartBlock™ blackout blinds are carefully colour-matched to your chosen hardware finish—black, white, cream, or silver—ensuring a clean, professional look. This attention to detail helps SmartBlock™ deliver a polished appearance as well as top-tier room darkening performance
What are the bottom rail options for SmartBlock™ blackout blinds?
SmartBlock™ blinds feature a single, purpose-designed bottom rail that is engineered to work seamlessly with the side channels and cassette system. This specialised bottom rail ensures a tight seal at the base of the blind, which is essential for achieving complete blackout performance
Unlike standard roller blinds with multiple bottom rail choices, SmartBlock™ uses a dedicated profile to maintain the integrity of the system and eliminate light bleed. The bottom rail is colour-matched to the system’s cassette box and side channels for a cohesive, built-in appearance
Can I get SmartBlock™ blackout blinds in different fabric colours and textures?
Yes. SmartBlock™ blinds come in a wide selection of premium fabrics, ranging from classic neutrals to textured and designer patterns. You can also choose thermal-backed fabrics for extra insulation. Use our fabric selector tool to filter options by colour, pattern, price, and blackout level — making it easy to find the perfect match for your décor
What fabrics are available for SmartBlock™ blinds?
SmartBlock™ blinds can be paired with a wide range of blockout fabrics, including plain, textured, thermal-backed, and designer styles. All fabrics are chosen for their performance and appearance, allowing you to match your blinds to your interior while enjoying complete blackout
All available fabrics can be viewed here
What are SmartBlock™ blinds made from?
SmartBlock™ blackout blinds are crafted from durable, high-performance fabrics and materials engineered for light control, thermal insulation, and longevity. All fabrics are exclusive to NORMAN, the manufacturer, and the side channels and head box are made from precision aluminium for strength and that sleek, modern look
Can SmartBlock™ blackout blinds be motorised?
Yes! SmartBlock™ blinds are available with motorised operation, making them ideal for media rooms, high windows, or anyone wanting a clean, cord-free look
Manual chain control is also available for a more cost-effective option, or the chain-less option where you raise and lower the blind by hand with the discrete handle secured to the blind's bottom rail
What’s the difference between chain-free, motorised, and chain-driven SmartBlock™ blackout blinds?
SmartBlock™ blackout blinds are available in three control options — chain-driven, chain-free (spring-loaded), and motorised. Each option has distinct advantages, depending on your window placement, budget, and preferences. Here's how they compare:
The most popular and cost-effective choice
Ideal for DIY installation and retrofitting
Includes a child safety clip, but maybe not the best option for young children's bedrooms
A practical choice for standard-sized, easily accessible windows
Features a clean, chain-free appearance with no visible control chains
Safer for homes with young children or pets
Operated by using the handle secured to the bottom rail to raise or lower the blind
Best suited to windows within easy reach
A minimalist option that suits modern interiors, bedrooms, and nurseries
Offers the highest level of convenience with remote-controlled operation
Perfect for large or hard-to-reach windows or rooms where daily manual adjustment isn’t practical
Powered by a rechargeable battery — no electrical wiring required
Professional installation recommended, but confident DIYers can definitely manage as well
We’re here to help. Whether you're after a sleek chain-free look, a smart motorised setup, or a simple chain option, we can guide you to the right choice based on your window size, usage, and room type
What should I consider when choosing the chain-less (non-motorised) option for SmartBlock™ blackout blinds?
SmartBlock™ blinds are available in a chain-less, spring-loaded option—a clean, modern choice for those wanting a chain-free blackout blind with no dangling control chains. However, before selecting this option, here are a few things to consider:
Ease of Use: The blind is operated by gently pulling the handle on the bottom rail to raise or lower it. This works best when the window is easily reachable, both top and bottom
Height Matters: If your window is tall or positioned high on the wall, the chain-free option may not be practical—motorisation may be a better fit in those cases
Stopping Points: The blind can be stopped at any height, but unlike a chain-driven or motorised system, fine-tuning the exact position can take a little more practice
Clean Finish: With no chains or cords, this is the most child-safe and clutter-free manual option available—ideal for bedrooms and nurseries
Durability: Like all SmartBlock™ options, the spring system is robust and built to last with regular use
Still not sure if this is right for your space? Get in touch and we’ll help you decide which blackout blind mechanism is best for your needs
I can't reach the top of my window — can I still use SmartBlock™ blinds?
Absolutely. If your windows are high or hard to reach, you can upgrade your SmartBlock™ blinds with a motorised operation option—perfect for tall windows, stairwells, or accessibility needs. Control your blackout blinds at the touch of a button for effortless light control and privacy. Select the 'motorisation' option when requesting a quote
What’s the difference between the DIY and SERVICE options for SmartBlock™ blinds?

How do SmartBlock™ blackout blinds improve room temperature, insulation, and energy efficiency?
SmartBlock™ complete blackout blinds do more than just block out light — they actively help regulate room temperature and enhance energy efficiency throughout the year
The fully enclosed cassette, side channels, and sealed bottom rail create a tight insulating barrier that reduces heat transfer through your windows. During summer, SmartBlock™ blinds block solar heat gain to keep your space cooler. In winter, they trap warmth inside, reducing heat loss and the need for extra heating
This thermal insulation effect leads to greater comfort indoors and can lower power bills, making SmartBlock™ blinds an excellent choice for energy-conscious homes across New Zealand
What are the noise reduction benefits of SmartBlock™ blinds with side channels?
The snug fit of the side channels not only blocks light but also helps reduce outside noise, making SmartBlock™ blinds a smart choice for urban homes or rooms near busy streets. While not a full soundproof solution, they contribute significantly to a quieter, more comfortable environment
Where are SmartBlock™ blackout blinds made?
SmartBlock™ blackout blinds are manufactured in China by a trusted international supplier (NORMAN) known for precision and quality

How long do SmartBlock™ blackout blinds last?
SmartBlock™ blackout blinds are engineered for longevity. With normal daily use and proper care, you can expect the system—including the cassette, side channels, and blackout fabric—to perform reliably for 10 – 15 years or more. The aluminium hardware is powder‑coated for durability, and the premium blackout fabrics are UV‑stable to resist fading
For added peace of mind, every SmartBlock™ blind comes with a 5‑year product warranty (and 3 years on motor components), covering defects in materials and workmanship. Routine maintenance—such as light dusting and occasional spot‑cleaning—will help maximise the lifespan and keep your SmartBlock™ blinds looking and operating like new
Are SmartBlock™ blinds safe for children and pets?
Yes — SmartBlock™ blackout blinds are designed with safety in mind, making them a great option for homes with children or pets
You can choose a completely chain-free configuration (either manual or motorised), eliminating dangling cords or loops that can pose a hazard. This makes SmartBlock™ a child-safe blind solution that meets modern safety standards
For households with curious toddlers or active pets, the enclosed cassette and secure side channels also help prevent little fingers (or paws!) from getting behind the fabric, ensuring long-term durability and peace of mind
How do I clean and maintain SmartBlock™ blackout blinds?
SmartBlock™ blinds are low-maintenance. A regular dust with a soft cloth or vacuum brush attachment will keep them looking great. For the fabric, spot-clean with a damp cloth and mild detergent—avoid harsh chemicals or soaking
