Complete Guide: Blackout Blinds – The Ultimate Choice for Total Darkness
A blackout blind is a window covering designed to block almost all external light, providing perfect darkness for bedrooms, home cinemas, or light-sensitive workspaces. Unlike light-filtering blinds, blackout blinds use dense materials, often with an opaque coating or interlayer, to achieve a blackout rate of 95 to 100%. This comprehensive guide will help you understand the different types, selection criteria, common mistakes to avoid, and maintenance tips to find the ideal blackout blind, whether for a standard window, a skylight, or a no-drill installation.
- Blackout blinds block at least 95% of light, some up to 100%.
- Available in custom, no-drill, track-mounted, and VELUX-specific models.
- Choice depends on window type, installation method (with or without drilling), and budget.
- Regular maintenance (gentle vacuuming, spot cleaning) extends the blind's lifespan.
- Blackout roller blinds with cassette and side channels are the most effective for total darkness.
Different Types of Blackout Blinds
Blackout Roller Blinds
The blackout roller blind is the most common model. It consists of a roll of opaque fabric that unrolls vertically. It can be motorized or manual, and available in a cassette and side channels version to eliminate light leaks on the sides. Blackout roller blinds online are often offered custom-made to perfectly fit your dimensions.
No-Drill Blackout Blinds
The no-drill blackout blind is ideal for renters or those who do not want to make holes in the walls. It attaches using adhesive, suction cups, or a tension system. Less stable than a drilled model, it suits small windows or temporary use.
Track-Mounted Blackout Blinds
The track-mounted blackout blind is mounted on an aluminium or plastic track, often used for roof windows or patio doors. It allows lateral sliding and can be combined with side channels for maximum blackout. Track-mounted models are very effective for sloping windows.
VELUX Blackout Blinds
Specifically designed for VELUX roof windows, the VELUX blackout blind conforms to the sloping shape and installs without drilling using a clip system. Available in roller or pleated versions with a high blackout rate. It is the recommended solution for attic bedrooms.
Custom Blackout Blinds
The custom blackout blind is made to your exact dimensions. It ensures a perfect fit to the window, reducing light gaps. Custom blackout roller blinds are in high demand for non-standard windows. Some manufacturers offer fabric, colour, and control system options.
How to Choose Your Blackout Blind: Essential Criteria
Blackout Rate
The blackout rate measures the percentage of light blocked. For total darkness (bedroom, home cinema), aim for 100% blackout. Quality blackout blinds advertise at least 95%. Look for labels such as 'Blackout' or 'Total Blackout'.
Installation Type
Choose between no-drill blackout blinds (rental, small window) and drilled installation (stability, durability). Track mounting or cassette with side channels improves light tightness.
Dimensions and Custom Fit
For a standard window, a custom blackout blind ensures a perfect fit. Standard models (like IKEA blackout blinds or Leroy Merlin blackout blinds) are economical but may leave gaps. Measure the width and height of your window precisely.
Material and Colour
Blackout fabrics are often coated polyester or multi-layer fabric. Dark colours (black, navy) offer better blackout, but light colours reflect heat. Choose according to your decor.
Budget
Prices range from £15 for a basic no-drill blackout blind to over £150 for a custom blackout roller blind with cassette. Brands like JYSK offer affordable options. Don't hesitate to compare.

Mistakes to Avoid When Buying a Blackout Blind
Neglecting Measurements
A measurement error leads to light gaps. Always take dimensions at multiple points and choose custom if your window is non-standard.
Choosing an Insufficient Blackout Rate
A 90% blackout blind lets through enough light to disturb sleep. Aim for at least 95% for a bedroom, 100% for a home cinema.
Ignoring the Fixing System
A no-drill blackout blind may detach over time or under the fabric's weight. For a durable solution, prefer drilled fixing or a robust track system.
Forgetting Thermal and Acoustic Insulation
Some blackout blinds offer additional insulation. If you want to reduce noise or heat loss, opt for a model with a thermal lining.
Maintenance and Use of Blackout Blinds
Regular Cleaning
Dust your blackout roller blind with a vacuum cleaner fitted with a soft brush once a week. For stains, use a damp cloth with mild detergent, without vigorous rubbing.
Occasional Washing
Some blackout blinds are machine-washable (check the label). Otherwise, dry cleaning is recommended. Avoid hot water which can deform the fabric.
Extending Lifespan
Avoid exposing the blind to excessive humidity (bathroom) or prolonged direct sunlight which could fade the fabric. Use motorization sparingly to preserve the mechanism.
