The Bosa Magnolia Battery / Solar Blackout Cassette Blind is our Total Blackout solution to cast your room into complete darkness. The barrel and blackout fabric are neatly enclosed within the aluminium headbox and side channels ensure the edge of the fabric stays in place. As a result, this blind creates a light omitting seal, blocking light from entering the room.
Our total blackout cassette blinds are perfect for any room you are looking to banish daylight. From Bedrooms to Home Cinema Rooms, our cassette blinds will provide you with complete darkness all year round.
The Bosa Magnolia fabric is a Cream coloured blackout fabric made from Polyester. It is operated by a motor that is enclosed within the barrel of the blind. This cassette blind can go to a maximum width of 2650mm.
Due to the nature of the light omitting seal created by this blackout blind, windows must be closed while this blind is down. Opening a window behind the blind could cause a vacuum resulting in the fabric being sucked from the side channels and resulting in damage to the blind.
This blind is operated by remote control, and the motor and rechargeable battery are tucked within the barrel of the blind. As standard, we offer this blind with the solar panel charger which provides a trickle charge meaning it is a slightly easier means of ensuring the battery is fully charged. The alternative is to select the mains charger (one provided per order), which requires the front of the cassette to be removed to attach the charger (required around once every 6 months with standard use).
Available in either a White or Black hardware finish full technical specifications can be found in the Geeky Stuff section below.

Technical Specifications
Our Blackout cassette blinds are designed first and foremost to provide darkness in a room by creating a sealed unit in or around the window.
To fit this blind you will be required to drill multiple holes, not just into the masonry you’re fitting to, but into the headbox and side channels themselves as they don’t come pre-drilled. The reason for this is that you will need to ensure the entire blind sits squarely within a recess or against the wall, so you will need to decide where to specifically screw the blind to the wall.
The cassette blind is comprised of an aluminium headbox fascia in which the fabric on a barrel is held. Aluminium side channels run from top to bottom and are attached to the headbox. The fabric has fabric retaining pips attached to it and these pips are what hold the fabric in the side channels.
Important: When the blind is in operation the window must be shut. Failure to close the window when the fabric is anywhere but fully rolled up can cause the fabric to be pulled out of the side channels. This can damage the fabric or the side channel and the warranty will be voided. Do not operate this blind with an open window. If you install this blind on behalf of someone else, please inform them.
At the bottom of the fabric is the bottom bar that has a pile seal on the bottom of it. This helps to form a barrier against light at the bottom of the window when it sits on the bottom fixing strip.
The headbox measures 76.7mm high and 72.6mm deep.
The side channels measure 55.3mm wide and if recess fitted, the side channels are 29.5mm deep, and if face fitted, they are 25.2mm deep. Please note, recess-fit side channels cannot be used for face fitting, and vice-versa as they are different.
The bottom fixing strip is 25mm tall and 21mm deep and will match the chosen hardware colour. This L-shaped metal strip is there to allow the bottom bar to sit just in front of it, thus creating another barrier between the window and the room.
The hardware is available in white or black and the blind is operated by a motor that is held within the barrel of the blind and powered by an enclosed, rechargeable battery. The 7.4v DC battery-powered tubular motor comes with an inbuilt radio receiver. The tubular motor enables a 230v AC feed to power the motor which operates incredibly quietly. It has a noise level of 40dB and a nominal speed of 30rpm.
The remote control needs to be purchased separately and is not supplied with the blind. To protect the motor from overheating and to prolong the life of the product, the motor will cut out after more than four minutes of constant use to allow it to cool down.
The optional extra solar panel charger is made from amorphous silicon panels with a scratch-resistant high-strength aluminium frame. It measures 375mm x 50mm x 3.2mm and is for indoor use only.
The solar panel can be mounted to brackets positioned 342mm apart and has a cable that is 2.3m which connects to the battery. In full sunlight, the battery will be fully charged in 2 days, but a mains charger is supplied (1 per order) with all solar panels in case the battery needs faster charging or the area is particularly deprived of sunlight.

We expect our cassette blinds to provide darkness in your room for standard use. However, we are not able to guarantee absolute darkness due to differences in installation, location and light direction. Every care and attention has been made to engineer this type of blind to give maximum levels of darkness.

Obviously, there are a few exclusions:
✖ Damage caused by poor installation/not following fitting instructions (don’t worry, installation is easy, read this.)
✖ Misuse or Failing to maintain the blind
✖ General wear and tear and fading (these blinds are exposed to very intense UV rays)

✔ Manufacturing defects
✔ Fabric/slat colour fading within a year
✔ Mechanical malfunction
✔ 2 year warranty on battery and mains electric motors used in electric roller blinds

This blind features a fire-retardant fabric, providing peace of mind and safety to your home. Our fire retardant fabric is a high-quality material that will not catch fire when presented with a flame; instead, the area that is in contact with the flame will burn but it will self-extinguish once the source of heat has been removed.
This blind is made in the UK in one of DotcomBlinds’ UK factories. By purchasing a blind made right here in the UK you are helping to support the British manufacturing industry. Blinds made in the UK will typically have shorter lead times due to the fact they won’t need to be shipped internationally.
This blind is available on our Same Day Priority Dispatch Service, which is ideal for when you need a blind in a hurry. By selecting the Same Day Priority Dispatch option at checkout, your blind will jump to the front of our production queue, being made and dispatched that same day when ordered before 11am on weekdays (orders after 11 am or on weekends/bank holidays will be prioritised for the next working day). Please be aware that while most SDPDs are delivered the next working day, we do not guarantee next-day delivery.
This blind uses a remote control operation, the blind can be opened and closed by using the up and down buttons on the remote control or wall switch (both sold separately). Remote control operation is ideal for hard-to-reach windows and large windows.
This blind can be battery-powered, meaning that the motor is powered by a battery attached to the motor. Depending on use, you should get 6-12 months of charge out of your battery, and we supply a power cable for recharging the blind.
This blind can be solar-powered. When you choose the solar-powered variant, we supply a solar charging panel that attaches to your window and ‘trickle charges’ the battery that powers your blinds, ensuring they are always charged and ready for use.
This blind features a plain fabric with a solid colour. Plain fabrics are incredibly versatile and can easily be matched to the existing decor in your home or add a fresh new colour to your windows. Be sure to order FREE fabric samples to get a feel for the look and feel of the fabric in person before making a purchase.
This blind is available to order with a stylish headbox, covering the top of the blind and its mechanism. The use of a headbox can make your blind look neater and help to minimise light leakage over the top of the blind.
This blind features a blackout fabric, proving the light-blocking benefits you would expect from a blackout blind. This fabric will not allow exterior light to pass through it, helping to create a dark environment in your home, which is ideal for bedrooms and home cinemas. Please be aware a minimal amount of light may still leak into a room around the edges of the blind.
This blind features a thick thermal fabric, which will help provide additional insulation to your home’s windows, making your home more thermally efficient. In winter, these blinds will keep your home warmer by minimising heat loss through your windows, and in summer, they will keep your home cooler by minimising the amount of outside heat that enters your interiors.
