Blindspace – Blind Box Profiles

Designed to Disappear

Blindspace blind box profiles to conceal any type of blind, in any type of window. The unique Blindspace design provides millimetre precision and a better finished aesthetic than traditional building methods whilst saving you time in both design and installation.  

The hidden space inside the wall or ceiling can be prepared for manual or electric blinds and accessed for blind installation when construction work is completed. From the smallest windows to massive doors and skylights, our solutions are made to make any blind disappear. The alternative is surface-mounted products with visible side channels, cables or cords.

Multiple Configurations

Blinds are concealed in any of the following ways using Blindspace boxes.

  • Concealed inside the wall.
  • Concealed inside the ceiling, with the blind gap towards the window or towards the room.

RAL Colour Matching

All Blindspace blind box profiles can be primed and painted on site, alternatively we can offer a colour matching service  to any RAL reference.  Either the entire box or just the hinged cover plate can be colour matched.  In most instances if the box is being fully recessed, it will only be the hinged cover plate that would need to be colour matched.  Both options are available when you specify the product above.  For the majority of colours a powder coating process is used, however for some special colours that are not available in powder coat, a durable wet spray paint will be applied.  The Standard profiles are supplied in RAL 9003 30% gloss.

Buy Blindspace blind box profiles online using our product configurator  – or call for assistance and advice.

Our prices are for a fully made to measure specification cut to your exact specification.  If you want to save on the BlindSpace cut to size charge then order in 600cm lengths.  All our prices include end caps as standard.

Fitting Tips:

Blinds can be concealed inside the wall or inside the ceiling, with the blind gap towards the window or towards the room. The most common configuration in windows and doors, is to use a headbox only, however in rooms where blackout blinds may be required, Blindspace side boxes and bottom boxes are also frequently used.

As a general rule, blinds should be installed as close to the window as possible to minimize gaps on the sides of the blind. This increase privacy, reduce light coming in and warm air circulating to the room. With Blindspace side boxes, gaps can be eliminated and 100% blackout can be achieved.

It is important to allow for protruding door and window handles when configuring the blind gap close to the window.

Please note:  Due to the size and weight of these products we can only offer subsidised and not free shipping.  Shipping costs are detailed at checkout.

Sizes and Technical Drawings

The size of the Blindspace box required depends on the type and size of the blinds to be fitted. The larger the glazing area and blind, the more space is needed to hide the blinds. As a general rule, a bigger box also allows for more options and easier installation.

The largest length of a single blind fitted within a 100×100 box is 2.5m. The largest length of a single blind fitted within a 110×130 box is 3.5m. Multiple blinds can be fitted side by side.

Due to the increased stack on cellular blinds (when the blinds are fully raised), for longer drops we recommend the 110×130 box profile.  This should ensure the hembar remains concealed.

Standard Blindspace S Series boxes are available in 100×100 mm and 110×130 mm. For single roller blinds in floor-to-ceiling glazing, we recommend S110x130, however S100x100 is the most popular option. S Series is available in 6m lengths or cut to specification.

Available in two sizes and four flange options.

Whilst we will endeavour to fulfil our delivery promises once the goods leave our warehouse we do rely on 3rd parties to fulfil their obligations.  We therefore recommend that a fitter isn’t booked until the goods are safely in your hands and have been checked for damage and any missing items.  We cannot be held responsible for any fitter cancellations.

We hope that you are delighted with your purchase.  We do recommend paint sample pots, wallpaper and fabric swatches are ordered prior to ordering the full sized items.  We can also send out ring samples, colour toggles or off cuts of curtain poles / tracks to ensure the colour is right before you commit to order.  Please email to request a sample.  Please note made to order / measure / cut to size products cannot be returned or exchanged unless faulty.  Please also note that we cannot accept returns on any paint orders as they are mixed to order.

For any standard products not listed above, in the event that you would like to return your goods we accept returns within 30 days of delivery.

There is an £20 collection charge to return curtain pole or curtain track orders. We appreciate this is a lot of money but this is what our couriers charge us. Curtain poles and tracks are classified as ‘oversized’ items and so they incur a premium for handling long parcels.

If you would like to return curtain pole accessories or curtain track spare parts these can be returned by Royal Mail or a carrier of your choice.  Please return smaller items to: The Home Of Interiors, 19 Brookley Road, Brockenhurst, Hampshire, SO42 7RR.

To return and obtain a refund (excluding delivery costs) please email us at or give us a call us on 01590 615775. We will then contact you to organise the collection / return. Failure to notify us may result in no refund or an additional cost to forward your returned item/s to the correct address.

Any products you return will be at your own cost and the goods must be in the same condition which they were received.  The goods must be in their original packaging.  The goods are your responsibility until they reach us so please make sure any returned items are very well packaged to avoid damage while in transit. Please ensure the returns reference, which will have been emailed to you, is clearly marked on the outside of the parcel.  We recommend you use the outer packaging the goods were delivered in.

If on receipt of the goods we inspect them and conclude that they are not in the same condition they were sent out in we will not be able to provide a refund. We will notify you if this is the case.

The refund, minus the original delivery charge and minus the collection charge, is usually actioned within a week of the items being returned but it can take up to 30 days. The refund will be made back to the account that the original purchase was made from.
