Blindspace – Blind Box Profiles (New 2022 profile)

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.

Standard S Series

Blindspace S Series is new for 2022. It features the patented Blindspace Safety Hinge that secures the cover in place and can be installed in any direction, allowing for side boxes to hide blind side channels or guide wires. Popular in floor-to-ceiling windows and sliding doors, S Series can be installed to future-proof buildings to have the option for later installation of concealed blinds.

Features and Benefits

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.  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.

Measuring Guide

  1. Refer to the frame design options and skim coat flange options below to confirm your requirement.
  2. Download the technical drawing for your installation type from the ‘Sizes and Technical Drawings’ tab.
  3. Download the Measuring guide below.
  4. Download the fitting instructions below for additional guidance.

Note.  We supply all our blind boxes with end caps, so the blind box size requested will include the endcaps.  As a result the internal dimensions when you fit the blind will be 6mm smaller than the box length specified.  We recommend boxes are installed and final internal dimensions are taken before blinds are ordered.

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 130×130 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 130×130 box profile.  This should ensure the hembar remains concealed.

Standard Blindspace S Series boxes are available in 100×100 mm and 130×130 mm. For single roller blinds in floor-to-ceiling glazing, we recommend S130x130, however S100x100 is the most popular option.

Available in two sizes and three flange options.



Our online configurator will automatically specify the correct side channels for the top box size selected.
