14. Inclusion of Blindspace boxes
The size of the box will depend on the product you wish to conceal and the size of the window that you have. We recommend as large a box as practical for the best results. With a smaller box you may be limited by choice of materials you can use and also the hem bar may only just go inside the box. A larger box makes it easier for installation too. See size chart for more examples.
Roller Blinds For a window <2800mm wide and <3000 drop, we recommend W100x100 and W110x130 for some flexibility. The W110x130 can hold blinds for a window <4000mm wide and <3800mm drop.
Honeycomb Blind For a standard window up to 2200mm long a W110x130 will be sufficient, with W110x170 the drop can be 3800mm. If you have a gable window with the blind stacking on the slope we recommend W110x170 minimum or W100x200mm ideally. In all cases it is best to check with Blindspace what we would recommend to be sure.
For a rooflight it depends more on the type of system you are installing. The smallest systems, such as SHY ZIP, R110x130 can be used. It can hold blinds up to <1900mm wide and <2900mm long. In contrast, a TESS 660 from Guthrie Douglas that can do <2800 wide and <2700 length, can be installed without hembar box, concealing guide tracks and wires in side boxes. It requires the bigger R135x200 for headbox.
What is the maximum blind size?
See size charts above.
With our biggest standard box for windows, W210x270 a roller blind <6500 wide or <9700mm drop can be installed. With our biggest standard box for rooflights, R210x270 a ZIP blind <6400 wide or <19530mm long be installed.
If you find a bigger blind we will make a bigger Blindspace box for you.
What should be the overall recess size?
There are recommended measures on each of the drawings. For more detailed product information see also the installation instructions. Overall recess space should allow for 3mm tolerance around each side of the box for ease of installation.
For a window, with headbox only, the height of the headbox recess should be the height of the box, plus 3mm. The width of the recess should be the opening width plus 5mm on each side to allow for 2mm end cap and the 3mm for ease of installation.
For a window with headbox and side boxes, the height of the headbox recess should be the height of the box, plus 3mm. The width of the recess need to the opening size plus 50 mm for each side box, and the extra 3mm on each side, so a total of opening width plus 106 mm.
For a rooflight, the recess space depends on the type of system you are installing and the frame layout you go for. Depending on your situation you may use a full frame around the opening, a three-sided frame with no wires, or just a head box and hembar box but no side channels and use visible wires. The 3mm should be added on all box sides for ease of installation.
