Roof Blind Size
You will normally find your window size listed on the inside top edge of your window. For more information, please view our measuring guide.
If you are struggling to find it, we have built a handy lookup table where you can measure the visible glass size and convert it back to a window code. View glass size lookup table.
Top tip: If you have an older Velux window and your window size is prefixed by a 0, don’t worry about this. They are the same. For example, there is no difference between GGL-4 and GGL-04.
Bead Depth
When ordering your blind, you will need to provide your window's bead depth so we can provide you with the right size bracket which your blind clips on to. To measure place a credit card across the corner of your window frame, and measure from the glass to your credit card.
Window Type
You will normally find your window size listed on the inside top edge of your window. For more information, please view our measuring guide.
If you are struggling to find it, simply select GGL (which is a universal code) and then ensure you select the correct Size.
What is a T-post?
T-posts are a recommended support for Tier on Tier shutters. It is a horizontal bar which the top tier sits on, ensuring that the shutter does not sag. As this is a recommended part of the shutter, any Tier on Tier shutters that are purchased without a T-post will not be covered by our guarantee.

When the motorisation upgrade is selected, this option determines the position of the motor and charging point for easy access.
Material Join
Due to the fabric width selected for your Roman blind, a symmetrical join will be required on either side. Rest assured, we take great care to ensure if there are patterns in your chosen fabric that these are precisely aligned for a seamless finish.
Due to the size of your blind and the dimensions of the fabric, we will need to make a join in the material. We will make the join along the width of the blind as close to the top of the roller blind as we possibly can. In some cases the join will be hidden especially if the blind is never fully closed.
External Battery
For narrower blinds, an external battery pack is required and will be included with your order. It fits neatly behind the headrail, maintaining a seamless, uncluttered look.
Handle Position
To ensure a perfect fit, we'll customise a section of the shutter frame to accommodate your window handle opening. Please inform us of the handle's position in relation to the rest of the window in millimetres.
Measuring for this is a straightforward process. Ensure that your handle is in the fully open position, then measure from the edge of the glass to the centre of the handle. If your handle is located at the bottom of the window, always measure from the left side of the glass to the centre of the handle. However, if the handle is positioned on either the left or right side, measure from the bottom of the glass to the centre of the handle.

We take the safety and well-being of children very seriously. That's why all of our blinds are supplied with a child safety device, which ensures cords and chains are safely secured to the wall, preventing the risk of strangulation. Each blind is manufactured with a maximum chain length of one metre, keeping it out of reach of small children. If you require a chain longer than one metre, please contact us when you have placed your order. Conditions will still apply in accordance with child safety regulations.
We are proud members of the British Blinds and Shutters Association (BBSA). The BBSA is a leading trade association that represents manufacturers and suppliers of blinds and shutters. As members of the BBSA, we are committed to supplying blinds that are child-safe, and all of our products undergo rigorous testing to ensure they comply with the guidelines outlined in the British and European Safety Standard (BS EN 13120:2009+A1:2014).
