Genuine VELUX® Energy Cellular Blinds

Measuring for inside a Recess

First ensure that the recess your blind is going into is not obstructed in any way so the blind can hang freely. Look out for protruding tiles, pipes, skirting boards etc.

Measure at the top, middle and bottom of the window recess and note down the smallest measurements to the nearest millimetre, this is the recess size.

We will make your blind smaller to fit into the recess.

There is no need for you to make any adjustments we do this in production this is called recess size

Your blind will arrive slightly smaller than the recess size, it will then hang freely within the recess at the correct size.

If you want to make your own allowances order as ‘exact’ which is explained below.

Measuring for Bay Window

Determine the depth of the blinds you are mounting and use this for the width of your cardboard: Contact us for Blind depths.

Cut two pieces of cardboard (depth determined from 1 above) wide by 30cm (12") long.
Important: If spacer blocks or extension brackets will be used for extra clearance on outside mounts, add the amount of extra clearance to the width dimension of the cardboard before measuring.

Place the strips in the left angle first, and bring them together until the front corners of the cardboard meet. Mark points "A" and "B".

Repeat this step for the right side angle, marking points "C" and "D".

Measure between points "B" and "C" to obtain the width measurement of the center blind.

Measure from point "A" outward to the desired width to obtain the width measurement of the left blind.

Measure from point "D" outward to the desired width to obtain the width measurement of the right blind.

Deduct about 5mm from each of your measurements to allow for clearance, and order Exact
