Measuring a roof window blind

Add exactly 7 cm to each side of the window recess width to obtain the correct blind width.

The blind height is the window recess height plus a minimum of 10 cm above the upper edge of the recess and a minimum of 8 cm below the lower edge of the recess.

If the required space is not available (10 cm above or 8 cm below the window recess), please contact Customer Service.
