I’ve yet to fit my blind. Need to sand down and re varnish the old wooden frame first (unfortunately weather not on my side at the mo!) my velux is a pre 2013 model, so needed help to find the serial number, the customer service lady was an absolute star, and guided me through the process of flipping the window (for which I was always under the impression it couldn’t be done!!!) it can and does...... so I’ve now got a clean top half to my roof window and also got rid of nearly 15 years of cobwebs, gross
