The GGL-4 windows I have were installed in 1987.The blind kit I purchased from Velux did not contain upper frame mounts so I had to source these locally from a blind supplier at additional cost.The option to include these mounts for older frames should be made clearer on the website.Disappointed.

Thank you for your feedback. We’re sorry to hear that the installation was more complicated than expected and that the additional mounting components required for your older windows were not clearly identified during the ordering process. We understand your disappointment, especially after having to source the upper frame mounts separately and incur extra costs. Feedback like yours is valuable, and we will share your comments with the relevant teams to help improve the clarity of product information and compatibility guidance for older window generations.
