Velux roof window - retrofit a solar opening

KnownMaynard

Hi All,

Looking to add a solar opening so I went to the Velux website and found the kit KSX 100K WW...Only it says not compatible with windows CK02, which is the one we have (GGL CK02). The other kit they sell is for "pre-2014" windows, which ours again is not. So I am struggling to find which one I would need, has anyone fitted one afterwards on this window type, or know why it says it's not compatible. I am inclined to believe them as they are the manufacturer, but when I look on other sites stocking them, the don't always mention compatibility (Jewson's for example). I did email the Velux sales email address but no response. Been going down a bit of a rabbit hole searching online to try to find an answer.

Any insights appreciated, thanks in advance.

It's half term in Fife from today, may explain why e-mail reply is taking time.

Every window 78cm and under (height) is listed as incompatible. Given that's only 5 sizes I'd be a bit surprised if there was something specific for them, and I can't find anything from a quick search. Definitely worth confirming with Velux but think there's a good chance you'll be disappointed unfortunately!

If that is the case and you're desperate, swapping out velux windows for the same size is often straightforward. Looks like buying the window with the solar opener integrated is only a few hundred pounds more than the conversion kit, and maybe you can make some of that back by selling the existing window?
