Questions & Answers


I can't see a size guide for these conversion kits. Which particular conversion kit would I require to upgrade a GGL1 window (1990-ish) please?

It didn't quite fit. I read the instructions 3 times and had to redo the installation twice, with some tweaking to the old parts too, but in the end I got it to work. Let's hope it keeps the rain out...

I bought this when replacing the glazing unit in a GGL-1 skylight. Does exactly what it is supposed to. I'd give it 5 stars if the pictogram instructions were a bit clearer. I had to look up articles on the internet to make sense of the process. Skylight looks great once done.

As warned, the replacement unit was much heavier than the original but installation was straightforward.
