This is the skylite I added to our Triilium
Also a new vent to replace the leaking inadequate aluminum one (and that annoying chain) as well as beefing up the warped FRP with a .25 in ABS panel.
This is very cool - I was just dreaming about a skylight in our trillium - and my ceiling is sagging a bit near the skylight so I need to reinforce it. I thought of doing something similar to modify the entire centre ceiling ridge. Can you share some of your materials and construction info? THanks so much!
I was beginning to believe no one liked it (although I loved it...) I am in Ontario so maybe I`ll run into you someday.
The impetus for doing it was pretty much the problem you describe: saggy ceiling as well as a leaky vent. Something you can`t tell from these pics is that there is a pc of ACM (aluminum bonded to plastic) sheet that slides over the opening on the inside so you aren`t cooked to death in the morning when the sun comes. I will have to take more pics when I get it back out of storage. I`ll post what I can find if it helps you move ahead with it. Basically, there is a .25" Polycarbonate window with a scratch resistant coating. I am hoping it doesn`t yellow too bad over time. Used butyl rubber to seal to the .25" ABS sheet, then used bonded the sheet to the roof with automotive urethane adhesive. (the type they use for autobody work) The screws were stainless # 8`s i think. Acorn nuts to the inside w/ washers and created a groove with more .25" ABS 1" and 2" strips so I had a channel for the ASM to run in....this would probably seem much easier to understand if I had pics..OK I found a few. There was quite a bit of "dry fitting" before I started gluing. I generally work alone but I had to break down when it came to getting someone to hold the nuts on the inside while I was on the roof tightening them. I used self sealing stainless washers on the outside. Dumped copious amounts of water on it (from the roof of the house) to see if it leaked and so far so good...
