My plan is to frame the opening around 1.5 larger than the window. Then make a 1.5 insert template to router cut both ceiling and roof, Then uninstall the template to install trimlok and glass. Is that similar to what you did? I guess yours passed the water test...
Hi Chris..... I'm not sure I'm understanding your question. I can go out and look at the trailer in the morning (and maybe look at the CAD)... but are you asking about how I made the opening for the window? Just want to make sure I understand what you're asking so I don't pass on wrong info. I did make the window a bit larger than the opening, but you have to base your window size once you figure out what gasket you're using. So the window actually sits slightly proud of the opening within the gasket.
Regarding the "water test".... I did have a few areas where water was making its way in. I had gotten some butyl caulk (which, from my understanding, is really the only caulk that will work with the EDPM gasket material).... and kind of worked the caulk into the seam between the acrylic and gasket. I did this in a few spots and it seems to have resolved the issue. My original plan was to lay a bead of the butyl caulk in the gasket before I inserted the window.... which may have been a good idea, however that stuff is so gooey and sticky it's really tough to work with and probably would have made a frustrating mess.
EDIT: Attached is a picture of the gasket I used. You'll notice where the glass is placed kind of overlaps the space where the gasket fits onto the vehicle, thus allowing the glass to be actually a bit larger than the opening in the vehicle. When you're driving down the highway you don't want the gasket rolling and the glass rolling into the opening and kind of collapsing..... making the glass larger than the opening (hopefully) would prevent this.
