I am converting a deck to an enclosed sun room. The original railing had glass panels. I sized the deck panel width myself so I could place standard commercial door glass as panels. Basically, a frame of 2 by 6, with a small strip on front and back holding the glass in. Worked great. However, I am now trying to use the same glass panels as lower windows in the sun room. I removed the glass and used a pvc trim to form the exterior support the glass would rest against. Caulked the inside with silicone and placed the glass. I then applied pvc trim on inside to secure glass, and trimmed the window. Looked great, but leaks like crazy when rain and wind hits it. I did the same thing with a vinyl clad "replacement window" from Lowes for the upper windows; I placed a replacement window into the framed hole, screwed it at sides, caulked, and am leaking.... What did I do wrong. Should I have used a glazing compound instead. How would a professional approach this project. I know that an ideal solution is a window for new construction with fins... Can I fix this with same windows. I am happy to remove them, but cant afford to toss these windows out and use 'new construction' windows... How can one waterproof a window like this that is set into a wood frame (hole in the wall)...

I am looking to convert an existing “bow “ window into a sliding patio door. The bow window is a what they call a “walk around window “ (floor to header ) with an opening approximately 80 “ x 113 “ . Because of the size , the window ( arc) at its greatest distance protrudes about 20 inches from what would be the “inside” wall if it were a straight window. So in a sense , if I were to use the existing opening, I would lose the square footage that the walk around portion of the window creates. The current window is in the front of my home under a covered “raised “concrete porch. The step down to the porch is approximately 6 inches from the inside and then 96 inches to the top of the covered porch. In addition, the face of the house is brick . I want to “bump the doors out “ approximately 24-30 inches. On the install, I plan on using a lime stone slab (4” thick x 8” wide x length) as a base for the patio door and the side frame build out . This will be placed directly on the concrete porch in a cement “pool “ to level. I don’t want to lose any width on the window / door , so I would extend the frame approximately 6 inches on each side ( the “new length “ would then be about 125 inches) I would then come back 90 degrees and attach to the house going through the brick and into the vertical portion of the current header . Would then build a “ new header” approximately 24-30 inches out from the current one . Any exposed wood would be wrapped in window installation tape and then covered with exterior vinyl siding. I am looking for comments, suggestions , or criticisms. Thanks in advance
