Hello everyone. I'm new to this building thing. I decided to build a 16'x12' shed in the back of my property. I bought some 36"x36" windows to install from Home Depot. I put them in and nailed them using the nailing fins. I was thinking of using Hardie on the outside. I've seen some people trim the windows, and then use the siding butt up to the trim, and I've also seen people put the siding up, and then attach the trim on top of the siding. I was thinking of putting the trim on first, and then the siding. The thing I've come up against is, the windows stick out 1.25" away from the exterior, and Hardie trim is 0.75". I've been looking online at a lot of 'how to install windows new construction' videos but the only thing I can find is, maybe I bought the wrong type of window for my application? Maybe I didn't need ones with nailing fins? I've attached an image of what I am referring to. Maybe I just need to install the siding first, and then the trim on top of that, and it will even itself out. Thanks.
