I decided to replace the windows in my home with new construction Jeld-Wen aluminium clad windows due to the fact that the old windows were not properly installed and have alot of rot in the brick mold and window sills. I ordered the first window and want to know what is the best practice for trimming out the exterior. I have a Hardie Lap siding and will be installing the brickmolding around the window. All would be well except for the fact that there is no sill nose on these aluminium clad windows like there were on the traditional wood windows. On my existing window I have brick mold on top and the sides with the side brick mold running down to the sill nose. Is it normal practice to put brick mold on all four sides of the window and make a picture frame? I have attached links to the pictures of the old and new sill. Any help would be appreciated.

I'd recommend that you purchase and install sill nose under the windows. It may help to buzz a little angle off the sill nose where it touches the window so that it will fit up a little tighter with less of a gap.

Also, you'll want a drip cap over the top brickmould, but you probably already know that.
