   See if Pella can supply "Masonry Clips". Andersen and Marvin both make these. Basically you remove the nail flanges and replace them with clips that will extend into the interior of the home and can be nailed to the framing. You can then stucco or caulk in the exterior.

   I have some new Pella casement windows I am going to install in our kitchen. They come with a nailing flange all around. The exterior of the house is stucco, and all the other old windows have a real sill. What is the best way of installing these new windows?

   1. I could make the opening bigger than specified and install a real redwood sill and snap off the nailing flange on the bottom. Any water would hit the sill (eventually) and run outside.

   or

   2. Nail it in place with all the flanges in place in the appropriate size hole, then install a "fake" sill (the window wouldn't actually sit on the sill. The sill would be attached to the sheathing) and stucco all around it. Then, I could caulk between the sill and the bottom the the window.

   Any suggestions???

   *Foam it in. I have in the past had jobs with the exterior material being right over the flanges of aluminum windows and just removed the glass and then collapsed the aluminum frame and with the flanges removed from the new windows shimmed and foamed them in to place. It was amazing to see just how well the foam held the windows.These windows were not getting hard weather because of the size of the roof overhang so I wasn’t concerned about water as much as just sealing around the windows which I did with the foam and a high quality caulking. I wouldn’t worry too much if I did have to have a window to the weather side because today there are a number of really high quality caulks available that would easily do the job of weather sealing too and never crack or allow a leak.

   I have been installing windows using flat straps from stimpson. All the stores carry them and they basically do the same thing as the factory clips. Fasten straps to the side of the jamb, shim, level & plumb, then bend straps over inside of framing and fasten. Fill with foam of course.
