Question
Hi and thanks in advance.

We're doing some extensive remodeling and replacing some windows with different sizes.

We ordered and took delivery of some aluminum windows that have a nailing flange set about 1.5" in from the outer face of the window.

Since the trim and hardiplank are, at most, 3/4" deep, it seems this is going to leave the window face about 3/4" proud of the side of the house. Is that right? Am I leaving out some layers here?

Thanks again.

Answer
Hi Mike, your Hardi trim is usually 1" thick and depending on the window manufacturer, sometimes the window sticks out beyond the trim and sometimes the trims is flush with the window and sometimes the window is in a bit.  In your case with a 1.5" shoulder your window face will stick out beyond the trim.  This should not pose a problem unless you don't like the look.  You can always shim out your trim to be flush with the window frame or use a 1.5" 2x6 or 2x4 trim instead.  Follow manufacturers recommendations for caulking.   I hope this information helps please feel free to write again regarding this or other matters, sincerely bruce e johnson.. bejohnsonconsulting.com
