I just installed 3 replacement windows. 53" x 41' double hung Pella from
I've trimmed back the siding to 3" from the edge of the new windows. I now
plan on cutting some pine to 2 7/8" wide, priming it and framing around the
outside of the windows.
1 - should the trim be 3" all the way around? The original window had a
thick wooden sill with no trim on the bottom. the new Pella windows have an
aluminum sill, very thin sill sloping to the outside. looks like I should
put some kind of trim under it.
2 - Should the vertical trim extend 3" above and below the window and the
horizontal trim will be the same width as the window?
Or go the other way with the horizontal trim extending 3" beyond the sides
and the vertical trim is the same height as the window???
I'm leaning towards ripping a 2x4 to about 2" x 1.5" with the top angled to
match the slope of the sill. it will fit under the windows sill and be
thicker than the side and top trim. It will extend 3" out past the window on
each side. this will add alittle "meat" to the thin window sill. the pine
top trim will also extend to the same width as the bottom sill and the
vertical trim will fit in between. (the same height as the windows.
This seems to match some of the wide variety of trims I've noticed on houses
while driving around...
Any suggestions, opinions on the "proper" way to frame the outside of these
windows would be greatly appreciated.. I live in New England and I have to
get the outside sealed up before the really cold weather sets in..
