[Greenbuilding] Advanced Framing/OVE in Midwest?

Sat Mar 3 08:53:53 CST 2007

We use panelized 2x6 16" o.c. construction one some of our homes and are
very pleased with the result, though we end up using more lumber than we'd
like. The timing of your post is interesting since I was researching OVE
this week to see if we couldn't reduce our material usage.  Has anyone else
actually built with advance framing techniques -- in particular 2x6 with 24"
o.c. in the Midwest?  I've run into polite resistance from my engineer,
green reviewers, architect, and carpenters because of concerns about
structural intergrity (specifically, what I understand to be a 90 MPH wind
rating requirement, which in turn requires a high cost sheathing that
offsets any OVE savings).  Only one company hasn't weighed in yet and that's
my panel company (who can give me the final material cost savings, if any).

I have to admit I fell into the trap of "nobody else is doing it that way
locally, so I don't know that I want to be the first and only," but then
that's a lot of what green building is!  I would just feel better about
pursuing this if I could talk to someone who had success in reality rather
than just a concept on paper.  Anyone?

What you are talking about is called "Advanced framing"  It is not that new,
but it is hard to get carpenters to change their ways.  

Advanced framing uses substantially less wood and provides substantially
more insulation.  

Here is a good link on advanced framing details:

hey all, 

two 'green' homes (to be leed cert) I've recently worked on did not have
trimmers for the most part, just king studs with sill and head for the
window ro. 
Headers that need to transfer load were hung on king studs with metal
brackets and or had unique framing assemblies where the header ran beyond
the ro on each side of the window.  turning the king studs around the window
to trimmers

I assumed this was a new 'standard' in material efficient framing and am a
little surprised to find you guys talking about trimmers. 

Is this just a personal preferance for most of you (want the nailing area
for trim) or is it off the wall to frame as I've described?

we've used grace's vycor for our window flashing.  we wrapped the sides and
bottom keeping vycor on framing and sheething under the house wrap, then
installed window, then a strip of vycor along the head of the window tucked
under the housewrap and covering the window flange.  housewrap goes over the
window flanges and gets taped.  if that's confusing at all just try to
picture the drainage plane and you'll get it.
sound good?
