How much heat transfer are you going to get through a 2x6?

a 2x6 has an R Value of about 7, so you lose a little bit, but I don't see how it could be $1,000 a year.

In a straight run a 40' wall, with no windows will take 21 studs at 24" O.C. and at 16" O.C. it will be 31, so 10 more studs, 15" of a reduction in R value is not a big deal.

I seriously doubt there would be much noticable difference in energy costs between a house framed 24" O.C. Versus 16" O.C.

But that is what we do in America. We rob peter to pay paul. A couple people start crying about the disappearing forest, so we figure out how to make it out of steel. Then they cry about how expensive it is and how dangerous it is to work in a foundry, then we etc...you get the point.

We have more trees in the United States today than we did before the beginning of the industrial revolution.

Yet the tree huggers are always crying about something.

I know a guy who was saying we need to get rid of all of the C02, because we have 50% more C02 today than we did in the past and we are going to run out of oxygen, I asked him how the trees would survive without C02.

Whats the Best R value for a window? 2 or 3. By having jacks you are basically extending the size of the window,since the are such a heat loss, but with a better R value. I think someone said a stud is R 7. Six of one....Your not saving much buy not having jacks.

My bad, your right about that.

I guess it really depends on the jurisdiction. Around here it is not a problem if it is in the IRC and if it is in the Simpson book. And is just considered another standard and really not alternative anymore.

There are windows made in Canada with fiberglass frames that have an R-factor of 14. I havent been at this site long enough to provide the link. It wont allow me too.

In Florida if the plans show jacks, they must be used.

If the project is not built as drawn, we get tagged and have to either build it as drawn or revise the drawings.

The plans are not just plans they establish a record for how the project is supposed to be built.

The building inspectors do not allow us to make changes in the field, without getting the plans revised and getting approval from the building department.

I have had some plans come to me for commercial buildouts that showed 24" O.C. framing, but we changed to 16" O.C., we can do that in the field, but if the plans show 16" O.C., even though code allows us to use 24" O.C. it has to be shown as a revision.

On one commercial remodel, the guy I hired to do the plans made a mistake in assuming the walls around the entire bathroom were existing firewalls, they were not required all around the bathroom, just on 1 wall in the corridoor, but since he showed them as being firewalls, we had to build them, or go through a revision, we didn't have time to wait on a revision, so we built the firewalls, because they were on the plans.

I now go over the plans very thoroughly when working with Architects and draftsmen to show them how I want it drawn.

Wow, didnt know that. What is the R on the glass?? Cuz that was kinda what i was talkin about, there is usually more sq. inches of glass than sash & frame. And do you know the approx cost of these windows? Ithink you should be able to type out the link manually, right?

i framed up a house like this last year, it didnt have structural sheathing only rigid foam, when the siders came they flipped because there was nothing to nail the cape cod trim to. 2 days later we recieved a work order from the builder to install backing at all the ro's and corners so they would have something to nail to

on the same note i still find the idea of no jack stud questionable the king will be more free to move and with a door thats not something you want

Try DOW SIS (Structural Insulated Sheathing). It combines OSB and Foam. Great to work with for added wall stability

Kgmz

Did the walls have let in bracing? I hope so.

With this type of framing, the sheathing and nailing of it is even more important than with a normal wall.

Around here I have never seen a advanced framed building that does not have plywood or OSB sheathing. And they did put foam on top of the sheathing.

BuriedHammer

24" oc framing + foam??? Yikes!!!

Prove that please.

I have a book called "A Natural History of Trees,Of Eastern and Central North America", By Donlad Culross Peattie
Not a very up to date book, but an interesting read about the virgin White Pine in Colonial times, and how it was nearly wiped out by the british empire for it's diversity. At one point it was illegal for colonists to harvest the tree for there own use, because it was "property" of the Empire.
At time of print (1948) the author states that white pine was in the neighborhood of 14 billion bd ft in the U.S. And 8.7 billion in Canada.
Whether that is more than before the industrial rev i don't know.
Interesting book though.

I will dig up the information but where the stat comes from is all of the trees that are planted for lumber, paper, restoration projects etc.

Kind of difficult to believe
since this country was practically
solidly forested from the Atlantic
seaboard well west of the Mississippi.
If one looks at a current satellite
photograph, it would be difficult to
determine where all of these "extra"
trees are concealed.
Perhaps under all of that farmland
and pavement?

More as in quantity, they may have less canopy.
