Sheeting on exterior walls
What is a good exterior sheeting to use during framing. I don't really like OSB. I have heard of a product, I believe is called Built-rite??????(not sure) it is supposed to "breathe". Any suggestions.
Thanks

I have not seen anything called build-right. I am using 1/2" exterior grade plywood, like you I would like the greater strength for the wall.

I agree with Peters. You can't go wrong with 1/2" ply. sheathing. Any R value lost is more than made up by added structural strength (if attached correctly). I will admit that sometimes I will use OSB as wall fill with plywood on the corners, but I also like to cut in diagonal bracing on exterior walls even with solid sheathing.

IMO added structural strength cannot make up for lost R value - R value lost, is heat or cooloing that will be lost every year on increased bills. I assume OSB is strong enough, therefore the only noticible difference will be a structure that transfers heat more readily.

Built rite is a low density fiber board that has virtually no structural value. If you use built rite you will need to put in steel diagnal bracing between the built rite and the studs. You should also put plywood or osb in the corners. The only advantage to built rite is a little more r value but I would at other material for that purpose.
What do you have against osb? The manufacurers claim it is stronger than plywood. I'm not sure I believe that but it certainly has enough structural integrity for wall sheeting.

Lots of us "Old School" people had a hard time converting to OSB, but so far I haven't herd of a house falling down because it was used. Our house is built using it, I drug my feet a bit but as allways the cost factor entered the picture. Plywood is costly now, but if no body used OSB and all insisted on plywood what would it cost with that much less competition and lots more demand? Just my ramblings. Frank.

Just to bring up an old subject (we talked extensively on this before) We have a new subdivision going up out here. Once again! Since we talked last on this subject I have been watching all new construction around here. Most low end houses  ($250K) are built with the osb on the corners and around the windows and the insulation type board on the rest of the walls. OSB is on all the roofs!
The higher end houses all seem to have osb 100% around and on top of the houses with only a few with Plywood on the roofs.
Was thinking that maybe this is a locational building practice because I see many of you scauffing at osb.
I would not think twice about osb, infact I am leaning more toward osb than any plywood lately especially if it is 16" ioc. I have osb on the roof of my garage I built 2 summers ago. Plywood on my vacation homes roof I built in 2001. I have 2 small waves in the house roof and the garages is perfect. If I would of gone with a thicker ply for the house I would not of had that problem I think although the waves are very small and hard to notice, I still DO notice it. They are between 2 of the roof trusses.
IMO Whatever you use Ply or OSB just buy a quality sheet and dont cheap out on the thickness and you should be happy with either. Like I said before I do think it is a "regional thing" on what is used because around here in Southern Wis. osb is used almost exclusively.

We have 7/8" Gold Edge Seal OSB subfloors and had a sink overflow in the laundry room. The cut edges of the OSB have swelled up some and telegraphed through the linoleum. I would only use OSB in an area where there is absolutely no way for it to get wet.

Here is SE Michigan we use OSB almost exclusively---roofs, walls and floors. Plywood is used on some commercial builds where fire break/resistance is required like on a townhouse or apartment. Around hear OSB costs the same as plywood. My neighbor's new $450K house uses a fairly new OSB product on the floors that is literally waterproof. He left it uncovered (no roof) all through the winter and spring and there was not even a joint that swelled---not even where the screws are. Made a believer out of me.

I know HardiPlank makes 4X8 sheets for exterior use, does anyone know if they make something to be used as an underlayment? It would seem to be bulletproof with the possible exception of the weight factor.
