I’m about ready to install 8 inch clear cedar siding stained with semi- transparent over foam sheathing.
1. House wrap or 15 lb felt underneath?
2. How about stainless finish head screws for attaching? reason- no chance of hammer marks, pullouts, easy adjustment later if needed.
3. What clear finish as a top coat. The semi transparent color is perfect.
THANKS

dan,
1. felt
2.Your choice, if you like the look and time doesn't matter, why not? Could use brass for another twist as an interesting look as well, though stainless would hold up longer. I do think that nails are less likely to introduce water than screws, be careful.
3. I don't have a good recommendation of my own, but have seen a lot of advice on this, check the archives, possibly some posts still in the current system too.
*Dan: can't place my hands on the info right now, but I know I've read recently where siding is not to be put directly over foam, use furring strips over the foam. As advised above, check the arch's. Another consideration is to not make a double vapor barrier, otherwise the wood in between is going to sweat.
*Are you talking about a thin layer of foam over traditional framing or "foam" poured block with "nailing"strips
*I think cedar siding has been discussed at length in past posts - I vaguely remember discussions of Cedar Breather, back priming, and other aspects. Do a search, you should get enough to keep you occupied for the evening.

This is 1 inch foam sheathing over standard wall construction. I have looked further and seen the archives about this subject. I am convinced about furring it out 1/4 inch. Not sure about the felt and screws yet.
THANKS A lot of information on this site.

Dan,
I'm with Mad Dog on the felt. I've pulled apart 100+ year old houses with felt and the sheathing behind is in great shape. The siding, incidentally, was in great shape as well.
I'd use nails instead of screws because screws would be a pain in the neck and I think would be ugly. The last bajillion feet of cedar siding I installed was nailed with ring shank siding nails painted brown to blend with the stain. Maze I think was the brand. Overlap the boards about an inch and place the nail about 1-1/4" above the bottom. Make sure you hit the furring strips if you use them (DO use them). After the first hundred nails or so, you won't be whacking the siding that much -- start in the back so you can make most of your mistakes then.
Also, make sure and take the time to strike level lines all the way around the house so your siding matches up at the last corner. Rent a level transit for a day and shoot in the tops of the windows. Make this the bottom of a course of siding. Hold a ten foot 1x4 next to those windows and transfer a mark to it. Then measure up that stick 8" (or whatever the siding width is) and scribe a line accross. If oyur overlap is 1", mark lines every 7" above and below this line. These are the tops of your siding courses.
Go around the house to all the corners, windows, doors and other interuptions and line up the top of window line (or really any other line for that matter -- as long as it's the same one all the way around) with the transit and tack the story pole to the house. matk all of the tops of siding and move on. After all the marks are in place, snap those lines all the way around the house. (Maybe you should put those furring strips up first though).
Definately back prime (seal) this stuff before you install it (especially if you use furring strips) and make sure you have some sort of kick ass insect netting at the bottom. Seal the end cuts too befor installation, but regardless, it'll probably shrink over time. Cut the long pieces a little long and snap them into place to allow for shrinkage.
I'm not sure as to what's best to seal it with, but keep in mind, you only get to seal the back once, so use the heavy duty stuff (whatever that is -- polyurethane?).
Watch out for that thumb!
Dan
*Ditto on the furring strips, IMO.Jeff
*If it were me I would...Use the furring strips, if installed over foam.Use 15# felt, and not house wrap.Backprime. I just tore out a bunch of 1x10 cedar that wasn't backprimed. Who ever installed it was wasting the customers money.Nails, not screws. These nails go in really easy, so there should be no need to wack them hard, and dimple your cedar.
