Hi All,
I am new to this so here goes. I have looked in the archives already for some answers but have not found any pertaing to my questions. So if I have missed it, sorry for reposting.
Here is the situation. House built in 1974, Chicago area. Has Masonite siding with Celetex sheeting and R-7 batt insulation. On the south facing wall the siding is completely shot and needs to be replaced. The size of the siding is 9 1/2″ width 8 1/2″ reveal. I would like to strip the siding down to the studs and rebuild using HardiPlank siding. The idea is to use 1/2″ exterior grade plywood, also some type of house wrap either Tyvek or Tyvar ( village code) and HardiPlank for the siding. The questions are as follows.
1. HardiPlank comes in a width of 12″ or 9 1/4″. Should I use 12″ width and cut down to 9 1/2″ or use 9 1/4″ with only 3/4″ overlap? And yes I know the ideal solution would be to reside the complete house.
2. Any idea’s on which would work best Tyvek or Typar? What is the main difference between the two?
3. Any suggestions on best method to upgrade the insulation in the walls working from the outside?
Thanks in advance for all comments?

hi softball gonz:
I would suggest using the substrate as suggested by Hardi Plank. Their website I believe will have the information (if not, I can look it up in my manual for you). Even for residences, I usually spec Tyvek, but truthfully.... owners may change to something different on job. ;)
Different size siding: A possible solution to the siding sizes varying.... If possible remove siding from area to be redone with Hardi-Plank and use it to fill areas on a different elevation. I'm not sure if this will work with the amount area you are doing. However, having 1/4" siding smaller on one elevation shouldn't be too noticable. Just a suggestion.

You should be able to use the 12 as it is. Just overlap 3 1/2.
First of all, I use both Hardi and Certainteed. I prefer Certainteed....I believe it is a slightly better product.
Second, you're wrong on the widths. Both Hardi and Certainteed come in 6 1/4" (for 5" exposure), 8 1/4" (for 7" exposure) and wider....your options are greater than you realize.
The sizes I mentioned are the ones I use regularly and I tend to avoid the wider planks because, IMO, when you start getting real wide, the siding starts looking cheap, or what you might see on a 400 unit apt. bldg.
To get a specific exposure, you can rip the planks (gang them up and use a good carbide blade designed for F/C) or increase the laps.
Now on your specific project you seem to be locked into duplicating the exposure on the Masonite. I think if you do some layout on paper or look at some F/C sided homes in your area, you'll find that the narrow exposures will have more curb appeal.
I prefer Typar because it 1; has a longer exposure to the elements life and 2; it isn't as blinding in the sun as that white stuff and 3; the Typar is less ugly IMO while the work is in progress.
