Guest guest Posted September 10, 2010 Report Share Posted September 10, 2010 Hi, I got a bid from a contractor to do some work on a building my mom owns, and the contractor is suggesting replacing the current rotten siding with Hardy " stucco " style sheet product. Is this a good product or is it problematic, and if so, why? Any recommendations on better product for exterior siding? This is a little retail strip mall, we don't live there, no one lives there, but people do work there, my mom doesn't have the money to waste trying to make this an extremely healthy building but I also don't want to install highly toxic materials either, a reasonable balance between health/safety & cost...also, I don't want to install a really cheap product that won't hold up and then have to replace it a few years later. Thanks for any suggestions. Thanks, Sue V. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 10, 2010 Report Share Posted September 10, 2010 I like Hardy board, as it does not support mold growth. However, I do recall some members of this group saying that chemical off-gassing was a problem.

Guest guest Posted September 10, 2010 Report Share Posted September 10, 2010 Connie, thanks for the feedback, maybe the chemical offgassing would be tolerable in an exterior usage?? especially i haven't heard that anyone working there is chemically sensitive... sue > >I like Hardy board, as it does not support mold growth.

Guest guest Posted September 10, 2010 Report Share Posted September 10, 2010 Sue, Hardieplank is a composite of concrete and wood fibers. It can absorb up to 30% its weight in water so as long as it is installed properly and not under any water flows, it should be fine. If there is water splash onto the planks near grade, the planks should be back primed with an acceptable sealant. Also, cut ends are supposed to be sealed. And there is supposed to be a 2-inch clearance to any roofing. To keep water out of joints, it's a good idea to slip a short piece of roof paper (or other water tight material) at any joints. (Go to the comapny web site " Installation Guide. " ) If roof water flows down the siding from valley or roof-wall intersection, the material will peel and may delaminate.

Guest guest Posted September 10, 2010 Report Share Posted September 10, 2010 Jeff, thanks, I will make sure the contractor is going to do it correctly or not at all. sue v. > >Sue, > >Hardieplank is a composite of concrete and wood fibers.

Guest guest Posted September 10, 2010 Report Share Posted September 10, 2010 I highly recommend going to the info section of building science.com. The article " Mind The Gap " comes to mind, and " Brick, Stucco, Housewrap and Building Paper " . The Hardy can get soggy & you need a gap behind it so it can dry & not wick into the building. I went with painted plywood, Tyvekover it, then 1/2 " furring & then donated metal roofing as the outside layer. > > Hi, > > I got a bid from a contractor to do some work on a building my mom owns, > and the contractor is suggesting replacing the current rotten siding > with Hardy " stucco " style sheet product.

Guest guest Posted September 10, 2010 Report Share Posted September 10, 2010 I wouldn't tolerate it indoors, esp w/ windows closed but outside I'd be OK I think. > > Connie, > > thanks for the feedback, maybe the chemical offgassing would be > tolerable in an exterior usage?? especially i haven't heard that anyone > working there is chemically sensitive... > > sue > > > > >I like Hardy board, as it does not support mold growth.

Guest guest Posted September 10, 2010 Report Share Posted September 10, 2010 Jeff May identified the most important aspect of Hardy siding - proper installation. As an exterior veneer, this product looks great and does not have the same problems that previously were identified with the products that had OSB backing. Hardy board does appear to be more forgiving that many other products. Proper drain planes are necessary for brick and other veneers and are not unique to Hardy. This product is low maintenance, at least on my house.
