I am in the design phase of my house and my prospective builder is leaning towards superior walls for the basement and sips for main floor walls. He has built single story Habitat homes with sips and has built some framed homes with superior walls for basement and spray in insulation. He is starting construction of his own home which will probably be sips on superior wall basement. Any experiences out there with this combination? I am in Iowa so our temperature/moisture range is huge.
If I want to use brick as siding does that make for any other considerations? I assume I would need some kind of concrete footing for the brick to stand upon. Thanks, Steve

| Any "real" brick needs a footer / supporting ledge , for any type construction |

crash;
I dont think ties can be attached just to OSB, Ithink the need solid wood stud attachment |

| Ok, good questions to bring up to my builder. Thanks. So I guess without studs you can't attach shelves, railings etc to the sips either (?). |

no not at all, but certain coverings, sidings, brick veneers are specific in the code books in that they require a solid attachment, I just dont think the OSB qualifies in some cases.
In LA after Katrina, FEMA found that brick veneers pulled away from structures due to improper attachments and let the flood waters in |

Superior wallls can be constructed with brick ledges at any desired location. This is standard procedure for the company.
We have done one home that is constructed with SIPS over superior walls with brick veneer. Everything worked just fine.
If you are worried about the holding power of brick ties in OSB, then specify that the ties be attached with screws in lieu of 1" roofing nails, which is what most bricklayers use.
By the way, just how in the heck is a brick veneer wall going to keep flood waters out of a house? Aside from the fact that bricks are like little sponges when it comes to water, what about doors, windows, crawlspace vents, etc. FEMA's logic in that statement evades me.

Thanks for the info. You mentioned brick 'veneer'. Can you describe that for me and what is your impression of it? Or maybe it was just standard mortered brick. (I am looking for a non-maintenance siding like brick) It does kind of concern me attaching anything to OSB without a stud behind it. Could it weaken over time in our extreme weather?
We are on high ground but living in Iowa floods are on my mind these days. If a stick built house was flooded I assume you could take off the interior and exterior coverings, strip out the insulation and maybe dry it out or replace frames that are bad. But with a sip could you even salvage the house?
Also another sip related question (sorry I am a newbie here) relates to the glue. Does anyone have any concerns that a a wall held together just by glue (albiet put together under great pressure) will have trouble in extreme climates after many years. Thanks! |

brick veneer is standard brick, typically SIP adhesive is waterproof, but the OSB when saturated for a length of time would start to swell, flake and could loose it's structural integrity and would be prone to mold growth............., cement fiber or steel SIPs would fair better in flood conditions and are both FEMA approved for below base flood elevation use, in using either of those products you could strip out flooring, trim and damaged drywall, but exterior structural walls would not be compromised
There have been accelerated aging tests done on steel SIPs and they have proven to have a life span in excess of 300 years |

attached is the Test reprt from 2004, it explains the aging cycles
you will see the results show that the OSB panels started to fall apart immediately
and
the steel SIPs were unaffected after 15 cycles |
