If you had to Tyvek or housewrap over ICF, how would you do it? I've talked to a few hardie siding contractors. A couple of them said it needs to have housewrap uner it. I don't think Tyvek over ICF is required, but if I have to put it up, I don't think it will hurt either.
So how could it be done? Stapled onto the foam?

If your ICFs have plastic bridging, I would use button tab nails driven into the bridging. This works very well for us. However, if you have metal bridging, you will have to use screws. |

We require it in CA. Usually use anything to hold it in place until the siding goes up, could be anything with a wide head such as a roofing nail into the foam.

I would think that the standard foam board nails with the plastic button heads and ring shanks would work just fine if driven into the plastic web pads. |

Arkie6,
Sorry, button tab is a common (colloquial) term of 'plastic cap' nails.

Why would you put house wrap on ICFs? |

Because some municipalities won't let you go without |

As I get older, I get more cautious. Tyvek is relatively inexpensive to purchase and easy to install. It adds an extra layer of insurance against air and water infiltration, and I'll take that trade off every time.

House wrap is not needed on ICF's.
In order to prove this, the ICF in question must have undergone Permeance Testing that was approved and accepted by the ICC in stating that house wrap and vapor barrier are not needed on the Wall System. If the ICF has completed this testing and it has been accepted, this documentation can be presented to your local building official. In order to obtain this information I would suggest asking the local Distributor or going directly to the manufacturer.

I agree with Buddy, many manufactures have this testing and could convince your BI that its not needed. I believe if you put the wrap on your going to start missing your fastening ties and have continual siding issues.
p.s. Chris J, your manufacture has this test also.

Unfortunately 1 out of 50 states uses a different code than the rest of the country.
What is ....
