| I tried to look into steel framed sips, but one thing I am having a hard time understanding is about the possibility of heat/cold and moisture transfer. I have sent email to two companies, one whose steel framing is actually exposed on the outside of the EPS, questioning heat and moisture transfer but never received answers. Can someone please tell me if there is in fact heat/cold transfer or moisture transfer with these steel framed sips?
Thanks - Bob |

Anything product that has a steel framing member all the way thru the wall will have thermal transfer.
If it has studs in it, then it is not a true SIP, those products are prefabricated wall sections. I have seen several companies calling themselves SIPs when in fact they are not.
A SIP has skin / a core / skin, hence the name - Structural Insulated Panel.
We have been building for 12 years with true steel SIPs, they are structural in nature and do not depend on any studs or splines for additional support.
The only points susceptible to thermal transfer is the base, top cap and window / door framing both on a steel and wood OSB panel. However, this is not a problem in the southern US, thermal imaging cameras have shown a thin pencil line of transfer at those points.
On the other hand, If you are building in cold climates you can still successfully use steel SIPs by using thermally broken, bases, caps & channels.
I have seen steel SIPs used as far north as Calgary. I have not seen moisture transfer on any southern construction and would not expect it in the north if properly done.
Properly done is the key word, as many in the industry know there was a problem with wood SIPs used in Alaska where the roof joints were not sealed correctly and over time the condensation was trapped in the panel and eventually rotted them. |

| with a fluke thermal probe we took some readings from the sun side and shade side of a sip panel hose in biloxi a few weeks ago. mind you it was walls only and the sun-side was 132, the shade was 89. |
