Everyone put on your thinking caps.


Any feed back is appreciated.

Subject: 9 foot walls, single story. Hurricane clips tying truss's to inside panel skins.

1.      If a sips wall were installed without the outside skin touching the subfloor, what would the wall have a tendency to do in cold weather, assuming the interior is heated?


2.      Next, assume the outside skin is not on the subfloor, and the bottom plate, is not resting on the "Groove Plate", what would the wall have a tendency to do in cold weather, assuming that the interior is heated.


What would the suggested fix be? 


Thanks for your imput!!

Correct me if I'm wrong, but in order for a STRUCTURAL Insulated Panel to be structural, does it not require that both skins rest firmly on some type of support so that the loading on it is transferred evenly to the structure below? I know this is the case with all the panels I have used, and in every manual I have read.
If you have been told that this is not the case, then I suggest that you confirm this with your supplier, and their engineers.

Both skins of the SIP should be on solid foundation or flooring to prevent shearing.
