SIPs and Rigid polyurethane foam properties wanted

SIPs and Rigid polyurethane foam properties wanted

SIPs and Rigid polyurethane foam properties wanted

(OP)
I am using a Structural Insulated Panel as a ceiling and am wanting to check my design.  I am going to treat the SIP as a stress-panel and transform the PUR core to OSB for my design checks but I am having trouble tracking down the parameters that I need for my calculation.

I am trying to find out the properties of PUR, the material that is used for the core of Structural Insulated panels.  I have tracked down the compressive, tensile and flexural strengths of PUR in a Canadian Code but I also need shear and elasticity.

Would anyone be able to point me to where I may find this information, please?  I will also be needing similar information for dense polystyrene.

What sort of glue would be used to bond the core to OSB.  I think it is a polyurethane adhesive that is painted on and cured.

Any information would be appreciated.

Regards

Their are a couple of very reputable SIP mfgs out there and many who are not (No testing done)

Google EPS out of Iowa - I think they know what they are doing...

RE: SIPs and Rigid polyurethane foam properties wanted

You should really not go with an ISP provider who has not rested his product in a reputable lab environment.  I would not calculate how these things work.  There is too much that can go wrong.  Go with published rtested results for a specific product.

I, too, have had to change providers because the information I needed was not available.

The problem with going to the SIP provider, they do not have this information and many have not tested their products.

I have just found this site which has all the information.
