   do any SIP manufacturers use Neopor?
Thanks!

Yes, Insulspan has done Neopor from our Blissfield Michigan plant.  

Thanks, wheath!

Any one else???

PM'ed

I don't know what stage they are in for developing neopor SIPS but this was posted on the web.

Does anyone have performance data on the benifits of neopor of the differences between it and plain EPS? The press release at the url above is pretty vague

Is there a significant price difference between Neopor and regular EPS?

Does anyone know the expected density and R-value per inch of Neopor? I've heard a number of values for regular EPS but the ones I believe are the test results per ASTM C578. The following is what I've seen for EPS tested (per this standard) at 75 degrees F: 1.0 lb density EPS R-value 3.85/inch 1.5 lb density EPS R-value 4.17/inch 2.0 lb density EPS R-value 4.35/inch (testing at colder temps obviously gives higher numbers) I would like to know how Neopor compares.

www.neopor.basf.com??? u check there?

Jonathan, Thanks for the link. They have a chart at http://www.plasticsportal.net/wa/plasticsEU~en_GB/portal/show/content/products/foams/neopor_neu/neopor_product_sub2 Based on the chart the best insulation advantage for Neopor is at 15kg/m3 (roughly 1 pcf). That would equate to an R-value of 4.37 (versus 3.85 for regular EPS). As the foam density increases above 1pcf the advantage of Neopor decreases. They claim an insulation advantage of 20% but the chart seems to indicate 13.5% at best.

Have they also done new testing with the neopor foam?

I’ll have to look at our prices for both, but I would assume the XPS would be a better deal, being it's a R-5 per inch. Lamit can do both but we really just don’t market them. I can say we have sold more XPS SIPs than Neopor SIPs.

Informal only. 
Chris, you know the scenario it's the chicken and the egg.   We spend 100's of thousands of $ on testing and then something new comes along that shows potential but needs to be reviewed in order to meet our code listing.  We aren't in a big rush.
  
What potential SIP customers need to take into account is that R-value is only one part of what SIP's are about and it can be said not even the most important part.  Air infiltration reduction being the pair of aces in the hole.

Agreed ^^^^ Seems like something always needs/could be tested Cost wise I still say a EPS SIP is the way to go

wheath;

yes I am familiar with the costs of testing, I am not yet sold on the upsides to neopor.

FWIW, a few days ago, before I knew of this thread, I asked for some background substantiating data on Neopor's R values vs. standard EPS.   All I have received so far is a statement that BASF uses "data points of ten years collected in Europe and certified by multiple official organization throughout Europe."  This is essentially what their sales literature says too.   I have not received or found any of this data as of yet, and I would like to, as the product's other attributes seem appealing.
