Strength of polystyrene
Strength of polystyrene
(OP)
Hello
I am wanting to assess the strength of polystyrene and have obtained a data-sheet for the material we are going to use Attached).
I am not sure why there are two compressive strengths (@1% and @10%). I suspect it may be due to the compression of the material.
Can anyone educate me on the meaning of the values, please.
Regards

I believe the 10% number is typical for simple insulation. The 1% number is what you would use for structural fill. ie under full loading you would not want your insulation fill to compress and 10% of its thickness. Some manufacturers also list 5%.
There is some good information here http://www.geofoam.com/library.asp
