Information on Strawboard requested

[Wooej]

I last came across strawboard back in the 60's when I made a garage roof
using it: 6' x 2' and 2" thick is all I remember. It was then given a cement rendering coat, followed by felt.

I now want to know what its weight is to calculate the loading of a flat roof which I have discovered is made using strawboard, but cannot find any details on the web.

Can anyone remember its weight / density or know where I can find out, please?

Perhaps someone can remember a trade name to follow up on?

Thank you. That name sounds familiar.

I've had a look: 380kg/m3 It sounds as if I may have a problem with what I propose.

Thanks anyway.
