Poretherm Roof Deck Info Needed 1950s

[NickVtx]

Has anyone run across a roof decking product referred to as 'Poretherm' and have any information on it? It is listed as roof decking on a set of plans I am reviewing from the mid-1950s and spans open web steel joists (SJ146) at 30 inches on center.

Don't know about that, but there is a clay block called Porotherm. Check this link:
