insulrock 1

[bjb]

I am checking a building from 1965, and the drawings call for a roof deck consisting of 3" of insulrock. Has anyone heard of this stuff before? Is it similar to poured in place gypsum? I don't see in the drawings where they call out for form boards or bulb tees.

Insulrock was a roof deck panel system by Flintkote Products that was made of a portland cement slurry and excelsior (a curled wood fiber), formed into planks and mounted in a system of "T" subpurlins. The whole system was similar to Tectum.

This link should get you an old brochure...

I think Insulrock was sold to another company and there's a chance it can still be purchased; however, Tectum should suffice if you need replacement panels.
