In your opinion, a vermiculite gypsum based wet mix spray - proposed to protect concrete and steel structure from fire - should be included in IEQ c4.2 for a project in Italy pursuing LEED 2009 Core and Shell certification?
If yes, under which standard (Green Seal Standard or SCAQMD Rule) should the product be tested?
This kind of fire retardant coating (quite similar to a spray applied plaster) appears to me quite different from any intumescent painting.
