How does everyone interpret this excerpt from the Nachi Standards of Practice?
First it says we need to describe the type of insulation, then it says we are not required to identify the composition. I’m confused. Isn’t type and composition the same thing?
Thanks in advance.
3.9. Attic, Insulation & Ventilation
II. The inspector shall describe:
A . the type of insulation observed;
IV. The inspector is NOT required to:
E. identify the composition
Type: Is a particular kind.
Composition: Is somethings ingredient.
Hope this helps.
OK yes that helps thanks.
Such as:
Type: Vermiculite
Composition: Possible ACM (Asbestos Containing Material), Vermiculite is a hydrous phyllosilicate mineral. It undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and the effect is routinely produced in commercial furnaces. Vermiculite is formed by weathering or hydrothermal alteration of biotite or phlogopite.[2]](Vermiculite - Wikipedia)
That would be correct. :mrgreen:
Duh! Of course it is. Why else would I post it? :blank:
Type would be batt, loose fill,etc. IMHO
Frank, so do you only identity loose fill or batt, or do you try to identify fiberglass, rockwool,vermiculite etc?
I’m saying that the definition of “type” is loose fill, batt, spray foam, etc.
I agree.
Describing it would identify it as fiberglass, cellulose, vermiculite, etc.

Great! I get it now thanks so much. Thank you for the chart Christopher that really helps also. I’m going to print it and keep it as a reference.
Not all batts are fiberglass as the chart seems to infer. Cotton batts for one.
I only posted the chart to show what “type” meant in this situation.
Yes, understood. Nice chart.
I only identify batt, blown in, or lack there of as I see some with nothing. The exception is vermiculite, I do say something like what Jeff posted.
