NC-v4.1 EQc2:Low-Emitting Materials

Insulation calculation by surface area

Hi all,

The guide says that at least 75% of all insulation, by cost or surface area, meets the VOC emissions evaluation. Logically, if I decide to calculate my insulation by surface area, I must not consider the thickness. So hypothetically speaking, if I have a wall with three different insulation boards of 1" (total of 3") and I have an other wall with one insulation board of 3"... then does my second wall with 3" insulation only count for 25%?

Whereas by density/volume/performance, it would've counted for 50% and the other three panels for 16.666% each...

I just want to be sure I do my estimation right.

Thank you

Marie-Christine, the little digging I did regarding testing procedures (STANDARD METHOD FOR THE TESTING AND EVALUATION OF VOLATILE ORGANIC CHEMICAL EMISSIONS FROM INDOOR SOURCES USING ENVIRONMENTAL CHAMBERS VERSION 1.2 ) indicates test samples have to have  standardized surface areas. So I would say that the Credit requirement is correct.
