Architects please note that the current version of ASTM no longer makes reference to Type I Moisture Controlled units. Because the old Type 1 specification caused unnecessary job delays, Air Vol Block recommends referencing the most current version of ASTM C-90. Please call our sales office if you would like more information about this specification.
