Is veneer plaster considered an air seal?
I run a remodeling company in Littleton, MA that has become very focused on builiding envelope efficiency and durability. We (myself, project develper, production manager, and project supervisors) are working on standard specifications for air sealing and as we were discussing interior air sealing, one of the project supervisors asked if sealing the perimeter of the wallboard at inside corners was really necessary if we were properly sealing the framing joints behind the wallboard and skimcoat plastering all those inside corner joints. His reasoning was that if it is necesarry to seal these joints then why aren't we sealing other seams in the field of the wall. This got us all wondering if veneer plaster was considered an air seal or if we've been missing a step in good air-sealing practices.
