** NOTE TO SPECIFIER ** Continuous insulation wall panels are intended to be used continuous over framing members and to be relatively free of significant thermal bridging. Coordinate with other trades to minimize the penetration of thermal conductors through the wall system. The incorporation of Weather Resistant Barriers (air, vapor and moisture) is a critical element of a continuous insulation wall assembly. It is strongly recommended that the Architect perform dew point calculations of the assembly at the location of each project using local code requirements and ASHRAE Standards. The calculations should be used to verify the dew point of the assembly and to determine the locations of the weather resistant barrier(s) as required.
