Document record
The file is a guide specification dated October 2024 for the PAC-4000 RV reveal wall system, supplied as a Word document. It is written as Section 07 42 43 and covers an MCM wall panel assembly with an installation system and accessories. The title line reads PAC-4000 DRV – Reveal System, and the product list names PAC-4000 RV.
The system description calls for a barrier system, sealed at all panel joints, intersections, dissimilar material abutments and cutouts to form a weathertight barrier. It requires provision for thermal expansion and contraction, and design to positive and negative windload pressures under the latest adopted local building code. General performance must be shown by testing performed by a qualified agency.
The reference list adds NFPA 285, the standard fire test method for exterior wall assemblies containing combustible components, to the ASTM and AAMA standards. Those include ASTM E84 surface burning, E283 air leakage, E330 structural performance, E331 water penetration, E903 solar reflectance, and AAMA 2605 for organic coatings. Definitions for MCM, LEED and ISO 9001:2015 are included, and the product data requirements ask for the manufacturer’s datasheet, installation guidelines and recycled content literature for LEED MR Credits 4.1 and 4.2.
