The PAC‑4000 DRV Field-Assembled System delivers design freedom with practical advantages for rainscreen construction. Built from 4mm composite panels with a robust thermoset phenolic core and aluminum skins, this system provides long-term performance with minimal maintenance. Designed for cavity wall applications, the DRV system uses a hybrid approach to create a cavity wall (rainscreen) where the panel is sealed into position but allows moisture to exit the system via weep holes placed within the perimeter extrusions. Floating splines within the moldings allow for standard (1/2-in.) and variable (up to 12-in.) joint widths, giving architects unmatched creative control over spacing, depth, and rhythm.
For the field-assembled systems, PAC-4000 material is delivered directly to the jobsite along with prefinished trim moldings and accessories. These materials are then cut to size on-site by installing contractors, which shaves weeks off the project timeline (compared to similar systems, which are first shipped to fabricators). The direct-to-jobsite process also reduces shipping costs by taking up less space than factory-fabricated systems. Standard carpentry tools can be used to cut and install PAC-4000 material, further adding to the ease of installation.
Optimized for fast-paced projects, the DRV system offers quick lead times and field flexibility while maintaining the aesthetics of a high-end façade. It meets or exceeds ASTM E283, E330, and E331 standards and is approved under ICC‑ESR‑1015 and FL14436.4.
Durability is built in—PAC‑4000 DRV resists fire, water, and impact while arriving on-site protected with a strippable film that safeguards the panel finish during transport and installation. With a broad palette of long-lasting Kynar® 500 and anodized color options, the PAC‑4000 DRV system blends bold visual impact with practical performance. Whether you’re designing for corporate campuses, cultural institutions, or mixed-use developments, this system brings bold form and reliable function to every build.
