How does ACP cladding’s water infiltration resistance differ from brick cladding?

Aluminum composite panel (ACP) cladding employs a rainscreen system that excels in preventing water infiltration compared to traditional brick cladding. ACP panels attach to an air-gap sub-frame, creating a ventilated cavity behind the facade that promotes drainage and drying of incidental moisture. Joints between panels are sealed with neoprene gaskets or silicone, ensuring continuous protection against wind-driven rain. In contrast, brick cladding relies on mortar joints and weep holes for water control. Over time, mortar can crack, erode, or become clogged, leading to water penetration and potential substrate damage. Brick ties and anchors may corrode, compromising system integrity. ACP’s non-porous aluminum skins do not absorb moisture, and factory-applied finishes resist staining and corrosion. Additionally, ACP systems incorporate integrated flashing at sill and head details to divert water away from openings. For aluminum ceiling soffits or canopy edges, ACP panels maintain a consistent barrier without efflorescence or mortar drip marks common with brick. Overall, ACP rainscreen assemblies deliver more reliable water infiltration resistance and require less ongoing maintenance than brick facades.
