How do metal wall panels adapt to high humidity in Manama towers?
Manama’s coastal towers—such as those in Bahrain Bay and Seef District—face persistent humidity levels above 70% year-round, presenting risks of corrosion, mold, and sealant degradation. PRANCE Design’s metal wall panels are engineered to thrive in these conditions through material selection and protective finishes.
Panels use 5005 and 5052 aluminum alloys, which offer excellent inherent corrosion resistance in saline environments. A multi-stage pretreatment—including chemical etching and conversion coatings—prepares the surface for factory-applied PVDF finishes. These finishes pass ASTMD 714 humidity chamber tests for over 3,000 hours with no blistering or loss of adhesion.
To prevent moisture entrapment, panel systems incorporate back-ventilated cavities that facilitate airflow and drying of any incidental moisture. Drainage channels at the panel base evacuate water quickly, and EPDM gaskets maintain sealing integrity despite swelling cycles caused by humidity.
Joint design features overlapping edges and concealed fasteners, eliminating exposed metal edges that can corrode over time. Periodic low-pressure rinsing and gasket inspections ensure panels continue to perform as seals age.
By selecting these humidity-tolerant aluminum wall panels, developers in Manama can extend facade lifespans, reduce maintenance costs, and preserve the appearance of high-rise buildings in Bahrain’s challenging coastal environment.
