SUNPAL® MULTIWALL STANDING SEAM PANEL

SUNPAL® by Z Legacy International is an elite, highly engineered modular multiwall polycarbonate system designed for cutting-edge architectural roofing and vertical wall cladding. Seamlessly combining structural insulation with absolute weatherproofing, SUNPAL® utilizes an advanced standing seam joint mechanism. The panels are interlocked using specialized leak-proof click caps and connectors without any fastener penetration through the sheets, entirely eliminating structural leaks while accommodating continuous thermal expansion and contraction.

The core superpower of SUNPAL® lies in its internal multiwall cellular structure, which traps air pockets to deliver outstanding thermal insulation ($U\text{-value}$ efficiency). This substantially reduces energy costs by keeping interior climates cool in summer and warm in winter. Despite its lightweight architecture that lowers overall framing costs, SUNPAL® provides extreme structural rigidity and immense load-bearing capacity against heavy snow and high-velocity wind loads. Co-extruded with advanced UV protection to eliminate yellowing and degradation, SUNPAL® can be integrated with elegant internal LED lighting to create breathtaking translucent facades, making it the premier choice for modern sports stadiums, airport hubs, shopping malls, and sustainable commercial complexes.
