Sinhai’s polycarbonate facade solutions offer lightweight, durable, and visually versatile options for architectural exteriors. Available in solid, embossed, or honeycomb multiwall structures (4–16mm), these panels provide weather resistance, thermal insulation, and design flexibility. Solid panels ensure high clarity for modern glass-like facades, while embossed variants add texture and privacy. Honeycomb hollow panels reduce heat transfer (U-values as low as 1.8 W/(m²·K)) and support large spans, ideal for commercial buildings and transit hubs.
