IndiaWILLSTRONG® SHP
Stone Honeycomb Panel
WILLSTRONG® Stone Honeycomb Panel bonds natural stone veneer to lightweight aluminum honeycomb, retaining elegance and reducing weight by up to 70% versus solid stone.
Engineered for high-rise facades, luxury interiors, and retrofits, SHP offers impact resistance, flatness, and easy installation without overloading structures.
The aluminum honeycomb core, directly laminated behind the stone veneer, ensures outstanding panel flatness and shock absorption—critical for large-format natural stone facades.
With A2 fire-rated safety and superior dimensional stability, SHP prevents cracking and delamination, making it a reliable choice for demanding architectural projects.
