About Us

StonePly® is a fabricated stone panel wall system utilizing a composite panel made by laminating a natural stone layer to an aluminum honeycomb substrate with aviation epoxies. StonePly Honeycomb® is fabricated and then attached to the substrate with a series of aluminum extrusions. The three basic attachment methods for StonePly® are the Z-clip system, utilizing one piece Z-clip aluminum extrusions, the plate and screw system, utilizing concealed screw attachment and the adhesive attachment system, utilizing structural silicone. Two joint systems are available, the sealant joint, which uses backer rod and silicone, and the rain screen system which utilizes open, 'dry' joints.
