Can the stone curtain wall system accommodate thermal expansion and contraction without cracking?

Yes. Thermal management is built into the core of FOWALL's Dry Hanging System. By decoupling the stone panels from the primary building structure, we manage expansion through:

• Expansion Joints: Precision-engineered gaps between panels (typically 6mm-10mm) filled with high-elasticity silicone sealant.
• Slotted Support Rails: The aluminum or stainless steel sub-frames feature slotted holes that allow for millimetric movement during extreme temperature fluctuations.
• Material Compatibility: We select stones with low thermal expansion coefficients (like high-density Granite) for projects in extreme climates.
