For high-performance envelopes, we prioritize stones with low water absorption and high density. The top choices include:

• Granite: The gold standard for durability, offering superior resistance to acid rain and abrasion.
• Travertine: Preferred for its unique texture; we use specialized resins to fill voids and enhance structural integrity.
• Limestone: Excellent for consistent color, but requires high-quality protective coatings in coastal environments.

FOWALL ensures all stone panels are cut to a minimum thickness of 30mm for safety in commercial applications.
