Benefits of Petrarch Composite Stone Panels

Petrarch Composite Stone Panels offer the enduring beauty of natural stone with the performance and practicality that today’s façades demand. For over 50 years, Petrarch Composite Stone Panels have helped architects bring creative visions to life with unmatched performance, aesthetic variety, and sustainable value. Whether you’re specifying for high-traffic environments, sustainability goals, or complex detailing, Petrarch delivers long-term value without compromising on aesthetics.

Petrarch’s composite stone aesthetic has inspired architects for decades, offering the beauty of stone with modern performance:

• Over 1,500 earthen and natural tones produced to date
• 5 composite stone finishes: smooth, smooth matte, riven smooth, riven matte, honed (extra lead time)
• Through-color material with natural, uniform weathering
• Color matching and customized finishes

For long-lasting, low-maintenance façades in high-traffic areas, Petrarch composite stone panels deliver uncompromising performance

• 50-year industry-leading warranty
• Best-in-class moisture absorption: 0.15% after 24 hours of submersion
• (93x less than fiber cement, 32–46x less than GFRC/UHPC)
• Best-in-class Impact and flexural strength
• No picture framing, delamination, or efflorescence
• Natural and uniform weathering vs blotchy and uneven fading
• Non-porous surface and easy to remove graffiti/clean
• NFPA 285 compliant and Class A fire-rated

Petrarch Panels are up to 2–3x lighter * than traditional materials like GFRC, UHPC, and Terracotta. They also offer much more flexibility on-site and in application.

• Install on a radius in the field
• Use on soffits, and even at grade
• Cantilevered returns up to 6 inches – great for window returns
• Easy field fabrication and cutting, and no need to seal edges
• High-quality factory fabrication available

Sustainability is at the core of every Petrarch panel, helping reduce your project’s carbon footprint while ensuring long-lasting value.

• Minimum 70% natural composite stone material
• Long product life span reduces the need for replacement
• Can be upcycled and reused
• Cut-to-size options reduce or eliminate field cuts and jobsite waste
• Shipped using a minimum amount of packaging material, primarily recycled cardboard and wood for a palletized base (2” x 4” wood studs and OSB plywood panels)

If you’re targeting LEED or other green building certifications, Petrarch is a value-driven solution that supports your goals.

Unlike VE options that cut corners, Petrarch offers real value:

• Competitive pricing—face-fixed or concealed
• Lower site damages (no need to over-order as much material)
• Lightweight panels reduce shipping and subframe costs

Think value upgrade, not value engineering.

Petrarch is as versatile as it is durable, making it a smart choice for a wide range of project types. Whether you’re working on new builds or refurbishments, its impact resistance, weather resilience, and timeless stone finish make it ideal for:

• Education – Schools, colleges, and university buildings that need tough, long-lasting façades
• Healthcare – Hospitals and clinics that demand hygiene, durability, and visual appeal
• Transport Hubs – Train stations, airports, and bus terminals exposed to heavy footfall and the elements
• Commercial – Office buildings, retail parks, and mixed-use developments that balance style with performance
• Residential – Apartments and housing developments that require low maintenance and long-term value
• Civic & Community Buildings – Libraries, museums, and cultural centers where design and durability go hand in hand

No matter the sector, Petrarch delivers a refined natural look without the compromises that come with traditional stone.

Looking for a low-maintenance cladding that combines timeless stone aesthetics with proven durability and a low carbon footprint? Petrarch delivers.
