Misk City Project, Riyadh: Premium Passive Fire Protection by KRON
Location: Riyadh, Kingdom of Saudi Arabia
Project Overview:
Misk City stands as one of the most ambitious and transformative urban development projects in the Kingdom of Saudi Arabia. Developed by the Mohammed bin Salman Foundation (Misk Foundation), this 3.4-square-kilometer development in Riyadh is designed to be the world’s first non-profit city. It serves as a dynamic hub for innovation, education, entrepreneurship, culture, and community development.
As a core component of Saudi Arabia’s Vision 2030 objectives, Misk City features a comprehensive masterplan that includes approximately 500 villas and townhouses, over 6,000 residential apartments, and world-class educational and commercial facilities. To safely accommodate its projected 18,000 residents, the city’s infrastructure requires state-of-the-art engineering, including rigorous passive fire protection to guarantee long-term safety and structural resilience.
High-Performance Firestop System Supply by KRON
To meet the strict fire safety and building code requirements of this visionary modern development, KRON supplied premium INCA Firestop System materials. As a leading supplier of certified firestop solutions in Saudi Arabia, KRON distributes INCA products that are rigorously tested and compliant with global certification standards, including UL, ASTM, FM, and Intertek approvals.
For the Misk City Project, KRON delivered the following specialized fire sealants and containment solutions:
Premium Firestop Products Supplied by KRON
To meet the structural and safety demands, we utilized a comprehensive suite of INCA fire protection products:
Elastomeric Fire Caulk Fire Sealant – INSS1186
INSS1186 is a premium water-based elastomeric firestop sealant engineered to seal dynamic joints and service penetrations. It is designed to maintain outstanding flexibility even after curing, making it an essential component in modern firestop systems.
Global Certifications: UL 2079, ULC S115, ASTM E1966, ASTM E2307
Packaging Options: 310 ml cartridge, sausage pack, 1-gallon pail, 5-gallon pail
Shelf Life: 2 years
Key Features:
- Water-based acrylic formulation for safe application.
- Excellent flexibility to accommodate dynamic joint movement.
- Low VOC, ensuring better indoor air quality.
- Halogen-, asbestos-, and solvent-free.
- Highly resistant to smoke, air, and water penetration.
- Easy application using a caulking gun, brush, roller, or spray equipment.
Ideal Applications:
- Dynamic wall and floor joints.
- Curtain wall joint sealing.
- Cable and pipe penetrations.
- Expansion joints.
2. SAS5000 – Smoke and Acoustic Sealant
Within a large, high-density mixed-use development like Misk City, occupant comfort and life safety are equally prioritized. The SAS5000 is a specialized sealing solution designed to aggressively restrict the passage of smoke and airborne sound through construction joints, perimeter gaps, and service penetrations.
This powerful sealant significantly enhances the building’s passive fire protection strategy by maintaining strict compartmentation, while also drastically improving the acoustic privacy between residential, educational, and commercial spaces.
Key Features:
- Premium smoke sealing performance to limit toxic gas migration during fire incidents.
- High-grade acoustic insulation properties.
- Remains flexible after curing to prevent cracking.
- Strong, reliable adhesion to standard construction substrates.
- Exceptionally durable for long-term building performance.
Ideal Applications:
- Gypsum board partition systems.
- Curtain wall and facade perimeter joints.
- Door and window perimeter sealing.
- Cable, mechanical, and service penetrations.
- Acoustic wall systems and expansion joints.
Misk City represents a monumental leap in urban development, seamlessly blending innovation, sustainability, and community engagement. To firmly support the project’s stringent safety frameworks, KRON successfully supplied heavily certified INCA firestop products, including the highly flexible INSS1186 Elastomeric Fire Caulk and the SAS5000 Smoke and Acoustic Sealant.
By integrating these advanced firestop systems, KRON ensures robust fire compartmentation, limits the spread of deadly smoke, accommodates structural movement, and greatly enhances acoustic performance. This ensures that Misk City not only meets but exceeds the highest international standards for life safety, structural durability, and overall building performance.
