We are involved in offering Calcium Silicate Blocks. The raw materials for calcium silicate bricks include lime mixed with quartz, crushed flint or crushed siliceous rock together with mineral colorants. The materials are mixed and left until the lime is completely hydrated, the mixture is then pressed into molds and cured in an autoclave for two or three hours to speed the chemical hardening.

Unmatched Fire Safety and Thermal Stability

Hysil Calcium Silicate Blocks have earned Class A1 fire safety (EN 13501-1), making them completely non-combustible. Their high thermal stability ensures reliable insulation up to 1000C, guarding against extreme heat exposure in industrial environments. These blocks reduce the risk of fire spread and maintain integrity under high-temperature conditions, making them ideal for safe applications in construction and industrial settings.

Superior Durability and Versatile Applications

With cold crushing and compressive strengths of at least 1 MPa, Hysil blocks withstand significant pressure and wear, ensuring a long lifespan. The blocks are available in both square and tapered edge profiles to meet different installation and design requirements. Their versatility makes them suitable for a wide range of uses, from industrial furnaces to soundproof partitions.

Efficient Packaging and Storage

Each batch of Hysil blocks is shrink-wrapped and palletized for secure transportation and convenient handling. Thanks to their low moisture content and robust packaging, they maintain an indefinite shelf life when stored in dry environments. This durability and long storage capability make them a practical choice for large-scale projects.

FAQs of Hysil - Calcium Silicate Blocks:

Q: How do Hysil Calcium Silicate Blocks provide fire safety in building applications?

A: Hysil blocks are classified as Class A1 under EN 13501-1, meaning they are completely non-combustible and offer the highest level of fire resistance. They do not contribute to fire spread, making them extremely effective at enhancing safety in both industrial and construction environments.

Q: What is the recommended process for installing Hysil Calcium Silicate Blocks?

A: Installation of Hysil blocks involves proper alignment of either the square or tapered edges depending on the application, with the use of suitable adhesives or mechanical fixings for secure placement. Ensure the surface is clean and dry before installation for optimal bonding and longevity.

Q: When should I choose Hysil blocks for my project?

A: Hysil Calcium Silicate Blocks are best selected when high thermal stability, non-combustibility, and strong sound absorption are required. They are ideal for insulating high-temperature industrial equipment, fire-resistant partitions, and environments demanding robust durability.

Q: Where can I source genuine Hysil blocks in India?

A: You can obtain Hysil Calcium Silicate Blocks through authorized distributors, exporters, manufacturers, service providers, or suppliers throughout India. Ensure you purchase from trusted channels for authentic products meeting the specified standards.

Q: What are the primary benefits of using Hysil Calcium Silicate Blocks?

A: The major advantages include fire safety, stable performance at high temperatures, resistance to moisture and shrinkage, sound absorption capabilities, and long-term durability. These properties contribute to safer, quieter, and more reliable installations.

Q: How should Hysil Calcium Silicate Blocks be stored to maintain product quality?

A: For maximum shelf life and performance, store the blocks in a dry area while keeping them within their shrink-wrapped, palletized packaging. Proper storage ensures they remain undamaged and ready for use, regardless of how long they are stored.
