Basic Info

This A1 grade fireproof high-density calcium silicate board is a professional building material developed for fireproof partitions and firewalls in commercial buildings. Made of high-purity siliceous-calcareous raw materials added with inorganic mineral fibers through high-temperature autoclaving process, it fully meets the EU EN 13501-1 A1 fireproof standard, and will not release toxic smoke or molten droplets at high temperatures. It has excellent impact resistance and structural stability, solving the industry pain points of traditional fireproof boards with insufficient strength and easy cracking. It can be widely used in crowded public buildings, combining fire safety and convenient installation.

Customer reviews

Michael O'Brien · Fire Safety Engineer
The A1-grade fire-resistant high-density calcium silicate boards exceeded our expectations in recent hospital corridor tests. When subjected to temperatures exceeding 1000°C for 120 minutes, the boards maintained structural integrity with zero flame spread or toxic smoke emission - crucial for healthcare evacuation routes. Their 850kg/m³ density provides exceptional impact resistance against gurneys and equipment. The non-combustible certification documentation was comprehensive and simplified our compliance process.

Product Description

Product features:

The core technical highlight lies in the patented high-temperature autoclaved foaming process, which ensures uniform and dense internal structure of the board, with bending strength far exceeding the industry average, and excellent crack resistance and long-term structural stability. Compared with traditional gypsum fireproof boards, this product has lower water absorption and is not easy to get damp and deform. At the same time, it supports multiple installation methods such as sawing, drilling and bonding, adapting to different construction scenarios. In addition, the surface of the board is flat and smooth, and can be directly painted and pasted for secondary processing without additional base treatment, which greatly shortens the construction period and provides a reliable fire safety solution for construction projects.

Product application:

It is mainly used for fireproof partitions, firewalls and fireproof ceilings of high-rise office buildings, commercial complexes, underground garages, rail transit stations and other crowded public buildings. It can also be used as fireproof isolation barriers for industrial plants and fireproof decorative plates inside ships. This product fully complies with domestic and EU building fire prevention codes, provides long-term fire safety guarantee for buildings, and reduces fire risks and losses.

Frequently Asked Questions (FAQ)

Q:How does A1-grade fireproof calcium silicate board enhance building safety?
A:A1-grade boards (non-combustible per EN13501-1) withstand 1000°C for 3 hours without toxic fumes. High-density versions (≥1.5g/cm³) combine structural strength with fire barriers for stairwells and ducts.
