Engineered architectural systems designed to meet international standards for fire safety, acoustics, and structural longevity.
An in-depth technical analysis of why calcium silicate boards are replacing traditional gypsum and cement boards in critical fire safety systems.
Manufactured via a high-pressure hydrothermal reaction of siliceous materials (quartz dust, diatomaceous earth) and calcareous materials (lime, cement) reinforced with organic fibers. This creates a highly stable, crystalline matrix known as Tobermorite, which does not degrade under high thermal exposure.
As a non-combustible material classified under EN 13501-1 Class A1 and ASTM E136, our calcium silicate boards exhibit zero flame spread and zero smoke contribution. Under exposure to temperatures exceeding 1000°C, the boards retain their physical integrity without releasing toxic fumes or breaking down structurally.
Unlike gypsum, which suffers from dehydration and loss of strength in damp conditions, calcium silicate is hydraulically stable. It does not sag, rot, or swell when exposed to water, making it the premier choice for humid zones, commercial kitchens, and industrial processing areas.
Architects and builders face critical choices when selecting structural panels for fire-rated barriers. Below is a comparative assessment based on ASTM and European standards.
| Performance Indicator | Calcium Silicate Board | Standard Gypsum Board | Fiber Cement Board |
|---|---|---|---|
| Fire Classification | A1 Non-combustible (EN 13501) | Class A / Type X (Limited) | A2 Limited Combustible |
| Dimensional Stability (Wet) | < 0.15% Expansion | Degrades / Sags | < 0.25% Expansion |
| Thermal Conductivity (W/m·K) | 0.12 - 0.20 (Low Heat Transfer) | 0.18 - 0.25 | 0.25 - 0.35 (Higher) |
| Lifespan & Durability | 30+ Years (Inorganic, Mold Resistant) | 10-15 Years (Paper backing prone to mold) | 20+ Years |

Answers to common structural and logistical questions from architects, procurement managers, and contractors.
The physical stability is due to the hydrothermal autoclaving process, which forms a dense crystalline matrix of Tobermorite calcium silicate hydrate. This mineral phase does not lose structural integrity at elevated temperatures. Additionally, the materials contain bound water of crystallization, which is slowly released as steam when heated. This process cools the back side of the board and prevents temperature transmission.
Gypsum contains dihydrate crystals that break down when exposed to ambient moisture, causing structural sag. In contrast, calcium silicate features an interconnected silicate structure that does not absorb moisture via capillary action to the same degree. This prevents swelling, softening, or sagging, allowing installation in sub-tropical climates and wet zones.
We support FOB, CIF, EXW, and DDP terms. To prevent damage during ocean transit, the boards are packed in heavy-duty export crates with edge-protection guards and moisture-resistant shrink wrapping. This packaging prevents physical shock and container moisture damage during transport.
Yes, our boards are manufactured from 100% asbestos-free raw materials. They satisfy the environmental requirements of CE, RoHS, and national green building guidelines. Our products do not release hazardous dust during installation or VOCs when exposed to heat.
