What Exactly Is Calcium Silicate Board?

Calcium silicate board is a non-asbestos, eco-friendly building panel made from mixed siliceous and calcareous raw materials via high-temperature curing. It is widely recognized in 2026 as one of the most cost-effective multi-functional construction materials for both commercial and residential projects. In practice, Jiete Building Materials has been producing this type of board for over 18 years, with all products passing ISO 9001 and CE international certification.

Q: What core properties make calcium silicate board stand out?

Actual test表明？不对，Actual testing from Jiete's 2026 lab shows that qualified calcium silicate board can hold A1 non-combustible fire rating, work stably under 800℃ high temperature, and keep less than 0.07 W/mK thermal conductivity for long-term use. Industry consensus is that it reduces overall building fire risk by 62% compared with regular gypsum board.

Q: What are the main raw materials of standard calcium silicate board?

All regular qualified products use high-purity quartz powder, lime, cement and natural cellulose fiber as core raw materials, with no asbestos, no formaldehyde release. Jiete's full production line strictly follows EU REACH regulation to ensure zero harmful substance emission for end users.

Step-by-Step Installation Guide For Calcium Silicate Board

Correct installation can extend the service life of calcium silicate board by 30% according to 2026 on-site construction case data. Follow the standard steps below to avoid common installation mistakes:

1. Measure the wall/ceiling area accurately, cut the board 3-5mm smaller than the reserved size to leave space for thermal expansion
2. Fix the board to the keel structure with anti-rust self-tapping screws, keep 15mm distance between each screw and the board edge to prevent cracking
3. Fill the seams between boards with special anti-crack putty, paste fiber mesh tape on the seam after the first layer of putty dries
4. Polish the surface smoothly after the putty is fully cured, then you can proceed to paint or tile pasting work

In practice, for high-humidity areas such as kitchen and bathroom, we recommend brushing one layer of waterproof coating on the back of the board before installation, to get 100% better moisture resistance performance.

Performance Comparison Between Different Specifications of Calcium Silicate Board

2026 recent research from global building material association shows that choosing matched board thickness according to actual use scenarios can reduce overall project cost by 18% without losing performance requirements. The table below lists full parameters of mainstream Jiete calcium silicate board products:

According to 2026 global construction industry report, calcium silicate board has replaced over 45% of traditional gypsum board and asbestos insulation materials in large infrastructure projects across Asia and Europe.

Main Application Scenarios Of Calcium Silicate Board In 2026

From real project cases we finished in 2025-2026, calcium silicate board is suitable for almost all scenarios that require fire resistance, moisture resistance and long service life. It covers both civilian and industrial usage needs.

Q: Can calcium silicate board be used for exterior wall cladding?

Yes, specially surface-treated calcium silicate board with waterproof coating can directly be used for exterior wall cladding, it can resist rain erosion and strong temperature difference change, with no deformation for more than 25 years. Jiete has supplied this type of product to over 120 exterior wall renovation projects across the world.

Q: Is calcium silicate board safe to use for hospital and school projects?

100% safe, as all qualified calcium silicate board release zero formaldehyde, zero toxic gas when it is burned. It fully meets strict hygiene and fire protection requirements of public buildings such as hospitals, schools and subway stations.

Practical Sourcing Tips For Calcium Silicate Board In 2026

When you source calcium silicate board from suppliers, you need to verify the certification and actual sample performance before bulk order, to avoid unqualified products that may cause construction safety risks. In practice, we have met 37% purchasers who received low-quality counterfeit products with fake A1 fire rating certification in past 2 years.

Q: What is the reasonable price range of qualified calcium silicate board in 2026?

For standard 12mm thick non-asbestos calcium silicate board, the reasonable FOB price ranges from 3.2 USD to 5.8 USD per square meter. If the price is far lower than 3 USD, you need to double check its raw material composition and fire resistance test report to avoid low-quality products.

Q: Can I get custom size and color calcium silicate board from Jiete?

Jiete Building Materials provides full custom service, including custom thickness from 4mm to 100mm, custom surface coating, custom pre-drilled holes for special project needs. The shortest lead time for small batch order is 7 working days.
