10mm calcium silicate board is a popular building material used across residential, commercial, and industrial projects due to its strength, durability, and fire resistance. In this article, we’ll explore what makes the 10mm version of calcium silicate board ideal for various uses, its technical features, and how to work with it.
Calcium silicate board is a rigid, asbestos-free, fire-resistant board made from silica, lime, and cellulose fibers. The 10mm thickness is a versatile size, offering a balance of strength and workability, making it suitable for walls, ceilings, partitions, and linings.
Fire Resistant: With excellent thermal stability, it can withstand high temperatures, making it ideal for fire-rated partitions.
Moisture and Mold Resistant: Unlike gypsum boards, calcium silicate doesn’t warp or degrade in humid conditions.
Impact Resistant: The 10mm thickness offers good impact resistance, suitable for high-traffic areas.
Lightweight and Easy to Install: Easy to cut, drill, and screw, especially with standard tools.
Asbestos-Free and Safe: Manufactured with safe, non-toxic ingredients, meeting international safety standards.
| Property | Value |
|---|---|
| Thickness | 10mm |
| Density | 1000–1300 kg/m³ |
| Thermal Conductivity | ≤ 0.3 W/m·K |
| Fire Rating | Up to 2 hours (with proper system) |
| Flexural Strength | ≥ 8 MPa |
| Water Absorption | ≤ 35% |
The 10mm board is ideal for a variety of interior and semi-exterior applications, including:
Partition Walls: For commercial or residential drywall systems.
Suspended Ceilings: Especially in moisture-prone areas like bathrooms or kitchens.
Duct and Pipe Insulation Cladding: Due to its heat resistance.
Fireproof Enclosures: In electrical rooms or server rooms.
Wall Linings: On masonry, steel, or timber frameworks.
Industrial Equipment Backing Boards: For high-temperature environments.
Utility knife (for scoring)
Circular saw (with carbide blade)
Dust mask or respirator
Tape measure, T-square, and pencil
Pre-drill screw holes 10–15mm from edges to prevent cracking.
Use galvanized steel framing or treated timber studs.
Seal edges and joints with a compatible filler or joint tape.
Avoid exposure to prolonged water contact unless sealed or coated.
Compared to gypsum board or fiber cement board, 10mm calcium silicate board offers:
Superior fire performance
Better dimensional stability in humid environments
Longer lifespan
Minimal maintenance
You can find 10mm calcium silicate boards at construction material suppliers, hardware stores, or through online industrial distributors. Look for reputable brands that meet international standards such as EN, ASTM, or ISO certifications.
10mm calcium silicate board is a smart, reliable choice for both new construction and renovation projects. Its combination of fire safety, durability, and ease of installation makes it ideal for a wide range of applications.
Whether you're building a commercial office or upgrading a residential bathroom, 10mm calcium silicate board provides the performance you can count on.
Q: Can 10mm calcium silicate board be used externally?
A: It can be used in semi-exposed areas but should be coated or sealed if fully exposed to rain.
Q: Is it safe to cut calcium silicate board indoors?
A: It's best to cut outdoors or in well-ventilated areas while wearing a dust mask.
Q: How heavy is a 10mm board?
A: Depending on density and size, a 10mm board typically weighs around 12–15 kg per square meter.
