Product Overview
We launch high-quality calcium silicate board series products, made from high-grade calcium silicate, quartz sand, fibers and other core raw materials through high-pressure molding and high-temperature curing processes, integrating excellent fire resistance, moisture resistance, high strength, impact resistance and environmental stability. With a simple and practical design, the products meet the needs of various indoor and outdoor decoration and functional spaces. They can not only serve as load-bearing substrates to ensure structural stability but also meet strict requirements such as fire protection, sound insulation and environmental protection. It is an ideal choice for architects, decoration companies, contractors and owners for partitions, ceilings, exterior wall decoration and floor substrates, widely applicable to commercial, public, residential, industrial and other scenarios.

Product Features
Top-level Fire Resistance: Class A1 non-combustible material, does not burn or produce toxic fumes when exposed to fire, fire resistance limit up to 2–4 hours, providing core protection for space safety.
Strong Moisture & Mildew Resistance: Inorganic material properties, low water absorption, not easy to deform, mold or moth-eaten in humid environments, suitable for damp spaces such as kitchens, bathrooms and basements.
High Strength & Impact Resistance: Dense structure and reinforced fibers ensure excellent flexural, compressive and impact resistance, long service life, and can be used as load-bearing substrates.
Environmental & Healthy: Formaldehyde-free, odorless, no radioactivity, meets green building requirements, harmless to human body, suitable for sensitive crowd spaces.
Multifunctional Adaptability: Possesses certain sound insulation (sound insulation capacity up to 30–40 dB) and thermal insulation performance, meeting different space functional needs; surface can be directly painted, tiled or wallpapered, with strong decorative plasticity.
Easy & Efficient Installation: High flatness, simple cutting, multiple installation methods optional, high construction efficiency and reduced labor costs.
Excellent Weather Resistance: Inorganic material is anti-aging and corrosion-resistant, can be used in semi-outdoor environments (such as exterior wall dry hanging, balcony ceiling), with stable performance during long-term use.

Frequently Asked Questions (FAQ)
Q1: What is the service life of the calcium silicate board?
A: Under normal use and maintenance conditions, the service life can reach 20–30 years for indoor use and 15–20 years for outdoor (semi-outdoor) use, depending on the use environment and installation quality.
Q2: Can the board be directly used in humid spaces such as bathrooms and kitchens?
A: Absolutely. The product has strong moisture resistance, low water absorption, and is not easy to mold or deform, making it the preferred substrate for kitchen and bathroom walls and ceilings; it is recommended to seal the joints during installation to improve moisture resistance stability.
Q3: What is the difference between calcium silicate board and gypsum board?
A: The core difference lies in moisture resistance and fire resistance: calcium silicate board is a Class A1 non-combustible material with excellent moisture and mildew resistance, suitable for humid environments; gypsum board is mostly Class B1 fire-resistant with weak moisture resistance, more suitable for dry indoor spaces. In addition, calcium silicate board has higher strength and can be used as a load-bearing substrate.
Q4: Are professional tools required for cutting and installing the board?
A: Cutting requires a diamond saw blade or special cutting tools, which is easy to operate; the installation process is standardized, and it is recommended to be installed by a construction team with decoration experience to ensure installation firmness and flatness.
Q5: How to clean and maintain it daily?
A: Daily cleaning can be done by wiping surface dust or stains with a damp cloth, no special maintenance is required; avoid long-term immersion in water or contact with strong corrosive chemicals to prevent damage to the board's performance.
Q6: Can the product's fire resistance pass the fire acceptance inspection?
A: Yes, the product is a Class A1 non-combustible material, fully complying with the national standard GB 8624-2012 "Classification of Burning Performance of Building Materials and Products", and has passed the testing and certification of authoritative institutions, which can successfully pass the fire acceptance inspection.
Q7: Does it support personalized customization?
A: Yes. We can customize special sizes and thicknesses (such as ultra-thin 3mm, extra-thick 25mm) according to project requirements, and also customize functional surfaces such as film-coated, antibacterial and anti-static surfaces. For details, you can communicate with the business team.
