1. Product Introduction
The Aluminium Foil Faced Ceramic Fiber Board retains all the inherent properties of ceramic fiber board, such as high-temperature resistance, thermal insulation, lightweight construction, and fireproofing. Additionally, the reflective surface of the aluminium foil significantly enhances its radiant heat barrier performance, improving overall thermal efficiency. It is suitable for high-temperature furnace linings, power and thermal energy equipment, metallurgical industries, chemical pipelines, aerospace components, and building fireproofing applications where thermal reflection, dust prevention, and cleanliness are required.
2. Structure & Composition
The Aluminium Foil Ceramic Fiber Board consists of two layers:
(1) Base Layer: Ceramic fiber board, formed by vacuum forming process from high-purity ceramic fibers, offering low thermal conductivity, good thermal shock resistance, and structural strength.(2) Cladding Layer: Aluminium foil layer, made from industrial-grade aluminium foil, providing excellent reflectivity, moisture resistance, and mechanical strength. It is firmly bonded to the fiber board surface using high-temperature adhesive or thermal lamination technology.
Aluminium foil materials of varying thicknesses and coating strengths can be selected based on the application environment to enhance the board's abrasion resistance and adaptability.
3. Product Features
✓ Excellent Thermal Insulation: Ceramic fiber base material offers low thermal conductivity, suitable for working environments up to 1260°C.
✓ Thermal Radiation Reflection: The aluminium foil layer reflects approximately 95% or more of infrared radiation, significantly reducing heat loss.✓ Effective Dust & Oil Protection: The aluminium foil surface prevents the escape of ceramic fiber dust, making it ideal for equipment spaces requiring high cleanliness.
✓ High Mechanical Strength: Lamination enhances the overall rigidity and compressive strength compared to standard ceramic fiber board.
✓ Easy Installation: Can be cut and drilled, suitable for complex structural surfaces, offering flexible installation.
✓ Moisture & Corrosion Resistance: The aluminium foil layer blocks moisture and chemical agents from the air, extending service life.

10. FAQ
Q1: What is the operating temperature range of the Aluminium Foil Faced Ceramic Fiber Board? Can it be used long-term at 1200°C?
A1: The ceramic fiber base material can withstand temperatures up to 1260°C, and the recommended long-term use temperature range is 1000°C – 1150°C. Please note: the structural stability of the aluminium foil layer at high temperatures is typically maintained up to about 650°C. Therefore, it is recommended to orient the foil face towards the lower-temperature radiation source or use it as a protective layer. For applications exceeding this temperature, options without foil or with alternative reflective coatings should be considered.
Q2: Will the aluminium foil delaminate or oxidize at high temperatures? How is the product lifespan guaranteed?
A2: We use industrial-grade anti-oxidation aluminium foil and employ high-temperature adhesive or thermal lamination technology for a strong bond to the board surface, ensuring good adhesion and heat resistance. Delamination is unlikely within the recommended temperature range (<650°C). For outdoor or humid environments, using edge sealing strips or waterproofing treatments is recommended to extend service life.
Q3: Can the product be customized? For example, size, thickness, or aluminium foil type?
A3: Yes, customization is supported. SUNTHERM can provide products with different densities (220~600 kg/m³), thicknesses (3–100mm), sizes (common ones include 600x400mm, 900x600mm, 1200x1000mm), and structures like single/double-sided foil, perforated foil, etc., based on customer project requirements. Additional treatments like fiberglass cloth overlay or special coatings can also be added.
