Aluminum Foil Coated Ceramic Fiber Board For Thermal Insulation

Product Introduction

Aluminum Foil Coated Ceramic Fiber Board for Thermal Insulation combines the proven advantages of traditional ceramic fiber boards-such as high-temperature resistance, excellent thermal insulation, lightweight structure, and fire protection-with an added layer of aluminum foil for enhanced performance. The reflective surface of the aluminum foil significantly improves radiant heat resistance, effectively boosting overall thermal efficiency while maintaining a clean and durable finish.

 

Aluminum Foil Coated Ceramic Fiber Board for Thermal Insulation is ideal for demanding environments where both thermal reflection and dust control are required. Typical applications include high-temperature furnace linings, power and thermal equipment, metallurgical processes, chemical pipelines, aerospace components, and fire protection in construction.

 

With its dual benefits of insulation and radiant heat reflection, aluminum foil ceramic fiber board provides a reliable and energy-efficient solution for modern industrial and engineering needs.

 

Structure & Composition of Aluminum Foil Coated Ceramic Fiber Board

The aluminum foil ceramic fiber board is engineered with a dual-layer design to deliver superior thermal performance and durability:

Core Layer – Ceramic Fiber Board

Manufactured from high-purity ceramic fibers through an advanced vacuum-forming process, the core offers low thermal conductivity, excellent thermal shock resistance, and reliable structural strength.

Composite Layer – Aluminum Foil

A specialized industrial-grade aluminum foil is firmly bonded to the board surface using high-temperature adhesive or hot-press lamination technology. This layer provides outstanding reflectivity, moisture resistance, and mechanical strength.

Depending on application requirements, different foil thicknesses and coating strengths can be selected to further enhance abrasion resistance and adaptability in diverse operating environments.

This optimized structure ensures that aluminum foil ceramic fiber boards meet the rigorous demands of modern high-temperature insulation, combining thermal efficiency, durability, and clean performance.

 

Key Features of Aluminum Foil Coated Ceramic Fiber Board

Excellent Thermal Insulation – The ceramic fiber core delivers low thermal conductivity, making it suitable for continuous use in environments up to 1260°C.

Infrared Heat Reflection – The aluminum foil layer reflects over 95% of infrared radiation, significantly reducing heat loss and improving energy efficiency.

Dust & Oil Resistance – The foil surface prevents ceramic fiber dust from escaping, ensuring a clean and safe environment, ideal for equipment with strict cleanliness requirements.

Enhanced Mechanical Strength – The composite structure increases rigidity and compressive strength, outperforming standard ceramic fiber boards.

Easy Installation – Boards can be cut, drilled, and shaped to fit complex structures, offering flexible application across industries.

Moisture & Corrosion Protection – The aluminum foil layer blocks moisture and chemicals in the air, extending the service life of the material.

FAQ

Q1: What is the recommended temperature range for aluminum foil ceramic fiber boards?

A1: The ceramic fiber substrate withstands up to 1260°C. For long-term use, we recommend 1000°C–1150°C. The aluminum foil layer itself typically maintains structural stability up to 650°C. For higher temperature applications, consider non-foil boards or alternative reflective coatings.

 

Q2: Will the aluminum foil peel or oxidize at high temperatures?

A2: We use industrial-grade, oxidation-resistant aluminum foil bonded with high-temperature adhesives or hot-press technology for strong adhesion and thermal stability. Under recommended conditions (<650°C), delamination is unlikely. For outdoor or humid environments, we suggest edge sealing or waterproof treatment to extend service life.

 

Q3: Do you offer customized sizes, thicknesses, or foil types?

A3: Yes. SUNTHERM provides custom density (220–320 kg/m³), thickness (10–100 mm), sizes (600×400, 900×600, 1200×1000 mm), and foil configurations (single/double-sided, perforated, multi-layer). Additional options include fiberglass cloth, coatings, and enhanced surface treatments.
