Soluble Ceramic Fiber Board (AES Board) – Eco-Friendly High-Temperature Insulation up to 1000°C

What Is a Soluble Ceramic Fiber Board?

A soluble ceramic fiber board, also known as an AES fiber board, is a rigid and lightweight insulation material designed for high-temperature applications up to 1000°C.

Manufactured from alkaline earth silicate (AES) fibers, this board is an eco-friendly alternative to traditional refractory ceramic fiber (RCF) boards, offering improved safety and compliance with modern environmental regulations.


Key Benefits of AES Fiber Boards

  • ✔ Eco-friendly & low biopersistence (safer for workers)

  • ✔ Excellent thermal insulation performance

  • ✔ Rigid structure with high mechanical strength

  • ✔ Easy to cut, machine, and install

  • ✔ Compliant with EU and US environmental standards

Perfect choice for projects requiring both performance and regulatory compliance
