Product Description

Rigid Backing Aluminum Silicate Fiber Board Furnace Wall Insulation Panel

Product Description

Aluminum Silicate Fiber Board, also known as ceramic fiber board or alumina-silicate insulation board, is a rigid high-temperature insulation board manufactured from high-purity alumina-silicate fibers through a wet vacuum forming process. This forming method gives uniform fiber distribution and consistent density, producing a board with good mechanical strength, stable dimensions and dependable thermal performance at elevated temperature.

This grade is made for furnace backing and hot-face support. It suits furnace wall and roof backing, kiln lining support, and load-bearing insulation behind refractory brick and castables.

The rigid board takes compression and mechanical load without deforming, resists thermal shock and is non-combustible and chemically stable. A small amount of organic binder gives the board handling strength and burns off gradually on first heating around 250–400°C, producing a light, brief smoke.

Product Features

Rigid Formed Structure – Takes compression without deforming.

Furnace Backing Board – Hot-face support and kiln wall backing.

Refractory Backup Panel – Load-bearing insulation behind brick and castables.

High Temperature Resistance – Stable up to a classification temperature of 1200°C.

Class A1 Non Combustible – Adds passive fire protection.

Easy Installation – Rigid panels fit quickly on site.
