Summary:To provide an incombustible back-up material having heat resistance equal to or higher than that when an RCF is used, not subject to a specific chemical substance damage prevention rule, and capable of suppressing fiber scattering during a cutting processing.SOLUTION: The incombustible back-up material fitted to an inner peripheral groove of a sash of a glass door is formed in felt by stacking a polyester unwoven layer and an inorganic fiber layer including a glass fiber and alkali earth silicate wool one by one. An inter-fiber binding material is impregnated in the entire incombustible back-up material.SELECTED DRAWING: Figure 1 【課題】本発明は、ＲＣＦを用いた場合と同等以上の耐熱性を有し、かつ、特定化学物質障害予防規則の制限を受けず、さらに、切削加工時に繊維の飛散を抑制できる不燃性バックアップ材を提供する。【解決手段】ガラス戸のサッシの内周溝に装填される不燃性バックアップ材であって、ポリエステル不織布層と、ガラス繊維及びアルカリアースシリケートウールを含む無機繊維層とが少なくとも１層ずつ積層されてフェルト化されたものであり、前記不燃性バックアップ材全体に繊維間結合材が含浸されているものであることを特徴とする不燃性バックアップ材。【選択図】図１
