Abstract

This invention relates to mounting porous ceramic material to metal surfaces. The metal surfaces may either be flat surfaces or tubes. The ceramic material is held onto a perforated metal sheet by screwed-in spiral springs. The perforated metal sheet acts as a holding device and is located adjacent to a metal surface. The invention provides for porous ceramic insulation which is conveniently mounted with relation to the metal surface. Spiral springs absorb the stresses which occur during use.
