Protective screen for improving the fire resistance of building structures

摘要

A protective screen for reducing heat transmitted from a fuel burning stove or the like to an adjacent structural wall surface. The protective screen includes a supporting frame enclosing an area corresponding to the area of the wall surface to be protected. The frame supports a mesh-like screen constructed of high purity copper or the like which permits the free passage of ventilating air therethrough but retards to a relatively great extent the transfer of heat of relatively high temperatures associated with the stove to the adjoining wall surface. The frame is supported in spaced parallel relationship with the adjacent wall by means of a plurality of tubular spacing members in order to provide an air space between the screen material and the adjoining wall. The protective screen eliminates fire hazards when the fuel burning stove is placed close to the adjoining wall.
