A screen adapted to be placed in front of a hearthfire or other source of radiant heat. A screen is provided for heating a room by convection using the heat from a radiation heat source, e.g. an open hearth fire, a gas-fire or an electric radiant heater, and when the heat source is an open hearth fire for use as a fire-guard preventing sparks or other small particles of combustion from entering the room in which the fire is located. The screen includes a row of at least with their upper portions spaced apart vertical pipes having each at or near their lower end an inlet opening and at or near their upper end an outlet opening for air sucked from the room by the chimney-action of the warm pipes. The pipes of at least one pair of adjacent pipes of the screen are hingedly interconnected for the rotation of one of these pipes about the longitudinal axis of the other pipe thereof by coupling and clamping means.
