## Abstract

Protective panels are disclosed for insulating walls and other combustible surfaces from a nearby stove or other heating device. Simple, economical shallow U-shaped pieces, one positioned upon the other, create two distinct conduits through which air flows upwardly. Also, the panels reflect radiant heat back towards the stove or other heat source and away from the area protected. A plurality of these double conduit panel members provide an insulating barrier between the heat source and the combustible surface to cover areas of any desired size.

## Claims

### Claim 1

In combination with a wall, a panel for insulating such wall from a stove or like heat source,
said panel comprising an inner elongate panel member of U-shaped cross-section and having a wall portion spaced from and parallel to said wall and opposite vertically extending first side legs extending from said wall portion to said wall thereby to define with said wall a vertically extending channel,
an outer elongate panel member of generally U-shaped cross-section having a front wall portion spaced from and extending parallel to said inner panel member wall portion,
said front wall portion being of narrower width than said inner panel member wall portion,
said outer panel member having opposite second side legs, each having a first portion extending perpendicularly to and between said inner and outer panel member wall portions, a second portion extending outwardly from said first portion and parallel to said inner panel member wall portion in engagement therewith, and a third portion extending parallel to said first portion toward said wall in engagement with the outer surface of said first legs,
and a plurality of fasteners extending through said second leg portions and said inner panel member wall portion and into said wall thereby to secure said panel members to said wall and to provide a pair of parallel channels for the conduction of air therethrough.

### Claim 2 (depends on 1)

The combination of claim 1 wherein the outer surface of said front wall portion is provided with a heat absorbing coating.

### Claim 3 (depends on 2)

The combination of claim 2 wherein the outer facing surface of said wall portion is provided with a heat reflective surface.
