HEARTH ExTENSION

A hearth extension projecting a minimum of 

20" in front of and a minimum of 12" beyond 

each side of the fireplace opening is required 

to  protect  combustible  floor  construction 

in  front  of  the  fireplace.  Fabricate  a  hearth 

extension using a material which meets the 

following specifications: a layer of noncom

-

bustible, inorganic material having a thermal 

conductivity of K=0.84 BTU IN/FT, HR. F (or 

less) at 1" thick. For example, if the material 

selected has a K factor of 0.25, such as glass 

fiber, the following formula would apply:

 

0.25

 x 1.0" = 0.30" thickness required

 

0.84

Thermal conductivity "K" of materials can be 

obtained from the manufacturer or supplier of 

the noncombustible material. If the hearth ex

-

tension is to be covered, use noncombustible 

material such as tile, slate, brick, concrete, 

metal,  glass,  marble,  stone,  etc.  Provide  a 

means to prevent the hearth extension from 

shifting and seal gap between the fireplace 

frame and hearth extension with a noncom

-

bustible material (see Figure 3). 

 WARNING: Hearth extension 

is to be installed only as shown 

in Figure 3.
