On the glenwood, how far does the actuall stove stand from the back wall? I am trying to visualize where it will sit when I buy one. Maybe you could give me the width and height on the 6 ?
The base on the No 6 is 24"x24" (and some change) not sure on the No 8 though. The height without Finial is 48" off the floor and the center of the rear flue exit is 25" from the floor.
Here is the r value chart i referred to in an earlier post,
R Values of common hearth materials
Q: My new woodstove's installation manual calls for a non-combustible hearth (floor protection) extending so many inches beyond the rear and sides of the stove and in front of the loading door. This much I understand. The manual also states this floor protection must have an "R" value of at least 0.800. This part I don't understand: what is an R value, and how do I ensure that my hearth material meets the minimum requirement?
R-value is a measurement of the insulating properties of a given material at a given thickness. Here's a chart showning the R-values of several common hearth materials:
Material Thickness R-Value
Mineral Fiber Board ( Micore 160 ) 1/2" 1.270
Ceramic Board ( Rescor 360 ) 1/2" 1.110
Ceramic Board ( Fiberfrax Duraboard LD ) 1/2" 1.100
Mineral Fiber Board ( Micore 300 ) 1/2" 1.030
Common Brick 4" 0.800
Common Brick 2-1/4" 0.450
Gypsum or Plaster Board 1/2" 0.450
Cement Board ( Durock Next Gen) 1/2" 0.390
Cement Board ( Wonderboard ) 1/2" 0.260
Cement Board ( Hardibacker 500 ) .42" 0.200
Limestone 1" 0.153
Cement Board ( Hardibacker ) 1/4" 0.130
Cement Mortar 1/2" 0.100
Slate 1" 0.100
Concrete 1" 0.095
Marble 1" 0.090
Granite 1" 0.083
Ceramic Pavers 1" 0.080
Flagstone 1" 0.079
Sandstone 1" 0.079
Ceramic Tile 1/4" 0.020
As the chart shows, you can achieve the required R-value of 0.800 with 1/2" of Fibrefrax or Micore, 8-1/2" of poured concrete, or one layer of 4" brick. You can also meet your requirement by stacking layers of the materials listed: ie, 4 layers (1.68") of .42" Hardibacker would give you the 0.800 R-value you require.
