I don't understand what you mean.  What is "glazing"?  Like pottery?

If you are new to FDS, then you first need to read the manual guides, glazing would require a pyrolysis model set up correctly.

If you mean glazing, as in windows, it's easy. 
  1. Create a material "glass" with the thermophysical properties of glass. 
  2. Create a surface "window" that specifies the thickness of the window and makes reference to the material "glass". You can also make it almost transparent, and give it a blueish colour for a glass-like appearance.
  3. Create obstructions to represent the glass and apply the surface property "window". If you are importing a 3D CAD or Revit file the windows are usually grouped as "glazing".
See the example below.

&MATL ID='GLASS',
      SPECIFIC_HEAT=0.84,
      CONDUCTIVITY=0.76,
      DENSITY=2700.0/

&SURF ID='WINDOW',
      RGB=102,255,255,
      TRANSPARENCY=0.2,
      MATL_ID(1,1)='GLASS_MATL',
      MATL_MASS_FRACTION(1,1)=1.0,
      THICKNESS(1)=0.005,
      GEOMETRY='CARTESIAN',
      LENGTH=0.0,
      WIDTH=0.0/

The lines describing the surface should have been,

&SURF ID='WINDOW',
      RGB=102,255,255,
      TRANSPARENCY=0.2,
      MATL_ID(1,1)='GLASS_MATL',
      MATL_MASS_FRACTION(1,1)=1.0,
      THICKNESS(1)=0.005/
