The heat tansfer coefficient of a substance is the quantity of heat that passes in unit time through unit area of a plate of particular thickness when its opposite faces differ in temperature by one kelvin. As such, it is defined in terms of k/L where kis the thermal conductivity of the substance and L is the thickness of the plate. A good general value for the thermal conductivity for glass would be 1.1 W/m∙K, but different kinds of glass will differ somewhat from this value.
Acryilic "Glass" (aka Plexiglas) has a value of 0.17-0.19 W/m∙K
Fiberglass has a value of about 0.045 W/m∙K
Window glass is about 0.8 - 0.93 W/m∙K
Pure SiO2 has a value of 1.0 W/m∙K and 96% pure SiO2 can be 1.2-1.4 W/m∙K
Pyrex glass has a value of 1.005 W/m∙K
Quartz (single crystal) has a value of 12 W/m∙K parallell to the central crystal axis and 6.8 W/m∙K perpendicular to the crystal axis.
Vitreous or Fused silica is 1.46 - 3 W/m∙K

What is the electrical conductivity of stainless steel?
Stainless steel has low electrical conductivity compared to other metals.
If glass is covalently bonded are the electrons free to move and how is this related to the electrical conductivity of glass?
In glass, the electrons are not free to move due to the covalent bonds holding the atoms together. This lack of free-moving electrons leads to glass being an insulator with low electrical conductivity.
