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 graphite electrical conductivity?
electrical conductivity of graphite?
What is thermal and electrical conductiuity?
Thermal conductivity refers to the conductivity that is associated with heat. Electrical conductivity refers to the conductivity that is associated with electricity.
What does thermal and electrical conductivity mean?
Thermal and electrical conductivity are physical properties; they represent the ability of materials to conduct heat or electrical current.
What do you call a tool that can be used to test for electrical conductivity?
It is a conductivity tester!
Do nonmetals or metals have high thermal and electrical conductivity?
Both thermal conductivity and electrical conductivity tend to be higher in metals than in most other materials.
If glass is covalently bonded are the electrons free to move and how is this related to the electrical conductivity of glass?
No the electrons are not free to move. This means that the electrical conductivity will be relatively low. -jk
