What is the thermal conductivity of electrical insulators?
Thermal conductivity of electrical insulators are between 0.1 to 3.0 W/mK. For example, plastic has a conductivity of between 0.1 - 0.5 W/mK

Polystyrene insulation is used in a waffle slab construction having a thermal conductivity of between 0.03-0.04 W/mK.
Thermal breaks are thin insulating materials used to reduce thermal bridging in a wall, floor or a ceiling. Common thermal breaks are EPS strips, rubber or timber battens.
For fiberglass insulation with a density of 7 kg/m3, it is 0.057 W/mK, and for a density of 12 kg/m3, it is 0.044 W/mK.
The best insulation between 140mm rafters is R4.0 insulation, which is the equivalent of a 140mm Glasswool insulation with a density of 32 kg/m3.
The best insulation for 90mm stud walls is R2.7 insulation, [...]
Thermal conductivity of Glasswool batts depends on the density of the insulation. Here are some examples (in W/mK): 11 kg/m3: 0.046...
Typical insulation thermal conductivity values (in W/mK) are: Cellulose fibre: 0.04, Fibreglass (7 kg/m3): 0.057...
