Thermal transmittance
also known as U-value; is the rate of transfer of heat per second through one square metre of a structure divided by the difference in temperature across the structure; is the reciprocal of the total thermal resistance.

thermal resistance
heat property and a measurement of a temperature difference by which an object or material resists a heat flow

thermal conductivity
thermal conductivity (often denoted k, ?, or ?) is the property of a material to conduct heat

"Flow resistance at elevated temperature / resistance to heat"
resistance to melting at high temperatures

water vapour diffusion equivalent air layer thickness
water vapour diffusion resistance factor multiplied by the thickness of the material

water vapour diffusion resistance factor
the relationship between the water vapour diffusion resistance of a material compared with that of a layer of dormant air in the same thickness as the material. This is expressed in the form of a factor, with the air layer as the basis. The larger the factor of the material, the greater is the resistance of the material to the diffusion of water vapour.
