Units & Terminology Explained
  • U value is the measure of how much heat is being lost through the wall, floor or roof section of a building.
  • U Value is measured in Watts per metre squared Kelvin and is written as W/m2K
  • Thermal Conductivity is the measure of a materials ability to conduct heat.
  • The lower the thermal conductivity the better the insulator.
  • Thermal Conductivity is measured in Watts per metre Kelvin
  • The thermal conductivity of Kingspan Ecobead Platinum is 0.033W/m.K

Heat Transfer

Heat is transferred in 3 ways Conduction, Convection & Radiation.

•    Conduction

Conduction through solid material or gas: the better insulating the material, the less the conduction

•    Convection

Heat "travels" through air movements because of temperature and density gradient. Hot air moves up and heat dissipates. The stiller the air, the less the convection

•    Radiation

Each material absorbs or emits thermal radiations depending on its temperature and its emissivity .Heat exchange is function of propagation media (vacuum or air) When radiation is absorbed or reflected , there is less thermal transfer.
