This document provides the method of calculation of the thermal resistance and thermal transmittance of building components and building elements, excluding doors, windows and other glazed units, curtain walling, components which involve heat transfer to the ground, and components through which air is designed to permeate.
The calculation method is based on the appropriate design thermal conductivities or design thermal resistances of the materials and products for the application concerned.
The method applies to components and elements consisting of thermally homogeneous layers (which can include air layers).
This document also provides an approximate method that can be used for elements containing inhomogeneous layers, including the effect of metal fasteners, by means of a correction term given in Annex F. Other cases where insulation is bridged by metal are outside the scope of this document.
