'Conventions for U-value calculations' guides
the architect and specifier for calculating
U-values by:
- indicating the methods of calculation appropriate for different construction elements: roofs, walls, floors, basements, windows and doors
- providing further information about using the methods
- providing data relevant to typical UK constructions.
Particular guidance is given on thermal conductivity of materials, and on various issues commonly arising when calculating U-values and how they apply to different construction types.

This 2006 edition of the guide is fully updated in line with Part L of the Building Regulations that came into effect in April 2006. 44 pages.
