Description
This is a series of four volumes. Two volumes deal with thermal transmission and temperatures within curtain walling; two further volumes consider the assessment of condensation risk in curtain walls. The four volumes are:
Standard for specifying and assessing for heat transfer (the U-value)
Guide to good practice for assessing glazing frame U-values
Standard for specifying and assessing for condensation risk
Guide to good practice for assessing heat transfer and condensation risk for a curtain wall
These documents set out the rules for performing thermal analysis of glazing frames and take the reader through worked examples of U-value and condensation risk analysis.
Compliance with the guidance given in these documents will ensure that full account is taken of thermal breaks, cold bridges and lateral heat transfer within the wall. Earlier simpler methods of analysis are not capable of representing the true behaviour of walls with complex geometry.
