Objectives:

To identify factors governing heat transfer through window and curtain walling frames, to illustrate the relative thermal performance of different frame designs, to examine the effects of 'warm edge technology' glazing spacers, to produce clear design guidance, to aid the designer of thermally improved glazing frames.

The final report comprises: introduction to heat transfer/condensation; simulations of heat transfer through aluminium, timber, PVC-U and steel window frames; simulations of heat transfer through composite window frames (aluminium and steel with timber and PVC-U); simulations of heat transfer through window frames with warm edge glazing spacers; simulations of heat transfer through curtain walling frames, all with ordinary and low-e double glazing.
