Heat transfer through panels - PDF

This report looks at the additional heat loss that occurs at the edge of insulated panels due to lateral heat flow in the panel skin..  

The report describes the findings of a project to assess the influence of edge details on the thermal performance of insulated panels as typically used in stick system curtain walling. It illustrates the problem as it currently exists, through a combination of measurement and computer simulation, and identifies good practice for the design of insulated panels in stick-system curtain walls. 

The report shows good and bad practice and details of calculating accurate U-values for panels in curtain walls.
