PSI and Thermal Bridging - It isn't doing what I expected it to!

In the last couple of weeks we have had one or two queries about what - on the face of it - appear to be excessive thermal bridging included. Thermal Bridging is calculated using PSI data and the construction type. It appears that the type of construction is not being considered as carefully as it should be when entering data.

We have posted a new WIKI article up explaining how PSI values, Thermal Bridging and fabric construction all come together in Part L.  This document is the first from Daniel Touhy in our Dublin office, and it should help clear up any confusion with this methodology.
