Abstract: A structural member acts for distance keeping, stiffening and load-supporting structural framing between a first building structure and a second building structure across which there exists a temperature differential, for example the inner and outer casings of an air handling unit supported externally of the building so as to be exposed to outdoor weather. The structural member has a web portion spanning between mounting portions connecting opposing first and second edges of the web portion to the first and second building structures respectively. A plurality of slots are penetrated through the web portion at spaced apart locations relative to one another to be primarily non-parallel to the first and second edges. Some of the material bridges between the slots require heat transfer across the bridge to travel opposite to the direction of the temperature gradient direction.
