   You can buy anchors that transfer load back to stud. See http://www.heckmannbuildingprods.com/steel_stud_anchors.html
   Of course, they bridge your insulation, which is what you were trying to avoid.

   Hi user-XXX (be nice to have a real name for our GBA Q&A community) -

   Hey Peter, Joel
   My name is Gay...

   Thanks for the info...

   What cladding does not introduce thermal breaks?

   A quick search located these fiberglass brick ties: http://www.qwikfixings.com/glass-fibre-wall-ties. Fiberglass is as strong as steel, but has far lower thermal conductivity.

   These are only certified to UK standards, but I bet somebody is making them in the states. Or they certainly should be.

   Your brick shelf will still be a thermal short and that one is harder to deal with.

   Thanks Peter...
   These seem to be for a concrete block to brick veneer application - but I've asked the manufacturer for their input.

   Do you (anyone?) think it would it be possible to put a layer of EXP 100psi on the brick ledge, (under the brick) or is that just asking for trouble?
   (Below grade will have insulation.)

   The concrete that brick sits on in in the region of 3500 psi. You would need a material in that range, which would also not deform under load.

   Thermally broken shelf angles for bricks exist, but may not be economical (or even available) for residential scale products. Here's one: https://www.armatherm.com/applications/masonry-shelf-angle-thermal-bridging-solution/

   Another approach is to support the metal angle on welded knife plates. See Photograph 6b here: https://buildingscience.com/documents/insights/bsi-005-a-bridge-too-far

   Again, you will have to assess the practicality of these techniques on a residential project, but hopefully it at least gives you some ideas!

   Perhaps a better trick is to avoid the problem altogether by insulating on the interior of your basement foundation and supporting the bricks on the foundation, kind of the opposite of figure 5 in this article (instead use the insulation scheme in figure 10, but with bricks): https://buildingscience.com/documents/digests/bsd-103-understanding-basements.

   Or in a slab on grade, you could do some variation of figure 4 in this article: https://buildingscience.com/documents/insights/bsi-059-slab-happy

   The brick ties still create small thermal bridges, but you eliminate the big bridge at the bottom from the metal shelf angle at least.

   For masonry ties, maybe look into HB thermal wing nut anchors: http://www.h-b.com/index.php?main_page=index&cPath=93_76_138.

   For shelf angle supports, try the FAST system by Fero: http://www.ferocorp.com/technical_notes/FAST.pdf. You'll need to make sure your headers are engineered to support the loads though.

   RDH published an interesting study of the FERO product line: http://www.ferocorp.com/technical_notes/FERO_Thermal_Analysis.pdf

   The mason we use hates the FERO rap ties so we're using the wing nuts instead. But we're doing full bed masonry on top of 3" Rock Wool

   Good luck!
