Tie-backs and shelf angles are required for masonry veneer walls, which create significant thermal bridges and can diminish a wall's R value by up to 50%, making it difficult to fulfil energy requirements. The masonry weight is transferred back to the building's structural steel or concrete slab edge, interrupting the wall assembly's continuous insulation and generating a linear thermal bridge.

The shelf angle can be linked to the structure at discrete, uniformly spaced points such as plate "blades" to increase the U value of a masonry wall assembly, allowing the insulation to travel behind the steel angle and eliminating the impacts of a continuous thermal bridge. Building the shelf angle outwards, on the other hand, necessitates larger geometries and more material to sustain the cantilevered load.
