Armatherm™ FRR

Masonry Shelf Angle

Masonry veneer walls require tie-backs and a masonry shelf angle which form significant thermal bridges and can reduce a walls’ R value by as much as 50% making it difficult to meet energy codes. Shelf angles transfer the masonry load back to the buildings’ structural steel or concrete slab edge interrupting the continuous insulation of the wall assembly creating a linear thermal bridge.

To improve the U value of a masonry wall assembly, the shelf angle can be connected to the structure at discreet, evenly spaced points such as plate “blades” allowing the insulation to pass behind the steel angle, thus reducing the effects of a continuous thermal bridge. However, building the shelf angle outwards requires larger geometries and additional material to support the cantilevered load.

Improving Wall Assembly Efficiency

Improving Wall Assembly Efficiency

Alternatively, Armatherm™ FRR structural thermal break material can be used directly behind the masonry shelf angle as a thermal break within the insulating layer. The Armatherm™ thermal break significantly reduces the linear transmittance (heat loss) of the shelf angle connection. Rigid, metal flashing used as waterproofing can also be replaced with a non-conductive, self-adhered membrane to reduce the effects of thermal bridging further.
