French to English Tech/Engineering Architecture

Hi there,

Does anyone know what the English equivalent of a 'mulot' would be (in the context of bricks, not field mice!)?

Here's the full sentence for context:

"Plus économique que la brique de parement traditionnel, le mulot permet entre autre la pose à joints creusés (contrairement aux solutions de plaquettes)."

P31 of this PDF shows what a 'mulot' looks like compared to other facing bricks:

My understanding is that a 'mulot' is thinner than a standard facing brick, but thicker than a brick slip. I've seen it referred to as a 'demi brique' (see below) but haven't found any convincing English-language references to 'half-bricks':

Plaquettes et demi briques (mulots)
Elles sont coupées dans les briques et présentent donc les mêmes caractéristiques que les briques de parement classiques. La plaquette a une épaisseur de ±2 cm tandis que la demi-brique ± 4,5-5 cm.

Thanks in advance for your help!
