A building block (10) for a ventilated wall includes an elongated center portion (12) flanked by a pair of substantially parallel side walls (14, 16) orientated substantially perpendicularly to the center portion (12). The center portion (12) has a first vertical wall (18) and a second sloped wall (20), the second sloped wall (20) extending between a relatively thicker bottom wall (26) of the center portion (12) and a relatively thinner top wall (28) of the center portion (12). The first wall (18) is co-planar with first edges (22, 24) of the side walls (14, 16). A stacked arrangement of such blocks, where adjacent blocks are inverted and reversed, establishes front-to-back air passages (46) that do not provide a sight line, and which prevent rain from passing through. A mold assembly (48) for manufacturing the blocks is also disclosed.

Parpaing pour un mur ventilé qui comprend une partie centrale allongée flanquée par une paire de parois latérales sensiblement parallèles orientées sensiblement perpendiculairement à la partie centrale. La partie centrale comporte une première paroi verticale et une seconde paroi inclinée, la seconde paroi inclinée s'étendant entre une paroi inférieure relativement plus épaisse de la partie centrale et une paroi supérieure relativement plus mince de la partie centrale. La première paroi est coplanaire avec les premiers bords des parois latérales. Un empilage de tels parpaings, où les parpaings adjacents sont inversés et retournés, établit des conduits d'air traversant d'avant à arrière qui ne donnent pas de ligne visuelle et qui empêchent la pluie de pénétrer. La présente invention concerne aussi un ensemble moule pour fabriquer les parpaings.
