Glass block with low-e center lite

摘要

A glass block assembly (2) includes first (4) and second (6) glass block halves. A spacer (8) is disposed between the glass block halves to thermally isolate the first glass block half from the second glass block half. A sealant extends from the outer surface of the first glass block half over the spacer to the outer surface of the second glass block half to hermetically seal the internal chamber of the assembly. The spacer has a pair of legs (24) extending laterally outwardly from the body to define shoulders that engage the inner surfaces of the first and second halves. The legs of the spacer define a slot (25). An interior lite (10) is carried by the spacer in the interior chamber.
