Astra-Glaze glazed block offers color and durability to projects. Glazed blocks are lightweight concrete blocks that have a thermosetting glazing compound permanently molded to the face. The compound is heat-treated and becomes an integral part of the block. Many shapes and sizes are available to meet the designers needs.

ASTRA-GLAZE-SW®+ glazed units are concrete masonry blocks which have a thermosetting glazing compound permanently molded to one or more faces. This glazing compound is cured and heat treated in gas-fired tunnel kilns thus becoming an integral part of the unit.

The glazed facings are molded in individual molds, assuring dimensional uniformity of the glazed facing regardless of minor variations in the block. Glazed concrete blocks are lightweight units conforming to ASTM C90 Type 1. Special manufacturing processes are used to provide a permanent, impervious satin glazed finish with exceptional resistance to staining, abrasion, impact, and chemicals.
