Spectra Glaze® glazed units are pre-faced architectural concrete masonry blocks that have a thermoset 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. Special manufacturing processes are used to provide a permanent, impervious glazed finish with exceptional resistance to staining, abrasion, impact and chemicals.
