The framing, anchoring and installation details are the same as installing any non-fire rated glass block panel and as shown in our published literature. The one distinct difference is that the sealant used at the jamb and head locations must be a fire retardant type sealant. Also all 90 minute rated glass back window assemblies may only be installed within masonry or concrete walls, may only by framed and anchored with inch thick steel channels or angles that form channels; and the expansion material within the channels must be doubled (or inches thick). Finally our VeriTru® plastic spacers are listed by Underwriters Laboratories under Classification Number R 18572 and can be used to construct fire rated glass block window assemblies. • Click here for Glass Block plastic spacer results.
