GlazeGuard 1000 FR is a composite panel for use as a glazing infill made by laminating two prefinished aluminum skins to a substrate of tempered hardboard. On the other side of the panel a gypsum board stabilizer is used for increased fire resistance. These materials surround a isocyanurate (ISO) foam core. These panels are designed for use as a replacement or complement to glass in windows, storefront, modesty screens, railing inserts, or anywhere else that increased fire protection is desired. Similar in thickness to GlazeGuard 1000 & 1000 WR (all are 1"), these panels offer more fire resistance than the plastic or tempered hardboard compositions. GlazeGuard panels are installed in aluminum glazing/storefront channels (by others) typically on setting blocks and sealed using rubber gaskets. Since they are encapsulated on all four sides by this channel, no mechanical fasteners, adhesives, or moldings are used in the installation of these panels.
