YHS 50 TU is a high performance pre-glazed or field glazed storefront system designed for insulating glass 1″ to 1-5/16″ thick and tested to meet the most demanding conditions. With varied infill and components, YHS 50 TU can meet the requirements for Impact Resistance, Blast Mitigation or both. YHS 50 TU is thermally broken by means of a poured and debridged pocket that employs ThermaBond Plus® to greatly improve the adhesion of the polyurethane to the extruded aluminum. The system features the Model 35H entrance door with maximum-security dead bolts or optional exit devices for egress requirements. A pre-glazed option is now available along with the field glazed system.
