SuperLite II-XL 45 is a fire resistive, technically advanced glazing product that blocks radiant heat transfer to meet ASTM E119 requirements. SAFTI FIRST was the first to provide this new technology to the USA in 1982. SuperLite II-XL products have been tested to the stringent wall standard and therefore are considered a “transparent wall.” Fire resistive glazing allows for greater design flexibility while other fire protective glazing products, such as ceramics, are limited by code to interior applications of 45 minutes or less and to 25% of the wall area.
