Tempered Clear Glass is used in our Alpha I & Omega I Windows and Doors. It is the next generation in our product line of high-performance single pane glass. The patented Duralite design features a unique composite laminating technology without the use of metal, resulting in superior thermal and durability performance. The multilayer, highly efficient spacer uses proven components, sealants and desiccants to produce improved condensation resistance, a warmer edge of glass temperature.
