For even higher performance, Masterpiece offers these window glass options.


Tempered glass is extremely strong and often used for its safety characteristics. Not only is it extra strong, but when it breaks, it breaks into little pebble-like pieces without sharp edges. Tempered glass is ideal for reducing the likelihood of injury in the event of window breakage in applications like side lights, stairwells, and over bathroom tubs.

Low-E Glass

Low-E Glass keeps interiors cooler in summer and reduces heat loss in winter. Low-E Glass can be used for any of our triple-paned leaded glass windows.
