ENERGY-EFFICIENT WINDOWS

Masterpiece Leaded Windows has become the leader of the leaded glass industry by changing from a single-pane line to our new Energy-Tech™ triple-pane leaded glass windows. We've engineered our triple-pane windows, exceeding all Energy-Star® requirements, to add elegance to the home while providing year-round comfort. Optional Low-E blocks infrared light and reduces ultraviolet light.

When compared to single-pane or dual-pane glass, Energy-Tech triple-pane leaded windows can make a dramatic difference in your home.

WHAT IS LOW-E?

Low-E is a clear, low-emissivity coating applied to one side of the glass in our triple-pane windows. This thin coating filters the sun's energy in the summer and reduces heat loss in the winter, making even energy bills look better.

Benefits of Low-E
  • 1. Low-E allows most natural light to enter freely but absorbs a significant portion of short-wave heat energy.
  • 2. In the summer, long-wave heat energy radiating from objects is reflected back outside, lowering cooling cost.
  • 3. In winter, internal long wave heat energy is reflected back inside, lowering heating cost.
