Window manufacturers know that stopping heat transfer is essential in providing an energy-efficient window. To do that, many manufacturers use low-e glass, which is window glass coated with multiple layers of UV protection that keeps the sun’s rays from penetrating into the home. But not all low-e glass is created equal. While most energy-efficient glass offerings feature two layers of protection, the Thermostat glass exclusively available in Performax54 windows features three low-e layers.
What does that mean? Thermostat glass makes Performax54 windows a true energy-efficiency workhorse with 50% more energy efficiency than standard low-e windows. That translates to energy savings that goes right into your pocket!
