What Is Low-E Glass?

If you need replacement windows, look for products with low-E glass, particularly our High-Performance™ Low-E4® glass. This revolutionary glass package works to reduce heat transfer, thereby saving you money in energy bills. Here’s how it works.

Heat Transfer

During a hot summer day, the heat from the sun hits your window at full force. Because glass is a conductive material, sunlight penetrates into your home. You see this as daylight and feel it as heat. To compensate for the sunlight that’s heating up your interior, your air conditioner has to work overtime. Your energy bills probably increase significantly in the summer as a result of all the energy your air conditioner has to consume. Fortunately, windows with High-Performance™ Low-E4® glass are a cost-effective solution.

Why Invest in Low-E Glass?

When it comes to heat, the coating of the glass makes a big difference. Low-E glass is coated to combat heat radiation. It acts as a restrictive gate, cutting down on the amount of infrared rays (which cause heat transfer) that reach the inside of your house. This thin coating is made of highly reflective materials to keep these infrared rays from entering your home.

Low-E Products

All our window products, from casement to sliding windows, are equipped with low-E glass. They’ve all been tested for heat insulation and have passed with flying colors. For example, our specialized Low-E4 SmartSun™ glass has been tested to be 70% and 45% more energy-efficient than ordinary glass in summer and winter, respectively.
