What are Low-E coatings exactly?

Low-E, or Low Emissivity surfaces reduce the amount of heat that passes through a window while still allowing light to pass through. The level of heat that passes into your home is measured by the level of ultraviolet light that passes through your windows All materials absorb, reflect, and emit thermal energy.

What is Low E Glass

This comes as a huge opportunity for homeowners who are concerned about their overall energy costs.By reflecting heat this way, especially during Florida’s extended warm months, your air conditioner will run considerably less as your home will stay cooler for longer. This directly and immediately reduces your monthly energy bill, translating into huge savings. This also adds to your home’s overall level of comfort.
