How Double Paned Glass Works

Glass is a naturally conductive substance. This is why traditional windows with single-pane glass tend to let heat pass through between indoor and outdoor spaces, which causes heat loss and drafts during the winter season, and increased indoor heat during summer. The heating and air conditioning systems will then need to increase their output to compensate, which will lead to higher utility bills.

Double pane glass is made of two glass panels separated by an airtight space between them. Eliminating contact between interior and exterior surfaces significantly reduces heat conduction, and, consequently, your annual energy consumption.

High-Performance Low-E4 Glass Types

Renewal by Andersen replacement windows are equipped with High-Performance Low-E4® glass, which works together with our Fibrex® material frames in providing long-term performance, beauty, and energy savings.

As a full-service replacement window contractor, we offer the following glass options:

1. High-Performance Low-E4 Glass 

Our standard glass package features low-emissivity (Low-E) tints that selectively block harmful UV rays and solar heat while letting visible light pass through. The outer pane is coated with a layer of metallic oxide that removes up to 99% of water stains when activated by sunlight.

2. High-Performance Low-E4 SmartSun Glass

This glass option provides improved thermal control similar to tinted glass without darkening your indoor spaces. This is ideal for windows that receive direct sunlight from noon to mid-afternoon.

3. High-Performance Low-E4 SmartSun Glass with HeatLock Technology

This option provides all the benefits of our SmartSun glass, but with the thermal control layer applied to the room-facing side. It helps lock in heat in the home during cold days.

4. High-Performance Low-E4 Sunglass

One of our most energy-efficient glass options meets our highest standards in cold climate performance, as well as in sunny climates where direct sunlight can dramatically increase indoor cooling requirements. The High-Performance Low-E4 Sunglass can block up to 95% of solar heat and UV rays.
