High-Performance^TM Low-E4^TM Glass
Renewal by Andersen introduces High-Performance^TM Low-E4^TM Glass, the next generation of energy-efficient, low-maintenance glass, and further advances Andersen's proven glass technology.

Fewer Water Spots and Easier Cleaning
New Low-E4 glass features an innovative titanium dioxide (TiO²) exterior coating, which makes cleaning easier. When this coating is activated by sunlight, dirt loosens from the glass and can be washed away by rain. The special TiO² coating also makes the glass dry faster with up to 99% fewer water spots.

Adds Thermal Protection
Andersen Low-E4 glass employs a hermetically-sealed system for optimum insulation from heat, cold and sound. A patented low-conductivity spacer separates the two panes of glass. The space between the two panes is filled with an argon gas blend to minimize the thermal transfer. Compared to ordinary dual-pane glass, High-Performance Low-E4 glass is 41% more energy-efficient in summer and 35% more efficient in winter. Depending on where you live, that can cut your energy bills up to 25%**.

Helps Keep UV Rays Outside
High-Performance Low-E4 glass works like a sunblock to filter ultraviolet (UV) rays that can fade fabric and damage furniture. Ordinary dual-pane glass lets 63% of UV light pass through. High-Performance Low-E4 glass is layered with 11 microscopic coatings that cut UV transmission down to 17% with virtually no effect on the clarity or color of the light that enters your home.

Reduces Sound Penetration
In addition, High-Performance Low-E4 glass also reduces sound penetration significantly, even when compared to single-pane glass.

Standard Feature
Low-E4 glass is exclusive to select Andersen® windows and doors, and is included as a standard feature on all Renewal by Andersen® window products.

Window Insect Screen Options
Our lightweight insect screens are included as standard with every operable window. They are easy to remove, which makes them easy to clean. All screens are constructed with aluminum frames.
• Fiberglass insect screen cloth (standard)
• Aluminum insect screen cloth (option)
• TruScene^TM insect screen cloth (option) - our new industry-exclusive TruScene screens are made of a micorfine stainless steel that lets in more air and light, providing 50% more clarity than standard insect screens
