Specialty Windows: When Regular Windows Won’t Do

Some homes demand extra attention. That is why Renewal by Andersen of Alaska offers a full line of specialty windows for our local customers.

Our specialty windows are made of the same advanced materials as our traditional window styles, including High-Performance™ Low-E4® SmartSun™ glass panes and frames built using our innovative Fibrex® material. The difference is that these windows can be designed to fit the dimensions of your space, and personalized further with your choice of color, hardware and grille styles.

What you get is a window that is uniquely yours.

High Performance™ Low-E4® SmartSun™ Glass
Different Glass Types

Renewal by Andersen® introduces the next generation of low-maintenance, energy efficient glass with High Performance™ Low-E4® SmartSun™, furthering the Andersen® advantage.

Easier Cleaning and Fewer Water Spots
Andersen® High Performance™ Low-E4® SmartSun™ glass employs a revolutionary titanium dioxide (TiO²) exterior coating, making it easier to clean. Upon activation, sunlight loosens any dirt adhered to the surface which can then be washed off by natural rain water. The coating also enables the glass to dry more quickly with as much as 99% fewer water spots. *

Increased Thermal Protection

Our Low-E4® SmartSun™ glass features an airtight seal, impervious to the entry of outside air around the panes, for maximum insulation from heat and sound transfer. In addition, the panes are optimally separated with a patented low conductivity spacer and filled with a blend of argon gas to further reduce thermal transfer. These features make High Performance™ Low-E4® SmartSun™ glass 70% more efficient than ordinary dual-pane glass in the summer and 45% more efficient than its counterpart during the winter. This can cut your energy spending by up to 25% depending on where you live. **

**A study comparing Low-E4® SmartSun™ glass to ordinary dual pane glass revealed a 25% savings on cooling bills and 10% savings on heating in identical homes. Savings may vary.

Keeps UV Rays Outside

High Performance™ Low-E4® SmartSun™ glass works much like sun block lotion to reflect ultraviolet (UV) rays that can fade fabric coloration and damage furniture. Ordinary dual-pane glass lets as much as 63% of UV rays enter the room. High Performance™ Low-E4® SmartSun™ glass is comprised of 11 microscopic layered coatings that cut UV transmission down to just 5%, while retaining the clarity or color of the light that enters your house.

Reduces Sound Penetration

Sound penetration is also significantly reduced when compared to single and double pane glass of other makers.

Standard Feature

Every single Renewal by Andersen of Central NC® window selection comes standard with our Low-E4® SmartSun™ glass, and the technology is exclusive to Andersen® windows and doors.

*On exterior surface when activated by sunlight.
