Update or Replace Existing Windows

Determining whether to update or replace your home windows for energy efficiency depends on their condition and age.

Windows less than twenty years old and without damage may benefit from cost-effective upgrades to enhance energy savings. Check for drafts and consider solutions like caulking or weather stripping to restore seals. Adding blackout curtains or protective films can further improve efficiency.

If your windows are showing signs of age or damage such as frequent drafts, persistent condensation, or increased energy bills during extreme weather, it may be time for a window replacement in Raleigh. Renewal by Andersen offers customizable solutions, ensuring your new windows fit perfectly and provide optimal insulation with advanced glass options chosen for Raleigh’s climate.

Window Frames

Choose insulated windows with Renewal by Andersen’s Fibrex® material. This exclusive composite combines the strength and insulating properties of wood with the low maintenance benefits of vinyl. Fibrex® material is resistant to cracking, pitting, corrosion, and rotting, ensuring long-lasting performance without the need for painting.

Fibrex® material is specifically engineered to withstand extreme climates, making it ideal for cities like Raleigh that experience diverse weather conditions throughout the year.

Energy-Efficient Glass

Energy-efficient glass plays a crucial role in maintaining a comfortable indoor temperature year-round. Renewal by Andersen offers a range of glass options tailored to different climate needs. Our High-Performance Low-E4® glass, for instance, is designed to be 47% more energy efficient in winter compared to standard dual-pane glass. This makes it particularly beneficial for Raleigh, where winters can be chilly with occasional snowfall.

In addition to its winter benefits, High-Performance Low-E4® glass helps manage heat during the summer, ensuring your home stays cool even during hot days. Despite Raleigh’s humid, hot summer temperatures, efficient glass helps reduce cooling costs and enhances overall comfort.

Our double-pane windows are filled with argon gas, further enhancing insulation alongside Fibrex® material. This combination is crucial for residents outside the city limits who may face more severe weather conditions, ensuring optimal energy efficiency and comfort throughout the year.

Operating Types

Choosing the right window style is essential to maximizing the efficiency of your windows. For a traditional-style home in Raleigh, consider double hung windows, which offer versatility and classic appeal. Alternatively, large picture windows can beautifully frame the natural beauty surrounding your home, bringing the outdoors in.

Renewal by Andersen ensures that all operational windows, such as double hung windows, are installed with meticulous attention to detail. Our priority is creating a draft-free environment while allowing for controlled ventilation when the weather permits. For stationary windows like picture windows, homeowners can enjoy expansive views without compromising on energy efficiency.
