New Vinyl Windows Refresh Littleton Home with Style and Efficiency

After more than two decades in their Littleton home, this family decided it was time to address a long-standing issue: their original builder-grade windows were no longer performing. The seals had failed, the screens were worn and the windows had visibly degraded. "We purchased our new home in 1999," shared the homeowners. "After 25 years, the windows and screens the builder installed had lost their seal and luster."

Looking for a trusted brand and high-quality product, they turned to Pella Windows & Doors of Northern Colorado. Our team guided them through the process, helping them select durable, high-efficiency vinyl windows that matched their goals for comfort, performance and aesthetics.

Pella 250 Series vinyl windows are engineered to stand up to the elements, especially in high-altitude climates like Colorado. These windows are up to 52% stronger than ordinary vinyl, with a multichambered frame design that improves thermal efficiency and resists warping.⁸

The windows installed on this home featured dual-pane SunDefense™ Low-E glass with insulating argon gas—a smart choice for regulating indoor temperatures and minimizing heat gain, even during Colorado’s sunny winters.

Foam insulation within the frames added another layer of protection against drafts and noise, while the InView™ screens provided a clearer view with better airflow. With a U-Factor as low as 0.25 and a Solar Heat Gain Coefficient (SHGC) of 0.20 or lower, these windows met stringent energy performance standards and helped reduce the home’s overall energy load.

The transformation at the front of the home is immediately noticeable. With clean white frames and traditional grilles between-the-glass, the new windows add architectural definition while maintaining the classic look the homeowners wanted to preserve. From the living room to the master bedroom, multiple window configurations were designed to maximize light and visibility without compromising insulation.

The homeowners appreciated not only the quality of the products but also the ease of the overall experience. "Pella's estimate was comparative considering the quality and design of their product," said the couple. "The timeline of measuring, ordering and installation of the new replacements were timely. The employees were respectful, efficient and professional. The clean-up and disposal of old windows was done the same day. The whole experience was stressless and pleasant."

Ease of use was also a factor in their decision. The installed single-hung windows feature cam-action locks and tilt-in sashes for easy cleaning—ideal for long-term living in a two-story home. Plus, the added insulation helps improve interior comfort and reduce exterior noise, creating a more serene environment throughout the year.

Whether standing up to mountain winds, blocking summer heat or adding lasting beauty to the home’s exterior, these Pella 250 Series windows delivered on every front. The family now enjoys a refreshed home with better performance and peace of mind for years to come.
