4 Tips for Choosing Energy-Efficient Windows

Window replacement is a major investment. These four factors ensure you get performance, beauty, and value.

1. Frame Material

Vinyl, fiberglass, composite, and clad-wood outperform aluminum and old wood in insulation and maintenance.

2. Glass Package

Low-E double-pane with argon fill is the sweet spot. Triple-pane adds cost with diminishing returns in mild climates.

3. Design for Function and Style

Operable windows (casement, double-hung) allow ventilation. Fixed picture windows maximize efficiency but no airflow. Match your home's architecture.

4. Professional Installation

Flashing, air sealing, and proper shimming are non-negotiable. The best window fails if installed poorly. Choose certified installers with workmanship warranties.
