Windows are often the weakest thermal point in a wall. Choosing the right products has a real effect on comfort, energy use, and code compliance.
Understanding U-Factor
U-factor measures how well a window resists heat flow. A lower U-factor means less heat loss in winter, which is critical in the Massachusetts climate and contributes to a better HERS score.
Solar Heat Gain
The solar heat gain coefficient describes how much solar energy passes through the glass. Balancing this value helps manage summer cooling loads while still capturing useful winter warmth.
Installation Matters
Even the best window underperforms if it is installed poorly. Proper flashing and air sealing around the rough opening prevent leaks and water intrusion.
