How to Choose the Right Glass Package for Your Windows

When selecting the ideal replacement windows for your home, the glass package should be one of the primary considerations. Windows are roughly 80% glass, which means the glass system you choose is crucial for energy efficiency, climate comfort, and year-round savings. 

Understanding the Basics

Reducing energy loss is often a top reason for investing in replacement windows. This is where a high-performance, low-emissivity (Low-E) insulated glass package, like BarrierXP PriME, comes into play. It’s a game-changer for homeowners looking to enhance their energy savings.

BarrierXP PriME provides homeowners with multi-layered Low-E glass, argon gas, and an innovative Intercept Warm-Edge Spacer System. Consider these benefits to determine if BarrierXP PriME is the right glass package for your Gentek windows:


  1. Exceptional Energy Efficiency: BarrierXP PriME is proven to be far more energy efficient than ordinary clear glass units, helping to reduce energy consumption and lower utility bills.
  2. U-Factor Matters: When comparing glass package performance, pay close attention to the U-Factor. The lower the U-Factor, the less energy you’ll need to heat your home. This factor is particularly crucial in colder climates where keeping the warmth inside is essential.

  3. Solar Heat Gain Coefficient (SHGC): In warmer regions, the SHGC is a key metric to consider. The lower the SHGC, the more you’ll conserve on air-conditioning costs. This is particularly important for maintaining a comfortable indoor environment during hot summers.

BarrierXP Pri
ME is available with Gentek Signature Elite and 80 Series windows and Sanctuary sliding patio doors.  

Before choosing new windows, consult a professional to help you determine the best glass package to meet the ENERGY STAR requirements for your home and climate zone.
