Energy Savings 101: How Modern Windows Cut Heating & Cooling Costs by 25%

## The Thermodynamics of Window Heat Loss and Gain To understand why modern replacement windows lower your electric and gas bills, you must understand the three modes of thermal energy transfer: 1. **Conduction:** Heat traveling directly through solid materials (glass panes, metal spacers, and frame jambs). 2. **Convection:** Air movement between glass panes and through perimeter frame gaps. 3. **Radiation:** Electromagnetic infrared energy radiating from the sun or warm indoor furniture through the glass. ### How High-Performance Windows Counter All 3 Transfer Modes: - **Dual/Triple Glazing with Argon Gas (Counters Conduction & Convection):** Argon gas is 38% denser than air, creating a sluggish thermal barrier that drastically slows conductive heat transfer. - **Spectrally Selective Low-E Coatings (Counters Radiation):** Reflects long-wave infrared heat back into your living room during winter and blocks short-wave solar heat during summer. - **AAMA-Certified Weatherseals (Counters Air Leakage):** Seals perimeter sashes against wind-driven air infiltration.
