The Billy Ellis Window System
Featuring Award-winning EnergyCore® Technology
EnergyCore®
EnergyCore®
• The most energy efficient window ever.
• Innovative, patent pending, fusion insulated technology called AirCell.
• When assembled with high-performance triple pane window,
EnergyCore exceeds Energy Star requirements by 50%.
• EnergyCore window frame is 6x better than fiberglass,
4x better than rigid PVC and 3x better than wood.
AirCell™
AirCell™ Maximizes Savings
• Outperforms solid, hollow, and insulation-filled frames.
• Reduces heat loss transfer through thermally conductive materials.
• Tri-extrusion manufacturing process ensures that window frames
are fully insulated without internal voids.
• Window corners are fully weldable for strength and weather-tight performance.
Measuring Energy Performance
• The energy performance of a window is measured in several ways.
• K-Value measures thermal conductivity, or rather how much energy an insulating material loses.
In frames, a lower K-Value is better, because it means that the material reduces heat loss better.
• R-Value is a measurement of thermal efficiency and how well a material blocks the transference of energy.
Higher R-Values mean better insulating ability.
EnergyCore Facts
• When combined with the best glass and spacer system EnergyCore will:
– Improve window U-values (by up to 0.20Btu/hr/ft2/F)
– Save almost 8,000 of CO2 production.
– Save $1,000/yr. in energy costs for average home
• EnergyCore profiles are 100% recyclable.
• EnergyCore technology offers a direct benefit to the environment by
promoting vinyl recycling in order to reduce landfill waste.
