Introducing EnergyCore™ the Most Energy-Efficient
When it’s time for new windows in your home, you have
the opportunity to make your home more energy efficient, saving you
money on heating and cooling costs as you reduce your impact on the
While there are many choices, one stands out as the
most energy efficient window today: The EnergyCore Window. There are
many factors that influence how well a window performs, including
the frame material, number of “lites” or window panes, LowE glass
and the gasses and sealants between glass.
The EnergyCore Window is built with the most
innovative technologies essential to a window’s overall energy
performance. Combining superior frame technology with high
performance components such as triple-pane glass and superior
composite spacers, gives you the most energyefficient, cost-saving
window you can install in your home.
The energy performance of a window is measured in
several ways. First, 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.
