EnergyCore™ Windows

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 environment. New windows also reduce outside noise and hot and cold rooms making your home all around more enjoyable.

While there are many choices, one stands out as the most energy efficient and sound reducing 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 AirCell™ frame technology with high performance components such as triple-pane glass and superior composite spacers, gives you the most energy efficient, cost-saving window you can install in your home.

Introducing EnergyCore™ the Most Energy-Efficient Window Ever.

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 environment.

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.

INNOVATIVE FRAME TECHNOLOGY

The AirCell™ frame window was created using a patent-pending fusioninsulated process. This unique manufacturing process, fully insulates the frame and adds structural integrity to the window.

Compared to other foam-filling processes that can leave voids, the fusion-insulated process eliminates all voids that can lead to energy loss.

In fact, compared to all other frame types, EnergyCore with AirCell is stronger and delivers superior energy performance. In comparisons, EnergyCore reduces energy loss (blocks thermal conductivity) six times better than fiberglass, four times better than vinyl and three times better than wood.

THE DURALITE WARM-EDGE System

In addition to a superior energy-efficient frame system, the EnergyCore Window uses the best spacer in its class.

Among the other high-performance components that make the EnergyCore Window the best in its class are the spacers that separate multiple panes of glass in the window’s construction.

Duralite™ next-generation spacer with warm-edge technology uses no metal. It substitutes metal with a unique laminated composite. As a result, Duralite reduces thermal conductivity up to 45 percent.

When compared with other spacers, Duralite offers the lowest U-Value rating, the best condensation resistance, and is the best energyefficient spacer system available.

Duralite spacers perform better in U-value tests than any other spacer.
