Insulating Performance

Keeping Your Home Comfortable and Energy Efficient
Insulation performance is measured to determine how effectively a window keeps heat in a home. Better insulation in windows means lower energy costs, and just as important, improved comfort on cold winter days. Insulation performance is measured in U factors.

The U Factor is a measure of resistance to heat flow. A lower U Value means better insulation performance. Triple glazed windows with trigon gas are truly energy efficient, offering glass that is two, three or almost four times more energy efficient than typical dual pane windows. This superior performance will make your home more energy efficient and comfortable. The chart below compares the insulating performance of different glazing products.

You should Select a Lower U Value Glazing if:

• Reducing heating costs is a factor in your design planning. Your home has large areas of glass. Improving the insulating value of your windows may be necessary to comply with local energy codes.
• You sit near your windows in the winter or summer.
