Replace Your Windows

According to the EPA, Energy Star-qualified windows can save the typical household $125-$450 per year in energy costs when replacing single-pane windows and $25-$110 per year when replacing double-pane clear-glass windows.

What makes a window energy-efficient?

-- Improved frame materials such as wood composites, vinyl, and fiberglass reduce heat transfer and improve insulation.
-- Low-E glass with special coatings reflects infrared light, keeping out summer heat.
-- Gases between the panes, such as argon or krypton, insulate better than regular air.
-- Multiple panes of glass with air or gas in between insulate better than a single pane.
-- Warm-edge spacers keep a window's panes the correct distance apart to reduce heat flow and prevent condensation.
