Much more efficient than single-pane, it can be improved further with heat-reflective low-e coatings and by filling the space between the glass sheets with a denser-than-air gas, such as krypton or argon. With today’s glass, called glazing, you can get more insulation and added security, and can save time and money on window washing. Vintage single-pane “wavy” glass can’t be beat for character, but it provides little protection against the heat and cold.

A word of caution: Not all Energy Star windows are shoe-ins for the credit.
Save the “qualification statement” from the manufacturer and your receipts. The credit applies only to window costs, not installation. Windows installed in 20 qualify if they have an NFRC-certified U-factor and an SHGC of 0.30 or less. Some labels also rate Air Leakage (look for 0.30 or lower) and Condensation Resistance (the higher the number, the better).įederal tax credits can cut the cost of new energy-efficient windows by 30 percent, up to $1,500 per household. A lower VT limits glare but can slightly darken rooms. Glazing with a VT of 0.60 or more looks clear. Tells how much light passes through 0 is opaque, 1 is transparent. The lower the number, the less heat gets in. Measures how well glazing blocks the sun’s heat, on a scale of 0 to 1. The smaller the number, the better the performance in both cold and hot climates. Measures how well a window stops heat flow, on a scale of 0.10 to 1.20. The shaded portions of the accompanying map show where the window meets regional Energy Star performance criteria. Computer simulations create the key numbers for each window

Replacement Options: Full FrameĬomparing window performance is easy, thanks to labels from the National Fenestration Rating Council (NFRC). Adding interior storms made them as weathertight as new units. Pictured: Rather than replace these 18th-century windows, TOH master carpenter Norm Abram restored them to like-new condition. Is a sash hard to open or will it not stay open? Those old windows from the weight-and-pulley era are easy to fix, but sashes with tubular-balance hardware from the 1950s, ’60s, and ’70s may not be worth saving.Ī 19th-century Italianate fitted with modern replacement casements, for instance, will have infinitely more curb appeal with new wood double-hungs that match the look of the original windows. The window needs a new sash, at the least, if not entire replacement. When the perimeter seal on a double-glazed window fails, the condensation that collects between the panes of glass spoils the view and reduces energy efficiency. Small pockets of decay can be scraped out and filled, but if the sill and jambs are severely compromised, there’s no saving them. Start shopping for replacements when the following problems crop up: Similar to shown: Jeld-Wen Custom Wood Anatomy of a Double-Hung If new windows are in your future, this is one story you don’t want to miss.
