It's vital to choose the best kind
of replacement window glass for your climate. The NFRC label on a window includes
information about the glass and every contractor or window retailer uses this
label to rate a window. This label will tell you how well your window would be,
both energy efficient wise and how well it will hold up in the long run.
- Double-paned (double-glazed) windows have two layered panes of glass. The
air in the space between the panes serves as insulation. All single pane
windows are a thing of the past now.
- Triple-glazed windows
have three layered panes and provide even better insulation.
- Gas-filled
windows are double- or triple-paned and have a gas like argon or
krypton filling the space between the panes of glass; the gas provides
better insulation than just a layer of air does, because the gas is
heavier than air. The NFRC label will list what type of gas in used for
that particular window.
- Warm-edge spacers (sometimes
called warm-edge technology) hold the panes of glass in a double-
or triple-paned window apart. They are made of a material that reduces
heat transfer and improves insulation. Foam is sometimes used as
insulation as well.
- Low-E (low-emissivity) glass is coated with a transparent metal film that
reflects heat. Low-E coatings reflect radiant heat off the inside of the
windows and back into the house to help keep it warm in the winter. Most
low-E coatings also reflect some of the sun's heat off the outside of the
windows, limiting how much of it enters the house.
- High-performance glazing is glass that has several features designed to make it
more energy efficient, such as two or three low-E gas-filled panes with
warm-edge spacers.
- Visible transmittance measures how much visible light comes through a window on a
scale of 0 to 1.The higher the number, the more visible light you'll receive.
You can find the (VT) on the NFRC label.
