    We just had our windows installed Thursday on the new house. I took a picture of the tag on the window to see if anybody knew what they stood for, and if they are good, average, or low. Any help is appreciated!

    U-Factor measures how well a product prevents heat from
    escaping a home or building. U-Factor ratings generally fall
    between 0.20 and 1.20. The lower the U-Factor, the better
    a product is at keeping heat in. U-Factor is particularly
    important during the winter heating season.

    Solar Heat Gain Coefficient (SHGC) measures how well a
    product blocks heat from the sun. SHGC is expressed as a
    number between 0 and 1. The lower the SHGC, the better
    a product is at blocking unwanted heat gain. Blocking solar
    heat gain is particularly important during the summer
    cooling season.

    Visible Transmittance (VT) measures how much light
    comes through a product. VT is expressed as a number
    between 0 and 1. The higher the VT, the higher the
    potential for daylighting.

    Those numbers indicate each window is chipped and pulley'd.

    DON'T TINT THE WINDOWS!!!! at least before talking with the manufacturer. They will immediately void your warrany. The tinting can create heat within the window (which is filled with a "Low E" gas - argon i believe)....the seals are not designed for the added heat.

    just talk to the manufacturer before you do it....they can give you a good explanation.

    Agreed. You can get room darkener shades instead. They come manufactured with foil linings.

    That was my first thought when I saw the stickers. Amazing how they have an affect on the rest of the US. I'll definitely give the manufacturer a call prior to doing the windows. I didn't even think about that. :read:
