About the Harvey Shaped Windows
Windows come in all shapes and sizes. In fact, they come in so many shapes and sizes, we can't possible have a page for each one. Simply select the shape from the option to the right and indicate the approximate size by measuring the length and width from the widest and tallest part of the window. If you have multiple, different, shaped windows, simply add each individually to your cart. Our professional inspection/installer partners will make sure to get the measurements exact before you get your final price.
Every Harvey vinyl replacement window is custom manufactured, to our exact specifications, right here in New England.
The energy ratings assume two panes of Low-E glass (minimizes ultraviolet and infrared light) and Argon Gas (denser than air for extra insulation). Windows with grids will have slightly lower Solar and Transmittance numbers.
The lower the number, the better. To meet Energy Star requirements, windows must have a u-factor at or below 0.27.
The higher the number, the more light is transmitted. VT values typically range from 0.30 to 0.70.
The lower the number, the more it will help reduce the use of air conditioning and energy use. In cold climates, a higher SHGC is desirable to collect heat from sunlight. SHGC typically ranges from 0.25 to 0.80.
