Gaia Windows is an Omaha based manufacturer of high quality, highly energy efficient fiberglass and uPVC windows.  They specialize in casement/awning and picture windows.  Their mission statement is to "provide the most energy efficient window at the best possible price."  Because of this they only offer casement series windows which provides far superior energy performance to horizontal sliders, single hungs, and double hungs.  Gaia offers a multitude of glass packages featuring Cardinal LowE-366 glass and Heat Mirror technology.  The windows are locally manufactured in Omaha, NE which helps LEED projects achieve points for locally sourced materials and it allows Gaia to sell the windows locally at a lower cost due to less transporation costs.  The windows feature unique upgrades such as grids between the glass, BetterView window screens and krypton gas fills.
