Wilserv Corporation Information

Wilserv is proud to offer Great Lakes Windows®. Great Lakes Window is one of the oldest manufacturers of premium vinyl replacement windows in the United States. Great Lakes Window has pioneered some of the best ideas in replacement windows including their patented R-Core insulation, Pinch Fusion Welding, and High Performance glass options like Maxuus 7.6, Maxuus 10, HP2 and HP Max. Today, Great Lakes Window is a manufacturer dedicated to providing homeowners with windows and doors designed to meet your lifestyle while helping to conserve our nation's resources. With a history of innovation and relentless commitment to quality, Great Lakes Window has maintained a reputation for manufacturing world-class products. Their quality has been tested and certified by independent industry organizations including the Window & Door Manufacturers Association and the National Fenestration Rating Council. Not to mention that our units with optional multilayer, vacuum-deposition, soft-coat Low-E glass have earned the ENERGY STAR®. That means they've met the strict energy efficiency guidelines set by the U.S. Environmental Protection Agency and the U.S. Department of Energy. A variety of standard and optional glass packages are available to consumers depending on the window and the manufacturer. Window units that are gas-filled (argon or krypton), Low-E (Emissivity) glass, double and/or triple pane all provide more energy efficiency than single-pane ordinary insulated glass. In determining that value to you as a consumer, you need to decide how much or how little air infiltration and energy efficiency you desire from your windows. Air between the panes of insulating gas can be replaced with high-density Argon or Krypton gas. This process provides windows with a both increased energy efficiency and increasing sound deadening properties. Both Argon and Krypton are safe, odorless, colorless gases that occur naturally in our atmosphere. But, because of their density, heat and cold do not pass through these gases as easily as through air. When Argon or Krypton gas is used in an insulated glass system with a vacuum deposition (sputter) coat Low E glass, it creates one of the most energy efficient windows you can buy. There are two major types of Low-E (the ‘E' stands for emissivity) glass: hard-coat (pyrolitic) and vacuum-deposition (sputter). Both types block radiant heat, keeping summer's heat outside and winter's heat inside. And both block the sun's rays to some degree. But windows made with multi-layer, vacuum deposition (sputter coat) Low-E glass have much better visual clarity. With this type of glass you have very little haze factor which provides almost the same clarity as clear ‘uncoated' glass. Click Here to request a Free Energy Smart Home Audit.
