Our Super Peak Performance™ triple-pane glass system is constructed of two lites of LoE2 Glass and one lite of clear glass. The two air spaces between the panes contain Krypton gas, a denser gas than even the popular Argon. What this means for you is the highest quality thermal barrier, as well as an insulator from outside noise. Super Spacer® Warm-Edge Technology seals the unit.
During the warm summer months the Super Peak's LoE2 coating repels sun rays and the heat they bring, keeping your home cool and comfortable and your energy costs down. As the Super Peak protects your home's interior from harmful UV rays, so too are your draperies, carpets and furniture safe from the sun's fading effects.
As the weather turns cold Super Peak Performance's LoE2 glass works to keep the heat in, once more catering to your comfort while maintaining energy savings. This is also where the Super Peak's Super Spacer performance truly shines. As opposed to a standard window's aluminum spacers, the Super Spacer's unique design and foam construction guarantees unparalleled thermal performance and longevity.
We are very pleased with our new windows and the service we received from Jon, our Sales Rep, and Jeff, the installer. Jon and Jeff are very professional and courteous. We purchased a total of 15 windows. We also had one window enlarged which required new framing for the new, larger, window. Our house was much cooler because of the new windows during the extreme heat wave we had in August. We look forward to our house being much warmer this winter. We recommend Alenco to anyone looking for a great company that sells and installs excellent windows.”
