The Most Efficient Window
Xtreme windows combine several high-tech coatings, an argon gas insulation barrier and a number of manufacturing details that achieve both a beautiful clear glass look while delivering incredible insulating performance. The chart below shows how they work. Don’t be fooled by other claims – insist on seeing the NFRC rating sticker and compare (enlarge our actual stickers at right) – you just won’t find a lower U-Factor! Xtreme-5 exceeds all ENERGY STAR qualifications and is eligible for a federal tax credit.
