Zen Windows offers replacement windows that match the architecture of your home as well as your personal style and taste. Browse our vast selection of replacement window styles and high-quality vinyl materials custom-manufactured for a perfect fit.
Our windows come in three lines, with each available in various sizes and shapes as you can see below. These “good, better, best” lines are:
- Karma: A good option. Our Karma windows come standard with the Low-E Plus glass system, which features single-strength glass, a high-performance Low-E coating, and argon gas—a blend of technologies that will provide excellent energy efficiency. If you wish to upgrade, Zen offers practically endless possibilities for various glass, spacer, and Low-E combinations. Karma also features the Intercept® warm-edge spacer and sealant system, which is fully automated for condensation resistance and seal integrity.
- Nirvana: A better option. Our Nirvana windows come standard with the Low-E Plus glass system with double-strength glass (versus the single-strength of Karma). Nirvana has the same energy-efficient features as Karma plus Comfort Foam in the frame for excellent insulation to improve the window’s thermal effectiveness. Nirvana also comes with the Intercept® warm-edge spacer and sealant system.
- Lotus: Our best option. Our Lotus windows are triple-paned, which makes them our most energy-efficient windows. They come standard with the Ultra S™ glass system, which features double-strength glass, two high-performance Low-E coatings, and argon gas—a combination that will provide the best possible thermal performance. Lotus also features the Super Spacer® metal-free, warm-edge sealing system, which provides optimal reduction of heat and cold transfer around the glass perimeter.
All three window styles have an integral lift rail with a comfortable, ergonomic design that is significantly stronger and more durable than snap-in lift rails. They all feature the Certa-Force™ balance system, which provides smooth and easy operation of double hung windows and never needs lubrication or adjustment. Upgrades and customizations are available for all styles.
