Window Styles

  • Double-hung windows: A go-to standard for homes, double-hung windows slide open from the top and bottom for more ventilation options.
  • Casement windows: Common and functional in any style of home, casement windows open and close via hand crank, hinging from one side of the frame.
  • Awning windows: Awning windows look like casement windows but are instead hinged at the top for a different exterior look when opened.
  • Special shape windows: Special shape windows are styled and sized to fit unique dimensions and odd spaces. They could be triangular, half-round, or another special shape best fit for your home’s style.
  • Bay windows: The window every homeowner dreams of! Three adjacent windows project from an exterior wall and add additional shelf or nook space inside, as well as more natural light.
  • Bow windows: Comparable to the bay window, bow windows have at least three or more joined windows for a more rounded shape projecting from the outside.
  • Round-top windows: Round-top windows have a graceful, curved arch at the top for an extra architectural touch. Commonly set above doors or other full-size windows.
  • Slider windows: Windows that slide open horizontally along a bottom track.
  • Garden windows: Garden windows are typically installed above a kitchen sink. They project from the house’s exterior and often have a little shelf space inside, which is great for plants.
  • Picture windows: Very large, stationary (they don’t open) windows that bring in lots of natural light. The most captivating picture windows make it hard to tell where the inside ends and the outside begins.

Window Materials

Vinyl windows are the gold standard for replacement windows when considering cost, quality, and options. With manufacturing and technology enhancements, high-quality vinyl windows deliver on longevity, design, and value. Benefits of vinyl windows include:

  • High durability and long life span that translates to exceptional overall value
  • Immunity or resistance to rot, pests, and weather
  • Highly energy-efficient for improved comfort and reduced energy costs
  • A wide range of design and color options
  • Low-maintenance, requiring no painting and minimal cleaning

Because there’s a difference between high-quality and low-quality vinyl windows, Zen Windows only sources high-quality vinyl windows from trusted manufacturers.

Energy-Efficient Windows

Energy-efficient windows have been shown to save 10%-30% on monthly heating and cooling costs. They eliminate drafts, extend the service life of your HVAC systems, and bring extra UV protection to prevent fading artwork, paint, carpet, and furniture.

You can order energy-efficient windows for our most popular window styles, including double-hung, picture, casement, slider, awning, bay, bow, and garden windows.

We offer these energy-efficient window brands to bring you the best quality, price, and design options:

  • Karma: Quality, everyday replacement windows with customizable configurations and flexible features that work well for any home. Notable construction features include Intercept® warm-edge spacers that create a reliable seal for energy-efficient performance and double-paned, standard low-E glass with argon gas insulation between the two glass layers.
  • Nirvana: The Nirvana line of windows is upgraded, offering all the Karma construction features plus double-strength glass for extra durability, insulation value, and energy efficiency.
  • Lotus: Top-of-the-line Lotus windows represent the pinnacle of our replacement window selection. Windows are triple-paned with double-strength glass for each of the three panes and double-coated low-E glass. For a performance bonus, Lotus windows offer the most advanced sealing system — the Super Spacer® metal-free, warm-edge seal.
