Key Differences Between Wonder And Window World Windows

Frame Materials

One of the biggest differences between Wonder Windows and Window World is the variety of frame materials available.

Wonder Windows offers windows made from:

  • Vinyl – Affordable, low-maintenance, and energy-efficient. Available in white or beige.
  • Aluminum – Strong and durable. Ideal for coastal climates. Needs frequent repainting.
  • Wood – Beautiful natural appearance. Requires staining/painting every 2-5 years.
  • Fiberglass – Low maintenance like vinyl. More strength than vinyl. Expensive.

Window World sells windows with these frame types:

  • Vinyl – Budget-friendly, long-lasting, easy to clean. Offered in white or clay.
  • Fiberglass – Very durable and dent-resistant. Won’t expand/contract. Higher cost.
  • Wood – Timeless look, custom staining options. Requires frequent refinishing.

Wonder Windows gives you more choices if you want metal or wood frames. Window World is limited to vinyl and fiberglass.

Window Styles

Both Wonder Windows and Window World provide all the most popular window styles:

  • Single/Double-hung – Vertical sliding sash(es). Easy cleaning. No space needed for opening.
  • Sliders – Horizontal sliding sash. Smooth and quiet operation. Compact footprint.
  • Casements – Side-hinged outward opening. Maximize airflow. Crank operation.
  • Awnings – Outward-opening top-hinged windows. Keep raindrops out when open.
  • Fixed/Picture – Non-opening glass panels. Bring in light and views.

You’ll have access to the same operating styles with either brand. The main difference is Wonder Windows also offers custom shapes like triangles, trapezoids, and arches. Window World just provides rectangular windows.

Energy Efficiency

Replacing old drafty windows with new energy efficient models is one of the best ways to reduce energy costs.

But how do Wonder Windows and Window World compare?

Both brands offer dual-pane insulated glass with optimal air space thickness and low-E coatings that reflect heat.

This combination blocks heat loss in winter and heat gain in summer.

They also fill the air space between panes with argon gas. This further slows the conduction and convection of heat/cold through the glass.

As a result, you can expect similar energy savings from the standard windows of either manufacturer.

However, Wonder Windows takes efficiency a step further with options like:

  • Triple-pane glass – Three panes provide even more insulation. Ideal for cold climates.
  • Krypton gas – More expensive but more effective than argon fill.
  • Thermal spacers – Reduce heat flow at the edge of the glass panes.

So if maximizing energy performance is your top priority, Wonder Windows gives you more available upgrades.

Glass Options

The types of specialty glass available is another area where Wonder Windows shines over Window World in terms of selection.

Wonder Windows offers:

  • Low-maintenance vinyl glass in a variety of colors/finishes
  • Obscure glass for privacy
  • Laminated glass for security and sound dampening
  • Tempered glass for increased strength
  • Impact-resistant glass for hurricane-prone regions

Window World provides more limited choices:

  • Standard double-pane clear glass
  • Obscure glass for bathrooms
  • Tempered glass where required by code

So if tinted, decorative, or security glass is on your must-have list, Wonder Windows is the way to go.

Frame Colors

For traditional white windows, you’ll have plenty of options with both brands. But what about other hues?

The vinyl frames from Window World come in just two neutral colors:

  • White
  • Clay

Wonder Windows vinyl frames are available in these diverse shades:

  • White
  • Beige
  • Gray
  • Tan
  • Green
  • Brown
  • Brick red
  • Coastal blue

So if you want to match existing trim or make a bold color statement, Wonder Windows offers more vinyl finish choices.

For custom colors, Window World provides vinyl overlay trims in 16 color options. Wonder Windows allows custom-color painting of aluminum-clad windows.

Installation Process

Replacing all the windows in your home is a major project best left to the professionals.

Here’s how the installation process compares:

Wonder Windows are installed by certified professional installers employed by the company.

They take care of all aspects from permit paperwork to the final cleanup.

Window World follows a different model. They contract with local independent installers across their territories. The quality of workmanship can vary more than with in-house staff.

For both brands, you can expect a typical window replacement to take 2-3 days. Crews take care to protect your interiors and contain dust and debris. Damages should be repaired as part of the installation service.


The warranty coverage provides valuable peace of mind that your investment will stand the test of time. Let’s compare what’s offered:

Wonder Windows provides a limited lifetime warranty on vinyl and hardware. It guarantees these components will be free of defects.

For the insulated glass units, Wonder Windows offers 20 years of coverage against seal failure causing fogging.

Window World warranties all components including the frame, glass, and hardware for as long as you own your home. This is one of the strongest window warranties available.

So Window World wins when it comes to overall warranty length and coverage. But Wonder Windows still provides reassurance with decades of protection.
