Awning Windows

Like casement windows, awning windows open to the outside of the home, however, they open with a top hinge rather than a side hinge. These windows are opened with a crank handle making them very easy to operate. The handle also folds neatly into place along the bottom of the window when not in use to provide clean lines. The large glass surface of awning windows provides a clear, unobstructed view of the outside of your home, even when the window is open. Their awning effect when the window is open means that you can still enjoy fresh air in your home during light rain. Awning windows are perfect above the kitchen sink—they are easier to operate than side sliding windows and double-hung windows, which require additional strength to open when you have to reach across the counter.


UPVC frames and sashes

UPVC (Unplasticized Polyvinyl Chloride) is the premium choice for vinyl window manufacturing and the only vinyl used by Centennial.

  • Centennial’s unique formula resists damage from ultraviolet radiation
  • UPVC is a low-conductive material, making it more energy efficient than aluminum

Preserve the energy efficiency of your windows for as long as you own your home.

Centennial white colour

Soft and neutral, Centennial White blends seamlessly into your existing decor.

  • Designed exclusively for Centennial
  • Eliminates the stark, arctic white tone of many vinyl windows

Match your windows to any interior or exterior colour you choose.

Argon gas

The inert gas, argon, is used to fill Centennial’s double-glazed sealed glass units.

  • Colourless and odourless
  • Heavier than air

Argon improves the energy efficiency of your windows by slowing heat transfer through the glass.

Fusion welded corners

All corners of Centennial windows are fusion welded to transform the weakest point of the window into the strongest.

  • Eliminates the need for adhesives, screws, and staples to hold the window together
  • Creates one solid piece of vinyl

Increase the strength of your windows and eliminate drafts, leaks, and corrosion.

Super Spacer

Super Spacer is a non-metallic, silicone rubber material used in both double- and triple-glazed windows.

  • Separates the pieces of glass in sealed units
  • Allows the glass to flex

Preserve the integrity of your sealed unit and resist glass fractures.

Hot melt butyl

Hot melt butyl is a flexible material used to seal glass units.

  • Keeps argon gas inside double-glazed units
  • Applied after super spacer

Create an impermeable seal for your sealed glass units.

Our salesperson, Brian, was friendly, polite, courteous, and very well-informed. After a quick tour through the house to see what we needed, he explained the process of getting new windows, warranties, pricing, installation, and more. We purchased five large windows. The installation team showed up on time and quickly went to work. They were neat and very polite. If this same commitment to customer service remains throughout my warranty coverage, I couldn’t be happier. The overall experience was professional, honest, and pleasant.

How many years do awning windows last?

If you’re replacing your awning windows with high-quality vinyl products that are installed by industry professionals, they should last a lifetime. It’s important to remember that not all vinyl windows are the same and that even the highest quality windows will only perform to their promised standards if they’re installed properly. At Centennial, our windows and the installation are backed by our No Fine Print warranty that lasts for as long as you own your home. The warranty is also transferrable to new homeowners should you choose to sell your home within ten years of purchasing from us.

When should I use an awning window?

Awning windows work well in situations where you need the increased air tightness and energy efficiency of casement windows, but your opening is wider than it is tall. The perfect application for an awning window is above your kitchen sink so you can easily open it using the crank handle. This window style is much easier to operate in comparison to traditional side sliding windows and double-hung windows, which require lifting and pulling.

Can I install an awning window in the basement?

Awning windows can be installed in basements if there is adequate clearance on the outside of the home. However, awnings should not be used for egress windows (a window with enough space for entry or exit in case of an emergency). The challenge with awning windows for egress is that they do not provide adequate space for an adult to exit through the window because of the operating arm. If egress is required, side sliding windows and casement windows are better choices.
