About Our Casement Windows

WeatherMaster’s casement windows are designed for maximum energy efficiency. Our windows utilize the latest window innovations to insulate your home better, and they look incredible. Some of the features we incorporate include: 

  • Welded Frames/Sashes – Welded frames on casement windows eliminate gaps at the corners, which allow cold or hot air to enter the home. This feature ensures the best insulation from your replacement windows. 
  • Low-E Glass – Solar glass helps to limit solar heat gain, a problem in summer that can cause overheating, as well as a reflective barrier that works like a thermos bottle to lock in your home’s heat energy during winter.
  • Heavy-Duty Weather-Stripping – Our advanced weather-stripping creates a completely air-tight barrier, resulting in best-in-class insulation. 

Expert Installation. Proper installation is critical for maximum energy savings. Let us help you install your casement windows to achieve the best insulation and more significant energy savings. 

Why Choose Casement Windows? 

Casement windows are a popular alternative to double-hung windows. They commonly were chosen because of their ease-of-use, full ventilation ability, as well as their modern, clean look. Some reasons you might select casement windows include: 

  • Functionality – The crank-open feature makes this a popular choice. They’re great for any location that might be difficult to reach to open the window, e.g., over countertops, in tight spots, and basements.
  • Durability – Our vinyl casement windows have aluminum reinforcement. They aren’t hollow, which maximizes strength and rigidity.
  • Custom Options – Customize your casement windows to match your home’s aesthetic. Vinyl and fiberglass casement frames come in a variety of colors and with several hardware options.
  • Modern Look – Casement windows resemble picture windows, and they’re often installed without grills. They’re perfect for a more contemporary look on your home or commercial property.
  • Easy Cleaning – The interior and exterior surfaces of a casement window can be cleaned from inside the home. That makes them a popular choice for multi-story homes and properties.   

Should I Choose Casement Windows? 

There are many reasons that people love casement windows. From their ease of use to their sleek look, this type of window works excellent on all kinds of homes and properties. Some pros and cons include: 


  • Ease of Use – These windows tend to be easier to use than double-hung or slider windows. 
  • Sleek Look – Casement windows have the modern look of a picture window, with the option to open and allow in a breeze. Picture windows don’t open. 
  • Excellent Ventilation – Unlike double-hung windows, casement windows open entirely, resulting in better approximately twice the airflow. That’s one reason they’re great for bathrooms and kitchens. 
  • Energy Efficiency – Casements have tight seals, and lock in place when they’re closed. The harder the wind blows, the tighter they seal.  Because of this, they are one of the most efficient types of windows. 


  • Size Limitations – Casements typically can’t be hung side by side, and they also don’t tend to be very wide, due to the way they’re mounted. 
  • Not Compatible with A/C Units – Most casements aren’t designed to allow window A/C units.
