Casement windows have long been favoured by homeowners and industry professionals due to their contrasting design and level of security. Being able to outwardly open your windows with the turn of a crank, gaining access to the outside world – and exceptionally generous airflow – as well as an unobstructed view, are all winning qualities that make them one of the most popular window styles. 

Whether you’re incorporating them into the operation of your bay window, or simply looking for increased ventilation over your kitchen sink, Casement Windows are sure to please even the most discerning homeowner.  

You may be thinking, how can a window that opens fully be energy-efficient? Bearing in mind that these types of windows are designed to firmly seal into place, and efficiency is naturally within their design, a few factors make them even more efficient than their counterparts:
 

• Energy Star Certification
  If your window bears the Energy Star label, chances are, you have an expertly crafted window that applies the highest manufacturing and material standards.
• Gas Fills
  When inert gas, like Argon and Krypton, is inserted between the panes of glass, hot and cold exterior temperatures have difficulty passing through the window. 
• Additional Panes of Glass
  When introducing an additional pane of glass, whether it be double or triple, you’re adding an extra layer of protection from the exterior heat, humidity, wind or frost. 
• Low-E Glass Coatings
  Low emittance coatings were developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted. It’s an invisible layer that during the winter months reflects heat back inside, and the reverse during the summer, similar to that of a thermos.
