Bow Windows


Bow windows first came into popular use in the eighteenth century in the United Kingdom. To this day this type of window remains a popular and beautiful choice for any household.

Gold Leaf’s bow windows are Energy Star certified, giving you the ultimate peace of mind. You can rest assured knowing your home has windows designed to withstand the harshest temperatures that Mother Nature can throw your way. As a great alternative to a simple double pane window, Gold Leaf proudly offers EcoSmart triple pane glass and foam filled frames as an option in all our casement window styles.

  • Heavy duty structure and design
  • Gentle angles offer a beautiful arch and view of the outdoors
  • Offers an elegant appearance.

Similar to bay windows, bow windows offer a breathtaking view of the outdoors. The main difference between these two types of windows, which are commonly confused for one another, is that bow windows have a round shape, instead of the standard square design.

Bow windows do not have corners that protrude on the exterior of your home. As a result, you will have a window that offers a seamless and elegant appearance from the curb. The overall goal of this window style is to create the illusion of a curved wall. This is accomplished by combining multiple casement windows, typically four to six, side by side. When done properly, the window has gentle angles, which successfully extend into an arch.

With advanced structural design and sealed glass panes to help protect against condensation, you can rest assured knowing that bow windows from Gold Leaf will beautify and protect your home. We make it our mission to ensure your home is warm, dry and energy efficient with all of our window offerings, all proudly made in Canada!

All of our windows and doors have the Energy Star seal and provide maximum home insulation. Our vinyl windows are more energy-efficient, fire-resistant and modern than wooden or aluminum windows. Canadian-made windows and doors from Gold Leaf feature advanced structural designs, high quality sealing systems and stunning good looks.

Gold Leaf Windows & Doors also offers insulated spacers within the sealed glass between window panes to help protect against condensation. We apply low emissive coatings to all our window surfaces to protect against heat loss. At Gold Leaf, we make sure your home is warm, dry, energy-efficient and beautiful for years to come.
