Explore our most frequently asked questions to learn more about aluminium bay & bow windows and their features, lifespan, and advantages.

While aluminium bay and bow windows are both similar in that they protrude from the wall, the shape and panelling are the key differences. Bay windows tend to have three panels, giving a more angular appearance, while bow windows have a minimum of four or five.

Appearing almost circular in nature, bow windows can go around corners and tend to let in more natural light. Bay windows can extend the interior space. There are advantages to both, whether your focus is on space or style. Bay windows are generally considered more contemporary in design while bow windows fit a traditional aesthetic.

Aluminium is ideal for bay window replacements thanks to its durability and energy efficiency. With a longer life expectancy than uPVC, aluminium is weatherproof and secure. 

Every Atlas Aluminium bay window is thermally broken, which helps to insulate homes and keep your energy bills low. For a beautiful, customisable aesthetic that lasts for decades, aluminium provides a true return on investment.
