What is a Bay window?

What is a Bay window?

Bay windows are shaped to protrude from buildings increasing the amount of light entering a room and also creating additional space.

A traditional design is a large central picture window and then two smaller windows on either side that are angled to connect the central window to the building. Bay windows can have more panes and also different shapes like an arc or rectangle.

Edwardian replica bay windows

case study

Edwardian replica bay windows

Homeowners of this particular property were unhappy with their original bay windows as they allowed draught to enter their home. This not only made their house very cold during winter months but was also not energy-efficient or environmentally considerate. They wanted to improve this without impacting history and changing the characteristics of the property, a dilemma of historic versus comfort.

Accoya approved manufacturers, Tony Birch Ltd, produced two near-perfect replica bay windows. Using Accoya which is thermally efficient, sustainable and great to work with, the team at Tony Birch has solved the homeowners dilemma. The new windows exceed modern building regulations, whilst achieving the traditional look, something that is not easy to achieve as high-performance windows usually require large timber sections.

Window styles

Accoya wood is very versatile, ideal for many different types of windows to suit any home.
