Bay Windows

Bay Replacement Windows

Bay window formed as the exterior expression of a bay within a structure, a bay in this context being an interior recess made by the outward projection of a wall. The purpose of a bay window is actually to admit more light than would a window flush with the wall line.


Bay window is a common term for all protruding window constructions, irrespective of height. The most popular interior angles are 90, 135 and 150 degrees, though triangular bays formed of two windows set at 120 degrees may be found.

Most are polygonal or square; when curved they’re called bow windows.

A bay window having a flat front and angled sides is called canted.

A bay window supported by a bracket, corbel or similar is called an oriel window.

Bay windows project outward from the right or left side of the home. They’re made up of a central window and two side windows. The central window is mostly fixed, and parallel to the present wall. The side windows are set at a 30, 45, 60, or 90 angle. They¬† frequently have casements or double-hung styles and are either stationary or operating. Bay windows have a deep sill area that’s commonly used as a display for plants. Whether you choose to set up a bay window in your master bedroom, kitchen, or living room, there are several advantages and few disadvantages to take into account.

Benefits Of Bay Windows

Add Value To The House. Bay windows are often chosen for their aesthetic appeal. From the external part, the shimmering glass brings the home a fresh, modern appearance. On the interior, the style looks refined and creates a feeling of additional space. Aesthetic appeal and increased square footage add to the resale value of your home.

Allow Natural Light To Enter. Bay windows have panoramic views, so they will allow more natural light to enter from several directions.

Good Ventilation. Because bay windows provide the choice of having two operating windows, the homeowner and guests may love a pleasant breeze from two directions instead of only one.

Versatility. Bay windows are found in almost any room in Victorian homes, but they’re also a popular enhancement for modern dwellings. They could be installed anywhere, but bay windows are popular in the kitchens and living rooms of contemporary dwellings. The space around the window allows for a reading nook or banquette style seating.

Bow windows and bay windows are sometimes confused, based on the names. Although bow and bay windows have the same effect, they are a little different in building or construction. Bay windows have three parts, while bow windows have four or more window units joined together to form an arc.


Allow natural light to enter. This is both an advantage and a disadvantage. Bay windows allow ample light to enter, so it’s vital to purchase windows with excellent ratings against solar heat gain.
