Bay Window Construction Components

Windows

• A bay window consists of three separate window panels. The main window component is typically the largest and is set out farther than the outer wall of the home. Two side window panels may be similar in size but are often smaller than the main window. The side windows often open to allow ventilation and air circulation through the window unit. These two side windows angle back from the main window to attach to the home's exterior wall. You are able to purchase the three window panels as one unit that is already constructed and ready to install or separate.

Roof

• Since the bay window sticks out beyond the exterior wall of the home, it needs a separate covering over the top. A small roof is typically installed as the cap of the bay window. An angled roof directs water off the bay window top to avoid damage or leaking. You are able to cover the roof with shingles or other roofing materials to make the bay window complement the existing exterior of your home.

Bracing

• Bracing is essential to keep the bay window attached to the home and to avoid eventual sagging due to the weight of the window. A steel cable system allows you to support the bay window from above with the cables being hidden within the window frame. Braces underneath the window on the exterior of the home are another option for supporting the weight of the bay window. The options available depend on the manufacturer of the window.

Finishing

• The finishing touches are the final components of the bay window construction process. Both interior and exterior finishing touches complete the project. On the inside of the home, the bay window receives trim and is painted or stained to match the existing woodwork. You also have the option of installing a window seat under the window. Decorative coverings and trim on the exterior of the bay window make it visually appealing from outside. The options for finishing pieces often vary depending on the type of bay window you use and the company that makes it.
