# Bay & bow windows

A bay or bow window projects out from the wall to pull in light from three directions and add a little usable depth to the room. It is the upgrade that turns a flat wall into the best spot in the house.

What it is

## Part window, part small addition.

A bay window combines three windows at angles; a bow uses four or more in a gentle curve. Either way you get more glass, more light, and a deep sill for a seat, plants, or display. These need a careful, well-supported install to look right and stay sealed, which is exactly what our own crews are for.

Best for: Living rooms, dining rooms, and any space that wants a focal point and more light.

How we do it

## The details that decide the difference.

01

### Light from three planes

Angled glass pulls daylight and a wider view into the room far beyond what a flat window offers.

02

### A deep, usable sill

The projection gives you a window seat, a plant ledge, or display space a standard window cannot.

03

### Supported and sealed right

We tie the unit into the wall, support the projection, and flash it so it performs as well as it looks.
