Lacina Siding & Windows, Inc. installs bay windows in Owatonna, Rochester, and Mankato homes. This type of window design creates expanded views and offers low-maintenance performance. Bay windows usually have three panels and a grid pattern but can be customized to achieve the look you want. They also protrude out from your home, creating a spacious window ledge. Bay windows look great in living rooms and formal dining rooms. Wood, white vinyl, or a combination of materials is available for the frame and easy turn crank handles open sections to allow air in.
