If you have the money and wall space to make a big impression, maybe invest in folding patio doors. These doors spread out across the back wall of your home and appear as multiple glass windows sitting side by side, but open accordion-style to let in the most air and sunlight while extending the living space. Typically, folding patio doors can have anywhere from 2-8 panels that move along a track. Generally, accordion-style doors are made with glass panels to create the look of windows across the wall. However, they can be made from any material. Some homeowners go the extra mile and have decorative glass installed on some or all of the panels to make for a great statement piece in their living space. If a homeowner wants to keep the design simple while having excellent privacy, they may opt for a frosted look instead.
