Knoxville Bifold Patio Doors

Connect Your Home to the Outdoors with Bifold Doors

Knoxville has the nation’s largest concentration of Victorian-style homes and has many homes listed on the national register of historic places. Fort Sanders, one of the oldest residential areas in Knoxville, has many admirably renovated historic homes intermixed with newer Victorian-, Bungalow-, and Craftsman-style homes.

Bifold patio doors match your home’s classic charm while giving you a more functional, open living space. With bifold doors, two or more glass door panels are hinged together and open up like an accordion to turn a glass wall into a wide entrance that seamlessly connects your indoor and outdoor entertaining areas.

Commonly known as: exterior bifold doors, folding patio doors, concertina doors, accordion doors, bifold patio doors

Popular Local Trends & Styles


  • Mid-century modern home Multi-Panel Bifold Patio Doors

    Knoxville is home to such an eclectic mix of architectural styles that homeowners covet the chance to stand apart from the crowd. To that end, bifold patio doors can be customized with up to 10 panels, depending on the needs and size of your space. You can also decide how you want the doors to function, either as folding door panels that travel to one side or part in the middle.

  • Victorian Style Victorian Style

    Fort Sanders is the oldest neighborhood in Knoxville, developed in the late-1800s. Some of the most notable homes are Victorians — a popular style throughout the whole city. Accordion-style patio doors with Victorian-style grilles can create a glass wall that matches your home’s classic charm while giving you a more functional, open living space.

  • traditional style homes Wooden Patio Doors

    Wood is the material of choice for patio doors in Eastern Tennessee because it blends just as easily into the fabric of historic homes as it does more modern styles. With the addition of grilles, wooden bifold patio doors can look like classic double French doors. For a more modern look, go with minimalist wood frames and clean, undivided glass panels.

  • integral light technology grilles Integral Light Technology® Grilles

    Enhance the architectural style of your home with bifold patio doors that incorporate grilles. Grilles provide the appearance of individual window panes, but Knoxville homeowners can take it a step further with Integral Light Technology® square profile grilles. These are permanently bonded to the inside and outside of the glass, offering an even more authentic look.

If you are looking to match trending styles as you update your home, consider coupling thin frames with modern hardware and full-panel glass. Renovators should look to more classic elements, like grilles and hardware finishes like rustic, bronze, or brass.

Eastern Tennessee Climate Recommendations


Knoxville and Chattanooga are both classified as temperate humid subtropical climates. Residents know to brace for hot and humid summers, but are also prepared to bunker down during the severe thunderstorms that frequently visit the area in the winter season. Wood bifold patio doors need additional protection for the seasonal shifts in temperature and precipitation.

Low-E Protection

Get year-round protection with Low-E insulating glass. The added protection helps provide balanced insulation from hot summers and moderate winters.

Durable Materials

Durable Materials

Ensure your home’s wooden bifold doors are prepared for the seasons. Wood patio doors with exterior aluminum cladding can help protect your home from the elements.

  •   What general maintenance is required for my Pella windows and patio doors?
    • Pella recommends you inspect your windows and patio doors at least annually as part of a home checkup. Maintenance can prolong the life of your Pella windows and doors and will help ensure maximum warranty coverage.

      As needed, clean, repaint or restain your windows and patio doors, and recaulk around them to help maintain optimal performance. Also, be sure to regularly check for leaks and improper drainage above or around vents and sprinkler systems that may subject your windows and patio doors to prolonged water exposure.

      Review the Maintenance section of the Pella Window and Patio Door Owner's Manual for additional details about how to properly maintain the interior and exterior of your Pella windows and patio doors.

  •   How do I choose the right paint or stain for my wood windows and doors?
    • Stained Wood Interior Finish – Pella strongly recommends the use of a good-quality pre-stain wood conditioner before staining Pella windows and patio doors to reduce the possibility of a blotchy-looking, uneven finish. Ask your paint or finishing professional to recommend a pre-stain wood conditioner, a stain and a finishing coat that are compatible.

      Painted Wood Interior Finish – The most important consideration to make when choosing your paint is good blocking resistance — the ability of a paint to resist sticking. Failure to use a high-quality paint with good blocking resistance may result in a window or door that sticks shut, even after the paint has dried. Ask your qualified paint professional to recommend a paint with good blocking resistance. Don't simply rely on a paint's price or brand name in making your selection. Expensive paint may not necessarily offer good blocking resistance. Also, ask your paint professional to recommend a wood primer and paint that are compatible and whether sanding is required between coats of paint.

      Explore the factory pre-finish options available for Pella's wood products.

  •   Where can I get paint or stain to match the interior and exterior of my Pella products?
    • Paints and stains for Pella products are available in quarts and gallons via special order through Lowe's stores or your local Pella Window and Door Showroom. You will need to provide the color of the paint or stain that you need to place an order.

      Or you may take the color or stain desired along with the substrate you are trying to match to your local Sherwin-Williams® or home improvement store and have them custom match the color.

      If you don't have a Pella paint chip or just need a small bottle of touch up paint or stain for dings and scratches, submit a request to Pella Corporation's customer support team or call (877) 473-5527 for further assistance.

      Be sure to consult with your local paint or finish store representative or professional to help address your specific finishing needs and review the Finishing section of your Pella Owner's Manual for details about how to properly finish your Pella products.

  •   How do I clean my Pella windows and patio doors? What can I use to clean them?
    • Clean the interior and exterior frame surfaces with warm, soapy water and rinse thoroughly. Stubborn stains and deposits may be removed with mineral spirits. Or Pine-Sol® can be applied with a clean, dry cloth or towel. Do not use abrasives. Do not scrape or use tools that might damage the surface. Should you need it, touch-up paint is available at the Pella Window and Door Showroom nearest you.

      Clean the window sill using the brush attachment on a vacuum and vacuum off any debris.

      It is normal for water to accumulate in the sill and track. On products with weep holes, the water is intended to drain to the outside via the drainage or "weep" holes.

      • To clean the weep (drainage) system, check to make sure that the weep holes are clear of obstruction (dirt, sand, or building materials).
      • To clean the weep holes, use a small, soft brush to clear the opening. Weep holes may be located both inside and outside the window in the bottom of the frame. If the window is "stacked," there may be weep holes between the units.

      WARNINGS:

      • Do not use abrasive or caustic solvents as they may damage your windows or patio doors.
      • Do not scrape or use tools that might damage the surface. 
      • Do not power-wash.

      Review the Cleaning section of the Pella Window and Patio Door Owner's Manual for additional details about how to properly clean your Pella windows and patio doors.
