Exceptional Quality Residential and Commercial Folding Glass Walls

Our Bifold Door System, also known as Folding Glass Walls or Accordion-Style Doors, features the narrowest stiles, largest panels, and is the most versatile folding wall system in the architectural glazing industry. Since 1998, we have been providing innovative solutions to home and business owners with superior-quality glazing products, that are designed and manufactured in the USA. Constructed of aluminum, wood or vinyl, our customizable, impact-rated bifold doors utilize patented technology and are continually tested to exceed industry performance standards. As a single-source provider, our door systems seamlessly match our other fenestration systems and through vertical integration, the majority of our hardware and accessories are precision crafted in our own facility to deliver the highest quality components.

MATERIALS

Aluminum Bifold Doors

ALUMINUM

Utilizing our most popular material, Aluminum Bifold Door Systems offer endless possibilities of sightlines, configurations, finishes, and operations. These durable operable walls are available in three standard frame widths: Standard, Narrow, and Extra Narrow — the narrowest stile width in the industry. Available in thermal and non-thermal varieties, the frame is also available in two thicknesses: our standard G2 (21/4”), which meets most needs or G3 (3”), which enables larger frames and higher design pressures. All of these systems feature an unmatched ease of operation and accommodate the largest openings.

Solid wood Bifold doors

SOLID WOOD

Wood Folding Glass Walls can be designed and configured like their aluminum counterparts. Through our patented framing process, utilizing a specialty glue-laminated (scantling) wood, these doors can be custom tailored to match the finish of the surrounding space. While wood products are often a slightly larger investment than aluminum or vinyl, these units carry excellent thermal performance. For applications where the Wood Bifold Doors are exposed to the elements, we recommend utilizing aluminum cladding on the exterior faces to ensure the longevity of the unit. Learn more about Wood Bifold Doors.

Cladding Bifold doors

METAL/WOOD-CLADDED ALUMINUM, WOOD-VENEER

Our Metal/Wood-Cladded Aluminum and Wood Veneer Bifold Doors showcase the beautiful qualities of specific types of metal or wood species while maintaining the superior performance and thermal properties of aluminum. With a wide variety of wood/metal cladding and veneer options, our Folding Walls can be cladded (or have wood veneer applied) on one or both sides. It is not recommended that wood be applied to exterior surfaces due to the damage severe weather can afflict on wood.

Vinyl Bifold doors

VINYL COMPOSITE

Vinyl Composite Accordion-Style Doors, are a versatile option for opening large spans for both residential and commercial applications. These low-maintenance folding walls, which require a smaller investment than their aluminum or wood counterparts, are the perfect solution to highlight a panoramic view or take advantage of the benefits of indoor-outdoor living. Vinyl Composite Folding Glass Walls provide excellent thermal and acoustical performance, reducing energy consumption while dampening the sounds of the outdoors. Learn more about Vinyl Bifold Doors.
