Folding Glass Walls

Folding Glass Walls

Folding glass walls are a signature product of Solar Innovations®. The industry also calls them bi-fold doors or accordion style doors. These doors accommodate any number of panels in addition to configurations. Solar Innovations® provides in-folding and out-folding glass walls thus accommodating the needs of many applications. Swing doors (also known as man doors) can be integrated into the folding glass walls. This allows the user to quickly enter and exit a room without operating all the panels. Folding glass walls are engineered by Solar’s in-house engineers to allow high DP ratings and ensure they withstand extreme circumstances.

These walls provide flexibility and span larger openings than traditional doors, providing seamless transitions between structures and the outdoors. Folding glass wall systems can, in addition, be used for any number of applications. Some of these applications include stadiums, hospitals, hotels, and other applications.

Residential Folding Glass Door

Commercial Aluminum Folding Glass Walls or bi-fold doors


As an American manufacturer that specializes in custom folding glass wall systems, Solar Innovations® is ideal for commercial glazing solutions. In addition, Solar creates folding glass walls that are completely customizable.  Solar’s specifications simplify the process of incorporating Solar’s products. It is impossible to mention every product application or configuration because there are simply so many.

Commercial hardware options include single and double door panic hardware, corrosion-proof two-point locks, ADA compliant sills, high-performance sills for high wind and water applications, as well as door catches and closers. Solar also has a ten-inch bottom rail available for ADA compliancy if needed.

Residential folding glass walls can virtually be anywhere in a home. These glass partitions can be used for exterior applications, where there will be contact with wind and water. We also use them as interior operable partition applications where there is no contact with the elements. This system can be fitted into pool enclosures, garages, and sheds. When the glass partition is open, you are presented with ample space for a lawn mower or car to pass. You can add an operable panel into the unit, depending on the configuration of the doors. This door allows you to pass through one panel, like a terrace door, instead of opening the entire unit.

If you desire the functionality of the folding glass wall system, but have concerns about insects, add a Screen System.

Thermally Enhanced

The thermal break separates the aluminum and minimizes conductivity of heat and cold from the inside to the outside while ensuring the structure’s interior remains comfortable at any time of year.

Hurricane Impact Rated

Our company currently offers the largest selection of products tested for Florida ratings, as a result, they withstand even the most extreme weather conditions.

Ease of Operation

Solar Innovations’ systems offer single-handed operation resulting in smooth movement with little effort. Because much of our hardware is manufactured in-house it allows us to control lead times.

Monstrous Sizes

Solar Innovations® also has the ability to manufacture even larger panels that operate with greater ease for several functions: folding, sliding, swinging, and stacking.


In our contemporary world, architects, homeowners, and business owners desire expansive windows and doors with minimal framing obstructing the view. Our marine glazed folding glass wall systems span large openings and provide seamless transitions. Even while closed, its narrow vertical frame maximizes views, reducing framing members and creating a clearer view.

Our patent design for the marine and stop glazing system combines vertical marine glazing with horizontal stop glazing. As a result, creating a narrower vertical frame than conventional stop glazed doors. The high-performance marine and stop glazing system by Solar Innovations® has the narrowest four-sided glazed door. Now available for pivoting, stacking, swinging, and folding door units.

In a marine glazed system, the glass extends into the left and right framing members, eliminating the need for glass stops at the vertical frames. The hybrid marine and stop unit is structurally glazed within the glazing pocket.

Glazing Options

Creating the perfect environment for your home can be a complicated task. Ensure your project looks and feels like the unique design parameters of your home, Solar Innovations® offers many glazing options. Your glass can be acid etched, frosted, art glass, or contain applied grids with multiple pattern options.

LowE Glazing helps maintain temperature, energy consumption, and reduce the natural fading process the sun has on furniture and windows.

Testing Information

Solar Innovations, Inc.’s folding glass walls offer superior testing results, including Florida (including Miami DADE/HVHZ) and Texas (TDI) approvals, NFRC certification, high DP ratings, ADA compliant options, and offer low maintenance solutions for most applications.  Solar Innovations®‘s in-house engineering team comprised of architects, engineers, and drafters, modify each project to match the exact parameters required by the specification. This allows Solar Innovations® to provide an industry leading customizable product for any application.

Solar Innovations® specializes in aluminum framed folding glass walls and offers the largest tested panel (3′ ½” x 9′ ½”) currently on the market for Florida impact ratings.  A single non-impact rated panel can reach up to five feet wide by fifteen feet tall (5′ x 15′) and is ideal for multiple story buildings or large spans.  The majority of Solar’s products, including the Series SI3000 thermally enhanced system, have been impact, water, and structurally tested for superior performance in any climate.  Any specific size and combination of customizable options that are not currently tested can be mocked up, tested at Solar’s in-house testing facility, and certified by a third party.  This state of the art facility with third party certification allows Solar to reduce lead times for commercial and residential projects requiring testing approval with custom configurations.  Any application can be completely customized to provide limitless design flexibility in hardware and stile widths.
