Vinyl Folding Glass Walls

Open the widest spans with the most versatile doors in the industry.


Vinyl Bi-fold Doors, or Folding Glass Walls, 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. Solar Innovations® also offers a variety of screen options with matching frames, to keep those pesky insects outside. Vinyl Folding Glass Walls provide excellent thermal and acoustical performance, reducing energy consumption while dampening the sounds of the outdoors.

We just finished installing the 2nd order of folding glass wall systems into our client, Red Dot restaurant’s building. I decided to write this letter because I’m so impressed with your product. Both systems were well documented, packaged, and built. We have no detectable air infiltration in 15kt wind and it was 10 degrees out! You make a great product. Thank you and Happy Holidays!

Just writing a quick note to say the greenhouse you fabricated and installed on the Concord, MA house we designed looks great, and has been a big hit with the clients. The GC told me the install crew did a good job. On the recent cold days we have had (before the heating system is up and running) it has been the favored place to hang out.

Our builder here in Morganton, NC – Cottonwood – is so impressed with your products in our home that they would like to incorporate big windows and doors into new homes they are designing and constructing.

Tracy and Rich Krause | Morganton, North Carolina 

The skylights are in, the sun is shining through them and they look great. Your installers were very professional and pleasant and left the job site in an immaculate condition. Thank you for all your assistance throughout this project. I am delighted to have my sunroom back!

Glazing choice plays a critical role in the performance of your folding glass wall. Most units exposed to the outdoors use insulated glass, which is constructed of two or more panes of glass separated by a stainless steel spacer and infilled with Argon gas. Performance is further enhanced with Low-E* coatings that allow the sun’s rays to pass through the glass while reducing the amount of heat transfer. U-values measure the amount of heat transferred through glass. The lower the value, the better it insulates. Monolithic, or single pane glass, is suitable for indoor applications, except where acoustic performance is desired. If you are looking for a particular glazing type, we can customize your doors to your specifications.



LoE 272 Cardinal Glass


LoĒ²-272 is the most common and has a very slight green tint and assists in regulating temperatures, keeping it cooler in the summer and warmer in the winter.

LoE 340 Cardinal Glass


LoĒ³-340 is used when the space needs to be shaded from intense direct sunlight. A coating is applied to clear glass, which blocks the sun and causes a soft blue tint.

LoE 366 Cardinal Glass


LoĒ³-366 is the best insulation choice. It blocks 95% of the sun’s harmful UV rays, which helps preserve the color and composition of furnishings, draperies, and wall treatments.

LoE 180 Cardinal Glass


LoĒ-180 is an ideal choice for buildings attempting to generate solar heat gain, particularly with cooling accessories. This glazing is popular for colder climates.

LoE i89 Cardinal Glass


This energy-saving fourth-surface, coated glass can allow for double-pane windows to meet ENERGY STAR® guidelines. LoĒ-i89 is applied to the indoor surface, preventing heat from escaping the room and lowering U-factors.

*Low-E = low emission; LoĒ = product name of Cardinal Glass Industries


Solarban 60 Vitro Architectural Glass


Solarban 60 allows 70% of visible light to pass through while blocking 62% of solar energy providing year-round comfort and energy savings.

Solarban 70 Vitro Architectural Glass


Solarban 70’s triple silver Low-E coating allows 64% of visible light to pass through while blocking 94% of UV energy, protecting indoor fabrics.

Solarban 90 Vitro Architectural Glass


Solarban 90 allows 51% of visible light to pass through while blocking 80% of solar energy providing year-round comfort and energy savings.

Folding Glass Walls, or Bi-Fold Doors, are a great way to bring the outside in, but opening a wide span also allows entry for pesky insects. Solar Innovations offers a wide variety of screen types that perfectly integrate with your Bi-Fold Doors.

Folding Screens

Folding screens mimic the flow of their glass door counterpart and are constructed of the same material. Folding screens are hinged and fold left or right to be flush against a wall. Just as with glazed folding doors, operable swing door panels can be integrated into the door units to provide an entrance. Folding screens can also be used to create an outdoor living space, allowing you to enjoy nature without bothersome insects.

Stacking Screens

Screen systems do not need to mimic the operation of their glass counterpart. Stacking screens are individually operated, top hung panels that slide and stack in a designated location. They are constructed of the same material as the Bi-Fold Door and can include an integrated door for easy egress and entrance.

Sliding Screens

Sliding screens do not have to be used with sliding door systems. They can also work in tandem with Bi-Fold Doors. The panels can be operated from the center or stack from either side of the doorway and can be pocketed into a wall cavity. For perfect cohesion, they are constructed from the same material as the Bi-Fold Doors.

Finish and Screen Options

Folding, stacking and sliding screens are available in all of our standard finishes and screen options. These are smooth, non-pleated screens that can be used in most project applications.

C Series Ecoscreens

C Series EcoScreens combine the functionality of both an insect screen and privacy shade. The unit is available in an all-screen configuration, an all-blind configuration, or a combination blind and screen unit. The blinds and screens are retracted from vertical cassettes on both sides of the opening and feature an anti-slam mechanism. The blind portion of the unit can also function as a projector screen for your home theater system.


C Series Sample Configurations

G Series Retractable Screens


Solar Innovations® offers a retractable screen with a stylish, pleated material that can be operated with one hand. Units may include one to six panels and can be parted at any vertical rail. G Series Screens have an ADA compliant sill track and are available in several frame finish options. These screens can typically be designed to match the vertical rail alignment of the door system they are complementing, minimizing siteline interruptions.



Milano screens can be either a single unit that pulls left to right or a double panel which joins in the middle and then retracts back to the framing. They are held together in the center with industrial strength magnets. Screens allow users to easily pass from inside to outside and can be stopped at any point on the track with the anti-slam feature. Several frame finishes and sizes are available that will suit most openings.

S Series Retractable Screens

S Series Screens are vertically retractable screens that provide the ability to enjoy the outdoors while being protected from pests. S Series Screens feature a specialty zipper system which guides the fabric within the track and prevents insects from entering. The zipper system can also prevent sunlight from entering the room if black out fabric is selected.

VistaView screens are a horizontally retractable system that allow unobstructed views without any visible frames, pull bars or seams. They are capable of screening openings up to 11 feet tall and 28 feet wide. Operable with just a single hand, these durable screens are made with a wind and pet resistant mesh.


Horizon screens are a horizontally retractable system and can be paired with a wide array of door types. A single screen can open up to 21 feet, or paired with an opposing screen to double the protection to 42 feet. This system features an auto-stop function that can stop anywhere along its track, allowing for easy access.

When designing a three-story restaurant overlooking the Chicago River, a client approached Solar Innovations® for a custom Folding Glass Wall. The bi-fold wall would be located on the third story, which is designed as a high-class bar and lounge area with grand views of the city.
