New Large Stile and Rail Pivot Doors and Sliding Doors
Stile and Rail Doors Using Sing Core Technology
Stile and rail doors are a foundational element in architectural door design. Sing Core’s patented and patent-pending technologies provide a structurally precise approach to building stile and rail doors that maintain long-term flatness and dimensional stability, even at large scales. Sing Core technologies allow stile and rail doors to be designed for projects where size, glass area, and precision exceed the limits of conventional wood construction.
Methods for Building Stile and Rail Doors with Sing Core
Sing Core technologies support multiple construction approaches depending on design intent, performance requirements, and budget.
Patent-Pending Large Stile and Rail Technology
Sing Core’s patent-pending stile and rail system enables oversized framed doors with high structural integrity. This approach is designed for projects requiring large dimensions, thin wood frames, or heavy glazing while maintaining straightness over time. This method provides a cost-effective alternative to fully paneled high-end door construction while retaining precision and durability.
Panel-Based Stile and Rail Appearance
Stile and rail doors can also be created using Sing Core panels with applied molding or trim overlays. This approach achieves the visual language of traditional stile and rail construction while benefiting from the rigidity and stability of a panel-based core. Sing Core panel construction allows manufacturers to produce doors of virtually any size with consistent tolerances and strong perimeter framing capable of supporting large light openings.
Sing Core technologies support large-format pivot and sliding doors using stile and rail construction. These systems were developed in response to projects requiring large glass cutouts, thin wood frames, and strict flatness requirements. The result is a wood-based stile and rail system with unusually high precision and structural performance.
Large Glass Cutouts in Wood Frames
Historically, large glazed stile and rail and French doors required aluminum or steel framing to maintain stability. Sing Core technologies allow wood frames to support large and heavy glass without joint failure or long-term warping. This enables architects to specify wood-framed doors for large openings without compromising performance.
Oversized Stile and Rail Doors
Sing Core can support interior and exterior stile and rail doors in sizes ranging from 10 ft. up to 40 ft. wide or tall. Large proportions, thin frame profiles, and demanding light openings are achievable using Sing Core technologies.
Stile and Rail Pivot Doors
Large pivot doors continue to be a defining architectural element in contemporary residential design. Traditional wood stile and rail construction is often limited by movement and distortion at scale. Stile and rail pivot doors built with Sing Core technologies reduce those limitations while maintaining the visual character of framed wood doors.
Challenges with Traditional Custom Stile and Rail Doors
Conventional stile and rail construction often presents constraints such as long lead times, size limitations, shipping challenges, and the risk of warping over time. Sing Core technologies address these constraints through engineered rigidity, scalable construction methods, and dimensional stability designed for long-term performance.
Large Wood Patio Doors
Large patio doors are frequently specified in aluminum or vinyl due to environmental exposure. Sing Core technologies enable wood-based patio door substrates and stile and rail frames to perform reliably in large exterior applications. These systems allow designers to retain the warmth and materiality of wood while meeting structural demands.
Rigidity and Dimensional Stability
Sing Core technologies are designed to deliver high rigidity and resistance to deformation. The result is a door core system that remains stable across large spans and varying conditions.
Frame Proportions: Wide or Slim
Sing Core allows flexibility in stile and rail proportions, from traditional wide frames to slim architectural profiles. Thin wood frames can be specified while maintaining the strength required to support large glass units. This capability enables greater freedom in façade and interior door design.
Design Flexibility
Stile and rail doors built with Sing Core technologies can be executed as hybrid panel and frame systems, panel-based constructions with applied molding, or standalone stile and rail frames. Each approach offers precision, strength, and dimensional reliability suited to high-performance architectural applications.

The picture above is a door that began as one of our famous true flat Sing Core door blank. They then overlaid trim, or molding, to create the appearance of a stile and rail door. As you can see, this door has been exposed to full weathering 100% of the time and shows no signs of warpage or failure. Our panel doors are used in the most high-end houses in the US.

WINDOW AND DOOR CUTOFFS
Sing Core provides Sing panels with window and door pre-cut and ready for installation. We will cut 1/8 larger in width and 3/16 inch wider in length to fit your window glass. We build a frame using 1.25 inch solid wood to your specifications.
MOLDING/TRIM
Sing Core windows and doors are profile ready for CNC routing. You may add molding or trim to create your own window or door design, otherwise we will provide you with thicker skin – such as 1/4 inch or thicker mdf, hardboard, etc. – for you to carve or profile by CNC machine. With Sing Core windows and doors you can create a true raised-panel door or any design you desire.
TRIMMED OR UNTRIMMED (RAW EDGES)
The standard ready-to-ship panel condition is, “untrimmed.” This leaves unfinished exterior edges that may have exposed adhesive and might require being built ½ inch over-sized for trimming at your location. An additional fee will be assessed for trimming and sizing in our factory.
All trimmed edges are 1/2 inch over width and 1/2 inch over length. After trimming, your Sing Panel will be 1/2 inch less (4 x 8 will be 47.5 inch x 95.5 inch). Standard solid wood edging with 1.5 inch will be reduced to 1.25 inch after trimming.
UNTRIMMED PANEL (RAW)
Many of our customers prefer their panels untrimmed because this allows them to trim their panels to exact size on site before installing them in their door openings. That way they can have the peace of mind that their door will fit the opening exactly as intended.

TRIMMED PANEL
Customers who want their panels cut to exact size before they receive them should choose the trimmed selection. This gives them the option of doing less work on site, but it also means they must be much more precise with their measurements before ordering their panels. Trimmed also costs slightly more because it is more labor intensive to trim the panels in house.

What Is A Pivot Door?
A pivot door rotates on a pivot box in the floor and the top jamb rather than traditional door side hinges, which is common in most homes. Pivot Doors have become a popular choice for entrances, creating a bold statement at your first point of contact.
What makes pivot doors so unique? The pivot door or pivot window is an opening system with a central or lateral rotating axis that allows for very large door panels. The craftsmanship and technology of a pivot hinge allows for a larger opening than most other types of doors since traditional hinges cannot carry the same kind of weight. Pivot doors are fantastic options for where there is a large amount of space and enough floor room for the door to be able to swing all around.
Grounded in the principles of modern architecture, a pivot door emphasizes clean lines and simple shapes. Pivot doors are well suited for pivoting walls and can also be used as room dividers. Until now, affordable pivot doors are thicker than average doors and heavy in weight. The large size and heavy weight causes extra costs associated with shipping and handling. Shipping is more expensive because shipping costs are calculated on weight. Handling is more expensive because heavy equipment is necessary for transporting and manipulating the pivot door into place for installation. Pivot door hardware is also based on the affordable pivot door’s weight, so a heavier pivot door will require more expensive and heavy duty hardware. Here at Sing Core we manufacture custom premium wood pivot-hung entry doors for exterior and interior use. Our pivot doors feature our patented lightweight insulated torsion box pivot door core inside. Which imbues each door with the unique characteristics of a solid core pivot door featuring the exact size, material and appearance of any style of pivot door, while remaining extremely lightweight and incredibly strong. Independently University tested at 660 PSI, makes Sing Core’s pivot door core stronger than steel pound for pound. The pre-insulated core also means greater climate control and noise cancellation between spaces. Also, the lightweight of Sing Core’s pivot doors, means less shipping, handling, transportation and installation costs, requiring less expensive hardware.
A pivot, not a hinge rather than hanging from hinges in the frame, a pivot-hung door swings on a set of pins mounted in the top and bottom of the door. Transform the look of your home or office by opting for Sing Core’s affordable pivot doors. Pivoting front entry doors provide an elegant look and appear to float inside the door frame. We are offering premium wood pivot-hung entry doors for exterior and interior use that cannot be found anywhere else. Let Sing Core build your custom pivot doors, custom modern entry doors, exterior mahogany wood doors, or any other custom door you can imagine! If you can create the idea, we can create the door. Every Sing Core door comes with a 50 year structural guarantee, something that no other door company has been able to offer.
Swing-out Carriage Doors
Are you in need of replacing those old carriage doors? Maybe you just want to spice up your home a little bit? Carriage doors are a great way to do this. They are very large, and yet so elegant. Carriage doors can replace your roll-up garage door. It will save you an immense amount of space! Carriage doors use a series of hinges instead of a track as the roll-up garage doors use. Using Sing Core makes your installation simpler, doors last much longer, and are significantly easier to handle. Easier handling means that your shipping cost will be even more favorable!
Hinged, swinging, swing-out, swingout, swing-in, swing, slide, or fold carriage doors for your carriage house garage can be found at Sing Core. The old-fashioned design, side-hinged garage doors swing open and closed from a hinged frame on either side of the opening. We create the most lightweight, strongest, and economically friendly doors. Traditional carriage doors are very heavy due to their size and structure, which causes them to need very heavy duty hardware to hang the door. The idea that carriage doors open on heavy duty hinges my not seem like a hindrance, but it raises the cost of hardware and make the door increasingly more difficult to install. So make it easier for yourself or your contractor to install your carriage doors by using Sing Core doors. Sing Core proudly makes any size (no matter how large) door tailored to your needs. Our doors weigh a third of a standard carriage door. Don’t think for a second that this weight difference alters the quality. Sing Core doors are the strongest doors on the market today. We believe so strongly in this that all of our doors are backed with a 50 year structural guarantee. No other door company can come even close to that!
Carriage style garage doors swing open elegantly and add a classy look to homes. Custom swing out garage doors are becoming more popular each year. Out swing carriage doors allow garages to be turned into living spaces, and they’re great for garages that have limited head room or living areas where you do not want to have all the overhead track. Swing-out, side-hinged heavy double doors can be served as the entryway to your home even! With a classic, yet highly unique, twist on modern garage door functionality, the side hinged garage doors are perfect for anybody who is looking to spruce up their home. Sing Core happens to be the #1 custom carriage house wood garage door manufacturer. We create custom swing out garage doors that are made to order and can be shipped throughout the USA and even abroad.

Large Barn Door Problems
If you were going to make a high-end large barn door for a demanding client or visionary contemporary architect, you would have to hire a door engineer with the ability to design sliding barn doors which could be built to architectural specifications. The goal is to have an end product, a large barn door, which will not warp, fail, or require regular ongoing maintenance to keep it operational over time.
If the large barn door was quite oversized, say anything over three-and-a-half ft. wide and 7 ft. tall, you would find some extreme goings on inside such a door. There would likely be some type of welded steel interior framing and other heavy inserted in an effort to keep such a big barn door from warping, a pretty toxic approach to trying to solve the problems associated with large barn doors.
This is the biggest complaint with failing large barn doors: They warp. And warping barn door, if they are warped enough, will cease to operate, and if they are very heavy, this causes extra stress and strain on both hardware and the structure itself.
