Sing Stile and Rail Doors

The Sing-style approach to stile and rail doors is a horse of a different color amidst the age-old door industry. Sing stile and rail doors are lighter in weight and stronger than steel yet made of nearly any flat building material available, not matter how they’re built.

Sing Stile and Rail Look

Our most sought-after stile and rail manufacturing method produces a stile-and-rail-looking door from a solid composite Sing door slab which feature alternating wood grain orientations on the door surface to emulate the look and feel of a stile and rail door without any weak spots.

The resulting Sing Stile and rail door made of a solid door panel is the strongest, lightweight, most insulated, Eco-friendly door proudly made in the USA.

Sing Stile and Rail Construction

Even among the most tried and true stile and rail door manufacturers, they know that the only way to build a large stile and rail door which can be guaranteed not to warp for 50 years, is with Sing Core inside.

Rather than build a stile and rail looking surface and applying it to a solid slab of Sing Core, traditional stile and rail manufacturers prefer to use stile and rail components with Sing Core inside.

Basically, this means that all the stile and rail components are manufactured by Sing Core in building material formats which are very similar to our post and beam configurations, and/or furniture panels. These are assembled by your favorite stile and rail door builder just as they would any traditional wood stile and rail door components.

Sing Stile and Rail Advancements

You might be surprised what benefits can be enjoyed by custom door makers who construct their doors using patented Sing products. This new, revolutionary door building material is

Lightweight Stile and Rail Doors

Weighing in at a fraction of other solid core doors, Sing stile and rail doors can be very lightweight, even if they are very big doors, without threatening the longevity of the door’s performance over time.

High Strength Stile and Rail Doors

Stile and rail doors made of Sing Core are incredibly strong. Rated at 660 PSI, Sing Core is stronger than steel pound for pound, thanks to Peter Sing’s patented solid composite torsion box core substrate, incredible unsupported spans are possible, enabling doors with Sing Core inside to outperform any other lightweight door.

50 Year Stile and Rail Guarantee

Professional grade Sing Core has such a high precision tolerance (+/- .006 in.) and withstands just about any variance in conditions across the board, that these are the only door which can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years, including full structure warranty.

Eco-friendly Sing Core

Using Sing Core is the Eco-friendliest way to build a sustainable door, which is made with a smart combination of minimal natural and recycled material combined to create this revolutionary door core material which is the lightest weight and highest strength way to build doors of any kind.

New Revolutionary Door Technology by Sing Core

We offer our services to support door manufacturers in building stronger, lightweight, high precision and warp-free (AWI warp standard) insulated doors using our patented and patent pending Sing Door Blanks and Sing Stile and Rail frames.

Sing Core’s specialty is assisting to create incredibly large and extremely wide door panels which door manufacturers can utilize to build the most challenging high-end doors.

Large Quantity Production Runs

We can also assist in the high-quantity production runs for doors using our facility to pre-build base doors which might otherwise create a bottleneck for common door manufacturers. We love taking over the assembly line bulk of your large door orders with rapid turnaround times.

You choose your method of building your Sing Core door blanks:

1. Sing Door Core Panel

You specify the length, the width, and thickness of your Sing door blank, built to your specifications. You determine the insulation value and skin material, and we do the rest. The Sing door core panel method is the strongest and best Eco-friendly insulated door solution for any sized door, even large oversized wooden doors, available in almost any style.

2. Stile and Rail Door Frame

For our customers and their clients who prefer the standard design of stile and rail doors, we provide the manufacture of a stile and rail formatted frame made of any combination of Sing panel, post and beam configurations to create the most sustainable stile and rail doors, which are finished by only the best millworks and custom door manufacturers. Sing Core provides the most significant improvement to stile and rail technology (besides automation) in the last 100 years to create the strongest, lightweight, most high-precision, and warp-free performance in the history of the door industry.

Doors of Almost Any Style Could be Made with Sing Core Inside

1. Pivot Doors

Pivot doors are the highest and best use of Sing Core because for the most part, pivot doors are quite large in size and are often much thicker than a standard door. If your intention is to feature a real wood finish, you know you’re going to be in trouble, that’s when the warp-free attributes of patented Sing Core shines through as the only way to build a large wood door which can be guaranteed to offer warp-free performance over time: 50 years, guaranteed, on professional grade doors.

2. Sliding Doors / Pocket Doors

Sliding Doors often present problems when they are very large due to their sensitivity and tendency to move, bend, or cup in response to changes in the environment, for which Sing Core is the perfect solution.

Large bypass sliding doors are likely to deface, scar, or otherwise damage themselves if they are not kept straight and true by being built with Sing Core inside in advance of bypass door failure.

Pocket doors, which are the most problematic of all sliding doors, because they hide within a cavity are highly benefited from being built with Sing Core inside. If warped, the finish of the door may be compromised as it brushes against the frame or cavity’s interior, and if it cups or bends too far, may become lodged either inside or outside of the pocket unable to open and close as a door. Sing Core keeps them straight and true.

3. Hinged Doors

Hinged doors are for the most part manageable even when facing a certain degree of warp, which is normal in normal sized doors. Problems arise when doors are very large, especially if over 7 ft. tall or 3.5 ft. wide. Any movement or change in the door’s being compromised is increased exponentially in relation to the dimensions of the door. Not a problem with Sing Core’s professional door blanks.

Diverse types of hinged doors, such as French doors, sliding folding doors, front entry doors, and carriage doors (among other types of hinged doors), all present varying challenges when migrating from the drawing board to the real world, and Sing Core makes the difference.

Door Sizes

While Eco-friendly insulated Sing door blanks could be used in doors of any size, the efficacy is maximized in door performance in any door over 7 ft. tall and 3.5 ft. wide. This is why you find Sing Core inside the largest doors in high-end homes, businesses, and industrial sites, because it’s the only way to build a large door which can remain straight and true, regardless of the size of the door, while still remaining lightweight.

Door Shapes

Since every door slab manufactured by Sing Core is likened unto a one-of-a-kind piece of art, architects and designers are free to create a door of any size and shape using any available flat building material.

Sing door slabs can be created to accommodate any shaped design in any thickness, and so it goes for any shaped light cutout for glass openings.

Skin Options

Sing door slabs are available in almost any skin you want, limited only by flatness (surface material must be flat), ability to be laminated, and availability.

Some examples include, paint grade plywood, aluminum, brass, cement board, cold rolled steel, concrete, diamond plate steel, fiberglass, FRP, galvanized steel, glass, hot rolled steel, LVL, Masonite, stainless steel, any wood species including exotic species, and many more.

Our most common specialty includes the cold pressing of solid wood stave to our patented and patent pending core material, resulting in natural wood doors that can be guaranteed to remain warp-free for 50 years. Unheard of in the wood working industries. We also supply high end millworks with hot-press-ready warp-free substrates to apply their skins to.

Light Openings

Available in any size and any shape, based on your drawing(s).

STC-rated Sound Doors

We assist in the creation of sound reducing or sound proof doors which can be STC-rated at our local world-renowned pro sound testing lab. Some typical composite configurations include combinations of steel, sheetrock, MDF, and other materials to achieve the sound proof results to meet your specifications.

Fire Proof Doors

We build fire proof doors to your specs and can have them rated at the fire-rating facilities selected by our fire proof door clients.

And that’s just scratching the surface…

Cracks in Wood Stave Doors

Here, at Sing Core, we get calls all the time about problems associated with wood stave doors, especially if they are large, oversized wood stave doors. These problems, such as bending, twisting, cupping, and warping should be celebrated as wood’s natural tendency to adapt to it’s environment. Unlike other synthetic materials, wood stave is sourced from a previously live authentic tree unique unto itself, a valuable resource in the eco structure of our planet.

A tree is a living, breathing part of our environment, made of the same atomic stuff we are, a sort of shirt-tailed cousin, which survives consciously for years by continuously adapting to its environment.

Even following the harvesting of a tree’s wood, the wood’s independent slices fight for their right to continue to acclimate and survive, expressing their individuality and uniqueness.

That’s why designers, architects, and pretty much the rest of us love the look and feel of real wood. We appreciate the look of it, the design of the individual expression of the tree’s growth rings, and it makes you have a comfortable sense of being home in a virtual hug from Mother Nature.

When wood stave (natural slices of wood) is applied to a door core material, the wood will move to accommodate the environmental challenges and circumstances which it is presented with.
In the case of cracking wood stave doors, the surface crack is the nature of the wood to adjust to the tension of the door’s core. The wood is still trying to provide you with the best door ever, so it sacrifices the surface finish and moves to accommodate the needs of interior core of the door. A crack-resistant finish will result in the tension being spread over a larger surface area, developing a warped or cupped door which can be more problematic to deal with than a surface crack.

Natural wood stave doors will move, warp, bend, twist, and crack, unless they are uniquely engineered with the proper composite materials to result in a wood door that does not move.

Sing Core provides architects, custom door manufacturers, and millworks with the best structurally sound composite door core which is lightweight, insulated, dimensionally stable, and stronger than steel pound-for-pound. Properly laminated materials, including the application of the natural wood stave to the patented torsion box composite core in concert with patent pending straighteners, delivers to clients a natural wood stave door which can be guaranteed to remain warp-free, including a full structure warranty, for an unprecedented 50 years.

A cracked natural wood surface door is likely due to a moisture problem, which varies in intensity between interior wooden doors and exterior wooden doors. Any wood door needs to be properly acclimatized to avoid cracking and excessive movement, also contributing to a wood’s tendency to move would be considering the way in which the wood was sliced, cut, or sawn.

Wood stave is a much higher concept in wood-faced doors than wood veneer as wood veneer which is not susceptible to cracking or warping, it is very thin and cannot easily be repaired when slightly damaged. Wood stave is a thicker natural wood product which can easily be maintained using basic woodworking skills.

How to Measure a Warped Door

How can you tell if you have a warped door or not?

There is an industry standard method of determining whether your door is warped or not.

To determine whether you have a warped door or not you will need a length of string (longer than the length or height of your door) and a measuring stick or tape measure.

a) Tape one end of the string to the edge of the door and the other end to the opposite edge of the door.

The string should be straight. If there is a gap between the string and the door’s surface, you may have a warped door.

b) Measure the gap between the string and the door’s surface area.

If the gap is greater than ¼” your door is warped (according to AWI standards for 1-3/8 to 1-3/4 inch doors 3’-0” to 3′-6″ x 7’-0”).

c) If the length exceeds 7 ft. AWI standard applies to any 7 ft. section. Apply string to any 7 ft. span.

Contact your door maintenance company and send them two photos.

d) [1] Photo of the length of the string which shows as much of the door in its entirety, or at least from one end of the string to the other. Then [2] a closeup photo of your measurement of the gap.

Armed with these two photographs, which can easily be emailed to the millwork or door maintenance company of your choice, the recipients will be able to determine how best to approach the repair or replacement of your warped door.

You might consider replacing your warped door with a professional door which has Sing Core inside which can be guaranteed not to warp, bend twist or otherwise fail so as to avoid this pitfall in the future.

For more information, see: Door Warping vs. True Flat

What if my door with Sing Core inside is warped?

The same standard method of determining and measuring any door with Sing Core inside is used just like any other door (as noted above).

Contact Sing Core about your concerns about your door being certain to include the two photos as noted above.

If you have purchased a professional door with Sing Core inside, you may be the recipient of a replacement Sing door.

Note that upon arrival and un-crating of a door with Sing Core inside, a door may appear warped (and indeed it will be measurable). This is normal for a door which has been packed and in transit. Stand your door on its edge at least twelve inches away from any adjoining surface area, allowing it to acclimatize for up to 72 hours. Measure your door again and you will find it to be straight and true. If not, document for warp (as above) and contact Sing Core.

In the event that a professional door with Sing Core inside is warped (which is highly unlikely) your help in determining the cause of the door’s warping is appreciated. Please assist documenting the chain of custody of your professional door with Sing Core inside, including the millwork or door company which finished the door, and the installers who installed the door, to help us insure your replacement door remains warp-free.

Standard-sized Doors for Retail

You asked for it, and Sing Core delivers, and as always, goes the extra mile.

For years, Sing Core has been providing the most exclusive solutions for large high-end door manufacturing, made available to only the best custom door manufacturers and millworks. Since we started supporting the door industry rarely does a day go by when we aren’t dealing with many requests for standard-sized doors for retail installations.

Unfortunately, since our factory is only set up for one-off custom large doors, the cost of making a standard-sized door with Sing Core inside is just too cost prohibitive, except in the most high-end jobs with a large budget for architectural doors. That is, until now.

Introducing Retail-ready 3-0 x 7-0 Sing Doors

Financed by our success of building high precision Eco-friendly one-of-a-kind warp-free doors that can be guaranteed not to warp, bend, twist or otherwise fail for 50 years (no other door company in the world can do that without having Sing Core inside), we have created a new division at our factory to build standard-sized 3-0 x 7-0 doors with Sing Core inside.

These warp-free flush doors are priced to sell, so that you can now provide the best doors to your retail clientele featuring Sing Core inside at a price point that is attractive and affordable.

Priced for Retail Kick-off Event

We are kicking off this new line of retail-ready doors in the most requested size: 3-0 x 7-0 doors, available for either interior or exterior applications. You also get to choose from paint grade, veneer, or natural wood stave Sing flush doors starting at $xx.xx each, with no minimum order.

Standard lite cut outs are available (8 styles to choose from). Doors with window openings cut require a 10 piece per cut out design minimum order.

Strongest Lightest Weight Doors in the World

Kick My Door

As we kick off this event, inventor Peter Sing invites you to kick his door, which is so strong, “You will break your leg before you crash my core.”

Sing Core is renowned world-wide as the only way to build a lightweight door using high precision (+/- .006 in. tolerance) core material which is stronger than steel pound for pound (660 PSI) for building doors that can be guaranteed not to warp or fail.

Note: Kick doors with Sing Core inside at your own risk.

Ready to Ship Unfinished Doors to You

As always, Sing Core does not finish, provide hardware, or pre-hang doors. Prices are for unfinished door slabs only.

To sweeten the deal even more, we will ship to your company direct. Sing custom doors are only shipped to millworks and custom door manufacturers only, because finishing and creating the ultimate warp-free door depends highly on the craftsmen who create the finished product.

Since these are standard 3-0 x 7-0 sized doors, there is plenty of hardware and retail-ready framing material available over-the-counter, so these doors do not require the same attention to details as our custom-sized doors. The only thing is, we need to trust your skills in finishing the door.

5-year Warp-free Guarantee

Assuming the door is adequately sealed and finished, Sing Core guarantees every one of these doors, both interior and exterior doors, to remain warp-free for 5 years, including full structure warranty.

Now you can order with confidence and at special retail-ready pricing your choice of 3-0 x 7-0 doors with Sing Core inside.

1. Paint Grade Door

2. Wood Grain and Wood Stave Door

3. Hardwood Plywood Door

1 Paint Grade Door

Our most popular door blanks are paint grade, and can be made to your specs including surface materials of,

  • Birch ply (most common)
  • Wood plywood
  • MDO
  • HPL
  • Other material, as specified

 

2 Wood Grain and Wood Stave Door

Besides paint grade for the surface, we also provide solid wood stave laminate on both sides of the sliding door. Wood stave is easy to work with and will last. Your Sing wood stave door will be more high precision than solid wood door (less warping, and twist and crack) due to Sing Core’s extremely high tolerance (+/- .006 inch) and, rigidity and high strength (660+ PSI) and professional grade wood grain and wood stave doors are certified and guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

Sing Core provides hot-press ready door blanks to door manufacturers who add wood veneer on both sides of Sing door blanks which are made of Luan skin or marine grade plywood sandwich with patented Sing Core in the middle, solid wood around 4 edges and wood block implants where needed for hardware.

oversize-panel-edge-glued-together-planks-5ftx10ft Sing-Hardwood-Panels-Variety

Note: Veneer has to be handled very carefully every step of the way during production (we prefer to let the millworks handle this delicate procedure) and it is easy to damage by users over the years (but wood stave can be easily sanded and repaired).

We offer a very good price for wood stave doors, the cost is not much more than wood veneer doors.

3 Hardwood Plywood Door

We could make door with hardwood plywood as an effective way to make super large doors that you can stain any color. Up to 4×8 doors have no seam, but by orienting the grain horizontally, you can achieve a nearly seamless presentation on really big doors or extraordinary size.

Available in any available wood species, most common are Sapele, Oak, and Maple ply.

Sing Hardwood ply door has excellent strength, yet is lightweight, features good insulation and better sound deadening qualities than solid wood plank doors.

Wooden Door

Sing wooden doors make the best wooden doors in the United States and around the world. No other Eco-friendly lightweight wooden door core is stronger. Weighing in at a fraction of the weight of solid wood door core, patented Sing Core is stronger than steel pound for pound (660 PSI). This is the only way to make a large oversized wooden door that can be guaranteed not to warp, bend twist or otherwise fail for 50 years.

The Only 50 Year Warp-free Guarantee and full structure warranty

Each professional Sing wooden door can be guaranteed to remain warp-free for 50 years, including a full structure warranty. This is why Sing Core wood doors are making such a huge impact on the door industry across the USA and abroad.

 

Any type or style of wood door can be made with Sing Core inside, such as exterior wooden doors, wooden barn doors, interior wood doors, wooden sliding patio doors, wood sliding room dividers, wooden French doors, wood stile and rail doors, just to name a few.

Patented Eco-friendly wooden doors with Sing Core inside are proudly made in the USA, using sustainable manufacturing methods using less energy, with responsible use of recycled and renewable resources, including natural wood fiber, producing little or no waste or loss of energy, leaving a negligible carbon footprint.

There is just no other way to make 20 ft. tall wooden doors that will not warp. Wood is a very difficult resource to use for anything over 7 ft. tall because of its tendency to move, especially in exterior wood doors. For instance a wood door that faces the elements on one side and the structure’s interior on the other is going to warp. That’s why no door company guarantees warp resistance of a wooden door for more than one year, that is, unless it has patented Sing Core inside.

So, how can you get wood doors with Sing Core inside? It’s easy, just go to your favorite architect, door manufacturer, mill work, or custom door company, and tell them what size door you want and be sure to ask for, “Sing Core inside.” We cannot sell or ship Sing Core doors directly to consumers or do it yourselfers, as we are the manufacturer supplying Sing Core door core only to door manufacturers and builders of custom doors.

 

Choose any available type of wood for your wooden doors with Sing Core inside, such as,

Black Oak Doors

Cedar Doors

Large oversized wooden doors are the greatest hurdle facing architects and designers, because though there is little more impressive than a huge wooden door to catch your attention, so the bigger the better, but then there’s the issue with warping, which is a constant struggle for the owner to secure regular maintenance of such a beautiful wood door, likely at least seasonally.

Thanks to having Sing Core inside, you will never have to worry about warping wood doors again. While they are built to last for centuries, each professionally guaranteed Sing wooden door can be non-warping and include a full structure warranty for 50 years. No other Eco-friendly, lightweight, high strength wood door can have such a guarantee in the world.

And what if you’re looking to build a large door out of a material other than a natural wood grain? No problem, your doors could be made out of any available flat building material, such as aluminum doors, cement, concrete, fiberglass (FRP), glass, HPL, Kevlar, LVL, MDF, steel (cold rolled steel, steel diamond plate, galvanized steel, hot rolled steel, etc.) as well as the only unbreakable mirror doors, just to name a few.
