A Low Cost Alternative Way to Build Very Large Sliding Doors

Although not as tough as our original one piece door designs with a 50 year guarantee, our segmented doors still come with our patented Sing Core structure inside and carry a 5 year warp-free guarantee. And, they can be sold at a much reduced price.

In the past, very large and oversize specified doors were often made as a single piece and shipped whole to the contractor for installation. This is particularly true of very large pivot doors and sliding doors. With modern door construction techniques pioneered by Sing Core large doors can be produced and shipped to the customer in several pieces. These segmented doors pass on savings to the customer while maintaining the highest quality standards for warp free door construction.

Benefits of Modern Segmented Door Construction

Building a door in sections provides numerous benefits without compromise in strength, lightness, and flatness:

See Them Come Together

More Efficient to Build

Constructing a door in smaller sections makes the door easier to handle in the factory and easier to produce in general. Having more manageable sections leads to quick and efficient construction, at a cheaper cost. Doors constructed with our modern sectional approach pass on savings to the customer.

Cheaper to Ship

Doors cores produced in sections are built to be convenient and cheap to ship compared to a door built in one piece. This may reduce shipping costs payed by the customer to receive their door purchase.

Easier to Handle

Very large doors constructed in segments conform to common sizes. When you receive the door at your site handling it in segments is usually more natural for workers used to traditional sized doors than and 4×8 materials than handling an extra large door. Leaving joining the door until it reaches the site cuts costs and saves time all the way form our factory to your building site.

Strong and Stable

Sing Core doors shipped in sections and assembled on site maintain the highest standards for strength, lightness, and straightness. At Sing core we guarantee warp-free performance of segmented doors for 5 years.

How to Assemble a Sing Core Segmented Door

Assembly of a modern sliding door constructed using Sing Core technology without any specialized tools and equipment.

1. Lay Each Panel Flat

The first step to join a Sing Core sectional door is to lay the panels on a flat surface. Any flat clean surface will work. For very large doors we like to use two straight beams laid on the ground along  to hold the top and bottom of each door segment.

2. Slide a Spline in to One Side

Each spline and pocket are precisely cut to fit with strength. Our products are built with our 5 year warp-free guarantee in mind. Simply push or lightly hammer the spline in place on one side of the joint. Then your panels are ready to be fit together.

3. Joining the Panels

The final step in joining a modern sliding or pivot door is to press the sides together. This can be accomplished a variety of ways, including gentle application of a sledge hammer, a few ratchet straps, clamps, or any other means you have of providing joining force. Once joined, the door is strong and secure, built to last, and can be finished and installed as any other Sing Core door.

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”).

Contact your door maintenance company and send them two photos.

c) [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.
