Large Sliding Doors

If you’re looking for the best large sliding door, you’ve come to the right place. Sing Core specializes in creating the ultimate sliding door experience. We manufacture the only door substrate that you can use to create the most extraordinary doors in the world.

The above picture is a demonstration of Sing Core’s strength.  Two 8’x9′ oak doors (approx. 800 lbs.) laying on top of two 7’x8′ curved doors.  The curved doors had no visible movement due to the high strength of Sing Core. As you can see, the eye plate is so small but can support such a large door panel.

 

These three curved panels measure 7’x8′ and are built to the highest precision and strength to last a lifetime.

 

Here is another example of a curved door with a smaller radius built with the exact same expertise.

 

Sliding Doors
The deal with sliding doors is that you want your sliding doors to remain straight and true throughout their service life. Architects, designers and end users face the issues associated with sliding doors, but rest easy knowing your sliding door has Sing Core inside.

Problems with Sliding Doors
The first problem with sliding doors is that they tend to move (warp, bend, twist or cup) compromising the doors’ performance. Especially in the case of sliding doors because they hang parallel to a wall (like sliding barn doors), next to another door (such as double sliding doors) or within a wall (like sliding pocket doors). If the door does not stay straight, it can wreck either the sliding doors or the surfaces they slide against, or both.

One way to overcome the warpage issue is to utilize stronger materials which tends to greatly increase the weight. The downside is that increasing the doors’ weight creates another set of challenge. For example, heavier doors require heavy duty hinges to support the doors. Heavier doors also require more labor for handling, installation, and any servicing it may require.

 

As you can see, this massive door is 8’x9′ and remains perfectly straight.  So straight, in fact, that it is perfectly freestanding on end!  If there was even the slightest amount of warpage, then this door would topple over.

 

Sliding Door Design Problems Solved
Architects and engineers are constantly perplexed with the problems associated with sliding doors, fortunately an Eco-friendly composite solution made in the USA, helps to solve the problems associated with faulty sliding door design. Patented Sing Core, along with their true flat door team, can help to create sliding doors that will remain straight and true far beyond the service life of any other sliding doors. By working with Sing Core’s design staff a combination of Sing Core and patent-pending sliding door stiffening solutions can create perfect sliding doors that are lightweight, high strength and can be guaranteed not to warp, bend, twist, cup or otherwise fail for 50 years.

These oak doors are manufactured with the highest precision.  As you can see, there is no gap between the two oak doors.  If they were slightly warped, or a little uneven, there would be a gap showing, possibly more.

The Perfect Large Sliding Doors
The best custom door manufacturers and millworks who offer long warranties on their large doors have a secret inside each one of their high end professional sliding doors: Sing Core inside. A properly designed and built large sliding door with patented professional Sing Core inside can be guaranteed not to warp, bend, twist or otherwise fail for 50 years.

How to Build the Biggest Warp-free Door

Sing Core has long been in the business of building the biggest warp-free doors in the world. And now you can learn how to build the biggest warp-free door as well. The first thing to note is that Sing Core does not build doors, even though Sing Core is credited and called out in architectural specifications as Sing Core door(s).

Inventor Peter Sing’s patent and patent-pending inventions are deployed in Sing’s Sing Core factory to provide the warp-free basis for high-end millworks and the biggest door companies for building big doors, over 8 ft. tall and up to 50 ft. or more, that can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.

New Door or Replacement Door

Sing Core assists in the building of either New Doors, doors that have not existed before, or Replacement Doors, doors that are being replaced and may have to be replicated to maintain the appearance of the original door, such as in the case of participating in a historical restoration.

How to Build the Biggest Warp-free Door

Since Sing Core does not build doors, it is up to the architect to imagine what size the new door should be and of what materials the door should be made of. In the case of replacement doors, Sing Core is provided all the specs based on the original door to be either replaced or replicated.

The following steps are followed in making a door with Sing Core inside:

Step 1: Answer questions, and estimate

  • What is the size (length, width, thickness) of the door?
  • How will you be finishing the door
  • What type of door hardware will be used (hinge, pivot, sliding, overhead, etc.)?
  • What style of door (flush, architectural, plank, French, Dutch, etc.)?
  • How and where will the door be used?
  • Will this be an interior or exterior door?
  • Are there other specifications (weight, insulation, sealing, etc.)?

Step 2: Re-evaluate and refer to Sing’s True Flat Team, if necessary

Evaluate your estimate and let Sing Core know if we can help meet your budget

The True Flat team is available to help you provide your customer with a door that fits within their budget.

Sing Core and the True Flat team can suggest ways of changing some of the details of the panel, such as, reducing the height/width or choosing a more cost-effective skin.

Steps might need to be made to modify Sing’s composite hybrid solid substrate to accommodate the challenges that may not have been noted in the original details gathered in Step 1.

Step 3: Manufacture specified Sing Core

The specific Sing Core substrate core is then manufactured in Sing’s factory by skilled workers who have been manufacturing Sing’s cores for years using Sing’s patented and patent-pending technologies. Occasionally, a new challenge is recognized that the true Flat Team has never seen before, that is when Sing get to inventing again, and when a solution is achieved, this will likely lead to another patented solution.

The core which is based on Sing’s insulated reinforced vertical grain torsion box core, may or may not be framed, and is sandwiched between two matching skins, ready to be used as door core.

If no other services are required, skip Step 4, and go directly to Step 5.

Step 4: Additional services

To further assist the millworks and door companies in the manufacturing process, Sing Core may provide other services. For instance, the millwork or door builder may elect to have Sing’s factory apply additional outer door skins to the completed Sing Core substrate, in a sense, creating a custom door blank.

Some of the additional services that Sing’s factory may provide, include:

  • Trimming
  • Adding exterior skins
    • Wood stave
    • Veneer
    • Cement board or concrete
    • High Pressure Laminate (HPL)
    • Fiberglass
    • Formica
    • Metal
      • Aluminum
      • Cold rolled steel
      • Copper
      • Galvanized steel
      • Hot rolled steel
      • Lead
      • Stainless steel
    • Impact/Bulletproof/Blast resistant materials
  • Light cutouts, openings, for glass inserts
  • Routing for architectural grooves

Step 5: Package and ship to millwork or door company

Sing’s factory packages and ships the door core or prepared blank to the millwork or door company who will finish the door.

Step 6: Finishing

Finishing takes place at the millwork or door company who installs hardware, finishes, and hangs the door, which is ready for installation.

Current Trends Don’t Wait

This is an update to let you know what the current trends are, here at Sing Core.

The biggest trend is this:

Warped Doors… Help!

We have been getting a lot of calls from professionals who have installed large doors who are now in trouble because those doors warped. As you know, Sing Core is the only way to build a large door that does not warp, and we guarantee it for 50 years.

If you are in trouble and need that door right away, we can do it for you, but you will incur rush fees. You will be far better off by getting the door assistance from Sing Core in the first place.

Don’t wait. Let Sing Core save you the headache, lost time, and expense of having to replace that high-end door later. According to the reports of incoming requests, the large doors are having to be replaced within six months of the job’s completion. Don’t let this happen to you.

We Can Do It

When you work with Sing Core to help you make that big door, you are working with inventor Peter Sing’s True Flat Team that knows how to build warp-free doors. They have years of experience with all types of building materials and types of doors. They know what can be done, what cannot be done, and have patented and patent-pending technologies to make an otherwise potentially warped door, warp-free guaranteed.

 

 

Ordinary vs. High-end

This is the difference between an average door and a high-end door: Precision over time. Out of the gate, Sing’s door core sports +/- .006 in. tolerance which is the highest precision door core to start with. That’s not including all the anti-warp technologies that are available to the team to make sure your door does not warp over time.

Built to Your Specifications

We can solve the issues that you are facing with your door. We can make the door lightweight, no matter what the size, but if you need to match a weight requirement, we can help you achieve that as well. Your door with Sing Core inside can be built according to your specifications.

Some Other Trends We Are Seeing

Grooved Doors

Architectural doors with horizontal grooves appear to be all the rage. If you have been doing this for a while, you already know that routing kerfs, plow cuts, furrows, or V grooves is compromising the door’s structure and may lend to increasing the door’s tendency to warp, but not if it has Sing Core inside.

 

High precision 1/16″ groove in 1/8″ skin

We can pre-cut grooves, even deep grooves (we have a special process for extra deep grooves) for you, without jeopardizing your non-warping guarantee. If you are doing a high-end job, you should start with a high-end core, like Sing’s warp-free door core.

Curved Doors

Unlike arched doors, curved doors must be very exacting to match the curve of the structure in question. The last thing you want is for that door to move, rendering the door unusable. This is extremely important for curved doors, that they keep their shape consistent over time.

Sing Core can match any curvature in your perfectly curved door and guarantee maintaining is shape in longevity. Nobody else can do that and guarantee it for 50 years.

CNC Carved Doors

CNC carved doors are really being seen as on the increase. These doors can be rather large, and you will need enough wood (meat) to carve into, and there are varying landscapes being carved into the grain, which is an invitation to warpage.

To prevent future warping doors, these CNC artisans are making sure they have non-warping Sing Core inside, specially designed and reinforced to accommodate both the natural wood grain and the varying depths being carved throughout the door’s surface area.

How Can We Do It?

How can we consistently make the doors that are impossible for other door manufacturers to create? Because it’s all we do. We have been doing it for years and will do it for many more.

We are not saying that other companies cannot provide their clients with 50-year warp-free extraordinary doors, because we work with the biggest and best door companies to assure that they can give this level of service and precision to their clients. They trust us with giving them what they need to deliver their best to their best clients.

Let us help you deliver the best big doors to your best clients.

Top 4 Ways to Make the Best Door with Sing Core Inside

Here are the top 4 ways architects are making the world’s best doors with Sing Core inside.

1. Check the Size
 

2. Check the Thickness
 

3. Check the Skin
 

4. Check the Sing Core Inside

1. Check the Size

Even the biggest doors, can save the budget and increase performance by making minor adjustments in the size. How tall? How wide?

2. Check the Thickness

How thick is your door? Increase a 1.5-inch door to 3 inches and enjoy 4-times the strength with a weight increase of as little as 5 to 10 percent. A little thickness can go a long way.

3. Check the Skin

Some door skin material is more accommodating than others, different wood species have varying degrees of challenges
Veneer. Very thin veneers are best laid on a very smooth layer of MDF for flawless hot pressing. You will find Sing Core inside the best high-end veneer doors.
Wood Stave: Wood stave skin is sliced and sanded from larger wood stock. We suggest 1/8th inch or 1/4 inch if cutting designs or grooves into the surface.
Paint Grade. MDF is again, an amazingly smooth surface to paint upon for outstanding paint grade doors.
Covered Plywood. Plywood can be covered in a wide variety of skins, such as fiberglass, vinyl, HPL, Formica, ceramic, or metals, such as aluminum, or steel.

See: Other Door Skin Types

4. Check the Sing Core Inside

Sing Core is not just one patented product, though it did start that way. The sing Core door solution now includes many different patents and patent-pending techniques that help to solve the problems facing architectural doors of any size or style, from door blanks to stile and rail doors. By making slight adjustments in the door’s measurements or other ingredients, you could reduce the cost of mandatory engineering and technology to keep the door straight, thereby reducing the overall cost of the door. This is the specialty of Sing’s True Flat Team.

How Are Architects Designing the Best Doors in the World?

Architects are the most discerning creators in the world because they desire to push the design envelope to the next level? One of the most dramatic impacts they can make on a new design is to apply their imagination to the structure’s first impression.

The project budget may not allow for a structural design that is so unique that anyone who approaches the project knows they are encountering a unique structure and experience based on the style of the structure. The next point of impact is the front door.

Sing Core empowers architects to create these one-of-a-kind creations that serve as the main entrance to the structure that represents their efforts to share their creativity and imagination with the world. See these Impossible Doors.

How to Design the Best Door in the World

Size Makes a Difference

A common approach to an architectural front door is to create a door of immense size. Architects understand that there will be issues with incorporating a huge front door. The first challenge they face is balancing issues associated with weight and strength.

Door Weight

Big doors are heavy. The bigger the door, the heavier the door. Big doors can be dangerous to install and can be dangerous to use. Large oversized heavy doors are expensive to make, handle, ship, install and maintain over time. Note: Door hardware is based on the weight of the door, a very heavy door, will require very heavy duty and expensive door hardware. (In some cases just the hardware will cost more than the door.)

Door Strength

At some point, as the door size increases, strength and dimensional stability decline. A very large door presents many challenges with trying to keep the door straight and true, so that it not only looks good but operates flawlessly over time.

Door Skin Makes a Difference

The exterior surface of the best architectural doors in the world presents their own set of challenges, whether they be exotic wood (natural wood grain, while it is beautiful, poses the most problem for potential movement due to the nature of the wood’s grain), hot rolled steel, or any other type of surface material.

Veneer

High precision veneering requires the smoothest surface for hot pressing, so we use our lightweight MDF which also has excellent adhesion. Thin veneers (like .030) can be very fragile and are susceptible to damage easily, so for high traffic doors, we suggest upgrading wood stave for strength and longevity.

Wood Stave

Wood stave is sliced and sanded from larger wood stock. We suggest 1/8th inch (1/8 inch compared to ¼ inch looks identical but less chance to move) or 1/4 inch if cutting designs or grooves into the surface. It can be challenging depending on the wood species and may require more Sing technology inside to keep warp-free.

Paint Grade

MDF is again, an amazingly smooth surface to paint upon. Assure your paint-grade doors are beautiful as you are coating them with high-precision finishing paint.

Covered Plywood

Plywood can be covered in a wide variety of skins, such as fiberglass, vinyl, HPL, Formica, ceramic, or metals, such as aluminum, or steel.

Door Thickness Makes a Difference

Managing a very thick moving door can present challenges, even more so if the door is very thin, and requires a great deal of engineering to make it stay straight and true over time.

Exterior Doors

Exterior doors are by far the most impressive and challenging architectural doors to consider, because they are used regularly, and one side of the door is exposed to opposing environmental conditions, increasing the door’s inclination to favor one side over the other, resulting in a warping condition.

Extra patented and patent-pending Sing technology is necessary to counteract these conditions, and therefore Sing’s True Flat Team must be aware of the conditions this door may be exposed to in order to have the necessary anti-warp technologies inside prior to manufacture or installation,

High Precision

When it comes to high precision, no other door substrate can compare to Sing Core. Go ahead and pull out your micrometer and measure for yourself. Sing Core sports the highest tolerances at +/- .006-in. If your job demands high precision, it doesn’t get any better than Sing Core.

Perfectly Straight

In the world, as we know it, there is no such thing as perfectly straight. The AWI does advise that there are tolerances allowed for straight non-warped doors, and the hardware manufacturers create mounting and articulating equipment to accommodate these specifications.

But this one thing we guarantee, that your door with Sing Core inside will be the closest thing to perfectly straight possible, and it will perform better than any AWI standard.

50-Year Guarantee

Your door, with Sing Core inside, can be guaranteed not to warp, bend, twist, cup, delaminate, otherwise fail for 50 years. No other door in the world can offer The Only 50 Year Non-warp and Structure Guarantee as Sing Core can.

Maybe you will agree with our clients who say,

“Sing Core is The Only Way to Build High End Large Doors.”

Impossible Doors Our Specialty

If you would like to know more about how to design a door with Sing Core inside, click here.

When it comes to building the most unique doors, especially large, oversized doors of any size (up to 20 x 60 ft. or more), type, or style of door, Sing Core’s True Flat Team knows how to bridge the gap between impossible and possible, by applying many variations of their patented and patent-pending technologies to make it happen. Some of our most recent projects include curved doors, Sing stile and rail doors, new patent pending Sing Core stile and rails, long-span wood stave planks, CNC door carving blanks, large sliders with man doors, billionaire home doors, and hot rolled steel doors.

When an architect’s visionary project is coming to life, it is common for the project to come to a halt when the main door (this inspired visual centerpiece of the project) presents problems for the millwork or door company in charge of the rest of the door schedule.

Oftentimes, the most common response is, “We will build it, or have it built, to your specifications, but this door will be placed on a separate rider, excluding it from any other warranty that may be covering the remainder of the door schedule.”

The door company will probably not even bother with the manufacturing of this piece, as it is too costly to re-tool to build it and it is likely to fail not long after installation. So, they will sub it out, and have an artisan millwork build it, freeing them from any responsibility for follow up maintenance calls regarding this piece of the job.

That is, unless they are working directly with Sing Core.

Many of the biggest door companies and high-end millworks are back into the specialty door business because they have partnered with Sing Core.

Why Sing Core?

Sing Core offers solutions that make impossible doors possible, and not only possible, but these magnificent works of art can be guaranteed not to fail, as they are covered by Sing’s

50-Year No Fail Guarantee

These enormous or one-of-a-kind unique doors are nothing short of amazing, with unparalleled service records and longevity, and they are guaranteed not to warp, bend, twist, cup or otherwise fail (including full structure and lamination warranty) for 50-years. No other door in the world comes with such an impressive guarantee unless it has Sing Core inside.

The Most Unique and Challenging Doors

Large doors are not the only unique and challenging doors to come to the attention of the True Flat Team. Many other types of architectural doors will present a huge list of problems that will send door engineers, designers, and custom door makers running for cover, yet they are no problem for the Sing Core factory teaming up with the sophisticated door manufacturer or millwork to accomplish. Like these:

Curved Doors

Curved doors are unique specialty doors, that require precise curvatures, especially if they are being newly installed in a pre-existing wall or structure that is curved. Matching the curvature of the door to the existing wall can be extremely difficult, but the True Flat Team at Sing Core make the perfect curved door to match any curved wall or structure, while still guaranteeing the door for 50 years to perform without warp.

Sing Stile and Rail Doors

The Sing-style of stile and rail door is a departure from traditional stile and rail door technology. The clients who prefer the Sing-style stile and rail door are looking for characteristics that are unavailable via traditional door building methods but still retain the look and feel of a traditional stile and rail door. Specifically, they are looking for a stile and rail door that is impact resistant, insulated for both sound deadening and climate control, and of course guaranteed for 50 years. Sing Core accomplishes this by building the stile and rail face on top of a patented warp-free core.

 

Large Thin Stile and Rail Framed Doors

Sometimes the architectural door specifications are unusual, like this wood-framed traditional stile and rail door with a large glass lite opening. This is a 14 foot tall door that calls for only a three-inch wood stile and rail surround to hold the glass. This is unusual and would be hard to accomplish with standard door building methods, and it was even a challenge for the True Flat Team, which led to their creating a new type of stiffener, which is now patent-pending technology. Now, standard stile and rail doors made with Sing Core stiles and rails can be guaranteed to remain warp-free for 50 years using new patent pending Sing Core stile and rails.

20-ft Span Wood Stave Garage Door

This is just one example to the many kinds of garage doors that Sing Core has helped to make possible. In this case, the architect insisted on 20-ft spanning warp-free wood stave planks, that any other way would have been impossible. 50 years from now, will be just as straight and true as freshly installed thanks to Sing Core and their long-span wood stave planks.

CNC Carved Doors

These beautifully CNC carved doors would be impossible to keep straight as they are accentuating the wood’s natural grain which is already trouble brewing, if not for the warp-free Sing Core working hard behind the scenes, deep inside to keep these doors perfectly and truly flat even though they are 107-inches tall using Sing CNC door carving blanks.

 

Large Sliding Doors with Man Doors

When it comes to large sliding doors with man doors, there is really only one way to do it with a high degree of precision. The large sliders with man doors must remain decidedly straight and true in order for the man door to operate seamlessly, plus, because there is Sing Core inside, you get the added benefit(s) of getting lightweight, high strength, fully insulated for sound and climate control, and our 50-year warp-free guarantee.

 

Billionaire’s Exotic Home Doors

These massive natural teak doors have Sing Core inside to keep them from warping and also to provide added protection from outside interferences to privacy and the elements. Not everyone can have their whole homes fitted with Sing’s doors, but what a great feeling it is having done so with Sing’s billionaire home doors.

 

Hot Rolled Steel Doors

Hot rolled steel doors can be a challenge, especially if they are very large. Normally, large hot rolled steel means a lot of weight needs to be articulated adding stress and strain to the frame, hardware, and structure if used very often. Patented and patent-pending Sing Core reduces the weight greatly while enhancing the door’s characteristics enabling one to install a man door or open and close a mammoth-sized hot rolled steel door easily.

 

When Bigger is Better

Thanks to the patented and patent-pending technologies in the hands of the True Flat Team at Sing Core bigger does not necessarily have to mean heavier or big troubles are ahead. With Sing Core inside your big doors can be lightweight, high strength, fully insulated, and guaranteed warp-free for 50 years.

How to Build the Best High-End Stile and Rail Door

Being in the business of helping the biggest door manufacturers and high-end millworks building the best doors in the world, we thought we might let you in on a little secret. Sing Core is world renowned for building the best enormous doors that are lightweight, high strength, fully insulated, and guaranteed to perform warp-free for 50 years. But did you know that we also make the world’s strongest lightweight and insulated stile and rail doors?

The popularity of stile and rail doors has been around for years because, number one, they look amazing. They have a unique appearance as they are manufactured of panels of various sizes. The most popular, and it is the one you are most likely to think of when you think of a stile and rail door, is the six-panel door.

Hands down, this is by far the most popular design. The traditional six panel door is made up of 15 individual wood pieces with alternating grain orientation and all the components are assembled by varying means depending on the application of the door.

If the best feature of the stile and rail door is the undeniable appearance of the door, the second-best feature of the stile and rail door is it’s ability to stay relatively straight over the life of the door. This is accomplished by varying the grain orientation of all the individual panel pieces, which push and pull against each other, unlike a traditional solid slab door which can move wildly at any time or according to any change in the environment.

But the biggest disadvantages include very low insulation value. This means they are not well suited for climate control or sound reduction, and for high-end clients, though they love the appearance of the panel doors, they are not very strong.

If you build stile and rail doors, you may need to know how new technology can lower your labor costs and increase your productivity when building all types, styles, and designs of doors. Sing Core has done it and proven it backed by the best guarantee in the industry.
We can help you:

  • Meet your production needs – Fast Delivery
  • Exceed your quality expectations – High Precision
  • Reduce your labor cost – Money Saving
  • Structural guarantee – 50 Years!
  • Custom sizes – Any Size or Weight
  • Fully insulated and sound deadening door panels

The Sing solution is to build your stile and rail door on top of the patented Sing Panel Door Substrate invented by Peter Sing. Sing’s substrate is lightweight, high strength, fully insulated and comes back by the only

50-year Warp-free Guarantee

in the door industry.

Now, you do not have to settle for a weak stile and rail door because your stile and rail door can have Sing Core inside.

How to Build a Stile and Rail Impact Door

The first step is to start with Sing’s patented core which is built of small metric vertical grain torsion box where the voids are filled with foam for insulation, and this is sandwiched between two stress skins.

The next stage is where the expertise of the millworks and door manufacturers come in. Instead of manufacturing the door out of individual pieces of wood stuck together, the panel design elements, as in our six-panel door option shown here, are added to the surface of the door.

This gives you the appearance of the traditional six panel that we all have come to love, but if your six-panel door has Sing Core inside, you have the lightweight for panel doors of enormous size, or adjustable weight for smaller doors, with all the insulation and incredible unbreakable strength.

Sing says, “If you kick a traditional stile and rail door you will break the door, but

“If you kick my door, you will break your leg.”

(Don’t try this at home.)

This is just the beginning. Sing can help you make any kind of door. Sing Core is featured in all kinds of doors and is highly sought after when creating replacement doors is historical restorations, especially if they are large doors which are problematic for maintenance because they do not have Sing Core inside. We do not sell our products to homeowners, door stores, or door shops. We do not sell our products to general contractors without door finishing facilities or capabilities. We mainly deal with door manufacturers and millworks which have experience to build high-end doors.

Problem Solved.

Did you know you can get your custom super large door substrate in 1 week? It’s true, thanks to inventor Peter Sing’s patented and patent-pending large, oversized door core technologies and his factory that is 100% dedicated to manufacturing nothing but large doors for you and your clients, you can get these enormous door blanks created in as little as 1 week. This is an unprecedented turnaround time and also comes backed by Sing’s full warp-free and structure guarantee for 50 years. You won’t see an offer like this anywhere else in the door industry.

Are You Getting Tired of Being Disrespected and Given Long Lead Times for Big Doors?

 

Now you don’t have to wait around for long lead times, as much as seven or eight months to get going on your project when you are waiting on the most important part, that big door.

How Sing Core is Included in Your Project

Often the Architect specifies Sing Core in your challenge, large, curved, arched, or specialized surface skinned door. In other cases, the door manufacturer or the millwork building the door says,

“There’s only one way to make this door: 

with Sing Core inside.”

And they are right. Peter Sing’s inventions are the only known methods of producing a lightweight, high strength, fully insulated door blank that will not warp, bend, twist, cup, delaminate, or otherwise fail, and can be guaranteed to remain fail-free for 50 years.

Can I Get a Door from Sing Core?

Sing Core does not make doors, but we help door manufacturers and millwork make the best doors with our patented and patent-pending technologies as the foundation.

The Door makers use our substrates as the base material to create their one-of-a-kind works of art that our clients have learned to appreciate and enjoy. It takes a concerted effort of Sing’s True Flat Team, assisting in the design and creation or the door and the highly skilled door builders and millworks to finish and bring these beautiful doors to life.

What Does Sing Core Do?

We provide the lightweight, high strength, non-warp door blanks with fast delivery so your big door does not have to hold up your production time. Our True Flat Team helps to design the core material from the inside out, takin into consideration all the specifics necessary to create a warp-free door.

What Does Sing Core Need to Know?

There are many details about the door that go into the building of the door’s substrate that Sing’s True Flat Team needs to know before they can go about building the substrate. First, and most obvious, is the size of the door. Doors over 8 ft. tall start to introduce challenges into the design. Then there is the door type. Will it be a pivot door, hinge door, sliding door, or other type of door? Where, geographically, will the door be installed? Will it be an exterior door? Will it face the elements or be isolated? What surface material is desired (some provide more challenges than others), and much more. With data in-hand the team can develop a warrantable substrate.

How Fast Can Sing Core Do It?

We can have your custom substrate ready for the manufacturer to finish in as little as 1 week, and we answer this call by clients who would rather not wait for our standard turnaround time which is four to eight weeks.

What Does the Door Mfg. Do?

We provide the fail-free door blank to the manufacturer (door builder or millwork) who cuts lite openings and hardware access locations in the door, installs glass if specified, hardware, finishes, and hangs the door. The door manufacturer or Sing Core (or a combination of them both) may be responsible for applying the final layer(s) of skin material.

How Easy is it to Get a Price Quote?

It’s as easy as 1, 2, 3. Within minutes you can submit a price quote for your specialty door, and instantly see a 3-D graphic or your proposed door and a preliminary architectural drawing of your door instantly. All you need is the length, width, and thickness of the door you want and what skin you would like to see on your door. (See How to Order and What to Expect)

How Can I Get a Door with Sing Core?

The easiest way is to have your architect specify a Sing Core door in your project. Other ways include contacting your custom door manufacturer or millwork and requesting that they build your door with Sing Core inside.

Can You Guarantee Any Door for 50 Years?

Unfortunately, we cannot guarantee any door for 50 years. If the door cannot be built to specs and guaranteed for 50 years, we will not participate in the building of that door in that respect. But if the architects, designers, and engineers can work with Sing’s True Flat Team, with a little re-engineering and ingenuity, it is highly likely that Sing Core can help to produce a door that can be guaranteed for 50 years.
