New Modern Panel Doors

Panel doors are a longstanding stylistic type of door which has withstood the test of time. One of the best features of the panel door is its potential to stay straight and not warp. In the traditional manner of building a stile and rail panel door is to use many pieces of wood with grain orientation in differing directions to help counteract wood’s potential to move. Sing Core is proud to bring you the New Modern Panel Doors.

New Modern Panel Doors

Many faux styles of panel doors have been approached, for instance molded door skins made of plastic, fiberglass, or vinyl where the style of the traditional panel framing is 3D molded into the face material. What you get is a weather resistant door that looks like a traditional panel door.

New Modern Panel Doors

Enter new modern panel doors, the next generation in panel doors that are far superior to other panel doors of any kind. Unlike traditional panel doors, new modern panel doors are fashioned of a superior flush or flat panel door with 3D molding added to the surface material as decoration, to imbue this door with the visual characteristics of a traditional panel door.

What makes new modern panel doors superior to traditional panel doors?

New modern panel doors have Sing Core inside, which means they are Eco-friendly, extremely strong, lighter in weight than other panel doors, and fully insulated for increase sound dampening, and climate control. All impressive attributes, but the most impressive are that these doors are the very same doors that are considered the best doors in the world, and are the only doors that come with a 50-year warp-free guarantee.

Inventor Peter Sing is responsible for making his patented Sing Core available to the biggest and best door manufacturers, millworks, and custom door builders in the United States. Sing’s patented core helps make possible the building of extremely large doors lightweight, high strength, fully insulated, and warp-free for 50 years. That is why you find doors with Sing’s core inside anywhere from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.

Sing is patenting these new modern panel doors which include his patented core inside complete with panel enhancements to make this new generation of panel door appear to be a panel door without any of the negative side effects.

What are the less than desirable characteristics of a traditional panel door?

1. Panel doors are weak

Kick a panel door at nearly and juncture where two or more panels meet, or a stile or rail, and the door will collapse and fall apart with an average degree of force. In comparison, Sing says, “Kick my door and you will break your leg.”

2. Panel doors are not insulated

Panel doors are made of wood. Just wood. Which is pretty but only has an R-factor or R1 to offer as insulation resistance, while doors with Sing’s core inside host R3.5 or more per square inch, depending on the insulations specified in the door.

3. Panel doors are heavy

As they are made of wood, wood is very heavy, so any door you make with only wood will reflect your choice in materials in the overall weight of the door. Doors made with Sing Core inside weight a fraction of solid wood doors but look like solid wood thanks to Sing’s patented hybrid composite core material.

Now you can have a door that is every bit as elegant as any traditional panel door that can be guaranteed to stand the test of time while providing high precision (+/- .006 in. tolerance) and high performance (50-years fail-free service) in an Eco-friendly, lightweight, high strength, fully insulated door, thanks to Sing Core.

No other door in the world is backed by a

50-year Warp-free Guarantee

Unless it has Sing Core inside.

Hot Press Veneer Professionals

Hot Press Veneer Professionals are More Successful and Profitable with Sing Core

For years, Sing Core has been providing high-end local and nationwide hot press veneer professionals with premium core material that eliminates the need for crossbanding.

Let’s face it, nothing can compete with the beauty and elegance of a perfectly hot-pressed panel, and for that sweet-spot in the marketplace, those clients that demand the best and are willing to pay for it. The manufacturers and millworks that have Sing Core inside their hot-pressed products are making bank by specializing in these ultra-high-end projects.

For general contractors, we recommend using your local millwork to lay veneer, as it requires a skilled professional.

From the Inventor of Sing Core

Sing Core Inventor Peter Sing

Sing Core Inventor Peter Sing

I get asked by hot press veneer shops, if we are in competition with them? And the answer is, “No.” Even though we are specified by architects all over the country in large veneer projects, and mostly in huge veneer doors, we do not do the veneer. What we do is to provide our substrate to the best hot press veneer professionals we know. If a contractor contacts us first because we were spec’d on the job, we have him tell us which veneer company he wants us to work with, and my team is willing to help match up the best material and veneer services if they ask us for their advice, and that’s what we do.

I have invented patented and patent-pending solutions for high precision veneer projects that take the pain out of the challenges normally associated with big, long-spanning high-end jobs, anywhere from the San Francisco MOMA to the top of the World Trade Center’s Freedom Tower.

The top reasons the architects specify Sing Core is because

  1. We use only the best hot-press veneer companies to apply the best veneers, because I understand that doing veneering really great is an art, and we suggest only using the best artist, as you would on any important project.
  2. My company does what we do best, that is to provide the best substrate for veneer specialists to lay high quality veneer with the best guarantees in the woodworking industry.
  3. The people and companies that I work with are the best in their field and they don’t have to worry anymore about if this will work or how to solve problems associated with weight, dimensional stability, warping, or long lifespan. We’ve spent years in R&D to make sure that the biggest doors in the world do not have to warp anymore, and the biggest door companies trust me to make it so. In the last 10 years, they have not reported a single failed door, even including doors of immense size. Not one.
  4. My core is stronger than steel pound for pound and less than 1/3 the weight of doors made of solid wood core. Sing Core provides a high precision strong full bonding surface for veneering to that is so smooth crossbanding is not required. How high precision? Try +/- .oo6 inch, compare that to any other core material.
  5. Sing Core has insulation for enjoying warmth in Winter and cool Summers, is sound deadening for peace and quiet, and more dimensionally stable than other type of core such as foam core, honeycomb core, wood-based core.

You may not see everything we do because it is hidden deep inside the door or panel, but it’s there and many people can sleep soundly at night knowing that we have done all the hard work in advance, so that you don’t have to worry about endless maintenance calls.

I am so proud of my invention, that I put my name on it: Sing Core

What makes a hot-pressed panel worth so much more with Sing Core inside?

Architects are increasingly specifying their large high-end hot pressed veneer panelized walls, features, and doors have Sing Core inside (accounting for about one-third of all our products which are sent to the greater New York-area). The contractors generally contact Sing Core directly first, due to being specified. Though Sing Core does not actually do the veneering. Sing Core provides the high precision substrate that is shipped 3,000 miles from the manufacturing location in Washington State, to the high end millwork in New York (or wherever the nearest hot press specialist is near the construction site) to do the veneering there.

You will find Sing Core inside high-end hot pressed veneered ceilings, walls, floor, and doors in the most demanding architectural designs and projects.

Why?

Why must architects and designers go through such an unusual process to meet the needs of these high production and precision projects? According to those who are specifying and using Sing Core in their projects,

“There’s just no other way to do it.”

Large Size Concept Consideration

In an age when the biggest projects often include large spanning surface areas wrapped in beautiful wood veneer, the large scope of such a project is problematic. You are dealing with immense spans of material which is difficult to maintain straight and true, because at that size, most material will begin to move with changes in temperature, humidity, or other environmental variations. Sing Core is the only known method of keeping these spans straight and true. That is why the biggest door companies use Sing Core inside their doors that are over 9 ft. tall, because it doesn’t take much movement in a large door to render it inoperable. Then you do not have a door, you have an obstacle, or a bowed wall that needs to be dealt with. This leads to Sing Core’s primary function in these huge projects,

Warp-Free Hot Pressed Veneer

Particularly in high-end designs featuring the beauty of hot pressed veneer, the last thing you want is your project to express variances or changes. The desire is to have a completely flat surface that can span great length without warping. This is what Sing Core provides. It is the reason large doors (even extremely large doors) are guaranteed not to warp, bend, twist, or otherwise fail for 50 years, because they have Sing Core inside.

Highest Precision

High precision is a sought-after attribute of some of the most demanding clients, and Sing Core’s high precision (+/- .006 tolerance) gives them the high end performance that your clients are willing to pay extra for.

Lightweight Veneer Panels

Hot pressed veneer panels with Sing Core inside weigh less, not much more than a hollow core panel, but feature a fully insulated warp-free solid hybrid core that is 100% surface-area bondable.  We do not provide hardware or veneering.  If asked to lay veneer, we subcontract out to the best veneering professionals.

100% Surface Bondable

That means, no weak spots like you might see in honeycomb-type cores, which offer only 10% or less surface bonding area. This full-bonded surface area inside the panel eliminates delamination over time.

Fully Insulated Veneer Panels

The insulation value is important in high-end hot pressed veneer applications for both climate control and sound deadening capabilities within expansive structure designs.

Less Expensive to Deploy and Install

Keeping these hot pressed veneer panels lightweight translates to less expensive shipping, handling, and hardware. They are easier to and less expensive to transport, manage and install on site with fewer risk of injuries, even if the panel is exceptionally large.

 

 

50-Year Guarantee

The non-warping hybrid core allows large door companies to build large doors that can be guaranteed not to warp, bend, twist, or otherwise fail, including delamination.

We Do Not Veneer

We always recommend using your local veneering professionals for custom veneer doors. We do not provide veneer or install it.  It is our policy to subcontract veneering jobs to the best veneering professionals in the USA.

If you offer hot-pressed veneer services or cold-press veneering to your clientele, your highest paying customers will gladly pay you more if your panels have Sing Core inside.

The Best Sliding Doors

Sliding doors are the perfect way to complement to your home’s individuality. Sliding doors are ideal for smaller spaces, due to their space saving nature. Some sliding doors even slide completely out of sight and into the interior of the adjoining wall. These doors create a pristine and merely seamless entrance to any room. We are glad to provide you with the best sliding doors in the industry.

Sliding doors consist of one or more door panels that open by either gliding on a track or hanging from rollers mounted above. This style of door is very sensitive to weight, as the entirety is often hanging from the top of the door jamb. If the doors are too heavy, this can cause some serious and potentially dangerous issues. Sing Core have the solution to these issues.

Traditionally built sliding doors have a tendency to warp over time. That may not seem like a big deal, but it can make the door fall from its track. It is very dangerous when this happens especially when someone is nearby… Ouch! Whether your sliding door is a patio style door or a sliding closet door, its best to have it lightweight and truly flat for the entirety of its lifespan.

WE HAVE YOUR ANSWER

Pivot Doors in Luxury Homes

Pivot doors are among the most popular door we get requests for. Pivot doors in luxury homes are very common and are often over sized. Over sized is anything over the standard 3’ x 7’ door size. We supply the most high end and high precision doors to luxurious homes all around the world.

No one can do what we do.

For those who are not familiar with pivot doors-

Instead of the doors motion being controlled by traditional hinges, a pivot-hung door swings on a set of pins mounted in the top and bottom. The pivot door rotates on a pivot box in the floor and the top jamb rather than traditional door side hinges. This creates an elegant masterpiece that rotates effortlessly and usually no hardware is visible, except for the handle of course.

 

Pivot doors have many uses and can come in many different sizes. It is most popular to have over sized pivot doors that provide generous openings, but it is not necessary. Pivot doors are most commonly used as exterior doors, giving a beautiful and grand entrance to a home. They can also be used for interior doors. Whether it is to the bedroom, bathroom, or even laundry room pivot doors can add an elegant entrance to any room of your home. You could even have pivot doors for your closet!

 

We can make any size pivot door you may need and our doors are always built with the highest precision. We have perfected our craft so much that our tolerances are always within ±0.006”.
Our pivot doors are exceptionally lightweight, high strength, and always dimensionally stable.

 

Here at Sing Core, we always get requests for pivot doors. The majority of them are over sized. People from all over the world come to us with doors like this because we are the only door company who can make door of this magnitude last for many years. That is why we offer our-

Breaking News: Thin Doors Need Strength Too

Breaking News: Thin Doors Need Strength Too!

Sing Core has always been on the leading edge of the reinforced structural panel industry.

Our panels are among the lightest, strongest, and overall best on the market.

Watch the video below and hear how solid our doors really are.
 



This panel is super thin for its overall span. Overall thickness is only 1 3/4″. Our patented torsion box honeycomb allows us to create lightweight high strength panels that can be any size without any warping. Solid wood would be very heavy and can potentially warp shortly after being produced. This panel is a whopping 65 1/2″ x 120″ and only weighs 139.6 lbs.!

As you can see, the skin is birch plywood that is less than 1/8″ thick. Combined with our torsion box honeycomb design, this panel will be stable and remain rigid for many years.
Due to this panel being truly flat, it can stand alone on edge. If there was any deflection, the panel would be unable to balance.

Thin oversized panel standing on edge. 

 

Can any anyone else achieve this?

 

 

Let us know!
If not, share this with a friend who may need our patented technology.

 


<tbody=”border: none;”>

A door with these dimensions is greatly feared by many door manufacturers. A door like this is nearly impossible to build without having issues. Common issues with doors so large and so thin include warping, delamination, prevalent weak points, and many others. If this were produced with solid wood, the door would be unable to stand alone due to not being true flat. Sing Core’s true flat doors and panels comply with AWI standards and can stand alone.

Sing Core’s patented lightweight and high strength torsion box honeycomb core design makes building oversized doors easy and provides lasting strength and durability. We know our doors and panels are among the lightest and strongest on the market, so we guarantee every door and panel for 50 years!

We never do veneering in house. We only trust local professionals for veneering services. Sing Core only provides substrate to be veneered. We highly recommend using your local veneering professionals. Veneering requires highly trained professionals to ensure a quality finished product.

Our substrate with MDF is very good for hot pressing as well as preventing telegraphing in the outer skin. This is the best option for ensuring a quality veneered door panel. With Sing Core substrate and 1/8″ MDF, no cross-banding is required. MDF is a very stable substrate to use.

For other applications, plywood is very strong and provides the best dimensional stability. This is the best option for applying overlays, such as wood staves, drywall, concrete board, etc… We offer many different plywood options, see our skin type page for more information.

Secrets of Warp-free Large Sliding Barn Doors Revealed

Large sliding barn doors are an important feature in the biggest warehouses and industrial locations in the United States, from military to aerospace a big sliding barn door is often specified in the architectural designs for practicality and ease of use. But the larger the door opening the harder it is to keep these huge sliders from warping. If you cannot keep the door straight, you may have reduced access due to door failure.

Ceiling mounted barn doors 14 ft. x 3.5 ft. x 2.5 in.

For years, inventor Peter Sing’s patented warp-free sliding barn door solutions have been the answer to these massive sliding barn doors, which using his patented and patent-pending anti-warp solutions can be built lightweight, high strength, and be guaranteed not to warp for 50 years, unheard of before the invention of Sing Core.

Interior Barn Doors

As interior design has evolved, the integration of interior modern barn doors in everything from residential to commercial projects has seen rapid growth. Of course, standard-sized interior sliding barn doors do not pose much of a challenge, but if the door exceeds 8 feet tall or a 4-foot width, now you are heading into dangerous territory if you are hoping for a non-warping sliding barn door.

Commercial Steel Barn Door

Warped Large Sliding Barn Doors

Regardless of the application, large sliding barn doors are going to be problematic, so much so that years ago, the biggest door companies in the USA excluded offering the large barn door from their door schedules, instructing contractors to seek out custom door makers or millworks, because they could not cover these enormous sliding barn doors with any warranty because they were destined to warp and fail not long after installation.

After a while, even the millworks started turning down jobs for large sliding barn doors for the same reason, too many service calls during the warranty period, though this did open a door for door service companies whose job it was to regularly maintain doors, though this was extremely expensive for end user of the warping big sliding barn door.

Not Faulty Design

The problem, it turns out was not with the design, as large sliding barn doors were both stylish and practical, so the architects could not be blamed. The problem is with the limitation in building materials. A dimensionally stable door could be made of a thick solid material such as solid steel, but the bigger the door gets, even solid steel will move according to changes in the environment. Sing is able to bring the ideas of the architects and designers to life in such as way as to provide a 50-year solution to such visionary ideas.

Warp-free Solution

When inventor Peter Sing introduced his warp-free technologies to the large sliding door companies, they embraced Sing’s solutions for warped large sliding doors. Thanks to Sing, they were able to get back into the oversized door market once again. According to them, in their own words. Sing’s core,

“Is the only way to build a lightweight warp-free large door.”

The only way.

Commercial Steel Barn Door

A Door is Not a Wall

It is important to learn what the core structure is made of. Doors are not the same as walls. Doors need to move repeatedly everyday while walls are permanently placed. Walls commonly use 2” x 4” framing methods which do not work well for building doors. If the structure of the door is not strong, it will not feel or sound very solid. When you close the door, there will be rattling sounds and/or it can deform over time. It is very easy to tell, all you have to do is close the door and hear how strong or solid the door is made. It may look the same, but it does not sound the same. You can tell the difference by knockings on the door, you can tell what is inside. Solid like a rick but still light like a feather when you swing the door closed. The structure of the door that makes the difference, not the door skin.

You Want a Warp-free Large Sliding Barn Door

We already know you want a large warp-free sliding barn door. How do we know? Because Sing’s email servers are filled with people asking about how they can get a sliding barn door with Sing Core inside? Unfortunately,

Sing Core Does Not Sell Doors

Even though sliding barn doors with Sing’s core inside are among the best doors in the world, Sing’s factory does not build doors. Rather, they provide the raw warp-free base materials to the door building companies and millworks who create the enormous warp-free sliding barn doors, that the inventor is credited with, even though Sing only provides the base material. So, if you really want one, just contact your favorite door builder or millwork and tell them you want a door, “with Sing Core inside.”


What is the Secret?

How to Build a Large Sliding Door

Undoubtedly, you have wondered how does Peter Sing build such large lightweight sliding barn doors that are stronger than steel pound for pound and can be guaranteed not to warp for 50 years? Following are the methods that Sing uses to build warp-free doors of any size, made of nearly any flat building material, secrets revealed.

First, the architect or door engineers, specify the door dimensions and the material that the door will be made of, and submit the specs to Sing’s True Flat Team. The team goes to work, gathering all the data necessary to predict what the challenges will be for the door. Questions like, will it be an interior or exterior door? Will it be exposed to the elements? In what geographical location will the door be installed and at what altitude? Which direction will the door face?

The team starts with Sing’s patented rigid foam reinforced torsion box core, then add additional patent-pending anti-warp technologies to compensate for exterior door skins and environmental concerns.

That is the secret inside these huge warp-free doors.


How Can You Ship Such Large Doors?

Of course, the military can do amazing things with transportation that cannot be accomplished by mere mortals, so Sing has created a modular technology that supports his 50-year guarantee. In this manner, any size of door can be built and shipped in high precision sections that are assembled on-site.

Joining a modular door shipped in sections

This saves so much on shipping and handling costs, and if the large door needs to fit in an elevator or tight doorway, not problem. High precision modular solutions are the answer. Sing Core has built many large doors that are joined on-site without any warping.

Don’t try this at home. Average dowels and even larger biscuit-joining will not prevent door warping. Let’s say you wanted to build a pair of 10’ x 20’ double barn doors that were 2-inches thick. Stacking and joining four 5’ x 10’ x 2” panels together will not be an easy task. But Sing Core has had many years of experience with oversized doors, and has been devoted to solving the common issues with larger modular doors.

If you have a good budget, high precision demand, and no issue accessing the job site then a one-piece large door panel is the way to go, if it can be shipped to your location.

Otherwise, modular door sections joined on-site will be the best option. There are two major factors to achieve high quality when building large doors. One is to make sure there is no warping once the modular sections have been joined. The second issue is maintaining a high precision joint line so that it is not noticeable. This requires a very high precision core to achieve. Sing Core is the most precision door core available, with a tolerance of ± 0.007”. It is important to be sure that the thickness of the core is within these tolerances.

Weight and Strength

Strength plays a key factor when building larger doors. Traditional door building methods may dictate that strong doors are heavy and lightweight doors are weak. Weight is a major issue with oversized doors. Heavy doors are significantly more expensive due to additional structure costs, higher labor costs, and extra shipping and handling costs. Heavy door core does not mean that it will have high strength and the larger the door is, the more strength is necessary to maintain a long lifespan.

When using Sing’s metric interior technology where every two inches is mitigating the potential of the exterior surfaces to move two to three inches at a time. Rigid foam insulation is used inside these small torsion box grids made of vertical grain natural wood fiber which pushes and pulls against the surface material’s tendency to move, keeping it straight when it would otherwise warp. It also provides a huge weight advantage over any other method of trying to keep a door from moving following installation.


What type of skin is best to build a large modular door?

Paint Grade – It is easy to hide the seams. Seams can be almost unnoticeable if modular sections are joined with a Sing Spline. If the spline is made of solid wood, it can move or warp after the moisture levels change and it will be reflected on the surface of the door. This can cause the surface of the door to crack after the seasons change.

HPL (High Pressure Laminate) – See how precise the joint is using only a Sing Spline. HPL is available in a wide variety of patterns. The best choice for HPL is a vertical pattern to help the joint blend into the surface. HPL is a good choice when ordering one of our modular oversized doors. The patterned HPL allows the joint line to be hidden in plain sight. The door can be as big as 12 feet tall and 40 feet wide without having any noticeable seams.

Metal – If it is paint grade metal, the seam can be filled with joint compound and then painted making a seamless joint. Metal doors are traditionally very heavy, but with Sing Core inside your metal door can weight roughly 1/3 of a traditional metal door. You can choose from any type of metal you would like, but our most commonly made metal doors are Aluminum or Cold-Rolled Steel. Click here to see a paint grade Sing metal door.

FRP – FRP, or Fiber-Reinforced Plastic, can be used to make very large doors and very durable doors. FRP can be smooth or have a textured surface. It is much more visually appealing and functions much better than solid wood which has potential to crack, warp, twist, and cup. Besides, solid wood weights a lot more than Sing wood stave planks. Sing wood stave planks are the ideal material to replace solid wood for such jobs as, doors, tabletops, post and beams, and many more. An advantage of choosing wood staves are that they are much more precise than solid wood because their tendency to move over time is minimal in comparison. On the other hand, wood staves are much harder to match with surrounding patterns than a wood veneer skin.

Wood Veneer – Wood veneer has an average thickness of 0.020″-0.030″ and is very difficult to hide joint line in the face of the panel. Wood veneer is often much more challenging because it is usually very thin, normally only 0.020” thick. We always suggest using thicker wood staves which are usually 0.125” thick rather than veneer. However, Sing Core has a proprietary technology to make a veneer panel seamless as large as 10′ by 16′. This requires the veneer to be staggered and hot-pressed. It is very costly to use veneer, oftentimes we use wood staves to build larger doors.

For a tighter budget, we recommend using a paper backed veneer which only requires being cold-pressed. Sing Core provides the smoothest MDF skin for our clients to hot-press. Cross banding is not required with our smooth and high precision substrate, which may be hard to believe for some people. We have been doing this for many years with our innovative technology. We always recommend that our clients purchase our veneer substrate, complete with the same warp-free guarantee, and hire your local veneer contractor or do it yourself to save some money. One advantage to using a wood veneer as the skin for your door panel is that veneer can be easily matched to the surrounding area. One disadvantage to using wood veneer skin is that it is not well suited for exterior purposes, such as entrance door, and it can be difficult to repair if damaged. Veneer skins are the also limited to the maximum door size of 10′ by 16′.

Invisible Doorway

Hidden “Jib” Doors

A door that is hidden in plain sight is commonly referred to as a “jib” door. Jib doors can often be called invisible doors or frameless doors. This type of door traditionally sits flush with the wall and matches any pattern on the wall. Jib doors provide a camouflage entrance to “secret” rooms. Everyone loves a house with a hidden door or secret rooms. We can provide jib doors, concealed cupboards and riser door systems perfect for concealing unsightly riser doors, access panels and service cupboards.

Essentially, it’s a door that is flush-mounted right into the wall—and often without hardware—essentially making it “invisible.” Sing Core provides lightweight and high strength door panels. These panels are crafted with the utmost precision. Sing Core’s door panels are comprised of a specially designed torsion box honeycomb core. This special design prevents warping, even in greatly over-sized doors. Sing Core is one of the only door companies who can guarantee their doors for 50 years. No other door company can make this claim!

Known for their essential “invisibility,” jib doors are flush-mounted directly into the wall allowing them to blend beautifully with their surroundings. The most subtle jib doors often lack any visible hardware. Bookcase doors work perfectly as entrances to panic rooms or vaults for storing firearms, jewelry, documents and other important items. A jib door is nearly invisible, or at least disguised from being recognized as a door. It may have the same moldings or wall treatment as the surrounding wall, creating a door hidden in plain sight.

What is the purpose of a jib door? A jib door or set of jib doors allow you to disguise that old broom closet so no one would even know it is there. Jib doors are very popularly used to keep precious valuables safe and secure. More importantly, jib doors can and are used to conceal your home’s panic room. A jib door is only hidden as well as it is made precise. Do not take any chances, and let Sing Core build your very own custom jib door.
