Dual Pocket Doors Made with Sing Core

People often think of doors as simple barriers or entryways, but at Sing Core, we know that a door can be much more than that. Doors can be elegant accents to a room’s design, or a seamless way to change a room’s layout. If done right, they can even be part of a room’s main design feature, such as in the example we’re showing you today.

This customer needed a way to separate two areas of the house, but was fairly limited in their options due to their design preference. Due to the height of the room, a standard door would not work unless they expanded on the center wall, which would majorly damage the flow and beauty of the room. A normal sliding door would work, but the dimensions would be incredibly difficult to get right. The door would have to be incredibly tall, yet narrow, which would need to be custom made. If this was done with traditional materials, the doors would likely be too heavy to work reliably, and could damage their hardware. Sing Core, however, was a great solution.

Because Sing Core panels are made with a honeycomb core, they are incredibly lightweight, yet still very strong. This means that the custom doors would still be sturdy and long lasting, but due to their low weight, they’d also be easy to use and be far less likely to damage their hardware. In fact, each of these doors only weigh 200 pounds, despite being over 13 feet tall.

These twin pocket doors measure 40 inches wide by 158 inches tall, and are 2.5 inches thick. This tall and narrow design worked beautifully for the room, though is definitely a non-standard size. Getting a door like this without having it custom made would be impossible, but luckily Sing Core specializes in large, high end custom doors.

A Sing Core door can be ordered to nearly any shape or size, and are strong, lightweight, and durable. One major concern with large doors is the possibility of warping, which gets exponentially more likely, and often exponentially worse, with larger doors. In the case of this project, even just a slight warp could ruin the entire system. A little bend or twist could leave a door stuck in its pocket, or scraping the side as it is opened and closed, damaging both the door and the wall nearby. There are many ways a warp can hinder or ruin a door, and often, warps are irrecoverable. Sing Core doors are guaranteed to never warp, and we can make that claim due to our innovative and patented honeycomb core. In fact, each door panel comes with a 50 Year Warp-Free and Structural Guarantee, so you can rest easy without worrying about your door failing on you.

Sing Core is thrilled to have had the chance to work on this beautiful project, and we hope to work on your next amazing project with you. Submit a quote request on our website to learn what we can do for you!

Lounge Room Door Made With Sing Core

Sing Core has been working with several universities regarding custom doors lately, such as with the University of Idaho and their arena door, the University of Alabama and a sorority house door, and now the University of Maryland with a custom sliding door for one of their lounges.


The University of Maryland worked with the brilliant people at USAM to get a large custom sliding door for their Heritage Community lounge room, and they reached out to Sing Core to make that work. Sing Core and USAM worked together to create a beautiful 3 piece modular sliding door. This door can separate into three panels along the sliding track, allowing for a custom setup to the walkway. It can also be completely opened and closed in order to really open up the area.

This large sliding door measures 168 inches wide by 120 inches tall, and is 2 inches thick. It contained splines to stiffen the panels and further improve the structural integrity, as well as a Formica finishing panel to give it that gorgeous end result. The door parts slide along an upper rail, which provides smooth and reliable operation.

This lounge room is in Pyon-Chen hall, one of two areas that make up the Heritage Community at UMD. It is a multipurpose location, intended to suit all sorts of recreational and student needs. Due to the location, the unique modular aspect, and the traffic, the designers of this door needed to make sure they got a high quality, durable, and long lasting product. That is why they went with Sing Core, and we are honored that they did!

Sing Core panels have many benefits over traditional door making methods, but there are three main ones that relate to a project like this: strength and durability, weight, and lifespan.

Sing Core doors are incredibly strong and durable, though surprisingly lightweight. This is possible due to the patented honeycomb core used within every Sing Core door. This honeycomb core provides exceptional strength and impact resistance, while also remaining amazingly lightweight. Where a traditional door panel may take several people to haul and install, most Sing Core panels can be carried by only two people, and even one if the panel is sized right.

The patented core and high grade materials used also give our doors outstanding durability, preventing many of the damages that would otherwise leave a door ugly or unusable. Especially being in a high-traffic area such as a university lounge room, durability, impact resistance, and longevity are vital. Heavy traffic walkways can see increased damage to the doors and walls around them. Sing Core doors aren’t easily damaged, and if they do receive a ding or scratch, they are easy to repair. In addition, all Sing Core panels are guaranteed to be warp-free for 50 years, which is unheard of in the door market. Warped doors are a massive problem, and unfortunately, many doors can eventually warp, regardless of the care put into making them. Sing Core doors, however, are guaranteed to never warp, and that is all thanks to the unique construction used to make them.

Sing Core is thrilled to have had the chance to work on this amazing project. Thanks again to the University of Maryland and the talented design and installation teams, as this would not have been possible without them.

Hideaway Bar Made with Sing Core  

At Sing Core, we are always looking to highlight amazing and creative projects and uses for our door panels. This recent hideaway bar door does just that, and it looks incredible, too!

This customer wanted a door that could cleanly close and conceal the bar behind it, then upon opening have the doors slide and store inside the revealed room. This minimizes the footprint of the door system and allows for a much cleaner, less intrusive appearance and function. In order to make this work, our client needed a high quality, lightweight, and durable door panel, as something without these qualities simply wouldn’t work.

A lightweight panel was required, as anything heavy would ultimately wear down and break the hardware used to mount it. This is especially true in cases like this where precise and fine tuned hardware must be used to achieve the desired function. Heavy and unwieldy panels would greatly reduce the lifespan of these beautiful doors, which is one of the primary reasons this designer went with Sing Core.

When dealing with doors that have as unique of a function as these do, you need something you can rely on to last for a very long time. Repairs to door systems like this can be costly and difficult, sometimes requiring the complete replacement of various parts. That’s another major reason why a Sing Core panel was used for this project, as both the client company and the end user can remain confident with such a high quality product. Sing Core panels are guaranteed to remain warp-free and structurally sound for 50 years, so the customer doesn’t have to worry about a panel warping over time and ruining their door system.




The customizability of Sing Core panels is another great feature for unique projects such as this. The client had very specific requirements for their panels, which is reflected in the shop drawing to the right. This shop drawing shows the specifications for both of the panels used in this project. The panels needed to be exactly 33 inches wide, 112.5 inches tall, and 1.75 inches thick. These doors were made to professional grade quality and finished with MDF. Once sent to the client, they were able to provide the final details needed to turn these into the beautiful doors you see in these pictures.

While Sing Core is typically used for large custom doors, office sliding doors, and more, we still enjoy seeing the creative use of our panels’ versatility, such as in this project. If you have a project in which you need a custom, lightweight, and strong door or wall panel, don’t hesitate to visit our website and submit a quote request. We can’t wait to work with you!

Custom Sliding Door

The new and improved custom sliding door projects at Sing Core are always exciting as they specialize in solving the problems associated with large custom sliding doors for the most expensive homes in the world as well as custom & replacement doors for closets, media rooms, garages, bedrooms and offices.

While the biggest custom sliding door presents many problems to the contemporary architecture and design firm, using the finest large sliding door engineers, Sing Core reaches out offering solutions to any of the problems which may be faced when trying to create a visionary’s custom sliding door ideas to life.

If you are looking for a custom manufactured sliding door system, you would be well-served to seek out inventor Peter Sing’s patented and patent-pending custom sliding door systems and solutions, resulting in Eco-friendly lightweight and high strength custom sliding doors which are built to last for centuries but guaranteed for 50 years.

Sing’s True Flat Team at Sing Core rises to the task every day to take the headache out of realizing your custom sliding door vision, especially if you are struggling with a large sliding door opening, and wrestling with a building material which is difficult to keep straight, such as the case of natural wood sliding doors.

Natural wood presents the biggest problem for door manufacturers because wood moves, what we in the business call, “door warping.” There is little pride associated in building any custom sliding door that will warp months or weeks after installation, regardless of how beautiful it might be.

Enter Sing’s invention of Sing Core, the only way to build an Eco-friendly lightweight custom sliding door that is stronger than steel pound for pound (independently tested at 660+ PSI) and can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.

Sing has creating warp-free large custom sliding doors down to a science utilizing his inventions to build any door you want around his warp-free door core substrate which is engineered and manufactured to match your choice of any surface material to keep any custom sliding door of any size, even up to 40 ft. tall and/or wide or larger from warping, whether they are interior sliding doors or exterior sliding doors.

The most problematic large sliding doors are exterior sliding doors because one side faces the interior of the structure while the other side may be one hundred percent exposed to weather. This is the perfect recipe for warping doors, unless they have Sing’s patented core inside.

Which makes the Sing solution a perfect match for custom made patio doors which could be made of any available flat building material, which not only gives you a true flat, warp-free panel sliding patio door, but you get the added safety and security that comes from having insulated custom patio doors.

Sing’s custom sliding glass and hinged patio doors are the contemporary glass opening approach to having that French door design access connecting the structure’s interior with the outside whether doors are secured or wide open for the most modern sliding patio doors. This also makes the Sing solution the top resource for replacement sliding patio doors which may never need replacing again.

The fully embedded insulation in Sing’s hybrid design sports an R-value of 3.5 to 6.5 per inch in thickness, assuring you more safety, security, privacy, and climate control with fully customized sliding doors for your home that are beautiful, and energy efficient impact resistant doors.

Peter Sing works together with the contemporary architects and modern designers to create custom made sliding doors unique to the design, function, and high precision expectations while delivering the best dimensionally stable results possible with his new hybrid custom sliding door technology, available in nearly unlimited and extreme custom sizes.

So, if you’re looking for bringing your superior custom sliding door design to life, regardless of size and limitations of your most desired materials, Sing Core can help to bridge the gap between what was previously impossible and the birth of all your replacement and new oversized sliding doors.

To either create or re-create your indoor/outdoor living space with custom sliding doors, all you have to do is to contact the sliding door company of your choice and tell them what you want. Give them the specs of your dream door, including the height, width, and thickness, as well as what material you would like to have the door made of, and don’t forget to tell them you want, “Sing Core inside.”

No two sliding doors are the same as Sing’s 100% custom sliding doors are created with the love and care of fine handcraftsmanship in his factory nestled in the scenic Pacific Northwest in Washington State. Even though his location is somewhat remote, Sing Core ships every day to destinations across the United States and around the world.

The number one delivery location is the greater New York area. It’s a good thing that Sing’s Custom-made sliding door blanks are so lightweight, that shipping them across America is far less expensive than other materials of the same size.

The rest will result in all your architecturally beautiful interior sliding door and custom sliding door dreams coming true for you and your most discerning clientele, all backed by inventor Peter Sing’s 50-year warp-free guarantee.

Every door with Sing Core inside is custom-made in the USA and built to last centuries. See our new C Series line of Affordable Barn Door and Sliding Closet Doors.
