Sing Core is honored to be a part of creating an intimate space inside restaurant Osteria Mornini in Miami, FL.
Nusla Design helped imagine this space and spearheaded the design. Following Nusla’s design, Sing Core fabricated four stunning door panels to be used in the Osteria Morini restaurant.
Watch the video below and hear the difference Sing Core’s true flat doors make.
These Sing Core sliding doors are used as a temporary room partition for private parties or meetings.
Sing Core doors naturally dampen the noise of the bustling restaurant. These doors were designed without the addition of acoustic skin layers or acoustic seals. Miami crowds can be lively, and this sliding door room divider creates a separate space to break up that sound transference.
The doors stack up flat parallel against one wall when not in use. Then each of three doors slides independently to the far wall to line up in a perpendicular position. And finally, the fourth door is a fixed pivot door that can swing in or out to completely close off the space. When completely closed the sliding doors and pivot door create a completely flat wall that is camouflaged to blend into the background of the restaurant. And with the use of the pivot door can still be used to serve the guests in a private setting while maintaining the look of a flat wall.
Notice how flat and straight Sing Core’s sliding doors are, even after two years of heavy use in a commercial space. Sing Core doors are created specifically to remain flat for 50 years using our patented and patent pending door technology.
These look like one single panel, but are actually to perfectly straight flush panels next to each other
This sliding door and temporary wall system was made using four Sing Core professional door panels. The panels are each 38.875” wide by 108” tall and only 1.75” thick. Each door was hot pressed with .020 vertical grain oak veneer. A professional millwork then received the true flat door slabs and stained the veneer to match the various other wood details throughout the restaurant and installed the sliding door hardware. Sing Core is able to provide solid wood blocking in our customers’ specified locations to suit their hardware requirements. As in this case where no blocking is needed for door pulls to keep the illusion of a flat wall when in use.
Each panel can be slid on the track with only one finger. Sing Core’s lightweight door technology keeps the weight of each panel down to less than 150lbs.
Sing Core is proud to be a part of the continued evolution of door technology to make our customers’ lives more enjoyable. Whether that be in pivot doors, sliding doors, hinge doors, pocket doors, or any oversize door. We enjoy the challenge. We invite you to GET AN ESTIMATE and see for yourself how Sing Core’s true flat door cores can help you make the doors that your customers are asking for. Here’s to a Happy holiday for you and yours from the entire Sing Core family.
It was a pleasure to visit this breathtaking restaurant in Miami Beach, FL. And we encourage you to have a meal at this New York Times voted best Italian restaurant in Miami, FL.

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.
Sing Core is on the leading edge of building very large doors, and in the process we are getting better and better which means our doors are becoming stronger, lighter, and even more dimensionally stable than ever before.
We have applied several new patent-pending technologies to further yet improve our doors.
Take a look!
Why are we always the best?
Because the SingCore team is always creating new ideas which are then put in motion to produce the best door in the world. Our innovation never sleeps and is constantly evolving to overcome any challenges our products may face.
Our specialty is very large doors; such as oversized pivot doors, sliding doors, hinge doors or even garage doors. Our patented and patent-pending technologies are applied to much more than our doors. Some other popular applications include room partitions, tradeshow displays, tiny houses, and much more.
This picture,
will show, it may look no different than other doors. But this is the highest precision. Strongest lightweight, large door in the world by applying several of our new patent-pending technologies.
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.
Sing Core’s alternative to aluminum honeycomb panel. aluminum honeycomb panel is used as core material in a variety of applications such as facades, walls, floors, ceilings, roofs, inside doors and partitions. Aluminum honeycomb core also found inside workbenches, craft tables, laser cutting tables, and a wide range of other types of work surfaces, especially when there is a desire to reduce the weight of the end product.
Increasingly, Sing Core is replacing aluminum honeycomb core with its Sing HPL Sandwich Core.
Sing HPL Sandwich Core
Sing HPL Sandwich Core is far superior to any aluminum honeycomb core in the following areas:
1. Strength-to-weight ratio
2. Fully insulated
3 High precision
4. Longevity
5. Eco-friendly
6. Warp-free
7. Low cost
Sing HPL Sandwich Core serves as base core in many industries including government, scientific, universities, military, space exploration, aeronautics, nautical, in submarines, public transportation, railways, corporate, and industrial warehousing, just to name a few.
1. Strength to Weight Ratio
Sing HPL Sandwich Core exceeds all expectations when it comes to strength vs. weight thanks to SingCore’s patented and patent-pending technologies which are the foundation for the success of Sing’s core. Long ago, Sing coined the phrase,
“Heavy does not mean strong, and lightweight doesn’t have to be weak.”
Sing’s invention changed the way architects and engineers brought their creative endeavors and problem-solving solutions to life.
2. Fully Insulated
Sing HPL Sandwich Core is a key ingredient in breach proof impact doors, and other applications where sound proofing, refrigeration, defense, and separation is imperative. Due to the nature and construction of Sing’s HPL Sandwich Core, no effort needs to be made to achieve an acceptable degree of sound deadening or climate control.
3. High precision
When the attention to detail demands high precision, no core material is more precise or stable than Sing HPL Sandwich Core sporting an impressive .006-inch tolerance. This is why Sing HPL Sandwich Core is hands down the go-to solution for dead flat tables supplied by the best high-end millworks in America today.
4. Longevity
When it comes to composite cores, risk is assumed in the area of the lamination process which holds the various products together over time. Sing’s patented and patent pending technologies eliminate the risk of delamination over the life of the product in use. And even comes with a 50-year structure warranty which includes delamination, so you don’t have to worry about it.
5. Eco-friendly
Aluminum Honeycomb Panels are made offshore and imported for use in the USA. Why? Because the production process is so toxic to the environment that it would be nearly illegal to manufacture in the United States. Even so, we still share the same air and oceans with our neighbors outside our borders. This matters to Peter Sing who only uses USA-sourced and natural materials holding the highest standards for Eco-friendly manufacturing methods for a better world.
6. Warp-free
Sing HPL Sandwich Core is long-renowned as, “the only way” to create large, panelized structure materials that will not warp under strenuous conditions. Though note that Sing’s True Flat Team must be involved in the engineering and manufacturing of the project because many factors must be taken into consideration to create a warp-free product, such as size, skin type, location, and application. Still, the only 50-year warp-free guarantee in the industry, regardless of size.
Other Types of Core Materials
Sing HPL Sandwich Core is vastly in the process of becoming the replacement core of choice over other types of lightweight core materials such as paper honeycomb, and different kinds of urethane core, EPS core, wood-based core, such as particleboard, LVL, solid wood core, as well as aluminum honeycomb core to keep the working subject straight, flat, or lightweight over time without fail.
Sing MDF Composite
Going a step beyond the Sing HPL Sandwich Core, one of the most popular hybrid composite products in huge demand is Sing’s MDF Composite available in core or panelized with solid wood edges and implants. This has the embedded HPL for all the high performance results, plus it is topped with a super smooth 1/8” MDF for easy painting or lamination of nearly any material.
Sing Core MDF Composite
This is one very basic, less expensive option, but if you want to be straight, with concern of warping, or telegraphing, would require an upgrade with special skin underlayment beneath the MDF skin on top of Sing Core.
This creates a either a core material or full panel with stable material on both sides with MDF skin for paint grade or cold press purposes. More stable translates to less chance of telegraphing, and designed for high-end precision and smoothness. The price is a little bit over than that of standard MDF-only skin.
But, if you want to do hot press, then you must take advantage of our special hot press process. That means you can accommodate the increased high temperature and high pressure without worrying about any telegraphing. This is the most expensive method for the most demanding clients.
