As we hit the half way mark of the 2022/2023 winter season, many are finding that their homes lack proper insulation in many different ways. One of the main reasons your home may not be holding warmth is your exterior doors. Doors are often poorly insulated, if even insulated at all. A poorly insulated door can surge your heating bill up, as it allows warm air to leave the home and cold air to filter in unrestricted. A door made with Sing Core’s patented honeycomb panels is guaranteed to improve your internal climate, as they are well insulated, lightweight, and can be made to fit any door size.
Why Choose Sing Core?
Sing Core doors offer many advantages over the standard options, and are the industry best in making high quality, durable, and lightweight doors. Our products are made with a laminated honeycomb core, allowing you to choose nearly any door design while still maintaining that high end Sing Core result.
In addition, our doors are guaranteed to be warp free. Doors can warp slowly over time, especially in areas with constantly changing weather. Rain, snow, freezing temperatures, and many other factors can lead to your door warping, and even the smallest warp can change the entire feel of your door. Sing Core doors are guaranteed to not warp, meaning you’ll always have a smooth and straight entrance.
We also offer a 50 Year Guarantee on our products, promising to stay sturdy and straight through that entire time. This brings you peace of mind to know that you will always be satisfied with your door, as it will stand the test of time regardless of the conditions.
What Are The Benefits of Sing Core?
In addition to the high end insulation and 50 year guarantee, our doors are also incredibly sturdy and lightweight. A typical door can be one or the other, but at Sing Core, we make door panels that are durable, without weighing down the hinges and being difficult to move. Because of this, we can make doors of nearly any size, further broadening your options with elegant tall doors, large garage doors, and many others. Our panels are also sound deadening, offering additional uses as interior doors for studios, or even exterior doors in loud areas.
What Kind of Doors Can Sing Core Make?
Nearly any door is an option when using Sing Core. Exterior doors, interior doors, large doors, pivot doors, sliding doors, and garage doors, among many others, all become a possibility with our amazing product. Plus, these various applications will all have the same benefits, so you can have an insulated garage door, a lightweight large door, and more.
We invite you to look at our customer gallery to see some of the amazing things we’ve been able to create, and when you’re in need of a high end door, remember Sing Core.

What are the benefits of a Sing Core door?
What other benefits come with Sing Core products? Well, for one, they’re lightweight. This means that the hardware and framing used to install the door don’t take the regular wear and tear that comes with other products that are significantly heavier. In addition, our doors are impact resistant and warp-free, meaning they won’t be ruined by bumping into them, and they’ll never warp on you. The fully insulated core offers increased control over your internal climate and gives you the assurance that you won’t be surging your heating bill up by installing one of our doors. They’re also sound deadening, allowing for use in many other applications where sound may be of concern. Lastly, our doors are crafted with high precision techniques by master craftsmen, guaranteeing a consistent and reliable product every time.
What doors can I use Sing Core for?

Interior view of extremely large pivot door with hardware
Case study:
A 55” wide x 19’ tall x 3.25” pivot door. With differing Cedar and oak wood stave skins.
Being approached by a client who is in need of a uniquely large pivot door to withstand the difficult climates of Lake Tahoe can seem like a near impossible feat. This pivot door needed to be lightweight for ease of installation and daily use by the client, impact resistant to hold up to everyday use, sound deadening to drown out the hustle and bustle of everything outside
A pivot door built with patented and patent-pending SingCore inside can make anything possible.
Exterior view of oversize pivot door with hardware
Opposing wood species
Dissimilar wood species on the interior and exterior of the door means differing rates of expansion and contraction. SingCore has the strength and stability to remain rigid against the push and pull of the dissimilar skins.
Lightweight oversize door
Lightweight
Now let’s take a look at why this door needs to be lightweight.
First off, big pivots doors tend to be very heavy which makes them more difficult to manage, they require custom made specialized hardware and require a lot of maintenance due to the stress that the pivot door adds to the structure.
Secondly a pivot door is only held with two points of contact on the top and bottom of the pivot door; meaning that if the door warps or twists, the door operation will be degraded or completely fail.
A pivot door this size with a solid core will weigh around 800lbs before any skins are added.
Now with SingCore, this door’s weight is a fraction of what other solid pivot doors would have weighed. This weight savings translates into a reduced overall budget by having lower shipping costs, lower hardware cost and lower cost for the labor of the installation.
Adverse climate for keeping oversize pivot doors straight
Ready for any climate
Lake Tahoe is known for its incredible skiing and breathtaking beauty. Not for its temperate climate.
This pivot door will see outside temperatures as low as 4°F while the inside temperature may be a toasty 76°F, which is a 72° difference.
SingCore pivot, sliding, hinge, and pocket door slabs are fully insulated with your choice of recycled EPS foam core (3.5 R value per inch) or urethane foam core (5.7 R value per inch).
Perfectly straight oversize pocket door
Straight
At 19’ tall this pivot door is as big of a challenge as it gets to keep straight.
All door slabs fabricated by SingCore are completely custom. The SingCore team takes into account the finishing, hardware, and climate when building each core. No two doors are alike. And we take great pains to ensure every pivot, sliding, pocket, and hinge door stays within AWI standards.
We love creating one of a kind oversize doors that no one else can.

Professor William Miller was a very kind and brilliant man. In his 88 years, he served as a radio decoder in China in WWII, received his PHD in Civil Engineering from WSU, taught at UW for 32 years as a professor of civil engineering. He was a great parent, scoutmaster, lecturer, and friend. In his spare time and in retirement he spent his time in his extensive wood and metal shop creating many treasures.
He made many friends and long-lasting relationships, including being a Scoutmaster for Bill Gates. But none were as special as his relationship with Peter Sing and his SingCore inventions. William provided excellent advice and was a great educator to Peter. William was shocked of the strength and lightweight qualities. After performing test on SingCore Beams, he was blown away at its shear strength and structure support with use of renewable fibers. Peter and him because very close family friends in the years to follow.
William was loved and is missed by all of his family, friends and previous students.

SingCore’s Legendary Curved Door has been called upon in the most demanding situations to turn even the most stale environment into a place where luxury and creativity flourishes. As a leader in manufacturing large, over-sized, sliding, pivot, metal, hinge, bi-fold, and man doors, SingCore has been at the forefront of our industry because of our ability to make doors that are stronger, straighter, lower in weight, more dimensionally stable, available in more materials, more warp resistant, and more visually appealing. Moreover, we offer the best guarantee in the industry. No one else in the industry can offer you doors that are guaranteed for 50 years against warping, twisting, breaking, cracking, and skewing. Because we have a proven track record of producing door that stand the test of time, we have decided to divert our attention to a new line of doors that are dramatically increasing in popularity. That is the SingCore Legendary Curved Door.
SingCore Unmatched Precision
These large curved doors have been made to the exact specifications of the client. No one can make a door radius as precise and versatile as ours. Most door companies are not even capable of producing a door that has a radius. With our cutting edge methods, we can build a door with any radius. Moreover, it will have the SingCore signature light weight core that allows us to build doors that are more structurally strong, more rigid, more dimensionally stable, less prone to skewing, breaking, and cracking under normal use. As you can see from our photos, they are much more beautiful than doors from any other curved door manufacturer. Our doors are solid as a rock. They go through our rigorous strength testing, including the hammer test.
Extraordinary Door Options
For better resistance to environmental conditions, we use marine ply skin on these curved doors.
Our panels are incredibly strong, plumb straight and ultra-lightweight. To meet the harsh needs of today’s ever-changing climate, SingCore equips you with a panel’s sub straight made of patented and patent pending core material. We can manufacture doors with countless diverse skin types due to our state-of-the-art methods and unique engineering. Sky’s the limit on what type of door skin you want as we built our doors to order with your specs. We manufacture the doors using any form of hanging arrangement, any skin, and any dimensions. Due to our innovative blocking system, you can install any hardware. Our revolutionary system allows you choice any kind of blocking you may need to complete your door. Due to every door being made to order, we are extremely flexible, just ask and we will make it happen.

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.
