Why Millworks Choose Sing Core

Millworks, what’s the most important thing when choosing a Door?

A 50-year guarantee vs. a 1-year guarantee in the oversized Millworks and door manufacturing industry.

“If millworks are looking for a door with the best guarantee against warping, Sing Core stands out as a top option. They offer a remarkable 50-year non-warp guarantee on their doors. This is one of the best in the industry. This applies to a range of door types, including large, oversized pivot doors, sliding doors, and veneer doors.

Their patented Sing Core technology is used by high-end door manufacturers to create lightweight, high-strength doors that resist warping, bending, and twisting, even in challenging conditions. This guarantee is particularly important for large doors, which are more prone to warping due to their size.”

Most other door manufacturers typically offer a 1-year warranty, and in some cases, large doors may not have any warranty at all, since warping is a common issue in the industry. Therefore, Sing Core’s 50-year guarantee sets a very high standard for durability and performance.” Beauty is not skin deep. It’s what’s inside the door that counts.

How to get Sing Core. The process typically looks something, like this:

1. First, the Architect specifies, “SingCore” inside the product.

2. Second, the General Contractor seeks out a qualified Millwork who obtains unfinished pivot door from Sing Core.

3. Next, Sing Core manufactures the pivot door blank to architectural specs and ships to millwork.

4. Millwork finishes and installs hardware and provides finished pivot door to the job site.

5. Finally, installers hang and install the pivot door.

Get Things Done Right the First Time

Millworks and door manufactures are rightfully wary about building and installing large or oversize wooden doors. That’s why the top millworks in the country choose SingCore for challenging projects where they need to get things right the first time.

Why Door Millworks choose Sing Core

First, our focus is on high-end jobs. Indeed, we want to work with high-end luxury door millworkers. Specifically, Door Millworkers are necessary for our doors. In fact, we don’t make one-size-fits-all doors. As a result, our doors aren’t mass-produced. Indeed, Sing Core only builds custom doors. All in all, we focus on large and oversized doors. Certainly, doors that require being lightweight. In particular, we provide the door millwork with our door panels.

In summary, we supply door panels that are lightweight, insulated, sound-deadening, and can be built to any size. Of course, we let the door millwork handle the finishing. Thus, we don’t deal with finishing, hardware, or prehanging. In particular, we believe in the link of production. Specifically, for high-end luxury homes, everyone has a role to play. 

In summary, Sing Core isn’t like other door suppliers or manufacturers. Indeed, we build impressive entrance doors and interior doors. As a result, our custom designs are unique to fit your project. When we’re specked by architects, we always recommend they use a good door millwork. Certainly, Sing Core doesn’t go to the job site.

In conclusion, your skill is critical in building the best door. Above all, with Sing Core’s patented and patent-pending technology, we’ll reach the highest expectations. Next, check out our gallery to see how we can provide the substrate door for your next project.

How You Know Sing Core’s the Best Door Panel Manufacturer

Sing Core is unique because it’s 90% foam and 10% natural renewable vertical grain wood fiber. In combination with its honeycomb structural design, Sing Core creates the strongest, lightweight, dimensionally stable door. These doors have the highest structural strength, insulation, and sound-deadening properties. 

If you kick a door with only foam, the door might collapse or delaminate the skin. The whole structure could fail. That’s why other lightweight doors don’t offer a 50-year guarantee. This Sing Core difference is critical because moisture changes make the wood susceptible to swelling.

When you have a large door, it’s incredibly sensitive to expansion. That’s why traditional wood-core doors typically come with only a one-year guarantee. The more wood, the less stable. Sing Core being mostly foam eliminates that problem and still provides exceptional strength while remaining lightweight. 

 

 

Why Sing Core is the best: It’s a honeycomb urethane core. Sing Core rises ahead of the competition compared to other cores. Aluminum core for instance is strong. However, many aluminum cores are paper-thin and lack the density needed for true structural support. Without the thickness of Sing Core, the core has a tendency not to bond well thanks to stretching and a lower thickness.

If you increase the density, you create a structure that’s too heavy for large custom doors. Aluminum also doesn’t provide high levels of insulation and doesn’t deaden sound. Sing Core, however, offers the perfect balance of strength and lightweight composition with a dimensionally stable structure that also meets insulation and sound-deaning needs. 

Other lightweight cores, like paper, cardboard, particleboard, LVL, or regular wood-based cores, can’t compete against Sing Core. They tend to warp over time, soaking up moisture and often leave your clients disappointed. Most of these doors only come with a one to five-year warranty. But with Sing Core’s technology, you get a core that doesn’t warp and comes with a 50-year warp-free guarantee. For a high-precision door, it’s what’s within the core that matters.

How Sing Core supports contemporary architecture and brings original architectural doors to life.




Why Specify Sing Core?


The primary reason top architectural firms specify Sing Core in their specs is for large doors because every door over three-and-a-half ft. wide or seven ft. tall is going to have a problem with warping, and Sing Core is the only way to build an Eco-friendly lightweight high strength fully insulated door which can be


Guaranteed Warp-free for 50 Years


This sets the bar extremely high, and when architects want to deliver the best for their particular high-end clientele, as specifying “Sing Core inside” elevates the project to an entirely new level.


Renowned for non-warping large doors, SingCore’s patented and patent-pending building materials can do so much more. Next up on the list of reasons why architects seek Sing’s materials out for their upcoming projects includes lightweight dimensional stability and unsupported spans.


 


Here, Sing stands amidst a 13 ft. one-inch thick panel between two sawhorses, and you know if he were standing on any other building material, he would be standing on the ground. Yet, there he is suspended with little or no deflection. It boggles the mind, the possibilities of Sing’s core.


 


And Sing’s factory, located in the pristine forest region of the Pacific Northwest builds more than panels. He also builds posts and beams for use in other types of construction applications, which are just as lightweight and strong, if not stronger.


How Strong is Sing’s Core?


Independently tested, Sing’s core is 660 PSI, many times stronger when compared to any other lightweight honeycomb-type building material which usually clocks in at between 10 and 110 PSI.


While lightweight and fully insulated, Sing Core is stronger that steel pound for pound.


 


Architectural Lamination


When it comes to architectural designs using high precision lamination, Sing’s factory and his high precision laminating specialists provide top of the line results with unparalleled visual impact.




Laminates can be mixed and matched in any specified pattern, orientation, or specific shapes. In fact, Sing’s stile and rail surface lamination makes his high-end door blanks look like a high precision stile and rail door, for which he is well known for in the industry.


SingCore’s lamination is also included in his no-fail 50-year guarantee.


Any Surface Material


Due to Sing’s True Flat Team’s ability to keep any surface material straight and true, you will find them constantly hard at work designing the warp-free components to keep solid wood stave straight and true for 50 years, though their expertise is not limited to unstable wood grains.




 


Nearly any available flat building material can be incorporated with Sing’s core, including exotic natural wood grains, aluminum, brass, brick, bronze, cement, cold rolled steel, concrete, diamond plate steel, fiberglass, Formica, FRP, galvanized steel, hot rolled steel, HPL, Kevlar, Masonite, or stainless steel, just to name a few. That should get your creative juices flowing.




But there’s more


Any Size


Due to the incredible light weight of Sing Core and super strong resilience, the largest doors in the tallest buildings in the United States are built with Sing Core inside. 


 


us-navy-singcoreThe last thing you want on the top floor of the World Trade Center, is a warped door, and that’s why you’ll find Sing Core inside those doors.


You could find Sing Core from beneath the depths of the sea (US Navy) to outer space (NASA) and everywhere in between.


Any Application


There’s no doubt you will find Sing Core inside the finest oversized large doors, but you may find Sing’s core inside any item that is lighter in weight but expected to be used over and over again over a long life span.


100-YEAR FURNITURE


You will find Sing Core inside 100-year furniture (that’s furniture that is designed and built to last for a hundred years). This is in stark contrast to more popular inexpensive import furniture which is expected to be basically disposable.


You will discover new and varied ways to use Sing’s patented and patent-pending technologies for signage, floors, walls, ceilings, emergency shelters, modular work sheds, tiny houses, museum displays, store fixtures, and modular trade show booths which are designed to be knocked down and rebuilt over and over again for years on end.


A variety of travel industries are benefited by using Sing’s technologies, including, but not limited to hospitality, aircraft, aerospace, marine, rail, trucks, trailers, and RVs. 


 


Even entire homes have built of Sing’s patented Sing Core.

Sliding Doors NYC
   

			

					

				
Welcome to the biggest and best sliding doors NYC ever heard of! The inventor and president of Sing Core hails from New York City and so it’s no surprise that most of the sliding doors in New York that have his patented and patent-pending lightweight high-strength warp-free core inside can be found in the Big Apple.




Even though Peter Sing and his factories are located among the pristine forests of the Pacific Northwest in Washington State, the majority (53 percent) of his warp-free door cores ship to New York, NY 10001, while the rest could ship to anywhere around the USA, or the world.

What makes Sing’s the most desirable sliding doors NYC craves?


Sing’s inventions allow the biggest and best door manufacturers, high-end millworks, and custom door builders in New York to build large oversized sliding doors which possess unique characteristics which cannot be found by any other sliding door manufacturing method.


Safety, Security, Privacy


If you live in New York, you may have noticed that New Yorkers value their safety, security, and privacy, so it helps to have a sliding door that is strong enough to be a deterrent to any unwelcomed breach, and insulated enough to keep your goings on from spilling over to the next room.




Stronger Than Steel, Soundproof


Sing’s patented sliding door core has been independently rated at 660 PSI, that’s stronger than steel pound for pound, and is fully insulated for both soundproofing and climate control. These are the primary characteristics you might desire in a high-end impact resistant door in The City That Never Sleeps.


But that’s not all.


Lightweight


Eco-friendly Doors with Sing Core inside are also lightweight, one-third or less the weight of any other conventional wood-based solid core door. This light weight offers many advantages, including but not limited to, less expensive to ship, easier to maneuver, handle on the job site, and install.


Save on Hardware and Maintenance


You save a great deal on hardware because the hardware is based on the weight of the sliding doors in NYC. The heavier the door, the heavier duty (and more expensive) the heavy-duty hardware will be. Also, all that heavy weight puts added stress and strain on the hardware and the structure, causing the need for regular maintenance on the NYC sliding door over time.




You don’t have to worry about all that ongoing maintenance because doors made with Sing’s core inside are covered by Sing’s


50-year Warp-free Guarantee


That’s no typo. That the truth. Sing’s doors come backed with a 50-year no fail guarantee, which means your door will not warp, bend, twist, or otherwise fail (including delamination and full structure warranty) for 50 years!


That’s why Sing’s best clients admit,


“There’s just no other way to do it.”


No other door can do what Peter Sing’s doors can do.


And there’s more…


Any Type of Door


Architects love specifying Sing Core doors because Sing empowers door manufacturers, millworks, and custom door manufacturers to create doors out of any available flat building materials, including any natural wood grain species, aluminum, brick, brass, bronze, cement, concrete, cold rolled steel, fiberglass, FRP, galvanized steel, glass, hot rolled steel, HPL, laminates, or stainless steel, just to name a few.


And your super strong lightweight impact door can have the appearance of any style of door you can imagine. Just check in with Sing’s True Flat Team to see how to have your existing doors re-engineered to look like your old doors, but perform like Sing’s new doors, as has been done in historical restoration products using Sing’s patented building materials.




Any Size of Door


If you have a big door opening, not problem. Sing’s sliding door in New York, NY can reach heights and span openings up to 50 feet or more, no problem.


All backed by Sing’s 50-year warp-free guarantee.


That’s why you can find doors with Sing Core inside anywhere from beneath the sea (US Navy) to outer space (NASA) and everywhere in between, when it makes a difference to you or your family to have The Best Doors in New York.


Don’t believe me, visit Sing Core dot com and check it out for yourself, and say, “Hi,” to Peter Sing, a fellow New Yorker, who is working hard for you and to make New York a better place from 3,000 miles away every day.

Looking for a door drawing? Look no more because we’re providing you with a free door sketch online just by visiting this page. On that page you can enter your doors specifications and see an immediate 3D rendition of your door rotating on screen. If you like the 3D preview of your door, you can then click on VIEW SHOPS to view, save, or share your door drawing.




This functionality is embedded in Sing Core’s pricing page, but you do not have to submit a price quote to access the power of this user-friendly simple door drawing software.


This is how you can make your door drawing easy as entering your door’s measurements, height, width, and thickness, then selecting a door skin. The resulting is a complete door drawing with dimensions, which will help greatly in you’re getting the door that you want, even if it doesn’t have Sing Core inside.


We understand that not all doors need to have Sing Core inside, unless they are over 7 ft. tall and/or 3 ½ ft. wide, but still, the owner/inventor Peter Sing wants to share his software with you, nearly as much as he’d like to see his patented and patent-pending Eco-friendly lightweight, high strength, and fully insulated building material inside every home.


He hopes you’re able to use his online simple door drawings, which admittedly aren’t the fancy door drawing you might receive for your high-end custom door, but the intention is to make it easier for you to get your free door shop drawings, which are far better than just a simple door sketch.


Sing’s specialty is large doors. He provides his patented and patent-pending large door building technologies to the biggest and best door manufacturers, millworks, and custom door builders, enabling them to build enormous doors, up to 50 ft. or more, that are lightweight, high strength, and can be guaranteed to remain warp-free for 50 years.




Building most any kind of large oversized Eco-friendly lightweight high strength door that doesn’t warp is virtually impossible, unless it has Sing Core inside.




Note that the free door drawings will each represent a flush door drawing which may include a wooden door section detail, or may host other exterior surfaces, such as, aluminum, cold rolled steel, fiberglass, FRP, galvanized steel, hot rolled steel, HPL, or stainless steel, just to name a few.




If you will need glass window lite openings included in your drawing, you will have to annotate those by hand, as this feature is currently unavailable wit your free door drawing.


In this manner you don’t have to worry about how to draw the door as you can use the Sing Core method to provide you with a drawing of a door       which you can then modify to meet your door’s specifications.

Architectural Flush Wood Door
   

			

					

				
Working hand in hand with architects, door engineers, designers, millwork shops, and custom door manufacturers is everyday life at SingCore, nestled in the Pacific Northwest. This is where architectural flush wood doors move from idea to reality.


Yes, architecturally inspired flush doors can be purchased off the shelf. But an authentic architectural flush wood door is something entirely different. It is purpose-designed, custom-engineered, and created for a specific place. It carries intent, proportion, and material choices that cannot be replicated by standard production doors.


An architectural flush wood door may be one of a kind, or it may be part of a larger vision requiring hundreds of perfectly matched doors. Either way, each door is made for its environment, tied directly to the architecture it serves, and unmistakably specific to that project.


Architectural doors are functional art. Much like artwork on a wall, reproductions exist, but they lack the depth, precision, and presence of an original. To a trained eye, the difference is immediate.


Some clients simply won’t accept anything less than the original.




Architectural flush wood doors are comprised of many materials combined in unique ways to create a unique door that is unlike any other. An architectural door designer might mix different wood grains in a unique design pattern on the flush door’s surface to create such an individual work of art.


The architectural door artist may also combine different materials into the door’s design, such as, wood, metal, and glass. Other materials, such as aluminum, brick, cement, copper, fiberglass, hot rolled steel, laminates of all varieties, plastics, and stainless steel, just to name a few of the most popular.


The best architectural flush wood door is a composite of many materials, and nobody know the intricacies of precision bonding many different materials together, all working in unison of the whole, all the (and here’s the kicker) while,


Remaining Perfectly Straight for 50 Years


than inventor, Peter Sing, who provides his patented and patent-pending architectural flush wood door technologies which are revolutionizing the way architectural doors are made.


The biggest and best architectural wood doors are large oversized flush architectural grade commercial doors, that can be very large, up to 50 ft tall or wide. (That’s a big door.) As you may have guessed, especially if you have some experience with any doors which are oversized, that keeping it straight is going to be a problem.




 


Any large door, over 7 ft tall or three-and-a-half ft wide, is going to present a problem with moving over time and the problems are exponentially worse if you’re dealing with a natural wood grain door. Due to the nature of natural wood, it expands and contracts in accordance with changes in the environment which results in the door warping, bending, twisting, or cupping.


Left to its own devices, such a large door will be problematic for the end user, requiring regular maintenance to deal with its propensity to move. That is, unless it has


Sing Core Inside


Patented Sing Core enables all the greatest door companies in the world to build enormous doors which will remain warp-free, even if they are constructed of natural wood species.


10×12 ft 3″ thick warp-free 1/8″ oak 520 lbs


Of course, contemporary architecture and modern designers have resorted to using non-natural faux wood grain materials such as HPL to prevent the warping of architectural flush wood doors, but even so, those incredibly large doors still presented a problem with staying straight.


SingCore’s patented and patent-pending warp-free door solutions along with the years of technical expertise of his True Flat Team, can help create high precisions architectural doors results unsurpassed by any previously available door-building technologies.


These new leading-edge door manufacturing processes and anti-warp materials are able to produce doors of any size, made of any flat building material (yes, even natural woods) which can be covered by Sing’s unprecedented,


50-year Warp-free Guarantee


All SingCore’s premium flush wood doors are covered by a 50-year guarantee which covers any movement, as doors made with these technologies with not warp, bend, twist, cup, or otherwise fail (including structure and delamination) for 50 years.


No other company can offer such a guarantee on an Eco-friendly, lightweight, high-strength wooden flush door.




Added Architectural Benefits


Besides being warp-free and having the best and most long-lasting guarantee in the world, architectural doors that have sing Core inside also have many other extraordinary characteristics, such as


1. Lightweight


Architectural doors made with Sing Core inside are 1/3 the weight of other solid core doors manufactured with wood-based door cores. Creating doors so light in weight is extremely advantageous in reducing transportation and installation costs, as well as reducing the expense of heavy-duty architectural door hardware which is based on the weight of the door. A lighter weight door also translates to reduced maintenance costs related to regular door operation which if the door is heavier will increase stress and strain on both the structure and its hardware over time.


2. High Strength


No other Eco-friendly, lightweight door is stronger than an architectural door with Sing Core inside as these are the only doors which are stronger than steel pound for pound, independently architecturally rated by University at 660+PSI (many times stronger than commercial honeycombs used in aerospace at 10 to 110 PSI), making them the most sustainable doors known to man on planet Earth.


3. Fully Insulated


Even if your primary interest is having an architectural wood door that is straight and true, you might be pleasantly surprised that these are fully insulated for climate control (R 3.5 – R 6.5, or more, depending on architectural specs) and sport impressive sound deadening capabilities. It is not uncommon to find Sing Core inside the best soundproof doors in the most exclusive locations around the world in sound-controlled environments.


4. Solid


 


You should think about specifying Sing Core inside all your important architectural door projects.

Large Pocket Doors
   

			

					

				
For years, large pocket doors were not being installed in new builds due to problems associated with pocket doors which exceeded the normal range of door sizes. The biggest concern with these big pocket doors was their tendency to twist or cup according to the season.


If you haven’t experienced such challenges, it doesn’t take too much stretch of one’s imagination to entertain how frustrating it would be to open or close your large pocket door only to find it had seized up either inside or outside of its pocket housing.


Pocket doors are a magnificent way to cordon off an area or open up two adjoining spaces quickly and easily, and if your sliding pocket doors operate as expected, it’s an elegant sight to behold as the sliding doors smoothly disappear into their wall cavities. This is why they are sometimes referred to as a hidden pocket door or concealed sliding door. No swinging into the room so as to disrupt the area or require clearance for opening and closing, and not to be seen in the open position, as if they were never there in the first place.


Large pocket doors are coming back into new builds and remodels because he has provided the door industry with the warp-free technology required to create warp-free large pocket doors which can be guaranteed not to warp, bend, twist, cup, or otherwise fail, for 50 years.


 


Large Sliding Door Strong Straight Warp Free


Sing Core enables pocket door manufacturers to create large pocket doors of immense size built of any material, measuring up to 50 ft or more, and still be guaranteed to offer fail-free service for 50 years.


Sing Core’s eco-friendly patented and patent-pending warp-free technologies enable his factory to create non-warping substrates which are high precision (+/- .006 in.), fully insulated (R3.5 or R6.5) for sound dampening and climate control, lightweight (1/3 or less the weight of other wood-based solid core large pocket door blanks), high strength (660+ PSI, stronger than steel pound for pound), and backed by an unprecedented 50-year guarantee.


All that reduction in weight and increased strength, precision, and insulation changes the whole dynamics of a sliding door inside wall which would otherwise be problematic, so you don’t have to worry about your pocket sliding door that goes into a wall which may never come out. You can rest assured that your sliding doors into wall cavity will serve your safely, securely, and reliably over their 50-year guaranteed service life.


If you really want to upgrade your efficiency and the impact garnered by operating your precision large pocket doors, install a double pocket door. That’s right, two separate large double sliding pocket doors side by side, each sliding doors into wall cavity respectively independently or in unison. Make them full floor to ceiling large dual pocket doors for full effect.


Joining Large Sliding Pocket and Pivot Doors-Animated


Using this technology, you won’t have to worry about shelling out the big bucks for heavy duty large pocket door hardware because the hardware rating required to operate your door efficiently is based on the weight of your pocket door. Large pocket doors with Sing’s core inside weigh far less, enabling designers and installer to use less expensive pocket door hardware reducing the overall pocket door price.


Heavy duty pocket door track is unnecessary, as are expensive pocket door rollers, or other heavy-duty hardware or equipment. Sing Core’s lighter in weight large pocket doors are much easier to transport, manhandle, move about the job site, and install resulting in savings in pocket door cost all the way around.


Now you can have a heavy-duty impact resistant large pocket door that is lightweight and high strength without all the added expense and regular maintenance of any other type of heavy duty pocket door.

Pivot Entry Door
   

			

					

				
When it comes to large entrance doors, one pivot entry door comes to mind: That beautifully big pivot entry door with natural wood grain is so pleasing to the eye.




Q: How in the world do they keep such an enormous exterior wood door from warping?

A: With Sing Core inside.




Large entrance doors instantly garner attention and add curb appeal to any project, but featuring pivot doors as your entrance door makes an even greater impact on anyone who encounters such an enormous work of art.




Pivoting doors are more in demand because they attract attention like a magnet, especially if your pivot entry door is made of natural wood grain, because this just cries out: “Constant maintenance required” due to changes in the environment which causes such a big wood pivot door to warp. It doesn’t make the pivot door any less beautiful, but the regular maintenance can make such a door far less affordable over time.


That’s where patented Sing Core and inventor Peter Sing’s patent-pending anti-warp devices come to save the day. Sing, also the president of Sing Core, uses his latest technological advancements to help any pivot door company, millwork, or custom pivot door manufacturer build pivot entry doors of immense size quickly and easily without threat of failure or warping.




The idea of a new generation of warp-free modern entry doors is foreign to pivot door designers and engineers of yesteryear, that is, unless they have already heard about – and use – Sing Core inside their most important pivot entry door jobs.


How to Build a Warp-free Pivot Entry Door


Solid wood entry doors present the greatest numbers of challenges for the craftspeople tasked with transferring the architectural pivot door dreams into reality. We love the natural wood grain but it’s tendency to move at the slightest change in the environment creates problems. So, starting with Sing Core is the perfect place to start if you want to put your worries associated with exterior pivot doors behind you.




For years, Sing has been supporting the best of the best in contemporary architecture and designs, as well as the biggest most powerful pivot door companies in the world with the solutions to the problems associated with pivot entry doors over seven ft tall and three-and-a-half ft wide. Once you know how Sing’s core works, you, too, will know how to build a warp-free pivot entry door.


If you look deep inside the structure of Sing’s warp-free pivoting doors, you will find that the first component is torsion box, only the grain is oriented vertically instead of horizontally as is the case for traditional torsion box. Sing also keeps the structure grids of the torsion box very small, like two to three inches. Then, he fills the voids (the open centers of the individual torsion boxes which is normally left hollow) with recycled rigid foam.


Using formaldehyde-free adhesive, Sing cold-presses the composite materials together, sandwiched between two stress skins to create the solid hybrid warp-free pivot entry door blanks which are found inside the best high-end doors.


Even so, Sing’s warp-free technologies do not end there. Pivot entry doors are especially challenging due to potentially having one side of the door facing the elements, as in the case of exterior pivot doors, while the other side faces the structure’s interior. This is the perfect recipe for warping pivot doors.


Sing has a True Flat Team of door engineers in-house who assist in the design and creation of the core in such a way so as to account for all the challenges each pivot entry door may face. For instance, solid wood entry doors present the most problems, but not for Sing’s team.

Eco-friendly fully insulated (R3.5 to R6.5), lightweight (1/3 or less the weight of other solid wood-based cores), high strength (660+ PSI, stronger than steel pound for pound), impact resistant, climate control, and sound deadening pivot door substrate.
