If you want to find the best door in the world for you next project all you need to do is to use the best tool for finding the best doors, such as:
Google search pivot door
If you’re looking for the what constitutes the best doors, then you might search for the most expensive door. You will find that the door companies which can make the most expensive doors which outperform all other doors in terms of weight, strength, and longevity are the hardest to make. That is, unless you know the secret.
Best Door Secret
Pivot doors are problematic because they only have two points of contact whereby the pivot door is operated and anchored by the pivot door hinges.
Hinge doors can be secured by multiple hinges, even a full length piano hinge which anchors one whole side of the door completely. Even so, with one side fully anchored, a large door will warp, bend, twist or cup, causing it to fail. A warped door will compromise the door seal and may not be able to allow the door latch to secure properly.
High End Pivot Doors
Pivot doors rely only on those two pivot points, one on the top of the door, and the other opposite it on the bottom of the door. It is imperative for a functioning pivot door to remain straight and true, or else you cannot operate it properly.
Only the best pivot door companies can make a high-end pivot door which can perform over time without failing due to door warp.
50-year Warp-free Guarantee
All you have to do, is to contact the top pivot door manufacturers on your search results and ask them if they offer a large pivot door with a 50-year guarantee.
If they do, these doors will all have Sing Core inside.
With Sing Core inside your pivot door, it will be lightweight (a fraction the weight of other solid core pivot doors), and high-strength (at 660+ PSI, stronger than steel pound-for-pound).
9 ft wide warp -free weatherproof pivot door
You also have the added benefit of having a pivot door which is fully insulated for climate control and sound deadening capabilities (Sing Core can be found inside the most efficient soundproof doors in the world).
You Can Laugh or Cry
When you discover the secret of the most expensive high-end doors, you might start to laugh, but before you start laughing, think about this:
You might be crying, if you make the wrong decision, and find yourself in possession of a weak door which may fail prior to when you might have expected.
This is why most large door manufacturers will exclude large doors (over 7 ft tall and 3.5 ft wide) in the door schedule from the warranty following installation. Chances are they will start to fail at the next change of season.

Then you might reason (as many have) that if Sing Core can make the best doors in the world the most valuable doors in the world, then Sing Core could make anything better, and it does.
Doors and So Much More
Entire homes have been made of Sing Core, which is available in post and beam and panel formats, changing the way homes are built, including all the interior and furniture inside a Sing home.
Sing Core makes everything better and its Eco-friendly nature makes everything more sustainable over time.
Guaranteed for 50 years but built to last centuries

Insulated Walnut Door
Doors of Almost Any Style Could be Made with Sing Core Inside
1. Pivot Doors
Pivot doors are the highest and best use of Sing Core because for the most part, pivot doors are quite large in size and are often much thicker than a standard door. If your intention is to feature a real wood finish, you know you’re going to be in trouble, that’s when the warp-free attributes of patented Sing Core shines through as the only way to build a large wood door which can be guaranteed to offer warp-free performance over time: 50 years, guaranteed, on professional grade doors.
2. Sliding Doors / Pocket Doors
Sliding Doors often present problems when they are very large due to their sensitivity and tendency to move, bend, or cup in response to changes in the environment, for which Sing Core is the perfect solution.
Large bypass sliding doors are likely to deface, scar, or otherwise damage themselves if they are not kept straight and true by being built with Sing Core inside in advance of bypass door failure.
Pocket doors, which are the most problematic of all sliding doors, because they hide within a cavity are highly benefited from being built with Sing Core inside. If warped, the finish of the door may be compromised as it brushes against the frame or cavity’s interior, and if it cups or bends too far, may become lodged either inside or outside of the pocket unable to open and close as a door. Sing Core keeps them straight and true.
3. Hinged Doors
Hinged doors are for the most part manageable even when facing a certain degree of warp, which is normal in normal sized doors. Problems arise when doors are very large, especially if over 7 ft. tall or 3.5 ft. wide. Any movement or change in the door’s being compromised is increased exponentially in relation to the dimensions of the door. Not a problem with Sing Core’s professional door blanks.
Diverse types of hinged doors, such as French doors, sliding folding doors, front entry doors, and carriage doors (among other types of hinged doors), all present varying challenges when migrating from the drawing board to the real world, and Sing Core makes the difference.
While Eco-friendly insulated Sing door blanks could be used in doors of any size, the efficacy is maximized in door performance in any door over 7 ft. tall and 3.5 ft. wide. This is why you find Sing Core inside the largest doors in high-end homes, businesses, and industrial sites, because it’s the only way to build a large door which can remain straight and true, regardless of the size of the door, while still remaining lightweight.
Since every door slab manufactured by Sing Core is likened unto a one-of-a-kind piece of art, architects and designers are free to create a door of any size and shape using any available flat building material.
Sing door slabs can be created to accommodate any shaped design in any thickness, and so it goes for any shaped light cutout for glass openings.
Sing door slabs are available in almost any skin you want, limited only by flatness (surface material must be flat), ability to be laminated, and availability.
Some examples include, paint grade plywood, aluminum, brass, cement board, cold rolled steel, concrete, diamond plate steel, fiberglass, FRP, galvanized steel, glass, hot rolled steel, LVL, Masonite, stainless steel, any wood species including exotic species, and many more.
Our most common specialty includes the cold pressing of solid wood stave to our patented and patent pending core material, resulting in natural wood doors that can be guaranteed to remain warp-free for 50 years. Unheard of in the wood working industries. We also supply high end millworks with hot-press-ready warp-free substrates to apply their skins to.

It is well known among the high end pivot door industry that Sing Core pivot door blanks are the only way to create the best lightweight, high-strength pivot door of any size (even extremely large in size) that can be guaranteed not to warp, bend, twist or otherwise fail (including full structure warranty) for 50 years.
Breaking News FritsJurgens Pivot Door Hardware
It’s no wonder the clients who use patented Sing pivot door core to build their high end doors are using the latest in leading edge pivot door hardware. While your pivot doors for the elite may feature any type or style of pivot door hardware made by any of the most popular pivot door hinge manufacturers, one new type of pivot door hinge is getting installed in more large pivot doors with Sing Core inside.
It has come to our attention that the new System M hardware from FritsJurgens in Holland is what all the latest buzz is all about.
What’s the big deal?
The big deal around Sing Core is always about big pivot doors. Not only big pivot doors but the biggest pivot doors because you could be talking about thousands of pounds of a large pivot door, which could be reduced to ten percent of the weight by having Sing Core inside.
Architects, our custom door manufacturers and millwork clients rely on the lightweight fail-safe aspects of pivot doors made with Sing Core to keep your project, not only at the elitist level of excellence, but within a reasonable budget. While those huge pivot doors can be very expensive to build and handle, the sheer weight of the door dictates the hardware necessary to accommodate such a door.
Installation of the hardware to operate an enormous pivot door can require extensive engineering efforts as well as becoming a burden on the installation, especially if it is being retrofit into an existing structure (not so bad if prepared for in a new structure being built).
Then comes along Holland’s FritsJurgens with the perfect match of sleek System M hardware that is the easiest pivot door hardware to install, especially in a retrofit application, carrying a weight of up to an 1,100 pound pivot door. That could be a 37 foot tall pivot door with Sing Core inside!
Concealed Pivot Door Hardware
The pivot closer is concealed within the door, not the floor! Making this the easiest to install pivot door hardware, requiring very little modification at the job site to install. Some of our custom pivot door builders are able to transport a completed pivot door system fully installed and pre-hung from their factory or millwork to the job site for the easiest installation of pivot doors ever, thanks to FritsJurgens’ System M nearly concealed hardware.
If you’re using a Sing pivot door blank for your pivot door substrate and you plan on using FritsJurgens’ System M pivot door hardware, all you have to do is let our design staff know when you’re placing your order. Sing Core can pre-install the required blocking necessary to accommodate the FritsJurgens System M pivot door hardware.
If you’re upgrading an existing non-Sing pivot door to a pivot door with Sing Core inside, you will be glad to know that FritsJurgens’ new System M closer works with existing FritsJurgens top plate and top pivot.
At present, this is a leading-edge well-kept secret among the most elite high end custom door manufacturers, but we thought you would like advance notice before this product becomes more widespread in use across the United States.

Sing Core is providing the solution to the best pivot door companies for most of the problems associated with the large pivot entry doors.
Helping your favorite pivot door company create warp free wooden pivot doors of any size ~ guaranteed
Pivot Entry Doors | Warp and Structure
First of all, most of the most impressive architectural pivot entry door features natural wood. It doesn’t take much effort to imagine what the problems might be for a natural substance, like wood. The very nature of the grain, which add to the elegance and beauty of any pivot entry door, is the problem, especially for exterior pivot doors. While natural wood grain is so very attractive, it is natural and tends to warp, bend and twist due to changes in the environment. Even if the exterior pivot door is not made of wood, the structural integrity may fail, especially if the door is over 8 ft. tall and/or 4 ft. wide.
Pivot Entry Doors | Weight and Pivot Door Hardware
Secondly, a large pivot entry door is going to be very heavy in weight, which is expected with any door of significant height, width and thickness. Current trends to an increase of pivot entry door sizes pushes the physical limits of the capabilities of any standard pivot door company or their ability to accommodate pivot door sizes that are over 8 ft. tall. Additionally, the weight of these large pivot doors determine the type, style, and size of the accommodating pivot door hardware required. Heavy duty pivot door hardware appropriately matched can cost many times the cost of the pivot entry door, just for the pivot door hinges. Heavy large pivot entry doors also are problematic to ship to and handle at the job site, adding extra charges to installation costs.
Pivot Entry Doors | Ongoing Maintenance Costs
With the continued use of heavier large entry pivot doors over time, the regular articulation of the pivoting door causes extra stress and strain on the pivot door hardware, frame and structure as it is used. In addition to regular maintenance of the exterior pivot door’s tendency to move (warp, bend, twist or cup) other maintenance costs include repairing and/or replacement of pivot door hardware, framing and the building’s structure.
Pivot Entry Doors | Replacement Doors
Sooner or later, the owner or manager is faced with the task of locating a replacement pivot entry door. When contemplating replacing architectural pivot entry doors, management is faced with having to deal with the entire process all over again in hopes of a better resulting outcome. The replacement of architectural pivot entry doors is the result of the complexity of building a pivot entry door that is less likely to fail, or to fail less than its predecessor. This is why pivot entry doors, especially if they are over 8 ft. tall are excluded from warranty of the pivot door company at the time of installation (see your contract paperwork for the exclusion).

No other large pivot door solution can match the power of Sing Core. Here’s the latest straight talk about pivot doors:
Pivot Doors Straight Talk
As the demand for large pivot doors is on the increase, the bigger they are, the more impressive they are, also, the more apt they are to fail due to door warp. Let’s face it, a door that is not straight and true is of little use as a door at all.
It is imperative for large pivot doors to remain straight and true, and the design team at Sing Core has created a full battery of patented and patent pending solutions to keep any large pivot door, made of any material perfectly straight, far exceeding AWI standards for flatness. The true flat experts at Sing Core have the knowledge and ability to create large pivot doors will not warp, eliminating the biggest complaint about pivot doors.
So, if you want a straight pivot door, the only way to get one made and guaranteed to remain warp-free for 50 years is to do what most contemporary architects, designers and engineers do, and that’s to specify that you want your doors to have, “Sing Core inside.”
Pivot Door Problems
Large pivot doors with Sing Core inside also solve other problems facing architects and designers, including, but not limited to…
Heavy Pivot Doors
Large pivot doors are big and heavy in weight. The large size and the heavy weight is problematic for a number of reasons. First of all, you must find a custom door manufacturer or millwork to take on such a project in the first place. Anything that is large is going to be difficult to create and manipulate through the building process just to create the mammoth door in the first place. Then you have to be able to move the door from the factory to the truck, using a combination of manpower and heavy equipment. Then transport the large pivot door from the factory to the job site. Once at the site, more manpower and heavy equipment is required to unload and move the door to where it will be installed. Installers now have to deal with the door, moving and fine tuning it to fit the space and attach the appropriate heavy duty pivot door hardware which can cost many times the price of the pivot door.
Heavy Duty Pivot Door Hardware
Expensive heavy duty pivot door hardware is required as the hardware is determined by the weight of the door. Even though this hardware is designed to handle a heavy weight pivot door, the straight talk is, if the door is used regularly, the hardware will start to breakdown and fail over time.
Large Pivot Door Maintenance
Which brings us to maintenance on the large pivot doors; yes, your large pivot door is impressive and leaves a great first impression but the more consistent lasting impression is left upon the pivot door’s owner who must bear the cost of constant repair and maintenance over the life of the otherwise magnificent large pivot door. As huge pivot doors are used, they cause stress and strain, not only on the hardware, but also the structure, creating the need for maintenance and repair on the pivot door for warp, the hardware as it deteriorates, and the structure for stress and strain.
Large Pivot Door Insulation
In most large pivot doors, little thought is given to the insulation value of the door. While large pivot doors are commonly thicker than their hinged cousins, the large pivot doors may not provide for energy efficient handling of thermal separation or elimination of sound penetration.
Large Pivot Door Danger
If you have a large pivot door, operating it may be problematic, especially when delicate little fingers are around when the pivot door is opened and closed. Large pivot doors are so heavy that there is the danger of injury to anyone, not just children, when the doors are in motion.
Pivot Door Solutions
Thanks you Sing Core, you can save money and have a better large pivot door experience over time, as the Sing solution is applied. Here are some of the solutions you can expect by specifying that your pivot door has, “Sing Core inside.”
Lightweight Pivot Doors
If your pivot door is built with Sing Core inside, it can weigh a fraction of the weight of any other solid core pivot door. The energy savings in just the creation and transport of your Sing pivot door help to make it more ecologically responsible, using less energy to create, ship and handle. But there’s more…
Lightweight Pivot Door Hardware
Because the type of pivot door hardware is based on the pivot door’s weight, a lighter weight door requires a pivot hinge which is matched. Real cost savings can be realized by being able to use the less expensive pivot door hardware, bring the cost of the hardware way down.
High Strength Pivot Doors
Your Sing pivot door is very strong as it was university-tested and rated at 660 PSI in strength, making it stronger than steel pound for pound. This superior strength is due to the patented insulated reinforced vertical grain torsion box core. Without Sing Core inside , you are limited to the ability of the material used to maintain the pivot door integrity over time.
Sing Pivot Door Maintenance
When your pivot doors have sing Core inside they are also nearly free of regular maintenance. If you have a professional Sing pivot door that does not warp, then you possess a large pivot door which can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years. Plus, if the door is damaged for any reason, it can be quickly and easily repaired on site (often without have to dismantle or remove the door) without compromising the pivot door’s strength or integrity. In addition, the lightweight of your Sing pivot door, means much less stress and strain on the hardware.
Sing Pivot Door Installation
Being so lightweight reduces costs and time by being so lightweight. Due to the bulky size several people will need to manipulate the door, but no heavy equipment will be needed because the crew can easily maneuver the large pivot door without much trouble. In fact, we commonly hear back from the installers about how they couldn’t believe how light and easy to work with large pivot doors with Sing Core inside are.
Insulated Pivot Door
Sing Core pre-packs your large pivot door with insulation wall to wall inside the torsion box structure imbuing your large pivot with increased ability for climate control and also sound deadening capabilities that are hard to find in other large pivot doors. If you’re thinking about separation between room, or particularly a pivot front door, the added insulation factor is of huge benefit and included in every Sing pivot door blank at no extra charge. Insulation upgrades are available per your specification.
Sing Pivot Door Safety and Security
Due to the increased insulation and high strength of your pivot door that has Sing Core inside, you can enjoy a greater sense of safety and security. The high strength will prevent breaching the door from unwanted guests. These are often used as impact doors. If you kick other lightweight pivot doors, they could easily fail and offer egress to an otherwise secure environment, but if you kick a Sing pivot door you will not break the door. You are more likely to break your leg and the sound deadening characteristics inhibits eavesdropping.
In the event a child, or anyone, gets their hand or fingers caught in a Sing large pivot door in motion, the likelihood of surviving such an event is much more likely as less damage will occur thanks to the Sing solution being so much lighter in weight than other large pivot doors.
The lightweight and high-strength attributes of SingCore are spanning the globe as designers, architects, and project managers continue to specify their projects have, “SingCore Inside.”
SingCore is the secret ingredient in building projects – especially those of large size and components with long spans – where certain challenges become apparent in translating the creator’s vision to real life.
Many problems associated with large, oversized projects or elements become apparent when attempting to bring an original design to life, mostly concerned with weight and strength.
Until now, very strong building materials were heavy in weight. This extra weight creates problems for the structure in terms of stress and strain over time. Lightweight building materials may be substituted for the stronger heavy ones, but compromises are made which may compromise the strength and integrity of the project.
This is the quandary facing development teams and precisely the point where SingCore provides the solution to the problems facing developers of large projects.

37 ft. Tall Pivot Doors
If you’re designing a conference center with 40 ft. ceilings and need a row of 37 ft. tall pivot doors to act as room dividers, you are going to be faced with the issues concerning strength vs. weight. In order to keep the 37 ft. tall doors from warping, your design team is faced with the challenge.
If you dared to think, “What if I could have it all?” If it were possible, you would like to have insulation for its sound deadening qualities and climate control. Then you could just hang insulated baffles, but you would compromise the function of have pivot doors and they could easily fail as they have no strength.
Problem solvers would suggest that aluminum or steel could solve the problem, but the weight of a 37 ft. tall pivot doors would be very, dangerous to install and very expensive for the 37 ft. tall pivot doors, as well as the heavy duty pivot door hardware, which would probably cost many times the price of the large metal door itself.
This is the common paradox facing the designers dealing with the weight vs. strength issue, especially in large doors.
This is where SingCore shines as it rescues the plight of engineers and contractors fervently attempting to bring the designer’s vision come to life. SingCore is the only Eco-friendly, insulated lightweight, high-strength building material that outperforms other lightweight building materials so much, that it is the only material that can be used to build a large non-warping door of any size in any application.
Insulated Strength and Rigidity
SingCore is the provider of highly advanced high precision panels, posts and beams for high-end applications and clients all over the world. These patented building materials are unique in that they are lightweight, stronger than steel, and insulated for R value and sound deadening STC levels.

It is now not only possible, but proven, that you can build a warp-free door of any available flat building material – even as problematic a building material as natural wood grain – and have the resulting door be guaranteed not to warp, bend, twist or otherwise fail for 50 years.
No other door can compare to the insulated lightweight strength of doors with Eco-friendly premium SingCore inside.
The weight of SingCore is easily one-third the weight (50% to 87%) of solid wood.

In most cases, a large pivot door is very heavy in weight, this requires additional shipping, handling and may require additional heavy equipment to handle the large pivot door on site as well as requiring heavy duty pivot door hardware which based on weight can be many times more expensive than the large pivot door itself.
When your large wood plank pivot doors have SingCore inside, they can weigh-in at 3 lbs. per sq. ft. Your 10×10 pivot door could weigh 300 lbs.
* SingCore pivot doors may vary considerably due to individual weight of architecturally specified materials
Many exterior doors – especially wood exterior doors – are problematic due to the nature of being exposed to the weather and environmental changes of heat and moisture. Exterior facing doors become even more challenging if they are over 7 ft tall or 3 ft wide.

The best proof is large wood exterior doors facing both Pacific and Atlantic oceans, as we work with the best door companies from coast to coast in the USA. In this example, the exterior wood doors in this home are all perfectly straight on these weatherproof non-warping doors, even though they feature wood stave on the exteriors exposed to the moisture, sun, wind and rain of coastal weather patterns. Still these doors can be fully guaranteed not to warp, bend, twist or otherwise fail (including structure) for a full 50 years. That’s right
Guaranteed for 50 Years
Large 14 ft x 12 ft exterior opening with (2) 14 ft x 6 ft insulated hinged doors
Large garage doors are the best example of what can be possible with would have previously been thought of as impossible doors. That is to say doors that were too large were assumed to have problems because all big doors fail. Even so, to minimize failure, they are manufactured using very heavy materials and expensive hardware to mitigate the failing doors, only to add more stress and strain on the existing structure. In this regard, the big door business is lucrative, due to the ongoing maintenance contracts associated with large door problems.
True space separation between two adjoining areas (i.e., interior and exterior) is a difficult expectation for any door. Even though a door might looks attractive from a distance, the truth of the matter is seen from the other side of the door. The built-in insulation inside the patented Sing door core not only provides effective climate control, but offers advanced sound deadening qualities. Sing door cores have been used inside soundproof doors and everything from bulletproof doors and fireproof doors.
Why waste energy by having a door that doesn’t seal properly as your exterior door? Everyone knows that a good door seal helps prevent energy loss saving on energy consumption. Having warp-free doors means your doors seal properly without leaking every time, regardless of the season, temperature or time of day. You can save energy – not only from the insulated that is packed inside for better temperature control – but also from having a secure door seal that does not fail due to warping, if your door has SingCore inside.
Sliding Door or Pivot Door
Reduced to its simplest form, these insulated warp-free doors could also be exterior sliding doors and/or exterior pivot doors with all the same great characteristics that come with having SingCore inside.
Only SingCore can accomplish all this – and more – providing you with the strongest, lightweight, insulated door core that can be guaranteed not to fail for a full 50 years , including warp-free and structure guarantee. No other door company can guarantee their doors, like that, unless they have SingCore inside.
If doors with SingCore inside can obtain such high performance standards as exterior doors, imagine having doors to match throughout your entire house, because our patented door core also makes the best interior doors for your home’s inside points of egress. If we can guarantee your exterior door for 50 years, we could guarantee your inside doors for 100 years.
We are the manufacturers of SingCore. We do not sell retail. We only supply the best architects, builders, manufacturers, millworks and door companies with patented SingCore products that lift and redefine the limitations of weight and strength in building materials such as doors, panels, post and beams.

Oversize Entrance Pivot Doors
“If we could build this giant warp-free wooden pivot entry door, we can build your door.” ~ Peter Sing
For thousands of years pivot doors have been the upscale preference of the most exotic high-end large oversize entrance doors relying heavily on the entry door hardware, specifically the pivot hinge, to manage the functionality of the pivot door.
Due to the size and weight of the conventional modern pivot door the heavy duty hinges and pivot door hardware could account for up to half the cost of the pivot door (e.g., a low end pivot door could cost $3,000, half the price will pay for the hardware due to the heavy weight), creating a high price point as well as being expensive to transport, handle and install.
Yet, the most demanding clients desire this elegant outswing exterior door to make an extreme visual impact for the primary access point of their structure (while bringing the outside in and the inside out by way of the architect’s modern design concept) regardless of price to command attention via first impression.
Pivot doors may be the most expensive designer doors but there’s no escaping the luxurious feel that they lend to designs by top architects who help to create the most leading edge structure designs by featuring the best exterior doors.
Since hardware is of huge importance in a pivot door’s design and implementation, there are many options to consider including offset pivot hinge, commercial door hinges, heavy duty door hinges and center pivot door hardware in your pivoting door system.
High precision—-Sing core tolerance within .+ or – .007 inch
High strength—Sing door panel could design reach beyond 700 psi vs other lightweight core average 10 to 50 psi.
Less hardware and install cost.
Safe for kids to operate.
Warp-free and structure guarantee for 50 years
The best large door guarantee in the world ~ make sure to ask the door supplier for warranty if you have a large door to be built.
You do not want to have a problem if investing in tens of thousands of dollars in your high end door. Patented and patent-pending SingCore door panels will make Sing clients less worried about door warping or lack of structure strength over time.
Many pivot doors feature metal structures and framed composites and more popular for exclusive high security environments, commercial steel entry doors and even residential steel entry doors.
How to Build an Exterior Door
Many considerations must go into the design, plan, building and installing a pivot door.
1. The Core Material
The core material that makes up the heart of your pivot door determines so much. Based on your choice of material you will determine your pivoting door’s:
2. The Frame
Will your pivot door be a solid one-piece material construction, or will it be framed or unframed?
Many options about for the substance of your pivot door, first – the most heavy and likely the most unstable – is solid construction, then framing. Framing your pivot door can be with wood or metal, like steel or extruded aluminum. Wood will move Framing with metals, like a conventional steel door, may not meet high performance specifications due to welding creating imperfections in the metals.
3. The Entry Door Styles
What will the general appearance of your door be? What exterior surface material, skin (see material options) or design will make your pivot front door stand out to make that impactful visual impression?
What hardware will be required (price is usually influenced by style of pivot and finished weight of door) for optimal performance of your pivot door?
Who will install your pivot door and will any special handling/equipment be required for installation?
Can the Affordable Pivot Door Replace Contemporary Entrance Doors?
Until now, pivot doors have generally been too expensive for the average homeowner to consider, but one pivot door core material is changing all that. Sing Core manufactures an Eco-friendly pivot door core material used by the most high-end architects, designers, door manufacturers, millworks and contractors for building the best pivot doors in the world.
What constitutes the best pivot door in the world? One that is:
1. Eco-friendly (sustainable, true green)
Sing Panels are constructed with natural wood fiber vertical grain torsion box filled with recycled rigid foam adhered between stress skins using formaldehyde-free glue for a solid substrate.
Sing Panels weigh a fraction of the weight of other solid structural building materials.
3. High strength
Sing Panels were independently tested by the University of Washington at 660 PSI for super-strength (compared to 10 to 110 PSI of other honeycomb cores used in the aerospace industry).
Sing Panels are packed with insulation rated at R 3.5 to R 6.5 (depending on foam selection) and feature sound deadening qualities for security and privacy.
5. High Precision
Only Sing Panels can be created to be true flat, within .006 inch tolerance with little or no deflection.
Sing Panels can feature any surface material (skin), like any wood species, aluminum, ceramic, concrete, fiberglass (FRP), HPL, Kevlar, LVL, MDF, stainless steel, stone or any other flat building material, may host any glass lite openings in any configuration and can be embellished to have the appearance of any style door imaginable.
7. Guaranteed not to fail
Only Sing Professional pivot doors can be guaranteed true flat and to stay flat and not to fail for 50 years. (See free consultation).
Only by using patented Sing Core can any pivot door achieve such results.

How Can I Get a Sing Pivot Door?
There are many ways that you can make your pivot door dreams come true.
Architects have access to Sing technology and are specifying Sing Core in their pivot door designs – especially if they are large pivot doors – that can be manufactured by their favorite millworks.
Most one-of-a-kind custom pivot doors are created by revered craftspeople and woodworkers who create hand crafted pivot doors for exclusive clientele.
3 Door Companies
Any door company can use Sing Panel as the substrate for your pivot door. Though many do not feature the Sing Pivot Door as a standards catalog item, in most cases you can special order your pivot door with Sing Core technology.
Sing pivot doors panels are sold without hardware installed and unfinished. Our door panels are manufactured for mill works to install hardware and finish. We do not recommend shipping Sing door panels the job site for installing hardware and finishing. This is not the best way to treat a high end door such as a large pivot door made with SingCore. We highly recommend the GC work with millwork professionals to finish at their facility (except some special restrictions).
We believe each professional has it’s own specialized knowledge just like we do not expect an architect to install the door, instead using a highly trained GC.
Since the weight of your Sing pivot door will be a fraction the weight of a solid (or framed) pivot door you can save cash that would have to be invested in heavy duty pivot door hardware that could account for half the cost of any other pivot door.
Plus you save on transportation and installation costs, just like our clients (see clients list) and enjoy maintenance-free high performance of your pivot door.
