Pivot Doors Straight Talk

Years in the making, finally Sing Core has come out with the ultimate solution for Eco-friendly pivot doors made of any material and any size weighing a fraction of other door cores. This revolutionary patented solution has made Sing Core the number one resource for large pivot doors that are lightweight, high strength and can be guaranteed to remain warp-free for 50 years, as well as full structure warranty. 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

The only 50 year warp-free guarantee and full structure warranty

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.

Shouldn’t your pivot doors have Sing Core inside?

How to Find the Best Pivot Doors

Whether you’re a home owner, project manager, architect, millwork or door company, you might like to find out how to get the best pivot door, especially if you’re going to spend $10,000 or more on your pivot door.

The only 50 year warp-free guarantee and full structure warranty

Best of the Best Pivot Doors

The best pivot door manufacturers, who provide the best pivot doors with the best pivot door warranties are able to provide their clients with the best pivot doors that can be guaranteed not to warp, bend, twist or otherwise fail for 50 years, if the pivot doors have patented Sing Core inside.
Door manufacturers can provide you with the best pivot doors, and this might be true, if their high end doors have Sing Core inside (and you can have your pivot door protected by our 50 year guarantee).

Check the Pivot Door Guarantee

High quality high end doors will come with a guarantee to ensure the customer’s satisfaction. Most large pivot doors do not come with a guarantee because they are problematic and have a high potential for warping, especially if the pivot door is an exterior pivot door.

You might be like to know what features to look for in the best pivot door, so that you can adequately determine what the best pivot door looks like and you can then review potential pivot door and made a decision based on your own due diligence.

In case you didn’t already know, it’s important to know how and why pivot doors fail.

Is your Pivot Door Likely to Fail?

Most pivot doors will fail doe to either the pivot door warping, or delaminating (structure). A composite pivot door (anything other than a heavy solid slab of flat material) will fail due to stress or environmental conditions. Any undue stress or strain on your pivot door, i.e. regular use straining both the hardware and the supporting structure (causing increased maintenance over time) or exposure due to unforeseen circumstances (like accident or abuse) may cause the door to fail or delaminate in response to impact.

What to look for in the best pivot door: Lightweight and structure warranty

Large Pivot Doors Are Prone to Failure

The Architectural Woodwork Institute issues and maintains minim requirements for warping doors which allows for up to ¼ inch of deflection or door warp over a 7 ft. span. Knowing that all doors warp, is helpful when reviewing your expectations in regards to pivot door warping. A warped door seven feet tall is likely to warp up to ¼ of an inch regularly, which is allowable in door warranties.

What to look for in the best pivot door: Oversized, large pivot door warranty

Exterior Pivot Doors Are Prone to Failure

Exterior pivot doors have a higher risk of failure due to door warp because one side (the inside) of the pivot door faces a temperature controlled interior space while the other side is exposed to the elements which cases the pivot door to move (warp, bend, twist, cup) resulting in pivot door failure. If a pivot door cannot freely swing or seal due to being warped, the may not be able to latch or operate as a door due to air leaks around the pivot door.

What to look for in the best pivot door: Exterior pivot door warranty

Why Pivot Doors Fail: 1. Door Warp, 2. Heavy Weight, 3. Structure Failure, 4: Size.

The characteristics you want to look for in the best pivot door include:

1. Warp-free, 2: Lightweight, 3: Structure Guarantee, 4: Available in any size, 5: Long life guarantee

So, if you know what you want in a pivot door, why not Google what you want and see what you get?

We Do Not Have Pivot Doors for Sale

We do not have pivot doors for sale, because we do not make pivot doors. Our pivot door blanks are used by door manufacturers and millworks to build the best pivot doors. Our patented Sing Core is the only high precision pivot door blank material that can be guaranteed not warp or fail for 50 years.
You can have the best pivot door with the best 50 year pivot door guarantee just by contacting your favorite millwork, custom door manufacturer or door company and tell them what pivot door you want and ask for, “Sing Core inside.”

That’s what we do. We work with the best pivot door manufacturers to make the best pivot doors that have the best pivot door guarantee for 50 years, because your pivot doors have premium Sing Core inside.

That’s why the best contemporary architecture design specifies, “Sing Core inside,” in the most important high end projects, especially when there are large pivot doors requiring high performance expectations over time.

How to determine if Your Pivot Door is the Best of the Best?

1. Warp-free

See the minimum warp allowances for pivot doors below. Pivot doors made of patented Sing Core far exceed the warp resistance allowed by AWI standards. In fact, one of the largest high end door manufacturer comments, “We have not had a single door fail since we started using Sing Core door blanks.”
All the latest multi-million dollar homes are using large pivot doors in their contemporary architecture design. Please inquire with your favorite trade professional as to which pivot doors can be guaranteed to remain warp-free for more than one year. Patented premium Sing Core doors can be guaranteed to remain warp-free for 50 years.

2. Strength

Patented Sing Core is strong enough to withstand the impact of a sledge hammer without causing structural damage. See the unbreakable mirror test, which demonstrates a mirror backed by Sing Core which does not break under the direct impact of a 16 oz. hammer. Your high strength door with Sing Core inside will survive years of use and impact without distortion or structure failure. Patented premium Sing Core is fully structure guaranteed for 50 years.

3. Lightweight

Some of the largest pivot doors could weigh a ton in an attempt to obtain strength and warp resistance but not doors with Sing Core inside. Patented Sing Core weighs approximately 10% of solid wood, timber or plywood core. Products made with Sing Core are stronger than steel pound for pound. Lightweight pivot doors are safer for kids to operate, plus it costs less for hardware, transportation, handling and installation and will not sag after years of use.

4. Eco-friendly

The torsion box structure of patented Sing Core is responsibly and sustainably made using renewable vertical grain natural wood fiber which comes from nature, unlike other less strong core materials made of paper, aluminum or solid wood-based cores.

5. Insulation

Patented Sing Core is packed with insulation which imbues the pivot door with qualities such as climate control and sound deadening characteristics, which is even used in bullet proof and impact doors. High R value and STC rated* insulation material is also a key component in the solid composite substrate which helps to achieve the high performance standards of Sing Core.

“It would have not been possible if not for Sing Core.”

The unique patented vertical grain torsion box/insulation-packed composite substrate expands the possibilities of building materials, bringing the visions of architects and designers to life and is the only Eco-friendly product known with such lightweight (10% the weight of solid wood) high strength (660 PSI) ability to span long distances with little or no deflection, even under stress and strain over a long life of heavy use.

Ask your favorite architect, millwork or custom door manufacturer about Sing Core.

* Note: STC rating varies according to size, thickness, skin, and other factors. Sing Core does not rate doors, although we are fortunate enough to have one of the best sound testing labs in the world, here in the Pacific Northwest. If you require a specific STC rating, Sing Core can build a door to your architectural specifications and have the resulting door tested at our rating facility for an official rating.

About Pivot Doors with Sing Core Inside

Pivot doors which are made using the patented and patent-pending Sing Core technologies are celebrated around the world as being the best pivot doors in the world.

Why Do You Need Sing Core Inside Your Pivot Door?

Pivot Door Problem

Its well-known pivot doors fail more often than hinged doors because there’s only two points of contact on a pivot door. On a hinged door there are three or more anchor points on one side of the door to help keep the door straight. If a pivot door warps, bends, twists, or cups, the operation of the door can be severely compromised or fail altogether. If you have a large pivot door (over 7 ft. in any direction) failure is far more frequent.

Pivot Door Solution

THAT is why you need Sing Core inside your door. Using Sing Core is the only way to build a lightweight pivot door that is stronger than steel which comes with a full warp-free and structure guarantee for 50 years.

Designers and Architects are establishing a new trend in the architectural impact of structures that garner attention at first glance by greeting visitors with a large pivot door. The larger the front pivot door, the more impressive and attention-grabbing.

Large pivot front doors create the greatest impact when a structure is seen for the first time. These oversized pivot door are big and thick, and the bigger the better. These big pivot doors are taller, wider and heftier than other traditional front door styles. Even real estate developers are installing large pivoting entry doors in high end homes for that extra hit in the curb appeal presentation.

Though some door manufacturers build and stock standard pivot doors, ready to install, the high end large pivot doors are custom manufactured for each installation by millworks, craftsmen or custom door manufacturers. Each pivot door is like an individual work of art.

Pivot Door Swing

Large extreme edge pivoting hardware for large swing wooden room dividers with man door Pivot doors are often thought of as having a center pivot point. A pivot door with a center pivot defines the maximum access as basically on-half the door width, because in the fully open position, the pivot door blocks the center of the opening due to the location of the pivot. Large pivot doors may be no problems as a 10 foot wide pivot door can still have a 5 foot access opening.

Center pivots are not your only options when considering a pivot door, as the pivots can be placed at any location. Moving the pivot point of your pivot door more to one side or the other creates a greater egress area on one side than the other. For maximum opening, an extreme edge pivot point can be used for your pivot door, so that it operates very similarly to a swing hinge door. Example: 10×12 extreme edge double pivot doors in the Center for Architecture & Design, Seattle, Washington are each twelve feet wide, five inches thick and open for a full 23 feet of access (also feature a man door for easy access when in the closed position).

Tall Pivot Doors

21 ft tall edge pivot doorA large pivot door can span from floor to ceiling of any structure as well as being very wide and thick.

Pivot Sliding Door

Another growth segment in pivoting doors is a method that combines the best of two types of door hardware to develop a pivot sliding door using multiple floor to ceiling pivoting door panels alternatively hinged and retrofitted in sliding door hardware to produce large accordion door wall systems. These pivot sliding door wall units create complete separation between any two rooms, functioning as folding stacking doors, yet when fully opened reveal one large space.

Pivot Door Materials

Pivot doors can be made of any flat building material including materials that would be impossible to make a hinge door due to the weight. The design of the pivoting hardware can accommodate a pivoting entry door that is many, many times heavier than any hinge door.

Large pivot door can be manufactured using available materials such as cement, metals (aluminum, cold rolled steel, copper, galvanized steel, hot rolled steel, stainless steel, steel diamond plate, etc…), natural or exotic woods (alder, bird’s eye maple, cedar, cypress, mahogany, olive, redwood, walnut, willow, etc… ), stone (granite, limestone, marble, sandstone, slate, etc…), just to name a few.

Heavy Pivot Doors

Though large pivot doors can span from floor to ceiling and the pivot door hardware can handle heavy weights, the challenge to overcome is the obvious one: The large size and heavy weight can create problems over time causing the need for routine ongoing maintenance dealing with issues that compromise either the pivot door or the structure itself.

Heavy pivot doors can cause undue stress on both the hardware and the structure, requiring maintenance on the pivot hardware, frame and possibly the structure under regular heavy use.

Light Pivot Doors

One way to optimize large pivot doors for weight is to use a strong lightweight substructure that will not compromise the structure of the door. SingCore large pivot door substrate is perfectly designed for large pivot doors sporting additional features besides creating a solid composite door that weighs a fraction of an otherwise solid door. How else could you make a lightweight 16 ft. tall white oak pivot door (like the one to the right) that can be guaranteed not to warp for 50 years? You can find 8 of these doors on the top floor of One World Trade Center, NY.

Modern pivot doors with patented SingCore inside are strong (660 PSI, stronger than steel pound for pound) and the torsion box structure grids are packed with rigid insulation (for added R-value and sound deadening capabilities).

Using SingCore inside your pivot door can transform any heavy pivot door into a lightweight pivot door.

Large Pivot Doors Warp

Warping large pivot doors are one of the chief problems associate with large pivot doors – or any large doors, for that matter – especially if the large pivot entry doors are made using natural woods, which are elegant when installed but tend to move according to variances in heat, moisture and other environmental conditions.

There’s really no way around the natural characteristics of wood grain to bend, warp, cup or twist – that is – until now…

Guaranteed Warp-free Large Pivot Doors

Only large modern pivot doors with professional SingCore inside can be guaranteed to remain structurally sound and warp-free for 50 years.

Wood Stave vs. Wood Ply

Wood stave doors can be very costly to make, especially if you’re looking for a lightweight high strength solution for a warp-free guarantee for 50 years. Using Sing Core inside your wood stave door featuring wood planks from 1/8-inch to 1/2-inch will create more potential for warp due to the nature of natural wood grain. This is the beauty of the more economical wood ply option for building your wood door. Wood ply is far less expensive and has alternating grain orientation which also helps to keep the door straight. Wood plywood is just like any other plywood except for its featuring a particular wood grain predominantly on the surface, and it offers far more strength and reparability over time than a less expensive wood veneer.

So, if you’re looking to attain similar visual results of a solid wood door at a fraction of a price you might consider having Sing Core inside your wood plywood door. Be certain to specify what type of natural wood plywood your want, if it is available, you can save thousands of dollars on your beautiful wood door. The most popular wood plywood features woods such as white oak plywood, maple plywood, oak plywood, mahogany plywood, walnut plywood, Douglas fir plywood, knotty pine plywood, and birch plywood just to name a few.

That’s 50 years of high precision, high performance, low maintenance enjoyment of your breathtaking very large pivot door, guaranteed.

Some installations include electronically articulating wall components using automatic door hardware with optional remote controls.

Pressure Walls

While some people are using our standard torsion box panels as components in quick and easy pressure walls, our friends in the greater New York area are feeling the crunch of building codes being enforced, especially in Manhattan. For these people, they are reaching out for using our insulated panels as backing for shelves, creating a

Bookcase Wall

Even though bookcase walls are trending now in New York, designers, architects and engineers have been specifying SingCore as the backing material for bookcase walls for increased insulation and room separations when in use as a room divider disguised as a bookcase. In fact, entire bookcases built of SingCore can be easily pivoted with a standard pivot door hinge and used as a temporary wall or secret door which could be opened when desired or necessary, not just as the bookcase wall nyc.

Moveable Storage Unit Wall

The next step in alternative wooden room dividers is utilizing SingCore to build full modular storage units on wheels to make and create not only moveable storage components but to create sound deadening and functional room separation. Thanks to the lightweight and high strength these storage units can be moved around on furniture casters with ease.

How Does the Sing OEM Process Work?

Establishing the Need of Sing Core

There are many reasons that door manufacturers seek out patented Sing Core as their OEM door substrate; some of the most popular ones are:

Some door manufacturers are looking for ways to distinguish themselves from other door manufacturers. They seek out an OEM relationship with Sing Core to design and build an ultra premium line of doors that have unique characteristics that cannot be found by using any other door substrate material.

BIG Door

Many door manufacturers have problems with large doors (especially over 7 ft. tall) in that while they look magnificent upon installation, dealing with door warp on a regular basis is a constant maintenance cost associated with big doors.
