Pivot Hinges for Doors

Making its way into modern architectural designs across the USA and throughout the world abroad, pivot hinge doors are marking their territory, especially when the client or homeowner desires to make an impact at first sight of the dwelling’s pivot front door. Not to be only dominating the upscale housing market, high end commercial establishments are also seeking out a large, unique pivot hinge door to welcome their clientele. This leaves the playing field wide open for pivot door manufacturers as well as the hardware companies supplying pivot hinges for doors throughout the industry.

While the pivot door market is growing by leaps and bounds, finding a pivot door company that specializes in pivoting doors, especially large pivot doors, is still hard to come by. Why? Unlike other side hinge doors, pivot hinges for doors that pivot are another type of door altogether.

Pivot hinges for doors

The pivot hinge door has two pivoting points where the pivot hinge is located. One on top of the pivot door, and one on the bottom of the pivot door. The center pivot door (indicating the center hung pivot hinge’s location in the door) is by far the most traditional location of the pivot door’s pivoting hardware, thought the current trend is to feature an offset door pivot hinge.

In the case of the offset pivot door, the pivot hardware is located to the left or right of center, or in an extreme edge pivot door the door pivot hinge is located closer to the outside edge of the door. This not only offers a unique visual impact of having an offset pivot door, there is also the advantage of having a wider opening when the door is in its opened position. With the offset door pivot hinge, the pivot door is not limited to one half of the pivot door’s frame, which provides more open access when using pivot hinges for doors that are offset (to one side of the center of the pivot door, or the other).

There is no doubt the pivot hinge doors is staking its claim on the front facing home as a pivot front door. The responsibility of the pivot front door is greatly escalated, as an exterior door one side of the pivot front door faces the elements, while the other side of the pivot door faces the home’s interior. This is asking for door trouble from the get-go, as front doors, especially for wooden pivot doors, due to their tendency to warp, bend or twist under these extreme circumstances.

There is one solid solution to the problems associated with large wooden doors used as pivot entry doors, and it is none other than Sing Core. If your pivot hinge doors is built with Sing Core inside, your pivot door will weigh in at a fraction of the weight of other pivot doors, while remaining extremely strong (660 PSI, stronger than steel pound for pound). So strong, in fact, that your professional Sing pivot door can be guaranteed to remain warp-free for 50 years. That means you don’t have to worry about you’re your door’s tendency to bend, twist cup or otherwise fail, including a full structural guarantee for 50 years. No other sustainable, Eco-friendly, lightweight, high strength door can be backed with such an amazing guarantee.

Pivot doors prices can be very expensive doe to the nature of the doors to warp, and many steps have been taken in the past to keep these pivot doors straight, but at what cost? Adding an interior frame that is resistant to warp, like aluminum or steel may well keep the pivot door from warping but the pivot door then becomes very heavy, and heavy pivot doors mean heavy duty pivot door hardware.

When you’re staring a pivot hinge heavy duty in nature, you’re facing a large ticket item, as heavy duty pivot hinges can be very expensive indeed. If a pivot door is heavy, it is not unusual for the pivoting hardware to be many times the cost of the pivot door itself.

Think of all the savings which may be realized by having your pivot door built with Sing Core inside. You will save in shipping and transport, as well as installation, hardware and continued maintenance over time, because you have a lightweight Sing pivot door, without having to compromise in precision or high performance.

If you have a Sing professional pivot door, congratulations, you could have the best pivot door available today.

Pivot Entry Doors | Pivot Door

With the prevalence of pivot doors | pivot entry doors are being included in high profile contemporary architecture design, the most impressive pivot entry doors are oversized. These large pivot doors are generating a great deal of inquiries to one pivot door company for solutions to a variety of challenges associated with the large pivot entry doors.

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).

Large Pivot Doors

21 ft. tall large pivot door

There’s no doubt about the growth in the pivot door market. Just a few years ago pivot doors were the exception to the rule, today more and more people want to make an impact statement by featuring a pivot front door, and nothing packs more curb appeal than large pivot doors, leaving an everlasting impression. In fact, the bigger the pivot door, the better.

You know what having a large pivot door means? You got it = large prices, on everything. Everything is more expensive when you’re dealing with a large pivot door. Think about it… Large pivot doors are large and thick, that means they’re cumbersome and they’re hard to manage on the job site, sometimes requiring extra heavy equipment just to move them about the site. Of course, they are heavy, which means transportation is going to be expensive, as well as the heavy duty pivot door hinges (also expensive) because the weight of the large pivot door determines which hardware is needed to support the extra weight.

The extra weight can be a problem if it is being used regularly, causing extra strain on both the hardware and the structure itself; resulting in costly maintenance and repairs to the pivot door and the structure as well over time.

But wait, there’s more: Since everyone wants to have a large pivot front door that means one side of the door faces the structure’s interior while the other side is exposed to the elements, and you know what that means? You got that right: Warped doors! When is a door not a door? When it’s so warped you can’t secure it. There you go = more costly repairs.

What If…

What if one type of large pivot door could overcome all the hassles associated with other large pivot doors. I mean, if the laws of physics could be suspended for a moment, and you could have a large pivot door any way that you wanted it, what would that large pivot door look like?

Large warp-free wooden architectural pivot door w/50 year guarantee

Pivot Door Size

To start, size would not be an issue. You could have any size large pivot door in any thickness you wanted, without having to make a zillion calls to find anyone who would undertake such a challenge.

Pivot Door Options

You would want to be able to specify any material to have the large pivot door manufactured out of, and it wouldn’t matter if it was concrete, natural and/or exotic wood, including any metal from aluminum to hot rolled steel, or any other available flat building material. You could have whatever you wanted.

Lightweight Pivot Doors

If you could have it any way you wanted it, you would have this large pivot door weigh a fraction of any other pivot door, so that you could reduce transportation, installation and hardware costs at the get-go, as well as having less expense over time, because the lighter weight means less stress and strain on hardware and structure, and less maintenance costs.

High Strength Pivot Doors

If the large pivot door is going to be lightweight, we do not want it to be wimpy. I want to know my family is safe a secure from forced entry, and if someone tries to kick in the pivot door, I want them to break their leg. And if I accidentally drive a pair of forklift forks through it, I want to know that it’s strong enough to take the impact without compromising the pivot door, and can easily be repaired (without having to remove the large pivot door).

Warp-free Pivot Doors

Might as well throw in the idea of having a large pivot door with superior warp resistance; how warp resistant would you want? Okay, let’s say it. We want a door that does not warp, period, even if it is used as an exterior-facing pivot front door.

Pivot Door Insulation

Just for fun, we might like to throw in the idea of having a large pivot door that is well insulated to provide more safety and security from sound deadening and energy savings to superior climate control.

Customizable Pivot Doors

I’d want to be able to customize the large pivot door any way I wanted to, including custom lite cutouts in any shape and style I wanted (not being limited to having to pick from a few options). I want it the way I want it. Can we do that?

You Can Have It All

You can have all this and more! What? Surely you jest. Nope, I am being totally honest with you. You can have everything you could imagine, like unlimited size restrictions for your large pivot doors, made out of any flat building material available, weighing in at a fraction the weight of other solid core pivot doors, yet stronger than steel pound for pound and guaranteed not to warp, bend, twist of fail structurally for a full 50 years.

Oh, and you can have all the insulation you want for sound dampening and saving energy, as well as custom lite cutouts, where you want, in any shape you like.

Now, that is the perfect large pivot door

The most exciting thing about all this, is that it is not just a fantasy, but Sing Core does actually help the best millworks and door companies to supply their customers with the very best large pivot doors available in the world today.

Large pivot doors made in the USA 50 year warp-free guarantee

How is it possible?

The large pivot door technology was birthed from the imagination of inventor, Peter Sing, whose next generation reinforced torsion box design enabled him to be able to accomplish all these feats, outperforming other aerospace-inspired lightweight core materials (rated at 10 to 110 PSI), while Sing’s core clocks in at 660+ PSI. And if you want a high precision pivot door (which is why you see Sing’s products featured from beneath the sea [US Navy] to outer space [NASA]), very few materials can be made so high precision (+/- .006 in.).

With all these features and benefits, who wouldn’t want a large pivot door with Sing Core inside?

How Can I Get A Sing Large Pivot Door?

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.

Pivot Door

large-oversize-architectural-pivot-door-warp-free-wood-doorDesigner 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

Pivot door room dividers insulated wood lightweight high strength
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.

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.

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