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 Hinge Door

Sing Core has been supplying the only warp-free pivot door substrates that allows the best pivot door companies to offer their high end clients an exterior pivot front door of any size that can be included in their standard warranty work (most high end millworks offer a warranty on their work for one year or more, with the exception of large pivot doors over 7 ft. tall which tend to fail at the first sing of climate change) because if your pivot hinge door has patented “Sing Core inside,” it is covered by our 50 year warp-free guarantee. This enables the millwork, pivot door company, custom pivot door manufacturer and their clients, all to breathe easier, without having to worry about large pivot door pivot hinge challenges.

Due to the characteristics of the Sing Core inside the best pivot doors, your pivot door can feature a pivot hinge of any type or style which may be problematic when attempting to accommodate a large pivot door without Sing Core inside. Attributes of pivot hinge doors with Sing Core inside include lightweight (a fraction the weight of other solid core pivot doors), high strength (660 PSI, stronger than steel pound for pound), high precision (+/- .006 in. tolerance), high performance (long life without fail) and Eco-friendly (made in the USA with formaldehyde free adhesives, very little energy consumption or waste, with the sustainable use of natural resources).

Large pivot doors made with the absence of Sing Core are likely to fail. This is why they are normally noted on the contract and excluded from the other items on the job covered by the contractor’s warranty.

The lighter weight of the pivot door opens more opportunities for creatively applying various pivot door hinges which make the resulting pivot door even more impressive or adding a commercial door pivot hinge. The offset pivot hinge is gaining popularity among pivot door manufacturers and by utilizing Sing Core inside your pivot door, you can save substantially due to the lighter weight of your pivot door as pivot door hinges are determined by the weight of your pivoting door. Heavy pivot doors require a heavy duty pivot hinge, while your Sing pivot door can use a lighter weight pivot hinge.

Heavy duty pivot hinges are expensive and can be many times the cost of your pivot front door. That’s another reason why building your pivot hinge door with Sing Core makes so much more sense. Pivot door hardware companies, such as rixson pivot door hardware are available in many styles including top hung, offset pivot door sets as well as the more conventional center hung pivot hinge.

Pivot entry doors can come in a wide variety of types and styles and can be made to outperform any other type of pivoting door including aluminium pivot doors, any available type of natural wooden pivot doors or even a stainless steel pivot door. Your pivot hinge door could be made from any available flat building material, including woods or metals.

If you’re tired of dealing with the constant maintenance issues with dealing with large pivot hinge doors over time, then maybe starting off at the right place would be your most advantageous move by specifying your door has, “Sing Core inside.” If it’s too late, and you’re already struggling with problematic pivot hinge doors, no problem. Sing Core pivot doors are the most in demand replacement doors in the United States and increasingly throughout the world, as Sing Core products are routinely exported worldwide.

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).

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.

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.
