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.

Structure of Pivot Door

1. Steel frame

Large modern pivot doors with man door lightweight high strength Seattle center
  • Very heavy
  • Expensive to install
  • Expensive hardware due to the Weight
  • Less thermal break
  • Less precision due to welding process
  • Less compression strength which could cause surface dent under impact

See: Center for Architecture and Design Seattle’s large custom edge pivot doors w/man door (Sing Core is a platinum supporter). 

2. Wood frame and/or solid wood pivot door

  • Not strong
  • Heavy
  • Danger for kit to operate due to the heavy weight
  • Less compression strength on the surface of the door—-potential structure after years of use.
  • Potential to warp, twist, cup, bend
  • Lack of high precision—which cause the leak of air, latch have problem to close or does not have a close tolerance to lock the door in place
  • High cost for hardware and installation
  • Lack of insulation

3. Frameless (don’t be framed)

  • Small grid torsion box
  • Lightweight core panel/sandwich core/honeycomb core
  • 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

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:

  • Weight
  • Strength
  • Insulation
  • Precision
  • Performance
  • Maintenance

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?

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.

2. Lightweight

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).

4. Insulated

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.

6. Versatile

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.

1 Architect

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.

2 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.

4 Contractor

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.
