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.

How to Build the Best Pivot Door

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

Highest Precision Maple Cutouts for Modern Pivot Doors

Steel Pivot Doors

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:

  • 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?

4. Hardware

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?

5. Installation

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.

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.

New Door Technology

Applications -> Building Components -> Doors -> New Door Technology

There is a new concept in Eco-friendly door manufacturing that raises the question:

“Is Sing Door Core a better way to build doors than any other type of door?”

New-French-Door-With-Glass-Lite-Cut-outsSing Core’s patented door core has the unique ability to build a true-flat, weather proof/water tight, lightweight door that is stronger than steel and will remain flat for centuries, covered by our 50 year true flat guarantee (compare to other door companies’ warranties that do not cover when used in exterior applications). This new technology allows nearly limitless customizations allowing clients to design any door imaginable in any configuration, style, appearance and/or feature any flat surface material. Our French doors come complete with custom lite opening cutouts to your specifications in any size or shape. Glass doors can be combined with true raised panel doors for the most high precision patented Sing door core (within .006 inch tolerance) affordable American made doors.

Sing Core is a new advancement in door building technology that is bringing door-related jobs back to America.

New Sandwich Door vs. Stile & Rail and Wood Door

SING DOOR STILE & RAIL and WOOD DOOR
Visually impressive Visually impressive
True flat Depends on wood and craftsmanship
Stays flat for centuries Will warp, bend, twist over time
Weather resistant Weather exposure will cause door to fail
One-piece construction Many pieces, each piece is a weak spot
High strength Moderate strength
Lightweight Heavy
Insulated No insulation
Highly customizable Choose from variety of designs
Affordable Handcrafted = expensive / import = cheap
Made in the USA Yes / No

sing-core-french-door-10-lightThe idea of building doors with a “sandwich panel” is not new. A sandwich panel consists, basically, of a core material (like a paper honeycomb material found in most inexpensive lightweight doors, or particleboard found inside less expensive heavy doors, while high-end doors may use expensive LVL or solid wood stave core but cannot be guaranteed true flat) sandwiched (glued) between two exterior surface materials – or “skins” – to form a composite panel suitable for creating a door.

Don’t be fooled by door companies who advertise that their doors contain “honeycomb core,” because they may be using paper honeycomb core which has little core value. Make sure you inquire as to whether your door has patented Sing Core, aluminum core or plastic core. Know what your core value is before you buy your door.

Patented Sing Door Core presents an entirely new set of advantages over other types of core materials that result in insulated doors that last for centuries due to the strength and lightweightness of Sing Core. See table of core comparision.

This new door manufacturing technology makes it possible to create the most versatile doors with a nearly unlimited range of design capabilities without the need of framing or antiquated stile and rail door building methods.

Sing Core could be the least expensive high strength, true flat core material ever invented.

Stile and rail and wood doors are labor intensive causing many of the door companies in the United States to seek off-shore solutions and import doors to reduce the price to the end consumer.

The invention of Sing Core is bringing custom door manufacturing and the jobs associated with it back to the USA. This is due in part to providing American door manufacturers with a base material (Sing Door Core) that enables them to build an insulated, high quality, lightweight, high strength door in any style, without labor intense stile and rail door building methods.

Doors made with Sing Door Core can be made to any size, easily be modified to simulate stile and rail multi-panel design, quickly and easily be custom cut for any size or shape of lite openings for glass placement, and can feature any exterior surface material. See photos.

Doors made of Sing Core shine across the door industry as metal doors, cement board doors, FRP doors and STC sound rated* doors while appearing is door applications as flush doors, French doors, sliding doors, pivot doors, bi-fold doors, entrance doors, interior doors, carriage doors, garage doors and barn doors. Even now, we are working with bullet proof door industry.

All this at a fraction of what it would cost in labor costs to build a stile and rail door made in the USA.

LESS ENERGY – LIGHTWEIGHT – HIGH STRENGTH – SUSTAINABLE

Composite materials, like Sing Core, are leading the wave of new advancements in material science that are taking these new technologies into the future. These revolutionary technologies focus on reduction of energy consumption both during the creation process and in material handling. The newest advancements address common issues associated with weight and strength. Other major concerns are in sustainability. Sing Core excels in all of these, while being extremely affordable and proudly Made n the USA.

Patented Sing True Raised Panel Doors

High quality Sing Core Doors are affordable compared with other types of stile and rail doors, raised panel doors, French doors, carriage doors, sliding door, etc…

A raised panel door gives you that classic look of a 3-dimensional door that becomes a focal point and statement by the designer and/or homeowner.

Traditional raised panel doors have been made the same way for hundreds of years, in recent years technology has been introduced to simulate this style at an affordable price. Price being a concern has led to more off-shore imports flooding the builders’ supply markets.

Case Study: 125-year-old New York Church

Church-Doors-Goshen-United-Methodist-Church-New-YorkIn this 125-year-old church project, the Sing True Raised Panel Door was the perfect solution to address the challenges.

Problem: Exterior wood stile and rail doors fail, bend, warp, twist; requiring continued maintenance and repair.

Solution: Sing True Raised Panel Doors, guaranteed true flat – and stay flat – in exterior application, while matching original 125-year-old raised panel design.

Details: Sing Core expertise in matching client’s specifications and requirements based on patented technology that can deliver true flat, lightweight and high strength doors in any size, that can be guaranteed true flat per your specific performance standards. In this case 6 weatherproof Sing True Raised Panel doors were required to replace 6 125-year-old exterior wood doors in an effort to eliminate regular maintenance and repair challenges of previous wood stile and rail doors.

Specifics: To address the issue of weatherproof and flatness integrity for centuries, the Sing design team’s solution included Sing Panels made of Sing Core door core reinforced with aluminum and a marine grade plywood exterior skin. To match the appearance of original traditional raised panel doors, additional wood trim was added atop the panels to match the 125-year-old previous door design. A perfect match with superior performance eliminating constant maintenance.

Note: The true flat weatherproof aluminum and marine plywood composite Sing Door is the solution for any exterior door of any size including large doors.

What is a Sing Raised Panel Door?

Sing Core introduces the True Raised Panel Door. The unique design of the Sing Core Raised Panel Door capture the original intent and look of a traditional raised panel door, but offers advantages that cannot be found otherwise.

Other raised panel doors offer little structural integrity. The structure can easily be compromised by little more than kicking the door causing it to break apart at the seams. In contrast, if you were to kick a Sing Core Raised Panel Door you would break your foot.

The secret is in the core of the Sing Core Raised Panel Door. The center of the door is solid as a rock, is resistant to warp, twist or rot and can be guaranteed true flat by build up the surface of Sing panel with molding and decorative raised panels instead the conventional raised panel doors are cave in at some area less than 1/2 inch thick, Sing and cost much less than a traditional raised panel door, which is not really a raised panel door at all in comparison to the Sing Core Raised Panel Door.

All doors start with the basic Sing Flush Door

wood-flush-door-lightweight-strength

The best solution according to the Sing Core culture and philosophy is the most affordable solution of using an authentic flush door, though many artists and designers use the Sing Core Flush Door as substrate and add moldings and decorations to meet varying aesthetic specifications.

Add molding for true raised panel features

6-panel-door-them6-Panel-Single-Door-UsSide by Side Comparison

On the left is the traditional 6 panel “raised panel door” and on the right is the Sing Raised Panel Door that is a true raised panel door, unlike the door to the left. Visually, they look identical, but that is an illusion.

The one on the left is made of 15 pieces of wood assembled together and where the routing is at its narrowest connection-points the door is extremely thin. While visually appealing with a classic look, the door on the left can easily be compromised by kicking the door at any given seam. On the other had an alternative approach is to carve the designs into a solid piece of wood (which is similarly weak at the deepest carve-points).

On the other hand, the Sing door blank is the base used as door substrate, now you can add molding and raised panels on top for the true raised panel door result. Warning: Kick the Sing Raised Panel Door and break your foot, not the door. (We accept no responsibility for injury.) If you can break a sing door, we’ll send you a new one for free.

Plus, the Sing Raised Panel Door gives you all the benefits that come with having an Eco-friendly technologically advanced door that simulates the classic style of the traditional raised panel door.

That’s why many designers who are restoring classic architecture are using Sing Core to replace outdated structural materials and doors. Working with Sing Core, artists and designers are able to duplicate the look and feel of classic materials without having to compromise by loss of energy or unreliableness of traditional building materials.
