Designer 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.

Look Like Solid Wood

With our new solid edge/veneer face treatment, we can make any door appear to be a full solid wood pivot door, just like the pivot doors atop World Trade Center One. Here’s a closeup:

Pivot Door Swing

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

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.
