19′ Pivot Entry Door



Interior view of extremely large pivot door with hardware


Case study:

A 55” wide x 19’ tall x 3.25” pivot door. With differing Cedar and oak wood stave skins.


Being approached by a client who is in need of a uniquely large pivot door to withstand the difficult climates of Lake Tahoe can seem like a near impossible feat. This pivot door needed to be lightweight for ease of installation and daily use by the client, impact resistant to hold up to everyday use, sound deadening to drown out the hustle and bustle of everything outside

A pivot door built with patented and patent-pending SingCore inside can make anything possible.

Opposing wood species

Dissimilar wood species on the interior and exterior of the door means differing rates of expansion and contraction. SingCore has the strength and stability to remain rigid against the push and pull of the dissimilar skins.


Lightweight oversize door


Now let’s take a look at why this door needs to be lightweight.

First off, big pivots doors tend to be very heavy which makes them more difficult to manage, they require custom made specialized hardware and require a lot of maintenance due to the stress that the pivot door adds to the structure.
Secondly a pivot door is only held with two points of contact on the top and bottom of the pivot door; meaning that if the door warps or twists, the door operation will be degraded or completely fail.

A pivot door this size with a solid core will weigh around 800lbs before any skins are added.
Now with SingCore, this door’s weight is a fraction of what other solid pivot doors would have weighed. This weight savings translates into a reduced overall budget by having lower shipping costs, lower hardware cost and lower cost for the labor of the installation.

Adverse climate for keeping oversize pivot doors straight

Ready for any climate
Lake Tahoe is known for its incredible skiing and breathtaking beauty. Not for its temperate climate.

This pivot door will see outside temperatures as low as 4°F while the inside temperature may be a toasty 76°F, which is a 72° difference.
SingCore pivot, sliding, hinge, and pocket door slabs are fully insulated with your choice of recycled EPS foam core (3.5 R value per inch) or urethane foam core (5.7 R value per inch).

Perfectly straight oversize pocket door

At 19’ tall this pivot door is as big of a challenge as it gets to keep straight.

All door slabs fabricated by SingCore are completely custom. The SingCore team takes into account the finishing, hardware, and climate when building each core. No two doors are alike. And we take great pains to ensure every pivot, sliding, pocket, and hinge door stays within AWI standards.

We love creating one of a kind oversize doors that no one else can.
