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
Lightweight
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
Straight
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.

The Sing home-building system started in 1992 as the founder /inventor Peter Sing patented his first vertical grain square log. There were already 24 patents under his name at that time. Since then, there have been a dozen more inventions related to home building products and methods and most are now in production as part of the Sing home-building system.
ENERGY EFFICIENT
ENVIROMENTALLY FRINEDLY
All the inventions of Mr. Sing are based on improving our life style with the least burden to our Mother Nature. These inventions pertain to energy efficient, sustainable, environmentally friendly, non-toxic, recyclable, longevity building materials. These are the prime emphasis of the Sing home-building system. Because of this, Sing home has been invited to build several full size homes in different home shows.
AWARDS AND ACCOLADES
Over the last 15 years Sing Home has proven itself to be among the strongest, most energy efficient and environmentally responsible of home-building systems.
In 2002 Sing home was honored to build the featured home in the San Francisco bay area, at the Peninsula Home Show.
Sing picture window structure frame has the highest insulation of any picture windows in history – R-28 instead of the conventional window frame of R-2 or less
Sing home building materialsfeature dimensionally stable vertical grain timber, which is –less twisting, checking and shrinking. It provides the greatest strength and utilizes the less natural wood fibers.
Sing Honeycomb is a sandwich panel composite material with built in structural grids. Our grids are made of vertical grain renewable veneer wood fiber, and foam. We construct our Singcore in a fashion similar to torsion box technology most commonly found in the airplane industry. This technology is what allows our panels remain strong, lightweight, and flat without denting, cracking, and warping. See a comparison here. Inventor Peter Sing uses this torsion box technology, along with wood fiber and foam to create patented Sing Honeycomb: the incredibly strong, true flat, lightweight, renewable composite material of the future. Check out our products section to see a few different applications.
Singcore Core Structure
The secret of the Sing Honeycomb panel is in the Singcore. Our Singcore utilizes torsion box sandwich core technology to ensure strength, and allow our product to be lightweight.
True Flat
Sing Honeycomb sandwich panels utilize torsion box strength technology in order to ensure flatness.
Vertical Grain Wood Fiber
The heart of soul of Sing Honeycomb is in our patented Singcore invention. The core utilizes renewable vertical grain wood fiber and foam, to create our strong, lightweight, composite material.
Strength
Sing Honeycomb is stronger than solid wood, plastic, metal, glass, brick, and concrete in terms of lbs. per lbs comparison.
Lightweight
Sing Honeycomb sandwich panels are strong, flat, and lightweight. A 4’ x 8’ x 1 ½” panel with 1/8 “ Luan skins, and solid wood edging weighs in at about 55 lbs. A standard sheet of plywood weighs in at about 96 lbs.
Rot Resistant
Even without coating, Sing Honeycomb sandwich panels outlast plywood, solid wood, MDF, and particle board. Plywood and engineered wood rot crack because of the weak glue layers. Sing Honeycomb panels last because underneath the skins lie Singcore, which keeps the panels flat through torsion box technology, and therefore doesn’t allow the panel to crack.

Standard sandwich panels utilize an insulating foam core sandwiched in between two thin sheets of hard material. However, this design offers very little strength and durability. Sandwich panels made by Sing Core are stronger, lighter, and more eco-friendly than these conventional panels because we replace the standard foam core with our patented vertical grain, natural veneer torsion box grid also known as the Sing Core. For the consumer, this translates into a higher quality product at a fraction of the cost.
Insulated doors made with traditional sandwich panels are highly susceptible to dents and structural damage because of their weak foam core. Doors made with our Sing Core sandwich panel technology can withstand much higher impacts resulting in little or no damage due to our unique core properties. The University of Washington has confirmed that our doors can withstand pressure of up to 660 psi, as compared to the average sandwich panel which can only withstand 60-100 psi.
If you desire products that are lightweight, strong, durable, dimensionally stable, and eco-friendly, then you must try our Sing Core Sandwich Panels. We like to demonstrate our confidence in the integrity of our products by offering our customers a 10 year structural guarantee.
The simplest and least expensive way to join sing panels is to join in any way according to your budget and/or expertise.
Due to Sing Panels being so straight and true it is easier to join panels together because they line up perfectly unlike other building materials.
In many cases, for instance, standard 4×8 panels can be nailed, glued or channel-joined quickly and easily with satisfactory results.
Other options for fastening panels may include cam locks (see examples left and right) that can be pre-installed, making assembly and joining easy and more secure.
The Sing cam-lock panel solution is a high-demand solution for panels that are routinely assembled and disassembled, especially in moveable walls, trade show booths, and various wall cladding applications. See: Cam Lock Panels

Thru-bolt Joining
One of the most inexpensive and secure ways to join sing panels is by utilizing a simple nut and bolt connection method, especially, if the panels will be routinely or repeatedly assembled and disassembled.
Stainless steel nuts and bolts offer the safety and security when joining sing panels.
Biscuit Joining
In many cases, Sing Panels can be pre-configured for biscuit joining at your site of factory.
Especially for large projects, this enables Sing Core panels to be sent individually, reducing shipping and handling costs, for assembly at your facility or job site.
See images below for example of biscuit assembly of Sing Panels
Unless specified Sing Panels do not ship edge-banded as 93% of our wholesale customers do their own edge-banding when finishing their Sing Panel.
Edge banding can take many forms from vinyl and plastic to wood and steel. Sing Panels are not intended for use as an un-banded product and may not qualify for our 50 year warranty if un-banded.
If your intention is to get the best, most long-lasting performance from your Sing Panels, feel free to take advantage of our free consultation to be guaranteed to achieve the results that you desire.

Advanced Large Panels
Sing Core specializes in extremely large panels (up to 50 feet) that are extremely true flat and use our nearly seamless assembly process.
This is the most high-end and expensive process where we perform the highly specialized meticulous work in our factory yielding the high level of perfection that many of our most discerning clients require. See: our clients.
These must be manufactured in our plant to ensure accuracy with tolerances within thousandths of an inch and are more costly to ship due to the nature of their being larger than multiple panels that can be assembled on-site.
Connectors for Connecting
Cam-Locks
One of our many features is the ability to add fasteners/locks to our panels…one example of this is the “S-Hook Lock” with a turn of the hex wrench you can fasten or unfasten your panels quickly.
The “S-Hook” fastening lock that is attached to the side of these panels to allow for easy assembly of the wall system.
With a quick turn of your wrist on the hex key your panels will be attached to each other.
Barn Door Assembly or ‘H’ Channel
If you are planning to keep your panels as a permanent structure you may choose the H-Channel attachment feature. Apply your adhesive the slide panel into the channel on each side then either veneer over the panel and channel or you may choose to putty, sand and paint your panels to cover over the H-channel.
Tongue and Groove
Tongue and groove is another fastening choice especially if you using our panels for flooring or ceiling. Make a nice almost seamless connection but give wood veneer a hardwood flooring appearance.
Biscuit Joint
This is a modified biscuit joint attachment. Similar to the H-joint the you are using a single long “beam” as the connector and gluing them together. Best use is for oversize tables (such as vacuum tables) and oversize doors as well. Because our panels are made of honeycomb rather than solid wood, they will not warp. Our honeycomb is light and strong.
Ship Lap
The ever popular ship lap as a connector alternative.
