Sliding doors at Laserfiche’s New Headquarters
Sing Core is honored to be part of making an innovative workspace for Laserfiche in Long Beach, CA.
RDC of Long Beach California designed these doors to work seamlessly with this interior workspace. Following the design of RMC, Seeley Brothers Millwork of Brea California used four custom made Sing Core panels to complete this project for Laserfiche.
These Sing Core sliding doors are used to allow these workspaces to feel like one larger room and a second later be a quiet and private meeting space. Sing Core doors naturally dampen noise of an active workspace to easily allow other employees to concentrate and be more productive. These were some of the core ideas that Laserfiche had when building their new Headquarters.
These elegant lightweight doors are extremely strong and durable. They are made of the highest quality material suitable for any museum, mansion or workspace.
As you can see these doors have to be completely straight to allow a perfectly matched seam when they are closed.
“They are the most exciting sliding doors I have ever seen” -Peter Sing, Sing Core inventor.
Simple to design, simple to order. See the shop drawings here.

We’d like to thank everyone that came together to make these magnificent doors come to fruition: Studio One Eleven, RDC Architects, Millie and Severson Contractor, Seeley Brothers Millwork and of course Laserfiche for wanting to improve their employee’s wellbeing with this innovated design.
Laserfiche is a leading global prover of business process and information management software. They have been part of the Long Beach community since 2001. They were founded over 45 years ago and also have offices in Washington DC, Guadalajara, Hong Kong, London, Shanghai and Toronto. 320 of the 425 employees are in the Long Beach area and they are steadily growing.
Their new headquarters was completed in May of 2022. It is over 100,000 square feet, with four floors and a parking garage. It can accommodate 550 full-time employees working in-office and up to 750 hybrid workers. Studio One Eleven’s design mirrors a landmark garden-office building across the street designed by the late Mid-Century architect Edward Killingsworth. They incorporated such Mid-Century Modern elements as large windows and terrace decks that provide amble natural lighting. The height is the same as the adjacent building allowing to blend in seamlessly. Chris Wacker, chief executive of Laserfiche, Wacker called the space “extremely functional and useful in a hybrid environment.”
The design layout shifted the service core to the western edge of the building, typically in the center. This allows a larger continuous communal and workspace environment. This also blocks the western solar heat. Now the elevator is tucked away and the stairs are front and center, promoting the healthier option of taking the stairs.
Laserfiche was committed to staying in the Long Beach area and are in the Bixby Knolls neighborhood. Here on Long Beach Boulevard near the San Diego Freeway, their Mid-Century landmark makes a bold statement to the half a million daily drivers who pass by. Before Laserfiche purchased this land, it was considered an unusable wasteland left over from oil extraction years. They capped off the old oil wells and removed the old hazardous tanks.
According to Chris Wacker, Laserfiche CEO, “We have abandoned the traditional vertical office building paradigm, emblematic of individual aspiration, for a horizontal environment where connections are fostered and relationships built and we’ve implemented ideas from our products into the design of the building we know that process automation makes life easier. It removes the bottlenecks and impediments to fluid operations, promotes efficiency and allows organization to thrive. This building’s open design does the same thing. It enhances the free-flowing information making our lives simpler and more creative.”
“This building is the future of work. People sharing spaces in the ways most productive for them. As we learned over the past two years, that makes the most productive for the company and the people that use our products. Just as Laserfiche is dedicated to helping people turn their data into digital assets, this building helps Laserfiche maximize the potential of its people. Laserfiche digital transformation increases your people power by eliminating the unproductive and focusing on the creative, and that’s what this building does. It’s a hybrid workspace for a hybrid workforce.”

The Garage Door Solution
Sing Core Garage Doors
The most common problem for garage doors is the continuous exposure to the outdoor elements. Which subjects one side of the door to daily changes in temperature while the other side sees a constant interior temperature. This is where a solid wood garage door would fail and crack due to the wood expanding and contracting inside the door. This is a major flaw which requires frequent maintenance, such as repainting and resealing to prevent water damage.
Now with a Sing Core door, a garage door can have any skin from metal to old growth Douglas-fir.
Aluminum and metal skinned
Aluminum is a great option for sliding barn doors. The aluminum produces a lightweight and strong finished product. To seal metal and aluminum doors from the elements we have discovered the perfect solution, vinyl wrap.
Vinyl Wrap
Vinyl wrap will adhere to any door’s surface. The glue will seal out any moisture. The vinyl is fully customizable to any design of your liking and will provide full UV protection of your door. Learn how to build a true flat long lasting carriage door here.
Wood Skinned
The best choice for a wood garage door is AB plywood or marine plywood. There’s no need to worry about the plywood cracking with the inclusion of proper finishing when using Sing Core thanks to our patented and patent-pending torsion box “honeycomb” design. This is why they are used on our Sing Core homes.
Wood Stave
A superior addition to any door is to add wood stave to the face. Our most common wood stave products are clear cedar and douglas fir. With wood stave applied, the door looks like it’s made of solid wood.
Unlike a thin .020 wood veneer; wood stave can be sanded and repaired if damaged. Making wood stave a more durable solution to high traffic areas or commercial applications.
Does your customer need a rugged wood stave skin or a thin veneer? Ask one of our knowledgeable sales engineers about the pros and cons of different skin options and they would be happy to walk you through your options.
1/8″ wood stave is all that is necessary to make your door look like it is made completely out of solid wood. But the secret inside is that your door is exponentially stronger and more stable than a standard solid wood door. Your Sing Core door is also almost a third of the weight of a comparably sized solid wood door. Being lightweight expands the choices of hardware, reduces labor costs to install, and is safer in inclimate weather. This applies to all doors with Sing Core inside; pivot doors, sliding doors, pocket doors, carriage doors, bi fold doors, and other doors with unique hardware configurations. Learn more about wood stave here.
We have a very large inventory of wood stave in stock. We will sell the wood stave by the square foot and have a wholesale option. Wholesalers are eligible for discounted pricing on wood stave lots. Contact our sales team for details about wood stave lots here.
Below are a few of the other examples of garage/barn doors we make.
19′ Pivot Entry Door
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
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.
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).
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.

How Does the Sing OEM Process Work?
Establishing the Need of Sing Core
There are many reasons that door manufacturers seek out patented Sing Core as their OEM door substrate; some of the most popular ones are:
Creating a Superior Door Line
Some door manufacturers are looking for ways to distinguish themselves from other door manufacturers. They seek out an OEM relationship with Sing Core to design and build an ultra premium line of doors that have unique characteristics that cannot be found by using any other door substrate material.
BIG Door
Many door manufacturers have problems with large doors (especially over 7 ft. tall) in that while they look magnificent upon installation, dealing with door warp on a regular basis is a constant maintenance cost associated with big doors.
This is where Sing Core door substrates shine because the substructure of the core itself is a combination of wood torsion box (using vertical grain matrix framing) filled with recycled rigid foam creates a lightweight, high strength solid substrate that will retain its original shape and structural integrity over time; higher precision and lasts longer than any other known door building material.
That’s why more and more, you are finding Sing Core™ inside some of the biggest aircraft hangar doors, large sliding barn doors, factory doors, large commercial doors, warehouse doors and large garage doors.
Non-warp Door
Sing Core™ is the only door core material that enables our door manufacturers to deliver doors that do not warp regardless of size or external materials in either interior and/or exterior doors, if they are designed by our Non-warp True Flat Specialists. Sing Non-warping door blanks are available in any type, style, shape, exterior skin and/or composite configuration.
Insulated Door
Insulated doors offer enhanced separation between two areas separated by an opening, doorway or egress point. Sing Core insulation starts at R3.5 per inch and goes up from there, based on architectural specifications. Insulated door are of primary interest to architects, designers and engineers seeking soundproof door, hurricane doors* or other weatherproof door where an insulated door is specified.
Security Doors
Sing Core is of primary importance in security doors of substantial size. Large security doors are difficult to manage normally due to weight; this problem can be solved with the Sing solution. A security door can be used in a variety of circumstances and applications including impact doors, and bulletproof doors.
Using Sing Core™ inside, impact resistant doors don’t have to be heavy weight, which causes unnecessary stress and strain on both the hardware and structure, while delivering all the security desired including increased privacy due to innate door insulation.
Specialty Doors
Sometimes a custom door manufacturer, millwork or door manufacturer faces a job that requires doors with unique attributes to accommodate a particular usage following installation.
Specialty doors may need particular characteristics to meet the requirements of the end user. Architects, designers and engineers can use Eco-friendly Sing Core™ inside to have greater control over:
Weight
Strength
Insulation
StructureNon-warping
Sound deadening
Impact resistance
WaterproofAny size
Any style

High Precision Doors
Sing High Precision Doors are a marked improvement in door development, design and implementation thanks to a newly invented Eco-friendly core material that is lightweight, insulated and stronger than steel pound for pound.
This new technology is revolutionizing the door industry especially in regards to large oversize doors. Architects, designers, mill works and door manufacturers all experience problems with doors that are larger than normal size.
Large doors present a variety of challenges in areas, like:
- choice of available materials
- lightweight doors are weak and tend to fail
- heavy doors strain hardware and structure
- increased regular maintenance
- failure due to warping
Sing High Precision Doors solve all these issues with an Eco-friendly insulated solution.
How high precision are Sing High Precision Doors?
Sing High Precision doors are created with so much accuracy that the original door slabs are perfectly flat within .0006 inch accuracy.
After applying your desired composite materials and/or skin, your high precision door can be laser CNC machined for a perfectly flat surface, limited only by the accuracy of your CNC machine shop capabilities.
The Large Challenge
Certainly, you could use laser CNC cutting and engraving to machine nearly any door made of almost any commonly used door material for a flat result. The challenge comes from standing the door upright and expecting a degree of effective usefulness over time.
The effects of gravity, varying degrees of moisture and/or atmospheric change, and the natural limitations of the characteristics of the building materials that comprise the door all contribute to its failure. This causes dissatisfaction for the end user, who has invested a great deal of expense in the design, manufacture and installation of this specialty large door.
Door warping is the number one problem for oversized doors that are otherwise enjoyed by the most discriminating end users.
The Disappointment
No one wants to spend that kind of money on a door that is going to warp, bend, twist, delaminate or compromise the structure or hardware with normal recommended use.
Now, here’s the exciting part…
Sing High Precision Doors can be guaranteed not to warp, bend twist or otherwise fail for 50 years!
Imagine having a large door that can be installed that will not pave the way for repeated service calls over the life of the door.
Take a look at some of our clients who trust us with those difficult door challenges because they are the most reputable high performers in the industry who only deliver the highest marks in terms of customer satisfaction, especially now that they can deliver a fail-free large door that will not cause frustration for their client’s or their service departments. See clients List.
Highest Precision in Doors
No other building material can be guaranteed to maintain a true flat surface and milled with laser precision for long-term maintenance-free performance for 50 years. This is why you can find the growing demand for the Sing solution from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.
The high precision Sing solution is not just for doors; turned flat these very same Sing Panels can become floors, tables, counter tops, ceilings and roofs. Turned on their sides, these patented panels become walls, moveable partitions or virtually any other type of application.
800 Square Foot Buildings No Permit Required
We are so excited to see municipalities and counties all over the nation are beginning to loosen the grip on residents who desire to build their own projects on their own properties.
Sing Core’s national headquarters is located in McCleary, Washington and we’re proud to live in Grays Harbor County that has recently embraced lightening the restrictions on property owners to build their own 800 sq. ft. structures without a permit. Many areas are joining the revolution to allow residents to build structures independently.
An 800 square foot structure is a reasonably-sized structure that could offer a comfortable living environment, like a tiny house.
Let your local government know about the trend of NO building permit required for 800 sq ft building.
Change your county building code if this is not available for you.
For instance your 800 square foot structure could have a 20 ft x 40 ft footprint, like this one:
This 10 foot tall walled structure could be built using 5 ft x 20 ft galvanized steel panels with door and window cutouts in less than an hour by a few people (using a rapid assembly method). Seem like too little time? Okay, add a second story in another hour, even a third story.
Building a two-story house in two hours using two people could only be possible using patented Sing Core technology.
Check local building codes in your area. Most counties or municipalities allow the do-it-yourself builder to construct a structure of a minimal size without a building permit. Other options (as recognized by many tiny house enthusiasts) include building your structure on a trailer; as mobile structures – like a tiny house on wheels – are exempt from building codes.
Don’t Be Framed
Building structures with Sing Panels does not require traditional framing because the structure is built into the wall. You can build a solid structure with 1 inch thick wall panels without any structure framing due to Sing Core’s:
High Strength
Patented Sing Core provides a natural vertical wood grain torsion box/foam composite that is so strong that it is recognized by high-tech industries as the strongest affordable lightweight building material that is stronger than steel pound for pound and able to reach long spans without heavy substructures.
Building with this patented technology is advantageous for so many reasons, like:
Lightweight
Sing Panels are easy to handle because they weigh so much less than other building materials. One person can easily handle a standard 4×8, and two can easily maneuver a 5×20 – not because of the weight – due to the awkward size.
Rapid Assembly
There are so many options in methods of assembling your Sing Panels in your building project, but there are extremely fast options. For instance, you could have your Sing Panels pre-cut for all window and door openings and have quick connecting cam-locks installed for quick and solid assembly. See Video of a 70 ft trade show display erected single handedly in less than 1 hour.
Insulation
Every Sing Panel is packed wall-to-wall with insulation and can achieve R-values of 6.5 per sq. inch. There’s no need to insulate your pre-insulated wall panels; plus you get the added benefit of extra privacy and protection from the environment due to inherit sound-deadening qualities.
Save on Construction Costs
Save up to $5000 – or more – just on construction costs due to being lightweight, easy to assemble and not having to require time-consuming 2×4 framing. Your contractor can save both time and money. No need to frame, plus you can have all door and window openings pre-cut and ready to build.
Weather Resistance
Your reinforced structured insulated panels can be pre-fabricated using any extreme-weather resistant exterior material you desire. Most popular for rapid pre-fabricated structure building includes fiberglass, marine-grade ply and galvanized steel, which offer weather resistance without applying additional siding.
High Performance
Long recognized for inventing the only high-precision true flat building material that stays flat, your Sing structure will remains straight and true, not like wood framing and other materials. Only sing Panels can affordably achieve these high marks.
Versatility
Sing Panels are available in nearly any flat exterior building material including, but not limited to, any wood species, aluminum, concrete, FRP, HPL, Kevlar, metal, plastic, stainless steel, etc… Just about anything you could desire. Plus, you could have one material on the inside facing, and another on the outside. Example, galvanized steel on outside and plywood on the inside.
Customize
We’re all about helping to make your design dreams come true. We can modify Sing components to your specifications and meet the structural durability requirements of your project. As we are well-known world-wide for building large oversize doors that can be guaranteed for 50 years and will not warp, bend, twist or rot using this technology; this is our specialty.
