Sing Core at the Auburn Gresham Healthy Lifestyle Building

The Greater Auburn-Gresham Development Corporation is leading an effort to redevelop a vacant office building on a key commercial corridor in the Greater Auburn Gresham community. The redevelopment of 839-45 West 79th Street is a development project that will not only urge additional development along the disinvested business district, but will also bring back to life a once prominent commercial building that has stood vacant for twenty years.



The redevelopment project is being implemented as part of the recently completed Auburn Gresham Quality of Life plan which has several strategies and tasks to improve the quality of life of residents in Auburn Gresham and surrounding communities. During the 1 1/2 year long planning process, more than one-thousand residents were engaged and took part in monthly discussions and together, divided into separate issue area task force teams. The task force teams focused on core areas including: jobs, economic and business development, health and wellness, education, youth development, and more. When complete, the redevelopment of the vacant building into the Auburn Gresham Healthy LifeStyle Technology Hub directly responds to the community’s quality of life plan including workforce development, technology and educational enhancements, along with community development services supporting youth, seniors, families and disenfranchised serving the greater south side.

Sing Core was able to be part of this wonderful project by providing our Pocket Doors. These doors are a type of sliding door that recesses into the wall instead of sliding in front of it, effectively becoming invisible. We make these doors possible with our lightweight and sturdy core.

Pocket Doors

Secret doors are an exciting and distinctive way to add uniqueness to your home. Pocket doors have become an integral part of modern architecture. The can be more than just a convenient sub-type of sliding doors. Pocket doors are one of the only options when considering a concealed or hidden door.
Pocket doors provide a special twist to any sliding door application. Pocket doors largely improve the area near the door opening, as a traditional sliding door requires dedicated wall space to open over. Pocket doors fully recess inside of the wall, meaning all of the necessary holding space is in a place you already couldn’t make use of. Pocket doors also prove to be useful in space-saving scenarios, such as in an RV or small office.


Well-known to outperform any other known honeycomb core or composite honeycomb material, Sing Core has been rated at 660+ PSI and has the highest tolerances for high precision integrity over the surface of the material.

In side-by-side comparisons, patented Sing Core outperforms all other honeycomb core materials in terms of an Eco-friendly high performance material that is insulated, stronger and lighter weight. The added insulation provides both R-value ratings and sound deadening that are not available in other honeycomb cores.

That is why our most high end clients, including the scientific community, aerospace industry, nautical industry, industrial, space and military agencies rely on Sing Core for the most high precision and high performance core material available.




Sing Core Pocket Doors, like all Sing Core products, come with a 50 year structural and warp-free guarantee. You won’t find this common in the industry, as few products can hold up to it. At Sing Core, we don’t make empty promises. Your door will last for 50 years without structural or warping issues, guaranteed.

Guarantees are offered with doors which are covered, in writing, signed by the inventor of Sing Core. We take our 50-year guarantee very seriously. Our best clients depend on this worry-free performance and trust us to provide them with the best solution for large doors of any size or style.

Millennium Tower Seattle

The Millennium Tower

The skyline of Seattle is adorned with beautiful spires and towers, and the Millennium Tower is one of the structures to call that sky home. Standing at over 280 feet tall, the Millennium Tower is a testament to luxury and design, as it is home to 19 prestigious condos and sits right off the water in Downtown Seattle.

The Millennium Tower was designed by the Olson Kundig architect firm, and the individual homes within were designed by the architects from Zimmer Gunsul Frasca Partnership. This brilliant combination of efforts has led to one of the most incredible living spaces in the Seattle area, and Sing Core is honored to have been involved in this project.

Sing Core was contacted regarding a large pocket door for the interior of the tower, specifically within one of the condos, measuring 54.5 tall inches by 111.5 inches wide, and 2.25 inches thick. This door weighs approximately 200 pounds, which is substantially less than a door of this size would if made using traditional methods and materials.

Why Sing Core?

Sing Core has long been sought after for use in high end and luxury homes, penthouses, and more. Our patented and patent-pending technologies allow us to create the highest quality lightweight door and wall panels, without compromising on strength or durability. Our panels can be made to nearly any size and specification, and are pound-for-pound stronger than steel. These features, along with the many other benefits of Sing Core, are what led the design teams to utilize our product.

Another large reason the company decided to go with Sing Core was in regards to the type of door they were wanting. Our panel was used to make a large pocket door, which are notoriously difficult. First, pocket doors are a variant of sliding doors that slide into a “pocket” within a wall instead of sliding in front of the wall itself. These doors must be perfectly straight, otherwise they will not fit within the tight space in the wall. Pocket doors are also severely limited on their weight, as a heavy pocket door can prove difficult to use and damaging for the hardware.

Another major complication with pocket doors, especially of this size, is the risk of warping. A warped door is never good, and often leads to total structure failure and replacement. The larger the door, however, the more likely it is to warp due to the increased tension on the surface. Plus, with pocket doors, even the slightest warp can ruin the door and stop it from functioning. A little bend can cause the rollers to jam or break, or if the warp is significant enough, it can start to scrape along the wall inside, or get stuck in the pocket entirely. Luckily, Sing Core doors never warp, and are guaranteed to not warp or fail for 50 Years.

A Successful Project

Despite all of this, an excellent design, a skilled construction crew, and a flawless Sing Core panel led to a gorgeous condo within this incredible building. Unique projects such as these are what allow the luxury design world to thrive, and Sing Core is proud to have been involved in something that is such a testament to this industry.

Sing Core Pocket Doors (Hidden Doors)

What is a Pocket Door?

Pocket doors are a type of sliding door that slides into a pocket in the wall instead of in front of or behind it. A variant of the pocket door is a “hidden door”, named that due to their hidden nature and the ability to create a nearly invisible door when closed.

Pocket Doors

Pocket doors are popular for many reasons, one of which is their space saving nature. Traditional sliding doors require the nearby space along the wall to remain empty so that they can open and move into that area. Pocket doors, however, are built to slide directly into the wall, and as such allow you to put furniture, decorations, or anything else along the walls nearby.

Pocket doors often require more engineering to make work, as they need a finished pocket with suitable space inside the nearby wall. This does present a potential hurdle in the construction of your door, however if you plan on doing this before starting construction, it is easy to work into the plans. Also, you can have a pocket door installed in a pre-existing wall assuming the wall is thick enough to allow for it, or you have the means of altering said wall.

Pocket doors are a fun and creative way to provide access to a room, and also tend to last longer than traditional sliding doors seeing as, when opened, they are not exposed to traffic or the elements. If you’re considering the options for a new door in your home or office, consider a pocket door for a unique and fun result!

Hidden Doors

One popular style of pocket doors are hidden doors, which function the same way, but have some added features to make them practically invisible. Hidden doors are usually designed to blend into the wall around them, providing a near-seamless exterior and, thus, proving incredibly difficult to spot, even if you’re walking right by it. Hidden doors work very similarly to pocket doors, using rails to slide into a hidden space within the nearby wall. Where they differ is that hidden doors often have an additional mechanism to press them up to be flush with the nearby wall, adding to their hidden nature.

Where Sing Core Comes In

Sing Core advanced panels can be used to build sliding doors of any style, including pocket and hidden doors. Our panels are super strong and lightweight, so you get assurance that they can hold up to use, plus their lightweight nature extends the life of the hardware, and as such the door, by a significant amount. Our panels also have a 50-Year Warp Free Guarantee, meaning your door will never warp or twist and become unusable. Many doors risk warping due to their flat and incredibly precise nature, and even the slightest of warps can completely ruin a door’s appearance and functionality. With Sing Core, you never have to worry about your door warping, and we give you 50 years of promise to prove that.

Interior Pocket Doors

Need to make a small room seem bigger? Tired of the footprint taken up by the door swing? A pocket door could be the perfect solution to these issues. Pocket doors have their origins in Victorian homes where they often separated formal seating areas or entry ways. A pocket door is a type of sliding door. Unlike a regular door, a pocket door slides in and out of a wall on a track. Sliding Pocket Doors are a great way to conserve space. Similar to sliding barn doors, pocket doors have the ability to be hidden within a wall. Pocket doors are the perfect portal for powder rooms, laundry rooms, pantries or utility rooms. In small areas like these, a standard swinging door would take up a significant amount of space.

What is a pocket door and how does it differ from a regular door? A pocket door is a type of sliding door. A pocket door slides into a hollow cavity, or “pocket,” in the wall.

Pocket doors maximize under-utilized areas around doorways and transform them into smart storage spots. A pocket door simply slides into a frame in the wall, freeing up a great deal more of the room and opening up the design possibilities.

Sliding pocket doors were very popular with turn of the nineteenth century builders and they can be seen in different style and design such as double pocket door. An open interior door breaks up the line of the wall and can look a little clunky.

Pocket doors disappear completely when open, creating an elegant, streamlined appearance. Sliding pocket doors are useful in designing two separate rooms, so that they may be joined as needed. Pocket doors don’t seal a room as tightly as a traditional swinging door, and the typical locking mechanism is flimsier than a tubular latch or deadbolt.

This is why sliding pocket doors are best used as interior doors. Pocket doors are an interesting addition to many homes because they slide into the wall, hiding the door when open. Most of you already probably know this, but for those who don’t, pocket doors are interior doors that “disappear” into a shallow slot inside a wall.

When it comes to saving space, pocket doors are loved by designers, builders and homeowners alike. A pocket door is a great way to pick up usable space that’s normally occupied by a swinging door. Sing Core creates sliding doors and pocket doors for stylish, intuitive, and space-saving solutions.

These pocket door frames are made of sturdy wood, with a skin of your choice. We can provide veneer, wood stave, aluminum, hot or cold rolled steel, and much more!

Here at Sing Core we specialize in custom doors, so if you can think of it, then we can do it! Let us help you with your next project. Sing Core produces the most accurate door panels on the market.

Sing Core is the only company to produce over-sized doors that are structurally guaranteed for 50 years. No other door company can structurally guarantee their doors for 50 years, even their standard sized doors.

Wood Pocket Doors

Wood pocket doors are similar to wood sliding doors in that they use similar sliding door hardware only a sliding pocket door disappears as it vanishes into an adjoining cavity within a wall (a pocket) and is therefore invisible when in the opened position.


Even though most wood pocket doors are interior pocket doors and not exposed to the weather, they do tend to warp due to changes in the environment which may render wood pocket doors useless and inoperable as they are not freely sliding in and out of the pocket for which they were designed.

By definition, sliding pocket doors should smoothly glide in and out of the cavity provided for storing or hiding them when not in use. Signs of malfunctioning wood pocket door would include not freely gliding, sticking, rubbing against the frame (damaging the finish), or getting stuck altogether either inside or outside the pocket.

The AIA and industry standards in the pocket door hardware manufacturers channel allow for a certain degree of warping to accommodate a wood pocket door’s potential to move according to changes in the environment. For instance, a 3-0 7-0 wood pocket door is considered straight and not warped, if it has a 1/4-inch variance in it. Anything over 1/4-inch is considered a warped pocket door.

That is to say that your pocket door contractor, builder, installer, and the hardware provider have taken all of this in account, and everything is built to accommodate this quarter-inch variance. These would not be considered high precision wood pocket sliding doors.

If you want high precision wood pocket doors, there is hope for you thanks to new patent and patent pending pocket door building technologies introduced by inventor and founder of Sing Core, the revolutionary Eco-friendly lightweight, high strength, pocket door building material that enables the biggest door manufacturers and best millworks in the world to create pocket doors of any style, shape, or size that can be

Guaranteed Warp-free for 50 Years

The only way to build an Eco-friendly, lightweight, high strength wood pocket door that can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years, is if it has Sing Core inside. In fact, the biggest door companies in the world know this, and are already doing it, thanks to Sing’s core.

Wood Pocket Door Problems

It’s all about overcoming all the various challenges associated with wood pocket doors, especially if they are large oversized wood pocket doors.

We’ve already determined that keeping your pocket doors straight and true is a huge concern. In the past, the insertion of heavy material, such as a steel frame, could be built into the door to help keep it straight, or it has been assumed that heaviness was associated with strength.

Not he case with Sing’s core, which is both lightweight and stronger than steel pound for pound (independently tested at 660+ PSI). Next up you have the relatively low precision of other heavier materials, and the more you work with them the more compromised the precision is. Not so with Sing Core.

Sing Core is one of the highest precision lightweight high strength building materials in the world, sporting .006 in. tolerances.

This is how to make high precision wood pocket doors.

This is the perfect way to approach a double pocket door project, which, as you may have guessed, could present twice as many potential problems as a single prehung pocket door.

As you can see, Sing Core is an integral part of high-end pocket door construction and now you know how to build the best pocket door in the world.

Keep in mind that while Sing Core helps to build the best sliding pocket doors which provide added safety, security, privacy and superior function, your classic custom pocket door project would not be complete without utilizing an entire team to yield the best results.

High-end pocket doors are used for architectural effect, and to pull off the kinds of results exemplified by the best wood pocket doors with Sing Core inside, you will need to have the other artisans in place as well.

10×12 ft 3″ thick warp-free 1/8″ oak 520 lbs

Sing Core does not actually make doors. What they do is to provide the biggest door companies in the world, the finest millworks, and top manufacturers of custom wood pocket doors with the best patented lightweight, high strength, fully insulated, and warp-free base doors which are used to create the one of a kind masterpieces that Sing Core is known for.

“We could not do it alone,”

says inventor, Peter Sing, whose factory only supplies the basics to others who turn his substrate into art. And likewise, the door companies, millworks, and custom wood pocket door manufacturers admit,

“We could not do it without Sing Core.”

Because there’s no other way to build a fully sustainable lightweight, insulated, and warp-free wood pocket door, unless it has Sing Core inside.

Large Pocket Doors

For years, large pocket doors were not being installed in new builds due to problems associated with pocket doors which exceeded the normal range of door sizes. The biggest concern with these big pocket doors was their tendency to twist or cup according to the season.

If you haven’t experienced such challenges, it doesn’t take too much stretch of one’s imagination to entertain how frustrating it would be to open or close your large pocket door only to find it had seized up either inside or outside of its pocket housing.

Pocket doors are a magnificent way to cordon off an area or open up two adjoining spaces quickly and easily, and if your sliding pocket doors operate as expected, it’s an elegant sight to behold as the sliding doors smoothly disappear into their wall cavities. This is why they are sometimes referred to as a hidden pocket door or concealed sliding door. No swinging into the room so as to disrupt the area or require clearance for opening and closing, and not to be seen in the open position, as if they were never there in the first place.

Thanks to inventor Peter Sing, large pocket doors are coming back into new builds and remodels because he has provided the door industry with the warp-free technology required to create warp-free large pocket doors which can be guaranteed not to warp, bend, twist, cup, or otherwise fail, for 50 years.


Large Sliding Door Strong Straight Warp Free

Sing’s core, which he calls, “Sing Core,” enables pocket door manufacturers to create large pocket doors of immense size built of any material, measuring up to 50 ft or more, and still be guaranteed to offer fail-free service for 50 years.

Sing’s Eco-friendly patented and patent-pending warp-free technologies enable his factory to create non-warping substrates which are high precision (+/- .006 in.), fully insulated (R3.5 or R6.5) for sound dampening and climate control, lightweight (1/3 or less the weight of other wood-based solid core large pocket door blanks), high strength (660+ PSI, stronger than steel pound for pound), and backed by Sing’s unprecedented 50-year guarantee.

All that reduction in weight and increased strength, precision, and insulation changes the whole dynamics of a sliding door inside wall which would otherwise be problematic, so you don’t have to worry about your pocket sliding door that goes into a wall which may never come out. You can rest assured that your sliding doors into wall cavity will serve your safely, securely, and reliably over their 50-year guaranteed service life.

If you really want to upgrade your efficiency and the impact garnered by operating your precision large pocket doors, install a double pocket door. That’s right, two separate large double sliding pocket doors side by side, each sliding doors into wall cavity respectively independently or in unison. Make them full floor to ceiling large dual pocket doors for full effect.

Joining Large Sliding Pocket and Pivot Doors-Animated

Using Sing’s technology, you won’t have to worry about shelling out the big bucks for heavy duty large pocket door hardware because the hardware rating required to operate your door efficiently is based on the weight of your pocket door. Large pocket doors with Sing’s core inside weigh far less, enabling designers and installer to use less expensive pocket door hardware reducing the overall pocket door price.

Heavy duty pocket door track is unnecessary, as are expensive pocket door rollers, or other heavy-duty hardware or equipment. Sing’s lighter in weight large pocket doors are much easier to transport, manhandle, move about the job site, and install resulting in savings in pocket door cost all the way around.

Now you can have a heavy-duty impact resistant large pocket door that is lightweight and high strength without all the added expense and regular maintenance of any other type of heavy duty pocket door.

DIY Pocket Door

Okay, since you asked, “Can I create a DIY version of a large pocket door with Sing Core inside?” The answer is (with respect to Sing’s patents), you could create your own wood pocket door in do it yourself fashion using Sing’s ideas.

You will need some carpentry skills, woodworking tools, and a shop if you’re thinking about adding a pocket door to your DIY list of projects. If you’re ready, you’ll need a perfectly flat work surface a little larger than the size of your proposed custom pocket doors. You will also need a DIY cold press system, which could include lots of clamps or a vacuum bag lamination system.

First, you will need to build the torsion box grid substructure. You can find directions online using Google how to build a torsion box grid, but note that unlike the instructions you will find, Sing using vertical grain orientation in the wood fiber used for the torsion box, not horizontal, for added shear strength.

Sing also knows the small the individual cells of the torsion box, the more strength, so his cells vary depending on the application from 2×2, 2×3, or 3×3-inch cells.

Build your torsion box inside a wood frame and insert any necessary hardpoints (wood blocking for door hardware). After you’ve completed the torsion box in the desired size, glue rigid foam (Sing uses recycled EPS foam as his default in the factory, but clients may specify other materials) inside the empty spaces inside the otherwise empty torsion box centers, and let dry.

Precision sand this reinforced wood fiber/foam core to the exact desired thickness.

Now you have a dimensionally stable lightweight core which needs to be sandwiched between two stress skins (say quarter-inch plywood) and this is cold-pressed and left to cure.

You’re on your way to building a pocket door by laminating your desired wood surface material and any edge trim you may want as you’re getting ready to be adding pocket door to existing wall(s) in your project location (home, office, etc.).

This should be suitable for making a pocket door which is lightweight, high strength and will work for any 8 foot pocket door or less.

Why 8-ft. pocket door or less? Because Sing’s True Flat Team uses additional patented and patent-pending anti-warp technologies which take into account the size of the large pocket door, the surface materials, its application, whether it will be an interior pocket door or exterior pocket door, how often and when will it be used, and in some cases which direction the door faces to determine the exact components within his composite hybrid core.

Sing is well known for using this patented method to build the best pocket door in the world because his factory is staffed with both the craftsmen and equipment (the biggest panel saws, glue machines, sanders, and presses in the industry) to create large pocket doors in a reasonable amount of time.

The biggest and best pocket door manufacturers, millworks, and custom pocket door builders rely on Sing’s ability to deliver such high precision pocket door cores in time and within budget to get the job done, without having to risk the embarrassment of selling a potentially warping large pocket door.

Sliding Pocket Doors

Sliding pocket doors are an elegant way to divide two adjoining spaced provided you have adequate wall space to host pocket door cavities to accommodate this type of in wall sliding door. The most attention harvesting approach to sliding pocket doors is to include a double pocket door in your presentation, where each slider separates in opposite directions to be housed within the wall for a concealed sliding door effect.



Standard sliding pocket doors, like a Home Depot pocket door or a pocket door Lowes make readily available will do the trick in most cases.


As you may already know or have guessed, if a pocket door were to warp, this could render the door inoperable, and if you’ve had a home with sliding pocket doors, you are already aware that at certain times of the year your sliders are inoperable because they have moved according to changes in the environment, and forcing them open or to close them will cause damage and result in costly repairs.

The entire door industry is aware of this and makes accommodations for the movement of standard sliding pocket doors. In fact, AWI standards allow a quarter-inch variance along any point of a standard sliding door, citing a .25-inch bend as “normal” and as such any 7 ft. or less door with ¼” warp is considered straight and not warped.

If a door has a bend which measures over a quarter of an inch of deflection in either direction among a 7-foot span, this is considered as a warped door. Therefore, all professional hardware and door manufacturers consider these variances in the hardware and installation of all sliding pocket doors and their components as standard operating procedures.

Large Sliding Door Strong Straight Warp Free

Problem Sliding Pocket Doors

This is the main problem when considering a sliding pocket door addition to your design or project, the potential warping of the material of which the door itself is made of. Of course, you could make the door of solid steel, to prevent it from warping, which many a frustrated door engineer has done, but such a heavy in wall sliding door presents a whole new set of problems which may compromise the supporting structure or certainly cause extra stress and strain on the hardware which will require more ongoing maintenance over time.

Solution Sliding Pocket Doors

Then, one day, inventor Peter Sing introduced the sliding pocket door solution which eliminated the issue of warping sliding pocket doors altogether. He is now the president of Sing Core, the manufacturer of his patented and patent-pending sliding door technologies which enables sliding pocket door companies, millworks, and custom door manufactures to create a warp-free door of any size, even large oversized pocket doors over 7 ft. to 50 ft.

Utilizing Sing’s hybrid solid reinforced vertical grain torsion box composite sliding pocket door core, builders of pocket doors are able to create the most lightweight large high precision (Sing’s core boasts .006-in. tolerances) door slabs that are stronger than steel pound for pound and can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50-years!

50-Year Warp-free Sliding Pocket Doors

The only 50-year guaranteed sliding pocket door core technology is changing the way doors are made across the board, affecting both interior pocket door as well as exterior pocket doors, because Sing’s patented core provides so many additional benefits besides non-warping performance over time.

The Sing solution also includes patent-pending supporting technologies which can be included in the base-door design which provides anti-warp characteristics which can be adapted and changed according to skin facings on said door. This enables custom sliding pocket door manufacturers to create an enormous wood pocket door that will not warp, unlike a solid wood pocket door which can be guaranteed to warp not long following installation.

More Benefits of Having Sing Core Inside

Besides the warp-free enhancements, Sing, packs extra insulation inside his hybrid solid sliding door composite core material for sound-deadening capabilities and added climate control. The lightweight characteristics of Sing’s door core material is off the charts when factoring unparalleled strength, resilience, and anti-deflection. All saving the expense of using heavy duty hardware (not necessary for Sing’s lightweight alternatives) and nearly cutting out regular ongoing maintenance associated with heavy or warping sliding pocket doors.
