Dual Pocket Doors Made with Sing Core

People often think of doors as simple barriers or entryways, but at Sing Core, we know that a door can be much more than that. Doors can be elegant accents to a room’s design, or a seamless way to change a room’s layout. If done right, they can even be part of a room’s main design feature, such as in the example we’re showing you today.

This customer needed a way to separate two areas of the house, but was fairly limited in their options due to their design preference. Due to the height of the room, a standard door would not work unless they expanded on the center wall, which would majorly damage the flow and beauty of the room. A normal sliding door would work, but the dimensions would be incredibly difficult to get right. The door would have to be incredibly tall, yet narrow, which would need to be custom made. If this was done with traditional materials, the doors would likely be too heavy to work reliably, and could damage their hardware. Sing Core, however, was a great solution.

Because Sing Core panels are made with a honeycomb core, they are incredibly lightweight, yet still very strong. This means that the custom doors would still be sturdy and long lasting, but due to their low weight, they’d also be easy to use and be far less likely to damage their hardware. In fact, each of these doors only weigh 200 pounds, despite being over 13 feet tall.

These twin pocket doors measure 40 inches wide by 158 inches tall, and are 2.5 inches thick. This tall and narrow design worked beautifully for the room, though is definitely a non-standard size. Getting a door like this without having it custom made would be impossible, but luckily Sing Core specializes in large, high end custom doors.

A Sing Core door can be ordered to nearly any shape or size, and are strong, lightweight, and durable. One major concern with large doors is the possibility of warping, which gets exponentially more likely, and often exponentially worse, with larger doors. In the case of this project, even just a slight warp could ruin the entire system. A little bend or twist could leave a door stuck in its pocket, or scraping the side as it is opened and closed, damaging both the door and the wall nearby. There are many ways a warp can hinder or ruin a door, and often, warps are irrecoverable. Sing Core doors are guaranteed to never warp, and we can make that claim due to our innovative and patented honeycomb core. In fact, each door panel comes with a 50 Year Warp-Free and Structural Guarantee, so you can rest easy without worrying about your door failing on you.

Sing Core is thrilled to have had the chance to work on this beautiful project, and we hope to work on your next amazing project with you. Submit a quote request on our website to learn what we can do for you!

Lounge Room Door Made With Sing Core

Sing Core has been working with several universities regarding custom doors lately, such as with the University of Idaho and their arena door, the University of Alabama and a sorority house door, and now the University of Maryland with a custom sliding door for one of their lounges.

The University of Maryland worked with the brilliant people at USAM to get a large custom sliding door for their Heritage Community lounge room, and they reached out to Sing Core to make that work. Sing Core and USAM worked together to create a beautiful 3 piece modular sliding door. This door can separate into three panels along the sliding track, allowing for a custom setup to the walkway. It can also be completely opened and closed in order to really open up the area.

This large sliding door measures 168 inches wide by 120 inches tall, and is 2 inches thick. It contained splines to stiffen the panels and further improve the structural integrity, as well as a Formica finishing panel to give it that gorgeous end result. The door parts slide along an upper rail, which provides smooth and reliable operation.

This lounge room is in Pyon-Chen hall, one of two areas that make up the Heritage Community at UMD. It is a multipurpose location, intended to suit all sorts of recreational and student needs. Due to the location, the unique modular aspect, and the traffic, the designers of this door needed to make sure they got a high quality, durable, and long lasting product. That is why they went with Sing Core, and we are honored that they did!

Sing Core panels have many benefits over traditional door making methods, but there are three main ones that relate to a project like this: strength and durability, weight, and lifespan.

Sing Core doors are incredibly strong and durable, though surprisingly lightweight. This is possible due to the patented honeycomb core used within every Sing Core door. This honeycomb core provides exceptional strength and impact resistance, while also remaining amazingly lightweight. Where a traditional door panel may take several people to haul and install, most Sing Core panels can be carried by only two people, and even one if the panel is sized right.

The patented core and high grade materials used also give our doors outstanding durability, preventing many of the damages that would otherwise leave a door ugly or unusable. Especially being in a high-traffic area such as a university lounge room, durability, impact resistance, and longevity are vital. Heavy traffic walkways can see increased damage to the doors and walls around them. Sing Core doors aren’t easily damaged, and if they do receive a ding or scratch, they are easy to repair. In addition, all Sing Core panels are guaranteed to be warp-free for 50 years, which is unheard of in the door market. Warped doors are a massive problem, and unfortunately, many doors can eventually warp, regardless of the care put into making them. Sing Core doors, however, are guaranteed to never warp, and that is all thanks to the unique construction used to make them.

Sing Core is thrilled to have had the chance to work on this amazing project. Thanks again to the University of Maryland and the talented design and installation teams, as this would not have been possible without them.

Advantages of Sing Core for Commercial Applications

The Advantages of Sing Core for Commercial Applications

Sing Core has many uses and advantages in both home and commercial applications, though we tend to think more of the home applications than those in the office. We often undervalue the importance of things such as doors in the workplace, though they are essential to the daily operation and safety of our businesses.

Doors in the Workplace

The first type of door people often think of in the workplace is the front, back, or “entry/exit” doors. These are incredibly important when it comes to the safety and operation of a business, yes, but there are many more types of doors that are commonplace in commercial industries. One other common type is the standard interior, or office door. There are also “feature doors”, which are usually large, grand, and beautiful doors that act as the opening between important areas or large rooms (see this fantastic double sliding door at Laserfiche as an example). The other common types of door are security doors, room dividers, and more. Sing Core has experience making each of these, and our panels make an excellent choice for them.

The Advantages of Sing Core

While Sing Core’s benefits in the home and professional market are similar at their core, there are some features that excel in the industrial and business sectors. One such advantage is the ability to make large, custom, and lightweight doors with our patented core. Many businesses make use of these beautiful doors as their entry, or as a feature inside, but standard construction options lead to them being incredibly heavy, or come with many other downsides. Sing Core specializes in large doors, and we make them significantly lighter than other methods, while still retaining incredible strength and durability. Our panels are also guaranteed to remain warp-free and structurally sound for 50 years, so you never have to worry about your large custom door warping and becoming unusable on you.

Another major advantage to using Sing Core in the workplace is the insulating and sound-deadening properties of our panels. In a situation where privacy is important, like you’d expect in meeting rooms or offices where confidential information is shared, you need to ensure the security of that information with a door that reduces or eliminates the sound that passes through it. Sing Core doors do this incredibly well, as our insulated honeycomb design naturally muffles sound. This also makes it a must have for businesses close to a busy street, as the passive street sound can be a detriment to a workplace.

In addition to the sound-deadening nature, we also offer a Sing Core Security Door for applications where safety and protection are essential. If your business holds high-end electronics in specific rooms, or perhaps you have sensitive documents and information, you need to ensure that the door you use to secure those areas can hold up to any attempt to break in. A Sing Core Security Door is reinforced with steel bars to guarantee the safety of what you hold on the other side.

Summary

Sing Core products deliver many valuable properties to both home and commercial applications, and we encourage you to reach out to learn more about how Sing Core can fit in at your home or office!

A Low Cost Alternative Way to Build Very Large Sliding Doors

Although not as tough as our original one piece door designs with a 50 year guarantee, our segmented doors still come with our patented Sing Core structure inside and carry a 5 year warp-free guarantee. And, they can be sold at a much reduced price.

In the past, very large and oversize specified doors were often made as a single piece and shipped whole to the contractor for installation. This is particularly true of very large pivot doors and sliding doors. With modern door construction techniques pioneered by Sing Core large doors can be produced and shipped to the customer in several pieces. These segmented doors pass on savings to the customer while maintaining the highest quality standards for warp free door construction.

Benefits of Modern Segmented Door Construction

Building a door in sections provides numerous benefits without compromise in strength, lightness, and flatness:

See Them Come Together

More Efficient to Build

Constructing a door in smaller sections makes the door easier to handle in the factory and easier to produce in general. Having more manageable sections leads to quick and efficient construction, at a cheaper cost. Doors constructed with our modern sectional approach pass on savings to the customer.

Cheaper to Ship

Doors cores produced in sections are built to be convenient and cheap to ship compared to a door built in one piece. This may reduce shipping costs payed by the customer to receive their door purchase.

Easier to Handle

Very large doors constructed in segments conform to common sizes. When you receive the door at your site handling it in segments is usually more natural for workers used to traditional sized doors than and 4×8 materials than handling an extra large door. Leaving joining the door until it reaches the site cuts costs and saves time all the way from our factory to your building site.

Strong and Stable

Sing Core doors shipped in sections and assembled on site maintain the highest standards for strength, lightness, and straightness. At Sing core we guarantee warp-free performance of segmented doors for 5 years.

How to Assemble a Sing Core Segmented Door

Assembly of a modern sliding door constructed using Sing Core technology without any specialized tools and equipment.

1. Lay Each Panel Flat

The first step to join a Sing Core sectional door is to lay the panels on a flat surface. Any flat clean surface will work. For very large doors we like to use two straight beams laid on the ground along to hold the top and bottom of each door segment.

2. Slide a Spline in to One Side

Each spline and pocket are precisely cut to fit with strength. Our products are built with our 5 year warp-free guarantee in mind. Simply push or lightly hammer the spline in place on one side of the joint. Then your panels are ready to be fit together.

3. Joining the Panels

The final step in joining a modern sliding or pivot door is to press the sides together. This can be accomplished a variety of ways, including gentle application of a sledge hammer, a few ratchet straps, clamps, or any other means you have of providing joining force. Once joined, the door is strong and secure, built to last, and can be finished and installed as any other Sing Core door.
