Sliding Doors vs Pivot Doors

Both sliding doors and pivot doors are staples in the home and commercial building space. Both provide the same basic function: allow or restrict access to an area. The way they perform that function, however, is different, and thus each one has its own sets of pros and cons to consider when planning out your project.

Pivot Doors – Pros

Pivot doors are the classic when it comes to most doors. Rotating on an axis near the back end of the door, these doors swing out (or in) when opened and can be designed in many different ways. A pivot door may be a simple flat wood interior door or an extravagant and ornate exterior door, or anything in between. They are easy to operate, easy to install, and the standard door type.

Pivot Doors – Cons

While pivot doors are fantastic options, they do come with some limitations and drawbacks. One, a pivot door requires a much larger footprint than a sliding door, as it has to swing open in at least one direction. This means that the area around a pivot door must remain clear and unused, which can limit the available floor space in a small room or tight hallway. Additionally, pivot doors are only supported on the end with the pivot point, meaning they are constantly pulling down on their hardware and can wear on them much more over time. This can also limit their stability in some circumstances.

Sliding Doors – Pros

Sliding doors are becoming increasingly more common in both home and commercial applications. Architects and designers are choosing sliding doors more often as time goes on due to their sleek and modern appearance, as well as the benefits they provide. There are two main options when it comes to sliding doors, the standard and what is called a “pocket door”. Sliding doors take up significantly less floor space than pivot doors regardless of which style is used, and they can be designed to be much larger than the standard pivot door without near as many complications. In addition, sliding doors are mounted on at least one, sometimes two roller tracks. This means that they are evenly supported across the width of the door, leaving no areas lacking in support or wearing heavier on the hardware. Sliding doors that slide into the nearby wall are even more safe, as they are only ever exposed to traffic or weather when closed.

Sliding Doors – Cons

While sliding doors take up much less floor space than pivot doors, unless you’re using a pocket door, they do take up wall space. Arguably still less intrusive than pivot doors, however a standard sliding door will need to slide over the wall near it when opened. Depending on the size of your sliding door, this could lead to a large amount of nearby wall space that must be left clear. If you’re using a pocket door, however, this issue is completely resolved, as the door slides entirely into the wall. Sliding doors are also a little bit more complicated to operate, though this is hardly a factor as they are still simple to use.

Conclusion

No matter which door type you choose, you can build a beautiful and functional piece. If you’re considering these options, we encourage you to look through the Sing Core website to learn more about these door types and how Sing Core can help you!

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.

The Sing Core Sliding Door Revolution

Sing Core Sliding Door Revolution

Sliding Doors are taking over the industry. We recently updated the Sliding Door page on our website as part of an effort to keep things updated and more accessible to you, the reader, but also to go over why we believe Sing Core is the best choice for your large or custom sliding doors. In this article, we’ll touch on a few of these reasons, and afterwards we encourage you to go view the new Sliding Door page to see all of the changes!

Big Doors are Better with Sing Core

Big doors can be a big problem. Regardless of how well designed they are, if you’re using heavy, low quality, or warped materials, either one of those could limit its function. Especially with sliding doors, where precise construction and proper installation is essential to its long term functionality.

The biggest issue with large doors is their weight, as a heavy door wears significantly more on the hardware used to mount it, significantly reducing its lifespan. With sliding doors, this is particularly seen on the rollers and tracks used to open and close them. The heavier a sliding door is, the harder it is to open and close, and the more likely you are to have to replace or repair major parts of the structure, if not the entire door itself. Plus, a larger door is more likely to warp, and a warped sliding door becomes practically impossible to close and seal properly.

With Sing Core, these problems are removed from the equation entirely. Weight is no issue with our patented and patent-pending panels, as they are incredibly light while still being stronger than steel. This, in turn, reduces the damage done over time to the hardware and extends the life of the door. Plus, Sing Core panels are guaranteed to remain warp-free for 50 years, which is one of the most common reasons sliding doors fail. The larger a door gets, the more surface area it has, and the more likely it is to warp. With Sing Core, no matter what size your door is, our panels will never warp, guaranteed.

Sing Core Sliding Doors vs The Rest

Aside from making great large doors, what qualities does Sing Core have over the rest of the options? One major factor is ease of opening. Many people know the pains of trying to open a sliding door that is wedged into the track and wrenching your arm as it stops suddenly, or the great efforts that go into heaving a sliding door open at times. Sing Core panels are lightweight and dimensionally accurate, ensuring the door is easy to open and close and doesn’t get stuck on its tracks.

Sing Core panels can also be made to nearly any build specifications, meaning with us you can get a completely custom door that is guaranteed to perform, while with other options you may be limited to what’s “in stock” for your projects.

Overall, we recommend Sing Core panels for any sliding door project. Regardless of size, shape, or any other factor, feel free to request a quote to get started on your perfect door journey!

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!

Protect Your Home From the Winter with Sing Core

Sing Core and Your Warmth

As we hit the half way mark of the 2022/2023 winter season, many are finding that their homes lack proper insulation in many different ways. One of the main reasons your home may not be holding warmth is your exterior doors. Doors are often poorly insulated, if even insulated at all. A poorly insulated door can surge your heating bill up, as it allows warm air to leave the home and cold air to filter in unrestricted. A door made with Sing Core’s patented honeycomb panels is guaranteed to improve your internal climate, as they are well insulated, lightweight, and can be made to fit any door size.

Why Choose Sing Core?

Sing Core doors offer many advantages over the standard options, and are the industry best in making high quality, durable, and lightweight doors. Our products are made with a laminated honeycomb core, allowing you to choose nearly any door design while still maintaining that high end Sing Core result.

In addition, our doors are guaranteed to be warp free. Doors can warp slowly over time, especially in areas with constantly changing weather. Rain, snow, freezing temperatures, and many other factors can lead to your door warping, and even the smallest warp can change the entire feel of your door. Sing Core doors are guaranteed to not warp, meaning you’ll always have a smooth and straight entrance.

We also offer a 50 Year Guarantee on our products, promising to stay sturdy and straight through that entire time. This brings you peace of mind to know that you will always be satisfied with your door, as it will stand the test of time regardless of the conditions.

What Are The Benefits of Sing Core?

In addition to the high end insulation and 50 year guarantee, our doors are also incredibly sturdy and lightweight. A typical door can be one or the other, but at Sing Core, we make door panels that are durable, without weighing down the hinges and being difficult to move. Because of this, we can make doors of nearly any size, further broadening your options with elegant tall doors, large garage doors, and many others. Our panels are also sound deadening, offering additional uses as interior doors for studios, or even exterior doors in loud areas.

What Kind of Doors Can Sing Core Make?

Nearly any door is an option when using Sing Core. Exterior doors, interior doors, large doors, pivot doors, sliding doors, and garage doors, among many others, all become a possibility with our amazing product. Plus, these various applications will all have the same benefits, so you can have an insulated garage door, a lightweight large door, and more.

Patio Doors

When you’re not just looking for any patio doors, there’s a good chance you’re looking high and low for the best patio door to suit your needs, your particular taste(s) as well as beautiful patio doors. Normal, off the shelf patio doors are not going to suit what you want in a patio door. Chances are you’re looking for the best patio doors, doors that are not your run of the mill patio doors, but unique one of a kind patio doors.

If you really want the best patio doors, you will need to enlist the skills and artistry of a local millwork or custom patio door manufacturer.

Sliding Patio Doors

Sliding patio doors are the most prevalent and sought after styles of patio doors, which can and often do include several sliding patio doors in succession including overlapping sliding patio doors which are also called bypass sliding doors because one door slides over another door panel, which may or may not be a sliding patio door. Depending on the design, one or more patio doors may be stationary.

The best sliding patio doors featured in high end homes are made with wooden sliding doors that feature large glass window lite cutouts. It stands to reason, if you’re going to have a nice patio, you’re going to want to enjoy it both from the inside and the outside of your home. So, unless you’re primary concern is high security patio doors made of Kevlar or featuring Lexan clear polycarbonate, you’re going to want sliding patio doors with a view (glass installed).

French Patio Doors

Those sliding patio doors with the big glass cutouts? We call them French patio doors. By definition a French door is a usually a wood door featuring a large window glass pane. Sliding French doors allow you to enjoy the beauty of the outdoors regardless of the time of year. French doors are Eco-friendly in that they maximize the availability of the natural lighting.

If your French patio doors have Sing Core inside, they are lighter in weight and also insulated for climate control as well as possessing sound deadening qualities, thereby maximizing your investment in the most Eco-friendly French patio doors.

While the sliding French patio door is intended to provide access to and from the patio area, they are also elementally and visually impressive enhancing the overall appearance of any patio access area. Sliding French patio doors are by far the most elegant patio doors, and backed with Sing Core’s 50 year warp-free and structure guarantee, are the most sustainable patio doors.

Wooden Sliding Doors

Since wooden sliding doors are the preferential choice of designers, architects and owners of the most expensive homes ($20 Million & up) chances are these are going to be wooden sliding doors which are featuring large lite cut outs and are likely to be very tall, which could be 9 to 16 ft. tall wooden sliding doors, or even taller sliding French patio doors. Wooden sliding doors (especially if they are large sliding doors) present a number of challenges for the architects, designers and millworks or custom door manufacturers who build them. The number one problem with any long span of wood is that it will warp. It’s not a matter of if the large wooden sliding door will warp, but when it will warp.

That’s why it’s so important to have Sing Core inside your large wooden sliding doors, because a warped wooden sliding door which does not open or close is not a door at all. Although, if your door has a large window glass pane lite cutout, you will still have the view, so even if the door fails, your wood French patio door can be a French patio window.

The most conscientious, wisest and efficient designers and architects increasingly are specifying that all their large wooden sliding doors and wooden French patio doors have “Sing Core inside.”

Sliding Door Design

The design of sliding door, and sliding doors in particular, can be complex and may require a true team approach to the sliding door design. The architect can specify the sliding doors, and the designer (who may also be the architect or the owner) knows what they want. The concerted efforts of the custom patio door builder or manufacturer, the millworks, (as well as Sing Core, if specified) and the install team, must work in tandem to solve all the pending challenges that may arise from the sliding door design.

Extra care must be taken in the selection of the sliding patio door hardware, ensuring that it is rated for exterior use, and also matched to the weight of the sliding patio door as it was designed. The weight of the sliding patio door dictates the types and styles of sliding patio door hardware which will be necessary for improving performance and reducing maintenance over time.

For patio doors that have solid warp-free Sing Core composite core inside, these patio doors will be lighter in weight than other solid core doors, reducing the cost of what otherwise might require heavy duty sliding door hardware, which can cost many times the cost of the sliding doors themselves.

Modern Patio Doors

In this day and age, modern sliding doors need not adhere to the same design characteristics as their sliding patio door forerunners. In the most contemporary architectural designs custom lite openings can be designed which contrast wildly in comparison to earlier traditional designs.

It is common for Sing Core to pre-cut custom lite openings in modern patio doors based on the visionary drawings of the contemporary architect, designer or owner.

By altering and creatively designing the glass openings in an otherwise sliding French door configuration, a unique glass design and install can increase the effective curb appeal and radically enhance the perceived value of a home, when the owner desires to be uniquely separated from the pack.

Plus, high end modern patio doors need not be limited to being manufactured of wood. You could be looking at modern hot rolled steel doors for your patio. You might see these highly individualized, one-of-a-kind patio doors made of hot rolled steel, copper, or concrete, because custom patio doors with Sing Core inside could be made of any available flat building material.

50 Year Patio Door Guarantee

It’s obvious that your patio doors are exterior doors and exterior doors are always problematic because one side faces the inside of the structure and the other side faces the elements. Only professional patio doors with Sing Core inside can be guaranteed not to warp, bend, twist or otherwise fail for 50 years, including full structure warranty.

The Best Sliding Doors

Sliding doors are the perfect way to complement to your home’s individuality. Sliding doors are ideal for smaller spaces, due to their space saving nature. Some sliding doors even slide completely out of sight and into the interior of the adjoining wall. These doors create a pristine and merely seamless entrance to any room. We are glad to provide you with the best sliding doors in the industry.

Sliding doors consist of one or more door panels that open by either gliding on a track or hanging from rollers mounted above.

Interior Sliding Partition Doors

Interior sliding partition doors are all the rage these days when maximizing and consolidating space is of high importance. Nobody knows that better than our friends in New York, where most of our sliding room dividers are installed to quickly create an insulated sound deadening room partition.

Interior Sliding Partition Doors

Our premiere interior sliding partition doors allow anyone to reconfigure living space quickly and easily using sliding partition doors with patented Sing Core inside. You can easily add a sliding hanging door using inexpensive barn door hardware to create a separation between rooms, or you can divide an entire room in half by using multiple sliding barn doors in a side-by-side configuration to create separate rooms, then open them back up when you want to access the entire space again.

Interior sliding partition doors can take on many appearances, as sliding doors, or many doors can be assembled as a modular moveable partition wall on site and installed without the heavy equipment necessary to hang an enormous sliding room divider and room partition.

What makes interior sliding partition doors with Sing Core inside so in demand in NYC?

The demand is greatest in NYC due to the city’s tendency to grow upward. Tenants are discovering new ways to divide up the living space, and entrepreneurs are finding new ways to divide office space. Installing a sliding room divider or room partition is an inexpensive approach. Bit when your room dividers’ doors have Sing Core inside, you enjoy other benefits that can not be achieved any other way.

Inventor, Peter Sing, has provided to room partition industry his patented Sing Core material to make the best interior sliding partition doors in the industry. Here are the characteristics you can expect,

1 – Lightweight. Sing Core is a lightweight solid hybrid sliding partition door that weighs in at a fraction of any other wood-based solid core door, making it easier to handle, maneuver, and install.

2 – High Strength. Even though a sliding partition wall with Sing Core inside is lightweight, it is not weak, as Sing’s patented core is stronger than steel pound-for-pound and has been independently University rated at 660 PSI, and is used in impact door applications.

3 – High Precision. Sing’s patented core is one of the highest precision cores in the industry sporting +/- .006 in. tolerances, which is of concern for the high-end projects, like the Freedom Tower, One World Trade Center, the tallest building in the country.

4 – No Size Limit. Floor to ceiling, no problem, 20 to 50 ft. wide, no problem. Due to Sing’s lightweight, high strength, and high precision, the largest door companies and best millworks in America are able to make enormous sliding partition doors of any size.

5 – Fully Insulated. Sing’s hybrid solid core doors are fully insulated for sound deadening and climate control, which is used in soundproof and refrigeration applications. Tenants enjoy the insulation for controlling heating and cooling while increasing privacy and security.

6 – Any Type of Door. A door with Sing Core inside could appear as any type of door for the prefect aesthetics and could be made of any desired flat building material. Most common are natural wood grain, MDF, and metals.

7 – Warp-free. The most impressive characteristic of Sing’s room divider doors is that they are guaranteed not to warp, bend, twist, or otherwise fail for 50 years. Undoubtedly, to date, there has been no way to build such an impervious non-warping door. That is, unless you use Sing’s core.

The biggest door companies and best millworks in the USA use Sing’s patented core, especially in their projects calling for doors that are over 4-0 8-0, because they say,

“There is no other way to do it.”

If you are an architect, designer, or door engineer, and you are considering sliding door room dividers for your next project, you would be well advised to spec Sing Core inside your high end and modern sliding doors used as partitions, or operable partitions and movable walls for flawless performance over time.

And don’t forget, it is the only way to create a sliding door with a,

50-year Warp-free Guarantee

Doors with Sing Core inside can be guaranteed not to warp, fail, twist, or otherwise fail (including full structure) for 50-years.

Secrets of Warp-free Large Sliding Barn Doors Revealed

Large sliding barn doors are an important feature in the biggest warehouses and industrial locations in the United States, from military to aerospace a big sliding barn door is often specified in the architectural designs for practicality and ease of use. But the larger the door opening the harder it is to keep these huge sliders from warping. If you cannot keep the door straight, you may have reduced access due to door failure.

Ceiling mounted barn doors 14 ft. x 3.5 ft. x 2.5 in.

For years, inventor Peter Sing’s patented warp-free sliding barn door solutions have been the answer to these massive sliding barn doors, which using his patented and patent-pending anti-warp solutions can be built lightweight, high strength, and be guaranteed not to warp for 50 years, unheard of before the invention of Sing Core.

Interior Barn Doors

As interior design has evolved, the integration of interior modern barn doors in everything from residential to commercial projects has seen rapid growth. Of course, standard-sized interior sliding barn doors do not pose much of a challenge, but if the door exceeds 8 feet tall or a 4-foot width, now you are heading into dangerous territory if you are hoping for a non-warping sliding barn door.

Commercial Steel Barn Door

Warped Large Sliding Barn Doors

Regardless of the application, large sliding barn doors are going to be problematic, so much so that years ago, the biggest door companies in the USA excluded offering the large barn door from their door schedules, instructing contractors to seek out custom door makers or millworks, because they could not cover these enormous sliding barn doors with any warranty because they were destined to warp and fail not long after installation.

After a while, even the millworks started turning down jobs for large sliding barn doors for the same reason, too many service calls during the warranty period, though this did open a door for door service companies whose job it was to regularly maintain doors, though this was extremely expensive for end user of the warping big sliding barn door.

Not Faulty Design

The problem, it turns out was not with the design, as large sliding barn doors were both stylish and practical, so the architects could not be blamed. The problem is with the limitation in building materials. A dimensionally stable door could be made of a thick solid material such as solid steel, but the bigger the door gets, even solid steel will move according to changes in the environment. Sing is able to bring the ideas of the architects and designers to life in such as way as to provide a 50-year solution to such visionary ideas.

Warp-free Solution

When inventor Peter Sing introduced his warp-free technologies to the large sliding door companies, they embraced Sing’s solutions for warped large sliding doors. Thanks to Sing, they were able to get back into the oversized door market once again. According to them, in their own words. Sing’s core,

“Is the only way to build a lightweight warp-free large door.”

The only way.

Commercial Steel Barn Door

A Door is Not a Wall

It is important to learn what the core structure is made of. Doors are not the same as walls. Doors need to move repeatedly everyday while walls are permanently placed. Walls commonly use 2” x 4” framing methods which do not work well for building doors. If the structure of the door is not strong, it will not feel or sound very solid. When you close the door, there will be rattling sounds and/or it can deform over time. It is very easy to tell, all you have to do is close the door and hear how strong or solid the door is made. It may look the same, but it does not sound the same. You can tell the difference by knockings on the door, you can tell what is inside. Solid like a rick but still light like a feather when you swing the door closed. The structure of the door that makes the difference, not the door skin.

You Want a Warp-free Large Sliding Barn Door

We already know you want a large warp-free sliding barn door. How do we know? Because Sing’s email servers are filled with people asking about how they can get a sliding barn door with Sing Core inside? Unfortunately,

Sing Core Does Not Sell Doors

Even though sliding barn doors with Sing’s core inside are among the best doors in the world, Sing’s factory does not build doors. Rather, they provide the raw warp-free base materials to the door building companies and millworks who create the enormous warp-free sliding barn doors, that the inventor is credited with, even though Sing only provides the base material. So, if you really want one, just contact your favorite door builder or millwork and tell them you want a door, “with Sing Core inside.”


What is the Secret?

How to Build a Large Sliding Door

Undoubtedly, you have wondered how does Peter Sing build such large lightweight sliding barn doors that are stronger than steel pound for pound and can be guaranteed not to warp for 50 years? Following are the methods that Sing uses to build warp-free doors of any size, made of nearly any flat building material, secrets revealed.

First, the architect or door engineers, specify the door dimensions and the material that the door will be made of, and submit the specs to Sing’s True Flat Team. The team goes to work, gathering all the data necessary to predict what the challenges will be for the door. Questions like, will it be an interior or exterior door? Will it be exposed to the elements? In what geographical location will the door be installed and at what altitude? Which direction will the door face?

The team starts with Sing’s patented rigid foam reinforced torsion box core, then add additional patent-pending anti-warp technologies to compensate for exterior door skins and environmental concerns.

That is the secret inside these huge warp-free doors.


How Can You Ship Such Large Doors?

Of course, the military can do amazing things with transportation that cannot be accomplished by mere mortals, so Sing has created a modular technology that supports his 50-year guarantee. In this manner, any size of door can be built and shipped in high precision sections that are assembled on-site.

Joining a modular door shipped in sections

This saves so much on shipping and handling costs, and if the large door needs to fit in an elevator or tight doorway, not problem. High precision modular solutions are the answer. Sing Core has built many large doors that are joined on-site without any warping.

Don’t try this at home. Average dowels and even larger biscuit-joining will not prevent door warping. Let’s say you wanted to build a pair of 10’ x 20’ double barn doors that were 2-inches thick. Stacking and joining four 5’ x 10’ x 2” panels together will not be an easy task. But Sing Core has had many years of experience with oversized doors, and has been devoted to solving the common issues with larger modular doors.

If you have a good budget, high precision demand, and no issue accessing the job site then a one-piece large door panel is the way to go, if it can be shipped to your location.

Otherwise, modular door sections joined on-site will be the best option. There are two major factors to achieve high quality when building large doors. One is to make sure there is no warping once the modular sections have been joined. The second issue is maintaining a high precision joint line so that it is not noticeable. This requires a very high precision core to achieve. Sing Core is the most precision door core available, with a tolerance of ± 0.007”. It is important to be sure that the thickness of the core is within these tolerances.

Weight and Strength

Strength plays a key factor when building larger doors. Traditional door building methods may dictate that strong doors are heavy and lightweight doors are weak. Weight is a major issue with oversized doors. Heavy doors are significantly more expensive due to additional structure costs, higher labor costs, and extra shipping and handling costs. Heavy door core does not mean that it will have high strength and the larger the door is, the more strength is necessary to maintain a long lifespan.

When using Sing’s metric interior technology where every two inches is mitigating the potential of the exterior surfaces to move two to three inches at a time. Rigid foam insulation is used inside these small torsion box grids made of vertical grain natural wood fiber which pushes and pulls against the surface material’s tendency to move, keeping it straight when it would otherwise warp. It also provides a huge weight advantage over any other method of trying to keep a door from moving following installation.


What type of skin is best to build a large modular door?

Paint Grade – It is easy to hide the seams. Seams can be almost unnoticeable if modular sections are joined with a Sing Spline. If the spline is made of solid wood, it can move or warp after the moisture levels change and it will be reflected on the surface of the door. This can cause the surface of the door to crack after the seasons change.

HPL (High Pressure Laminate) – See how precise the joint is using only a Sing Spline. HPL is available in a wide variety of patterns. The best choice for HPL is a vertical pattern to help the joint blend into the surface. HPL is a good choice when ordering one of our modular oversized doors. The patterned HPL allows the joint line to be hidden in plain sight. The door can be as big as 12 feet tall and 40 feet wide without having any noticeable seams.

Metal – If it is paint grade metal, the seam can be filled with joint compound and then painted making a seamless joint. Metal doors are traditionally very heavy, but with Sing Core inside your metal door can weight roughly 1/3 of a traditional metal door. You can choose from any type of metal you would like, but our most commonly made metal doors are Aluminum or Cold-Rolled Steel. Click here to see a paint grade Sing metal door.

FRP – FRP, or Fiber-Reinforced Plastic, can be used to make very large doors and very durable doors. FRP can be smooth or have a textured surface. It is much more visually appealing and functions much better than solid wood which has potential to crack, warp, twist, and cup. Besides, solid wood weights a lot more than Sing wood stave planks. Sing wood stave planks are the ideal material to replace solid wood for such jobs as, doors, tabletops, post and beams, and many more. An advantage of choosing wood staves are that they are much more precise than solid wood because their tendency to move over time is minimal in comparison. On the other hand, wood staves are much harder to match with surrounding patterns than a wood veneer skin.

Wood Veneer – Wood veneer has an average thickness of 0.020″-0.030″ and is very difficult to hide joint line in the face of the panel. Wood veneer is often much more challenging because it is usually very thin, normally only 0.020” thick. We always suggest using thicker wood staves which are usually 0.125” thick rather than veneer. However, Sing Core has a proprietary technology to make a veneer panel seamless as large as 10′ by 16′. This requires the veneer to be staggered and hot-pressed. It is very costly to use veneer, oftentimes we use wood staves to build larger doors.

For a tighter budget, we recommend using a paper backed veneer which only requires being cold-pressed. Sing Core provides the smoothest MDF skin for our clients to hot-press. Cross banding is not required with our smooth and high precision substrate, which may be hard to believe for some people. We have been doing this for many years with our innovative technology. We always recommend that our clients purchase our veneer substrate, complete with the same warp-free guarantee, and hire your local veneer contractor or do it yourself to save some money. One advantage to using a wood veneer as the skin for your door panel is that veneer can be easily matched to the surrounding area. One disadvantage to using wood veneer skin is that it is not well suited for exterior purposes, such as entrance door, and it can be difficult to repair if damaged. Veneer skins are the also limited to the maximum door size of 10′ by 16′.
