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. This style of door is very sensitive to weight, as the entirety is often hanging from the top of the door jamb. If the doors are too heavy, this can cause some serious and potentially dangerous issues. Sing Core have the solution to these issues.

Traditionally built sliding doors have a tendency to warp over time. That may not seem like a big deal, but it can make the door fall from its track. It is very dangerous when this happens especially when someone is nearby… Ouch! Whether your sliding door is a patio style door or a sliding closet door, its best to have it lightweight and truly flat for the entirety of its lifespan.

Large Sliding Glass Doors

Sliding glass doors add that special element which bridges the gap between any structure’s interior and the exterior vistas that may be surrounding the area. This has a huge impact on real estate with a view, maintaining a connection between the safety and security of being indoors with the beauty which exists on the other side of the glass.

Large sliding glass doors, sliding doors of immense size, or floor to ceiling doors with glass are not only impressive, but they increase the energetic connection between indoors and outdoors exponentially. In essence, the bigger the sliding glass doors, the greater the impact on those who behold them.

Sing Core’s pride in the whole “bigger is better” concept and their unique ability to create an enormous door with many features unattainable any other way, translates into empowering contemporary architecture, modern designers, and door engineers to create fabulous displays without having to block out any user experience.

You will find sing Core’s large sliding glass doors in not only the most luxurious homes in the world, but amidst ornate hospitality, commercial, and industrial applications, where not only size matters, but high precision, superior functionality, and longevity over time, without costly maintenance.

It is now more common for Sing Core to participate in a big door moving glass wall project for a Fortune 500 company, multi-panel opening glass door systems for aerospace industry, or sliding glass patio doors for the best upcoming tour of homes in your expanding upscale neighborhoods.

Design Large Sliding Glass Doors

The design capabilities of Sing Core working in concert with architects results in far superior moving glass wall systems than could every be accomplished otherwise, and you know, size is not a hinderance, due to inventor Peter Sing’s patented and patent-pending large sliding glass door technologies.

The glass framing options of Sing’s patented sliding door core empowers architects and designers to let their creative juices flow. You are no longer limited to where and how you can add glass inserts. If you can draw it, Sing’s true flat team can create the specialty lite cutouts you envision, without compromising strength or structure, as you say, “goodbye,” to old school rectangular glass inserts.

Some of the attributes you can enjoy about Sing’s revolutionary new tech include being able to build larger sliding glass doors which weigh far less than other sliding glass doors comparatively. These sliding glass doors which are lighter weight reduce the cost of articulating hardware, which is based on the weight of the door. The lighter in weight the door, the less expensive the hardware will be, also, the less energy necessary to operate sliding-glass door mechanism. The weight saving also contributes to greatly reduced maintenance due to less stress and strain on the structure and sliding door hardware during operation.

French Doors

French doors with Sing Core inside are by far the most popular sliding doors which Sing’s company help to make and take to the next level in sliding glass door design. While the most popular surrounding exterior door skins featured on Sing’s French doors are natural wood grains, followed by sliding metal glass doors, but your French door could feature almost any flat building material, as they have been made with aluminum, brass, copper, cold rolled steel, diamond plate steel, fiberglass, FRP, galvanized steel, HPL, hot rolled steel, Kevlar, Masonite, MDF, stainless steel, etc… you get the idea.

Sliding Patio Doors

Sing’s sliding patio doors are huge in that their ability to outperform any other type of exterior door is unquestioned. Sing’s patented exterior door core is fully insulated and is extremely strong. At 660+ PSI, this door core material is stronger than steel pound for pound.

The largest door manufacturers in the world use Sing’s core in their large oversized exterior door projects, as it’s the only way known to build a large patio door without it moving in response to the elements which surround the door.

It is well known that big doors move according to changes in temperature, barometric pressure, sunlight, and any variety of environmental conditions, that is, unless it has Sing’s patented and patent-pending technologies inside.

“This is the only way we know of to build a large door and keep it straight.”

Add a large glass lite cut out and you have yourself a hybrid French patio door, enjoying the best of both worlds.

50 Year Warp-free Guarantee

Unheard of elsewhere in the industry is inventor Peter Sing’s 50-year warranty which accompanies every door made to specs with sing Core inside. Each big sliding glass door is guaranteed not to warp, bend, twist, or otherwise fail for 50 years for the application the custom-sized sliding doors were designed for.

Thanks to Sing’s core, sliding glass doors can be made without limitation to size whatsoever, and the design possibilities are endless.

So, if you’re considering the addition of large multi-slide door, exterior sliding glass doors, or any type of extreme sliding & folding glass doors, you might want to consider taking your project to the next level by specifying that you want, “Sing Core inside,” all your upscale large scenic sliding door systems.

“If we couldn’t do it, we couldn’t say it.”

~ Peter Sing



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

Sliding Glass Doors

Sliding glass doors are the most prevalent and sought after styles of patio doors, which can and often do include several sliding glass doors in succession including overlapping sliding glass 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 glass doors may be stationary.

The best sliding glass 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 level patio doors which can be made of Kevlar and featuring Lexan clear polycarbonate, you’re going to want sliding patio doors with a view (glass installed).

Sliding Glass French Patio Doors

Those sliding patio doors with the big glass cutouts? We call these sliding glass doors, “French patio doors.” By definition a French door is a usually a wood door featuring a large window glass pane. Sliding glass 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.

For The top of the line, highest end sliding glass doors, look no further.  We can make panels that will shock and awe even the competition.




If your French patio doors have Sing Core inside, they are lighter in weight and also insulated for climate control and also sound deadening qualities, maximizing your investment for 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 by far the most sustainable patio doors.

Wooden Sliding Glass Doors

Since wooden sliding glass 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 16 ft. tall wooden sliding glass doors, or taller sliding glass French patio doors. Wooden sliding doors (especially if they are large wooden 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 of 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, even if the door fails, your wood French patio door can be a French patio window.

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

Sliding Glass Door Design

The design of glass sliding doors, and sliding French doors in particular, can be complex and may require a true team approach to the glass sliding door design. The architect can specify the glass sliding doors, and the designer (who may also be the architect or the owner) knows what they want. The concerted efforts of the custom glass 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 glass sliding door design.

Extra care must be taken in the selection of the glass sliding patio door hardware, ensuring that it is rated for exterior use, and also matched to the weight of the sliding patio glass door as it was designed. The weight of the sliding glass patio doors 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 glass 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 sliding 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 sliding patio doors need not be limited to being manufactured of wood. 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.
