Double French Doors Exterior

Exterior French doors are all the rage because if they’re done right, they offer superb safety and security while being Eco-friendly, lightweight, and fully insulated for increased sound deadening and climate control. The only way to create a sustainable lightweight pair of large double front doors that possess these double French doors exterior characteristics, which are also stronger than steel and guaranteed not to warp for 50 years, is with Sing Core inside.

 

Why is Sing Core so important for the most particular door afficionados in the world?

Granted doors with Sing Core inside may not be necessary for the masses, as standard doors available in standard door sizes are less expensive and adequate for normal everyday use. “Normal” doors move. The AWI standard for a normal 3-0 7-0 door is one-quarter-inch of movement, and the normal door industry from the door manufacturing companies, the hardware industry, and installation contractors all follow the guidelines of allowing a quarter-inch of movement without affecting normal door operation.

FRENCH DOORS

While you may think that glass is fairly stable, the frame which holds the glass (the French door) is subject to movement. It is the unforgiving glass which makes French doors more prone to failure, for if one corner is the slightest bit out of plum, the opposing diagonal corner will stick out like a sore thumb.

 

DOUBLE DOORS

Multiply the potential for failure times two, if you have two times the doors. A double door, two doors side by side, can potentially have uncooperative movement, even in normal-sized doors of 7 ft heights, double doors can have up to one-half inch of potential movement and still not be considered officially as warped doors, yet this exceeds the efficacy of the hardware, rendering the double doors inoperable.

EXTERIOR DOORS

To further complicate the problem with door movement over the life of a door which is more likely to move more often according to changes in the environment, and even more so, if one side of the door faces the structures interior and the other is exposed to the elements. This is the recipe for the perfect door disaster. That is why interior doors cannot be used as exterior doors. Exterior doors need to be made to different specifications to maintain the same “normal” quarter-inch movement allowed.

 

DOUBLE FRENCH DOORS EXTERIOR

As you may have guessed, by putting all these elements together in one set of doors, you have the makings of the greatest numbers of challenges associated with a single point of entry. Incredibly special attention should be in place when considering double French doors in an exterior front door application.

DOOR MATERIALS

While French doors may look like there is little at risk of compromising your egress point, there is much to take into consideration as each of the materials used in the construction of your exterior French doors has its own unique set of challenges as in integrates with the glass and its response to changes in environmental surroundings.

BIG DOOR PROBLEMS

The biggest problem with the door industry is with size. Normal movement of a door may be tolerable in a door that is 7 ft tall but once the door exceeds the 7 ft height, the rate of movement increases exponentially. The biggest problem with bigger doors is this increased movement which is referred to as door warp.

THE BIGGEST DOOR SOLUTION

Solving the problems associated with double French doors exterior is not a one-size-fits-all solution. Inventor Peter Sing’s patented and patent-pending door technologies are changing the way door are made around the world, and his True Flat Team is prepared to take on any unique and challenging combination of sizes, styles, and materials.

Solid Core Door Blanks

The new generation of solid core door blanks delivering high precision results for the most sustainable doors of any size, even exceptionally large doors, which are lightweight, stronger than steel, and guaranteed to remain warp-free for 50 years.

Inventor Peter Sing supplies the biggest and best door companies with his patented and patent pending warp-free door solid core door blanks which enables them to deliver what are commonly referred to as “the best doors in the world” to their clients who demand the top of the line for their homes and projects.

Sing’s solid core door blanks are unlike any other solid core door blank thanks to Sing’s inventions combined with the expertise of his True Flat Team which works hand in hand with architects, door companies, engineers, millworks, and custom door manufacturers, to achieve stellar results which are impossible to do any other way.

Sing’s clientele is often overheard gladly admitting that,

“There is just no other way to do it.”

To make a large door lightweight, so strong, that is fully insulated for sound deadening and climate control, and be guaranteed not to warp for 50 years, is inconceivable by any other known method besides using Sing’s unique inventions, science, and technology.

Until now, traditional solid core wood doors were destined to be heavy, especially if large in size, and most likely to fail not long after installation. Wood solid core doors in particular because, well, wood’s natural inclination, being a natural product that moves in response to changes in the environment in which it resides.

That’s why it is standard practice for door companies to exclude large oversized doors from the standard warranty which covers the rest of the door schedule. Large solid core wood doors are generally included on a waiver which exonerates the designers, creators, contractors, installers, and anyone else associated with those big, heavy doors from any responsibility for the door’s performance whatsoever.

Because until now, there was no way to make commercial grade solid core wood doors that had such high performance. For instance, a solid core wood slab door with Sing Core inside,

Moisture content is the main enemy for any large solid core MDF door slab, so proceed with caution when approaching the integration of any MDF door where moisture may be present. Areas to be avoided include bathrooms, laundry rooms, and kitchens, and MDF is not recommended for use as exterior doors.

In terms of high precision, Sing’s unfinished solid core door are straight and consisted with .006-inch tolerance and 660 PSI for strength. Its statistical data, like this, which makes Sing’s solid door core break the boundaries set by traditional building methods.

The most popular wood solid core prehung interior doors are found at your local home improvement warehouse, though you will not find solid core door blanks with Sing Core inside at those locations because Sing Core does not actually make doors. But what they do make is the only Eco-friendly lightweight solid core door blanks that will not warp, and Sing’s factory also provides a premiere unfinished solid core veneer composite door slab that outperforms anything else available.

At present, the Sing Core factory does not create any solid core door prehung but they do provide their exclusive warp-free solid core door blanks to the very best high-end door companies, millworks, and large custom door manufacturers in the world.

That might leave you asking,

How can I get a Sing Core door?

Even though you can not just run down to your home improvement warehouse and pick one up, its not as difficult as you might think. If you are working with an architect, he can simply spec a door “with Sing Core inside,” then Sing works in concert with the entire team to bring your dream door(s) to life.

If you are working with a local millwork, they will order up the solid core exterior wood door blanks that they need to get the job done and take it from there.

Your local door company is the best way to get a Sing solid core door prehung, because in most cases that is what they do. Unless they are a highly custom door manufacturer, most door companies get their doors made off-site (most of those doors are not made in the USA), then they (if necessary) finish and prehang them on site.

In this case, the door company will order up whatever Sing solid core door slab they need, finish, and hang the door, then you can pick it up, or you can arrange for door installation at your desired location.

Custom Wood Door Skins

Choosing the Right Custom Wood Door Skin for Sing Core Door Panels

Choosing the best custom door skin for your Sing Core door panel is key. The right finish balances beauty, budget, and function. Here’s a simple guide to five options: Wood Stave, Hot Press Veneer, Cold Press Paperback Veneer, HPL, and Wood Siding/Flooring.

Summary: Best Custom Door Skin for Your Sing Core Door

Pick based on your needs, budget, and style. Here’s a quick comparison:

Custom Door Skin Type Best For Key Benefits Considerations
Wood Stave Interior & Exterior Doors Stable, durable, repairable, great for large doors Slightly higher cost; best with staves under 6 inches wide
Hot Press Veneer High-end Interior Doors Seamless, beautiful appearance Expensive and delicate; not for exterior use
Cold Press Paperback Budget Interior Applications Affordable, natural wood look Hard to repair; not ideal for high-impact areas
HPL High-traffic & commercial use Durable, moisture-resistant, cost-effective Less natural texture than real wood
Wood Siding/Flooring Thick, solid wood look Strong, stylish, customizable Needs floating fasteners to prevent warping

For best results, pair your custom door skin with Sing Core’s patented core technology. This ensures strength, stability, and precision. Whether you need a luxury pivot door, sliding barn door, or oversized feature, Sing Core delivers lasting value with low maintenance.

Need help choosing the best custom door skin? Contact Sing Core today!

 

Wood Stave Custom Door Skin

 

 

Wood stave uses solid wood strips glued together. This method highlights natural wood grain and works well for premium exterior doors.

Our 1/8″ (.125 inch) wood stave is better than 1/4″ (.25 inch). The thinner option is more stable but looks the same. Sing Core recommends 1/8″ for precision and less distortion.

For best results, keep each stave under 6 inches wide. Narrower staves reduce movement from moisture. Unlike solid wood, stave construction is stable and easy to fix. Repair with a handheld router or CNC shaper. Even forklift damage is repairable with Sing Core.

Wood stave suits interior and exterior doors. It works for pivot, hinge, and sliding doors. There’s no size limit, making it great for large doors. Costs are similar to or slightly higher than hot press veneer doors.

Hot Press Veneer Custom Door Skin

 

Hot press veneer bonds thin wood veneer (.020 to .032 inches) to a panel with heat and pressure. It creates a seamless, smooth finish with book-matched or slip-matched patterns.

It looks stunning but is delicate. Thin veneer scratches easily and damages from minor impacts. It’s best for interior use and not for exterior doors.

Hot press veneer doors are expensive, especially large ones over 5 feet by 10 feet. They offer a high-end look but need careful handling.

 

Cold Press Paperback Veneer Custom Door Skins

Cold press paperback veneer is a budget-friendly choice with a natural wood look. This method uses adhesive instead of heat. Pressure holds the veneer in place until the glue sets. It works with vacuum presses, contact cement, or cold press systems.

“Paperback” means the veneer has a paper backing for stability. Cold press veneer is the most affordable custom door skin.

However, it’s hard to repair if damaged. It’s best for low-impact interior use.

 

High-Pressure Laminate (HPL) Custom Door Skins

Wood grain-look High-Pressure Laminate (HPL) is tough and budget-friendly. It’s a great alternative to real wood.

HPL resists moisture, scratches, and wear better than wood. Its wood grain texture gives warmth and elegance without warping or fading. HPL doors are easy to clean, making them ideal for homes, offices, and commercial spaces.

HPL comes in many finishes, offering plenty of design options. It’s a durable, affordable custom door skin.

 

Wood Siding or Flooring (3/8″ – 3/4″) Custom Door Skins

Wood siding or flooring panels give a thick, solid wood look. These custom door skins add durability and a natural wood feel. They come in various hardwoods and softwoods for different designs.

Only use floating mechanical fasteners for this Custom Door skin, such as:

  • Keyhole fasteners
  • French cleats
  • Furring strips

Floating fasteners allow wood movement and prevent warping or cracking.

Unique Exterior Doors

Unique exterior door can be the detail which makes any project come to life. Certainly, the most impressive detail which leaves the most lasting impression are the unique front doors which are appearing in the most significant contemporary architecture and designs.

High end custom architectural doors are sprinkled throughout all the latest emerging structure designs as not only attention grabbing unique front doors but are included as a unique home designs security door which add to the appeal of the vast array of unique exterior doors appearing across the most modern architectural designs.

Leading the pack, are the designers who push the envelope of size and materials. While extremely large doors command the lion’s share of the most attention commanding performances, there are many kinds of unique front doors and another emerging technology includes the unique home designs security door, where Sing Core is playing an important part.

These doors may look unique at the surface level but far more unique goings on have taken place deep inside these doors, so what’s happening inside these doors is far more unique than was observable with the naked eye.

Inside the unique front door décor you will find inventor Peter Sing’s patented “Sing Core” along with other patent and patent-pending anti-warp technologies hard at work to keep these doors perfectly straight and true, regardless of what challenges they might face.

Whether you’re looking at individualized high security impact doors or unique storm doors, Sing’s core delivers not only warp-free door tech but also imbues these doors with other satisfying characteristics, such as being fully insulated to provide sound deadening and climate control. These are exciting features which can be found from installing a door with Sing Core inside.

UNIQUE CHARACTERISTICS

Your unique front doors can possess all these exciting attributes found inside the highest quality architectural doors across the nation and the world, just by having your architect specify Sing Core doors.

1. LIGHTWEIGHT

Sing’s patented core technology enables his factory to pump out solid hybrid door blanks which weigh in at a fraction of the weight of other wood-based solid core doors. Rivaling the weight of a hollow core door which has virtually no strength, tends to warp and is damaged easily, Sing’s substrate, while extremely lightweight is not weak. In fact, the strongest and straightest lightweight doors in the world, have Sing’s core inside.

 

2. HIGH STRENGTH

Talk about strength, Sing’s invention has allowed the biggest and best door companies, millworks, and custom door manufacturers to design and build enormous oversized large doors, that are lightweight (see above) and extremely strong. In fact, independently rated at 660+ PSI, Sing’s core is stronger than steel pound for pound, yet very lightweight. See inventor, Peter Sing, standing amidst a 13 ft. span of a one-inch panel with little or not deflection. Any other material would have crashed to the ground.

3. WARP-FREE

Among high-end, scientific, and military circles, Sing’s core is the only known method to build a lightweight warp-free door of any material known to man, especially if the door sis very large, or features a natural woodgrain material (which is the most notorious for moving in response to changes in the environment). That’s why you’ll find Sing’s core in use anywhere from beneath the sea (US Navy) to outer space (NASA) and anywhere in between. Sing is so successful at building warp-free doors and other products that he offers a 50-year warp-free guarantee.

4. HIGH PRECISION

While standard project allows for give and take of available building materials, such as AWI Standards’ allowance for ¼” variance at any time or location amidst a standard-sized door (7 ft. tall or less), Sing’s core hosts the highest tolerances (+/- .006 in.) enabling you to build high precision unique doors of any kind, whether made of wood, synthetics, or metals, even stainless steel.

 

5. FULLY INSULATED

While most end-users who seek out Sing’s core are looking for something lightweight that doesn’t warp to solve existing issues which have arisen in a current project, having a product to build such a door that is fully insulated offers a huge advantages, even if it wasn’t your primary focus when you first sought out the Sing Core solution to solve your door problems.

6. SOUND DEADENING

Whether for security reasons, studio separation, or just privacy and peace of mind, Sing’s sound deadening door core is the way to go when attempting to address issues related to sound transmission. Sing Core is routinely used in the manufacture of soundproof doors because it can bear the weight of dense and heavy sound proofing materials without fail.

 

7. CLIMATE CONTROL

Unique front doors can also offer smart climate correction which can be offered by a door which is fully insulated but still not be compromised by exposure to the elements. Sing’s patented climate control door core is used in refrigeration, heat and moisture exposed applications (like saunas) and can still outperform other available Eco-friendly lightweight building materials in side-by-side comparisons.

 

8. IMPACT RESISTANT

You don’t have to be in a high-security environment, a government or military facility to appreciate the added safety and security of having a unique front door with Sing core inside because a door should be more than just visual separation, you should be able to feel safe on your side of the door.

 

9. ECO-FRIENDLY AND SUSTAINABLE

Sing’s door substrates are manufacturing using the strictest Eco-friendly methods of manufacture. They are made with little energy, feature recycled materials, extremely responsible use of natural materials such as wood fiber and Sing uses formaldehyde-free adhesives, while producing no toxic material waste. Sing’s substrates have an extremely small carbon footprint even though they are shipped around the world because their transport costs less and consumes less fuel due to being so light weight.

That’s just a few of the reasons why more architects are specifying Sing Core inside their doors.

Paint Grade Doors

There are 2 of the most popular types of paintgrade options available for your architectural door specs from Sing Core, and each includes patented Sing technologies to maximize the potential of these formats, ensuring you can enjoy the only

50-year Warp-free Guarantee

Sing Core Paintgrade Door Blanks

Underlayment

The secret to creating an incredibly smooth paint grade door is what lays underneath the painted surface. At Sing Core, the True Flat Team is likely to suggest using a 1/8″ MDF over 1/4″ Plywood surface for the smoothest surface area. Another alternative would be  3/8″ Marine Plywood, which would require a preparatory priming prior to painting for a perfect paint job. Of course, your door will only remain straight for 50 years, if you have Sing Core technology inside.

WARP-FREE MDF (INTERIOR) WARP-FREE MARINE PLYWOOD (EXTERIOR)
  • Warp-free MDF is lighter in weight and stronger than other MDF.
  • Average 1.5-inch to 3-inch thick MDF paintable door blank weighs approximately 1.5 to 3 lbs.
  • The surface of MDF is very smooth which makes it great surface for painting.
  • MDF is very consistent throughout, so cut edges appear smooth and won’t have voids or splinters.
  • Because of the smooth edges, you can use a router to create decorative edges.
  • Warp-free MDF is excellent substrate for applying .020-inch wood veneer or other thin laminates. (see below)
  • Made from multiple layers of wood veneer, marine plywood is a strong wood fiber material.
  • Marine plywood is water resistant and good for use in exterior door applications.
  • Marine plywood face grain can be easily stained.
  • Marine plywood holds screws very tightly since the varying grains of wood on each layer give the screws something to hold onto.
  • Marine plywood is an excellent substrate for applying natural wood stave, wood planks, or other materials. (see below)

The most popular and least expensive is marine plywood.

Warp-free patented and patent pending Sing Core marine ply door substrate

Our marine ply is used in oversized exterior door applications and is constructed using water resistant adhesive using an A-grade veneer face, C-grade inner plies, and a B-grade back which is used for securing patented Sing Core. Marine plywood is a better grade of plywood, commonly used in cabinetry, where the backside need not be presentation quality.

The 16 ft tall door (above) is teak wood stave door for a mansion in Beverly Hills with Sing Core inside and can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

The A-grade is the highest quality veneer and most sheets will be free of flaws resulting in a plywood surface that is smooth and can be prepped and painted easily.

Warp-free MDF Guaranteed True Flat for 50 Years

The above picture shows MDF substrate ready for paint grade or laminating thin veneer. We work with millwork companies and high end door manufacturers to provide the most strong, lightweight, non-warping door with best guarantee in the USA.

Large barn sliding door with paint-grade 1/4″ marine ply skin.

Warp-free MDF

Sing Core’s MDF is not your father’s MDF. Inventor Peter Sing has developed a method or creating a perfectly smooth surface, which is a well-known characteristic of MDF, which is lightweight MDF and will not warp. Moving due to lack of strength, especially amidst long spans, is also a well-known characteristic of MDF.

Sing uses a combination of patented and patent-pending technologies which result in the only large warp-free MDF door blanks in the door industry. That’s why Sing Core is known for creating the highest grade MDF in the door industry.

When making big doors, like the large oversized doors which Sing Core is famous for, to try to use MDF without Sing Core inside would be like building a door with a giant noodle, granted the surface would still be smooth as can be.

Because MDF is not water resistant it is not recommended for exterior applications, so avoid specifying MDF for large entry doors due to its inherit weakness, instead spec marine plywood as your base material instead.

Due to the smoothest surface area material, MDF can easily be painted, or used as underlayment for thin veneers, vinyl, or other laminations.

The above doors are 16 ft. tall feature .o20 white oak veneer. Door substrate made of patented Sing core with MDF substrate for the tallest building in North America, on the 86th floor’s Sky Club atop the New York World Trade Center.

In fact, all the most high-end veneer-work done by Sing Core uses this warp-free MDF solution as underlayment for the perfect veneering for which they are known. See: How to Make the Best High-end Veneer Doors. Likewise, their high-end millworks and door companies who apply their own laminates, they order this material as their gold standard.

On the other hand, if your intention is to add natural wood planks, then marine plywood is preferred substrate, especially for exterior doors.

While marine plywood and MDF are the most popular there are many other skin types for plywood, paintgrade, and others.

Wide Front Door

You think your customer is asking for a wide front door when it’s 42 inches wide, but what about when your architect specs a door that is 25 ft. wide and 10 ft. tall? If 42 inches is a wide front door, then a 25 ft. wide slider would be considered an extra wide front door at the very least.

According to the millwork that installed a pair of these 25 ft. wide warp-free wire-brush-finished white oak extra wide doors, they weighed-in at “a couple hundred pounds apiece,” and like so many other millworks and door companies proclaim,

“We couldn’t do it without Sing Core.”

Sing Core is the place where contemporary architecture and design of the wide front door comes to life, and you will find wide front doors all over the most amazing locations throughout the USA and the world, even atop the highest building in the United States, the World Trade Center. And they just don’t come here for ideas and inspiration for their next wide front door, they’re looking for a way to make it happen. And by “make it happen” we mean,

How to build a wide front door that will not fail

We bring the visions of those modern architects and their architectural door creations to life in a way that will not embarrass them down the road (like at the next climate change), when doors will warp, twist, bend, cup, otherwise compromised or become completely inoperable.

 

There are optical illusions which make a front door look wider, such as adding sidelites on either side of the door which makes it look much wider, but the part of the door that opens, is a normal width door. What if that entire area articulated like one wide front door. That’s a solution provided by Sing Core that can be an option for you or your clients, such as the Sing Core Side Light Door. It’s quite impressive when the whole area, including the sidelights open with the door, moves when the door is opened or closed. This is a most impressive effect when used as a wide pivot door.

Another idea which is gaining traction in contemporary architecture is to use a wide pivot door but include an embedded man door which articulates via side hinge. Man door access doors get used for normal egress use and when you really want to impress your audience or guests, operate the pivot door and the whole front area pivots.

If wide doors were not wide enough, consider that modern architecture designs are adopting a double wide front door approach to standing out and making an artistic and attention-grabbing presentation with elegance for your extra wide exterior doors.

In this respect, when your wide doors have Sing Core inside, you can express full creative expression as virtually any custom contemporary wide front door could take on the look and feel of any artistic representation.

Your project, for instance, could feature an extremely wide front door made of nearly any available flat building materials, such as acrylic, aluminum, brass, copper, cold rolled steel, fiberglass, Formica, FRP, galvanized steel, HPL, hot rolled steel, Masonite, Stainless Steel, or any available natural wood species.

Of all these types of doors, normally, natural wood grains present the greatest number of challenges associated with warping, especially with wide front doors. Yet, if made with Sing Core inside, these doors can be guaranteed to remain

Warp-free for 50 Years

Only doors with Sing Core inside can be guaranteed not to warp, bend, twist, cup, or otherwise fail (including delamination) for 50 years.
It’s no surprise that you will find Sing Core beneath the sea (US Navy) in outer space (NASA) and everywhere in between, from coast to coast, though admittedly, more than 70 percent of all the wide front doors we ship, from our serene wilderness factory in the Pacific Northwest, ship to the greater New York area, mostly New York City. We lovingly refer to NYC as our sister-city.

DIY Side Sliding Garage Door

Because of this, we only sell to individuals with the skills and equipment to properly finish and hang our doors. If you are a homeowner without construction skills, we recommend that you contact a millwork or finish carpenter in your area, and tell them you want “SingCore inside”!

Because SingCore is exceptionally light, less than 1/3rd similar solid wood doors, they make great manual sliding garage doors. Easy to operate, highly insulated, and perfectly straight for your lifetime, SingCore siding doors are practically unparalleled on the custom garage door market.

Why Architects Spec Sing Core

Why Do Architects Spec Sing Core?

In order of importance:

The number one reason architects specify Sing Core is for oversized doors of all kinds.

1. 50 YEAR WARP-FREE GUARANTEE

Any door over seven ft. tall and three-and-a-half ft. wide is going to have a problem with warping. Having Sing Core inside is the only know way to make a lightweight, high-strength door that can be guaranteed not to warp and includes a full structure and lamination warranty for 50 years.

2. SKIN OPTIONS

Beauty is not only Skin Deep

If it’s an available flat surface material, Sing Core has the expertise to apply it to patented and patent pending Sing Core technology in a superior high precision manner which will not delaminate following proper finishing.

MOST POPULAR SKIN OPTIONS

A) WOOD VENEER

Wood veneer is the popular choice for use in architectural doors. Application of veneers in large door projects can be very tricky, and Sing Core utilizes the most advanced comprehensive lamination methods to laminate large veneer doors.

B) WOOD STAVE

Applying solid wood stave (natural wood grain planks) is the hardest material to feature on large doors due to the wood grain’s nature to shift and change in response to changes in the environment. It is hard enough to keep a standard sized wood plank door straight but building an oversized wood stave door is exponentially more problematic, unless it has Sing Core inside.

C) MDF

Sing Core has a unique method using their patented and patent-pending technologies to create the first super smooth high-precision MDF surface area that will not warp. This “smooth as glass” material is ready to paint, add vinyl graphics, or other materials such as veneers or wood stave via cold press in your own shop or millwork. Hot-press-ready version also available. We know how to do it. Just spec it and see for yourself.

D) STEEL

20G steel is the most popular grade of steel used on architectural steel doors with Sing Core inside. Why 20-gauge steel? Because even though Sing Core is lightweight it is stronger than steel pound for pound. That means you can use a lighter weight steel, without compromising the door’s integrity or visual appeal. Most popular steels are cold rolled steel, hot rolled steel, galvanized steel, stainless steel, and diamond plate steel, among others.

E) SYNTHETICS

The most popular synthetics used on architectural doors are FRP, Masonite, Formica, fiberglass, and acrylic. The lamination experts at Sing Core know exactly how to deal with these hybrid and synthetic materials to qualify them for their 50-year fail-free guarantee.

F) ALUMINUM

The less expensive yet durable metal skin, aluminum or aluminium is an excellent choice of architectural door skin, and as with steel and other metal doors skins, thinner is better due to the high precision and superior strength of Sing Core.

Note: All door skins have exponentially increased adhesion, as the surface area increases, so does the bonding agent, due to Sing Core’s true flat nature and high precision at +/- .006 in. tolerance. Other honeycomb cores, like aluminum core, is only +/- .03 tolerance, and has very minimal surface area for adhesion, whereas Sing Core is solid surface.

3. HIGH PRECISION SUBSTRATE

Sing Core is a high precision solid surface substrate material sporting .006 tolerances. It is this degree of precision which is necessary, along with extensive proprietary knowledge and patent-pending anti-warp materials, to create the high definition bonding which is necessary to join and two flat surfaces with unsurpassed results. This enables Sing Core to create laminated panels, posts and beams which are created to last for centuries without failure.

What happens if you don’t specify Sing Core inside your doors?

IF YOU DON’T SPECIFY SING CORE inside your door, you are likely to get a heavy LVL door core, or if you specify “lightweight” you are likely to get an aluminum honeycomb door, which may look good on the outside and may hold up following installation, but not for long. Low tolerance (+/- .03 in.) and tendency to move are just too much of a sacrifice to make for discerning clients, like those who are increasingly looking to Sing Core to solve the problems associated with large oversized doors.

4. FULLY INSULATED

This is an added benefit enjoyed by contemporary architects who specify Sing Core inside their modern doors, but for those in search of insulated doors, this patented and fully insulated substrate is the only way to achieve lightweight high strength and superior insulation throughout for sound deadening and increased climate control.
