Architectural Flush Wood Door

Working hand in hand with architects, door engineers, designers, millwork shops, and custom door manufacturers is everyday life at SingCore, nestled in the Pacific Northwest. This is where architectural flush wood doors move from idea to reality.

Yes, architecturally inspired flush doors can be purchased off the shelf. But an authentic architectural flush wood door is something entirely different. It is purpose-designed, custom-engineered, and created for a specific place. It carries intent, proportion, and material choices that cannot be replicated by standard production doors.

An architectural flush wood door may be one of a kind, or it may be part of a larger vision requiring hundreds of perfectly matched doors. Either way, each door is made for its environment, tied directly to the architecture it serves, and unmistakably specific to that project.

Architectural doors are functional art. Much like artwork on a wall, reproductions exist, but they lack the depth, precision, and presence of an original. To a trained eye, the difference is immediate.

Some clients simply won’t accept anything less than the original.

Architectural flush wood doors are comprised of many materials combined in unique ways to create a unique door that is unlike any other. An architectural door designer might mix different wood grains in a unique design pattern on the flush door’s surface to create such an individual work of art.

The architectural door artist may also combine different materials into the door’s design, such as, wood, metal, and glass. Other materials, such as aluminum, brick, cement, copper, fiberglass, hot rolled steel, laminates of all varieties, plastics, and stainless steel, just to name a few of the most popular.

The best architectural flush wood door is a composite of many materials, and nobody know the intricacies of precision bonding many different materials together, all working in unison of the whole, all the (and here’s the kicker) while,

Remaining Perfectly Straight for 50 Years

than inventor, Peter Sing, who provides his patented and patent-pending architectural flush wood door technologies which are revolutionizing the way architectural doors are made.

The biggest and best architectural wood doors are large oversized flush architectural grade commercial doors, that can be very large, up to 50 ft tall or wide. (That’s a big door.) As you may have guessed, especially if you have some experience with any doors which are oversized, that keeping it straight is going to be a problem.

 

Any large door, over 7 ft tall or three-and-a-half ft wide, is going to present a problem with moving over time and the problems are exponentially worse if you’re dealing with a natural wood grain door. Due to the nature of natural wood, it expands and contracts in accordance with changes in the environment which results in the door warping, bending, twisting, or cupping.

Left to its own devices, such a large door will be problematic for the end user, requiring regular maintenance to deal with its propensity to move. That is, unless it has

Sing Core Inside

Patented Sing Core enables all the greatest door companies in the world to build enormous doors which will remain warp-free, even if they are constructed of natural wood species.

Of course, contemporary architecture and modern designers have resorted to using non-natural faux wood grain materials such as HPL to prevent the warping of architectural flush wood doors, but even so, those incredibly large doors still presented a problem with staying straight.

SingCore’s patented and patent-pending warp-free door solutions along with the years of technical expertise of his True Flat Team, can help create high precisions architectural doors results unsurpassed by any previously available door-building technologies.

These new leading-edge door manufacturing processes and anti-warp materials are able to produce doors of any size, made of any flat building material (yes, even natural woods) which can be covered by Sing’s unprecedented,

50-year Warp-free Guarantee

All SingCore’s premium flush wood doors are covered by a 50-year guarantee which covers any movement, as doors made with these technologies with not warp, bend, twist, cup, or otherwise fail (including structure and delamination) for 50 years.

No other company can offer such a guarantee on an Eco-friendly, lightweight, high-strength wooden flush door.

Added Architectural Benefits

Besides being warp-free and having the best and most long-lasting guarantee in the world, architectural doors that have sing Core inside also have many other extraordinary characteristics, such as

1. Lightweight

Architectural doors made with Sing Core inside are 1/3 the weight of other solid core doors manufactured with wood-based door cores. Creating doors so light in weight is extremely advantageous in reducing transportation and installation costs, as well as reducing the expense of heavy-duty architectural door hardware which is based on the weight of the door. A lighter weight door also translates to reduced maintenance costs related to regular door operation which if the door is heavier will increase stress and strain on both the structure and its hardware over time.

2. High Strength

No other Eco-friendly, lightweight door is stronger than an architectural door with Sing Core inside as these are the only doors which are stronger than steel pound for pound, independently architecturally rated by University at 660+PSI (many times stronger than commercial honeycombs used in aerospace at 10 to 110 PSI), making them the most sustainable doors known to man on planet Earth.

3. Fully Insulated

Even if your primary interest is having an architectural wood door that is straight and true, you might be pleasantly surprised that these are fully insulated for climate control (R 3.5 – R 6.5, or more, depending on architectural specs) and sport impressive sound deadening capabilities. It is not uncommon to find Sing Core inside the best soundproof doors in the most exclusive locations around the world in sound-controlled environments.

4. Solid

 

You should think about specifying Sing Core inside all your important architectural door projects.

AB Ply or MDF Paintgrade

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

WARP-FREE AB PLYWOOD WARP-FREE MDF
  • Made from multiple layers of wood veneer, AB plywood is a strong wood fiber material.
  • AB plywood is water resistant and good for use in exterior door applications.
  • AB plywood face grain can be easily stained.
  • AB plywood holds screws very tightly since the varying grains of wood on each layer give the screws something to hold onto.
  • AB plywood is an excellent substrate for applying natural wood stave, wood planks, or other materials.
  • Warp-free MDF is lighter in weight and stronger than other MDF.
  • 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 veneers or other thin laminates.

The most popular and least expensive is AB Ply.

Warp-free AB Ply

Our AB 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. AB plywood, is a better grade of plywood, commonly used in cabinetry, where the backside need not be presentation quality.

Only AB plywood door blanks with Sing Core inside can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

Generally, “AB” designation means that it will be free of knots in their outer layers, though color variations and a few healthy intergrown knots may occur infrequently. If there are any pin knots, they would only a few mm in diameter.

The A refers to the best side which is a furniture grade veneer and B the opposite side. Plywoods with grades A and B are used for finishing purposes.

The A-grade side 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

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 AB 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.

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 AB plywood is preferred substrate, especially for exterior doors.

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