Door Finishes

There are many ways to build large doors with Sing Core inside, the only doors that can be,

Guaranteed Warp-free for 50 Years


When it comes to oversize doors, one door stands out above the rest for high-end applications; see comparison. Look for these features in your door for the most discriminating taste(s):

  • Available in any size (up to 16 ft.)
  • Lightweight
  • Strong (stronger than steel pound for pound)
  • Insulated
  • Sound-deadening
  • Guaranteed True Flat
  • Resistant to warp, twist, crack & rot
  • Standard 10-year warranty
  • Professional 50-year warp-free guarantee

For more detailed information on our doors, see our Architectural Specifications.

Though Sing Core Doors are available in nearly any wood species, our standard varieties include:

sing-maple sing-cherry sing-oak sing-vg-fir sing-walnut
MAPLE CHERRY OAK VG FIR WALNUT

Note: Door designs can be modified to meet your specifications and requirements an may include the application and bonding of any flat building material. Please feel free to inquire for more information.

1. Paint Grade Door

2. Wood Grain and Wood Stave Door

3. Hardwood Plywood Door

1 Paint Grade Door

Our most popular door blanks are paint grade, and can be made to your specs including surface materials of,

  • Birch ply (most common)
  • Wood plywood
  • MDO
  • HPL
  • Other material, as specified

 

2 Wood Grain and Wood Stave Door

Besides paint grade for the surface, we also provide solid wood stave laminate on both sides of the sliding door. Wood stave is easy to work with and will last. Your Sing wood stave door will be more high precision than solid wood door (less warping, and twist and crack) due to Sing Core’s extremely high tolerance (+/- .006 inch) and, rigidity and high strength (660+ PSI) and professional grade wood grain and wood stave doors are certified and guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

Sing Core provides hot-press ready door blanks to door manufacturers who add wood veneer on both sides of Sing door blanks which are made of Luan skin or marine grade plywood sandwich with patented Sing Core in the middle, solid wood around 4 edges and wood block implants where needed for hardware.

oversize-panel-edge-glued-together-planks-5ftx10ft Sing-Hardwood-Panels-Variety

Note: Veneer has to be handled very carefully every step of the way during production (we prefer to let the millworks handle this delicate procedure) and it is easy to damage by users over the years (but wood stave can be easily sanded and repaired).

We offer a very good price for wood stave doors, the cost is not much more than wood veneer doors.

3 Hardwood Plywood Door

We could make door with hardwood plywood as an effective way to make super large doors that you can stain any color. Up to 4×8 doors have no seam, but by orienting the grain horizontally, you can achieve a nearly seamless presentation on really big doors or extraordinary size.

Available in any available wood species, most common are Sapele, Oak, and Maple ply.

Sing Hardwood ply door has excellent strength, yet is lightweight, features good insulation and better sound deadening qualities than solid wood plank doors.

What We Do

What We Do and What We Do Not Do

We get so many inquiries about people who want Sing Core, we thought it might be helpful to help you better find ways to get Sing Core into your hands. With that in mind, let us tell you a little more about what we do and what we don’t do.

The Only 50 Year Warp-free Guarantee and full structure warranty

What We Do

We do the job that no one else can do. We do not do the work that is better left to more qualified and skilled trade professionals. The reason our clients seek us out is to perform the parts of the job that would not be possible without the use of patented Sing Core. It is the unique combination of what we do best and what the experienced trade professionals do best that results in creating the best if the best, highest quality end products possible.

We have solved the age old problem of warping doors, high end large doors that are lightweight yet extremely strong with the best warranty in the high end door industry. This same invention helps other industries meet or exceed the high expectations or requirements of their most demanding clients.

Sing Core is a patented solid torsion box hybrid core that is lightweight and high strength. We have developed and manufacture this revolutionary building material here in our Pacific Northwest factory. Part of our manufacturing process includes laminating flat exterior surfaces, or skins, to our proprietary core. Our clients often trust our lamination expertise and request our adhering additional flat building materials to the faces and edges, though many of the manufacturers whom we supply apply their own materials to the surface areas of our Sing panel.

We do offer custom interior blocking inserts, custom channeling for utility and wire chases, as well as custom lite cutouts for glass installation per architectural specifications.

We build the biggest lightweight high-strength panels, which can be built as giant slabs (subject to transportation limitations), large oversized doors, or as modular components to be shipped to and assembled on site.

We build to architectural specification only. We only ship to millworks, door companies, custom door builders and manufacturers of almost anything from furniture to bridges and aircraft.

We do build high performance sustainable Sing products with the flattest, straightest, lightweight high-strength material available (Sing Core) with the highest tolerance (+/- .006 in.).

We do participate with architects and engineers on the specifications of products which are built for specific applications for a guaranteed life-span (i.e., 50-year warp-free guarantee) to make certain the Sing product meets or exceeds high performance expectations.

We manufacture all Sing products in our factory in McCleary, Washington, assuring every item is proudly made in the USA.

We ship Sing products directly from our factory to our customers in the United States all over the world.

What We Do Not Do

While we can do a great many things, we leave certain areas of expertise to the industry professionals whom we supply with patented Sing Core products. That said, we do not build any finished product. While we are renowned for the most magnificent large doors built, and the only Eco-friendly lightweight high strength doors in the world, we do not build doors. These luxurious doors are finished by find crafts people who have the highest level of skill and competence which makes our product so beautiful.

We do not do any finishing of any Sing product(s) or build any finished Sing products.

We do not engineer, certify or have any stamped or code-approved stock items. For instance, we do not sell fire-rated doors, even though we build doors to engineer approved fire-rated specifications, which are rated, approved and/or stamped, but this is done by the door companies or other clients.

Likewise, we do not build sound-rated doors, even though we have built doors to architectural specifications which are used and may be rated as acoustical doors and sound proof walls (we even have a local sound testing and rating laboratory nearby, which may be used at customer’s expense). We supply the best door panels for door manufacturers and millwork to meet their client’s demands such as fire rating, sound proof, even bullet proof, etc…

We do not install glass in Sing products, although we can custom pre-cut and/or frame for lite cutouts, which are ready for glass installation by the company responsible for finishing the product.

We do not have stock items, with very few exceptions (i.e., trade show panels) and we do not ship to residences unless it is a job site being managed by our wholesale-approved client.

We do not sell retail. We are licensed only for wholesale and do not ship Sing products to anyone who is not in the business and qualified to expertly finish and ensure proper installation of Sing products.

What We Love

We love helping our architecturally advanced clients enjoy the most prestigious, high end Eco-friendly lightweight high-strength insulated products, panels, posts and beams, and doors that can be guaranteed not to warp for 50 years.

Sing Panels with Plumbing and Wire Chase

sing-panel-horizontal-embedded-cable-chase-wire-chase-plumbing-chaseCustom Sing Panels can be manufactured to your architectural specifications which may include special chases for plumbers to route hot and cold water feeds via plumbing or electricians to run electrical wiring, communications and security through a patented Sing panel.

Surface mount conduit and exterior chases can be added to Sing panels as they are, though many users of our patented insulation reinforced torsion box core prefer to use embedded wiring chase of for water supply pre-installed plumbing chase.

Embedded Chases

Embedded chases can be placed at specified locations prior to manufacturing your Sing panel to meet the specific requirement of the job at hand, accommodating communications center needs or the special needs of inplant offices, clean rooms, temporary warehousing, watch towers, guard shacks, portable classrooms, spa expansions, home theaters or any application where running utilities, like electricity, wiring and/or cables or plumbing inside and through your Sing panel may be advantageous.

Common horizontal chases are specified at 16 inches and 45 inches from the base, while the most common location for a vertical chase is in the center of the Sing panel. Regardless, every Sing panel is custom manufactured in our factory, and we can have your wire chase or plumbing pre-installed within your panels at any location specified.

How to Specify Wire Chase Locations

sing-panel-embedded-cable-chase-wire-chase-plumbing-chaseIt is easy to have your embedded chases pre-installed at the proper locations. All you have to do is to be certain to disclose the precise locations and sizes of your wire chase (plumbing chase or cable chase). We will provide you with an architectural drawing of your panel before your custom Sing panel is built for you to confirm the chase’s location.

No Loss of R Value

To preserve the R-value of your Sing panel it is advisable to have the cable chase filled with spray foam insulation after pulling the wires or routing the plumbing through the embedded channels. Likewise, if a channel is not used, it should also be filled with foam insulation prior to final assembly, unless insulation properties are not necessary for your application.

Panel Chase Options

Although many options abound for electricians and plumbers to install access to services, another popular method includes running cable, wire and plumbing through panel connectors that run the length of your standard Sing panels, or alternatively running services through the floor.

Many creative options are available for adding access to water, electricity and communications without having the necessity of pre-installed chases being embedded in your Sing panels.

Economy Chase Options

An emerging value-minded approach to inexpensive reinforced structural insulated panels is to obtain two economy 1.5 inch Sing Panels from your local Lowe’s Pro Desk. Prior to gluing them together to make a single 3 inch panel, simply router out where you want your chase channel to be, then adhere the two panels together. This is an inexpensive option discovered by price conscious tiny house builders.

Strength Performance: Patented Sing Core has an unsurpassed strength as compared to other lightweight substrate materials tested at 660 PSI (based on 2″ x 2″ grids and 3/4″ thick) for superior structural integrity and is resistant to warp, twist and crack when compared to other materials.

Light Weight Performance: Sing Core weighs much less than other traditional building materials, as much as 50% less; or more, as little as 4 lbs. per sq. ft. yet sustainable and true green technology.

Insulation Performance: Standard Sing Core door pivot blanks feature built-in insulation value with an R3 (can be upgraded to to R6.5 or more) rating per inch, depending on architect’s specifications.

Acoustical Performance: Sing Core standard pivot door blanks have a natural sound-deadening quality for noise control. Standard sound transmission class (STC) is 30. Additional noise control specifications can be met at the behest of the customer or designer and must be noted in advance.

Eco-friendly: Sing Core is manufactured using natural wood fibers, no formaldehyde, or toxic chemicals, is created using less energy than any other core material with little or no waste. The structure of Sing Core is 100% renewable (nature-grown) clean wood fiber and/or recycled material.

Warranty: Sing Core pivot door blanks come with a 10-year warranty, while professional manufactured pivot door blanks can be structurally guaranteed and warp-free for 50 years under normal conditions.

Large Cold Rolled Steel Door Modular Assembly Specifications

General Specifications

 

Standard Sing Core Cold Rolled Steel Door Blanks are manufactured with patented Sing Core material as the base interior substrate of the door. The Sing Core substrate material is created using a vertical grain natural wood torsion box design while the traditionally empty voids are filled wall to wall with recycled foam. The foam material is available in various forms depending on your specification. The default is recycled EPS foam. Natural wood lock blocks can be positioned at locations as necessary for locking mechanism placement or as anchor points. The core material is framed by 1.25-inch wood stiles and rails for finishing strength and attaching hardware. The torsion box is completed by adhering 16 gauge cold rolled steel as exterior material (skin) according to your specifications.

Cold Rolled Steel Door Surface Material

The door blank surface material is made of 16 gauge cold rolled steel unless otherwise specified. Bonding agent used in adhesion of the entire composite material is formaldehyde-free.

Every Sing Core manufactured door blank is unfinished (unless specified otherwise) and professional grade is guaranteed for 50 years for warp-free and structural integrity.

Detailed Specifications:

Scope: Subject to local building codes, the standard Sing Core door blank is intended for use in:

  • Single family dwelling interior applications
  • Multifamily dwelling, low-rise professional office, library and low-rise motel interior applications
  • Lighter use industrial building and factory, hotel and retail sales building interior applications

 

Cold Rolled Steel Door Materials: Sing Core cold rolled steel door blanks are manufactured using Eco-friendly cold-press process. Composite materials include:

  • Sing Core vertical wood-grain torsion substrate filled with recycled EPS foam
  • Core material is framed with solid wood stiles and rails
  • Facings are 16 gauge cold rolled steel
  • Formaldehyde-free bonding agent is used for adhesion of all components

Large Door Component Assembly: The largest doors (see 10×10 example drawing tot he right) may not be easily transported from the factory to the job site. In cases such as these doors are divided into two or more modular components and joined together on site using patented Sing biscuit joining method. This method results in a near seamless joining of two or more door blanks without compromising flatness or structural integrity.
