Custom size and thickness available at almost all sizes and thicknesses. We are experts in manufacturing true flat panels and non-warping panels for very large doors, walls, tables and more…
Professional panels are made of a wood torsion box grid with foam inserts, professional stiffeners, a solid wood frame with blocking for hardware, and two matching skins “sandwiching” the core.
Build your own non-warp door without the extended delivery time
The Professional Sing Panel takes the standard Sing Panel to a new level of high precision and increased performance. The Standard Professional Sing Panel comes in standard 4 ft. x 8 ft. x 1.5 in. size with 1.5 in. solid wood edges that can be cut, ripped or sawn into any shape, size or thickness in your wood working shop (no special tools required). If you remove solid wood to create your idea target size, all you need is router the core on the open side and glue back a piece of solid wood to build the size of panel in your shop without any extended wait time… On demand, in your warehouse when you need it.
|Standard skin = 1/4 in. lightweight plywood Option = Marine-grade plywood Includes 1.5 in. solid wood edges.|
Standard Professional Sing Panels are specially reinforced for increased performance by our team of experienced professionals with an acute sense of composite technologies to create a professional panel that will have the structural integrity to far exceed performance standards deemed “acceptable” by the trade industry.
The Professional Sing Panel is available only to trade professionals, includes embedded stiffeners and is cold-press-ready or available as paint grade or with natural wood stave surfaces. Click here to see skin options. For Hot-press-ready see Hot-Press-Ready Sing Panel.
Professional Non-Warp Door Blanks
Professional Sing Panels are also available in a variety of standard sizes for Guaranteed Non-warp Door Blanks. Using patented Professional Sing Door Blanks, any door can be made in any style of any material in any size that can be guaranteed to be true flat (well above AIA standards for flatness) and not to warp for 50 years including structure guarantee when used for intended purposes for which the door was designed.
The largest door manufacturer in the East Coast has been struggling with the challenge of building large oversize doors.
The Problem: Not long after installation, the doors will warp.
The Solution: Using Sing Guaranteed Non-warp Door Blanks this door manufacturer can now make non-warping doors to meet any specifications.
Details: Originally, the East Coast door manufacturer purchased custom door blanks as needed to fill the need as it arises; then opted to order a stock of standard-sized Professional Sing Panels to keep in stock for building their own non-warping door cores on demand. Standard stocked sizes are 4 x 8, 4 x 10, 4 x 12, 5 x 8, 5 x 10 and 5 x 12. Manufacturer reports ease of cutting to size, routing and inserting wood stiles or rails to specs.
Available with all the options available in the classic Sing Panel, the Custom Professional edition has even more strength, integrity and ability to span distances with little or no support and little if any whatsoever.
Custom Professional Sing Panels are available in any size, any thickness i.e., large oversize panels or planks, posts and beams, with any of the following custom options.

WINDOW AND DOOR CUTOFFS
Sing Core provides Sing panels with window and door pre-cut and ready for installation. We will cut 1/8 larger in width and 3/16 inch wider in length to fit your window glass. We build a frame using 1.25 inch solid wood to your specifications.
Sing Core windows and doors are profile ready for CNC routing. You may add molding or trim to create your own window or door design, otherwise we will provide you with thicker skin – such as 1/4 inch or thicker MDF, hardboard, etc. – for you to carve or profile by CNC machine. With Sing Core windows and doors you can create a true raised-panel door or any design you desire.
TRIMMED OR UNTRIMMED (RAW EDGES)
The standard ready-to-ship panel condition is, “untrimmed.” This leaves unfinished exterior edges that may have exposed adhesive and might require being built ½ inch over-sized for trimming at your location. An additional fee will be assessed for trimming and sizing in our factory.
All trimmed edges are 1/2 inch over width and 1/2 inch over length. After trimming, your Sing Panel will be 1/2 inch less (4 x 8 will be 47.5 inch x 95.5 inch). Standard solid wood edging with 1.5 inch will be reduced to 1.25 inch after trimming.
UNTRIMMED PANEL (RAW)
Many of our customers prefer their panels untrimmed because this allows them to trim their panels to exact size on site before installing them in their door openings. That way they can have the peace of mind that their door will fit the opening exactly as intended.
Customers who want their panels cut to exact size before they receive them should choose the trimmed selection. This gives them the option of doing less work on site, but it also means they must be much more precise with their measurements before ordering their panels. Trimmed also costs slightly more because it is more labor intensive to trim the panels in house.
BLOCKING FOR HARDWARE
Sing Core panels can be used with any hardware that is rated for the weight of the panel. Solid wood blocking is placed in your specified locations to accommodate your hardware. How to specify your blocking for hardware.
- R-value 3.5 (EPS foam)
- R-value 5.7 (urethane foam)
Sing Core panels weigh only 4 to 5 pounds per cubic foot depending on your skin choice.
Our 1-inch small grade panels have been tested to reach 660 psi.
Sing Products come with a limited lifetime guarantee. (See Warranty Information)
Professional Sing Panels commonly have a solid wood edge (1.25 inch is standard, any custom size is available).
Professional patented Sing Core creates the best non-warp, lightweight, high strength panel material for superior construction with embedded professional stiffeners.
If you are an architect, general contractor or millwork and expect a non-warp guarantee from the door manufacturers (especially the very large and expensive doors) you would be very hard-pressed to come to an adequate warranty arrangement with either a door manufacturer or millwork because large doors and doors made of exotic woods are prone to fail; that is, unless the door is made with Professional Sing Panel inside. This is how we help to make the best doors in the world that can be guaranteed for structure strength and not to warp for 50 years.
In the event one side is exposed to excessive moisture or temperature then it could cause warping if the panel is very thin. If you have high expectations for non warping (which most of the high end large doors have problems with) Professional Sing Panels are the only insulated panels that warp less than any known core material. All Sing customers are happy with what we deliver when using the Professional Sing Panel to build their non-warping doors; which is changing the previously known idea that all the large doors in North America warp due to the change of seasons. The secret inside the best non-warping doors is the Professional Sing Core which keeps the Professional Sing Panel flat from our factory to its destination and stay flat for 50 years with structural integrity guaranteed.
A Professional Sing Panel consists of a substrate of patented Sing Core torsion box reinforced insulated core with special patent pending Sing stiffeners sandwiched between two ¼ inch sheets of plywood, resulting in the most Eco-friendly lightweight and high-strength (660 PSI, stronger than steel pound-for-pound) non-warp material. The Professional Sing Panel is the basis of many applications spanning a multitude of industries.
