Our panels make doors!
Patented Sing Core solid wood stave door blanks feature the newest technology in the door industry for composite doors yielding the only eco-friendly, lightweight, fully insulated, high-strength doors with wood blanks of any size (up to 40 ft.) that can be guaranteed true flat and to stay flat for 50 years.
Large door versus regular-size door challenge (i.e., over 4 feet wide and over 8 feet in length):
Large doors are heavy, dimensionally unstable, require more strength due to the heavy weight, and are a challenge to manufacture, ship and install. High-end jobs require precision and true flatness to please the customer. A homeowner’s architect, general contractor and mill worker must solve the problem of warping doors. The solution to the challenge is to use patented premium true flat Sing panels to make your doors.
Sing Core wood stave door planks are the only solid wood doors that will not warp, bend, twist or cup following installation. This means no more continuous service calls for maintenance of big doors that cannot possibly stay straight due to the limitations of solid wood – or any other door core – that is subject to failure. Sing panels have a patented honeycomb/torsion box interior which gives lightweight yet unsurpassed strength (pound-per-pound stronger than steel) and stability to any door, and allows Sing Core to provide a 50-year guarantee
Sing panels make amazing designer doors in any style. With Sing panels, fragile doors such as French doors are made lightweight yet strong, not warping or breaking hinges, which will last for many decades.
Sing panels make sturdy exterior doors in any style. With Sing panels, exterior doors are lightweight and strong, even when oversized. Our premium doors are guaranteed to stay true flat and not warp or twist for 50 years
The problem is that all door core materials are either not high precision, too heavy or will move when exposed to moisture, humidity or change in temperature resulting in door failure.
Heavy solid metal or steel will not warp, bend or twist, but is not high precision due to welding (sing core tolerance is + or – .006 inch!) and is often impractical due to the overweight issues causing excess strain on both the hardware and structure, causing continued maintenance issues. The solution is our patented lightweight yet strong Sing core technology.
Finishing a door blank:
There are two types of finish for door blanks: paint grade and wood grain. Paint grade includes such finishes as metal, MDF, marine plywood, etc. Wood grain finish includes such finish as solid wood stave and thin veneer.
This massive walnut door is designed with our special process to appear like a door made with one huge piece of solid walnut. Clocking in at a whopping 11.5 feet tall and more than four feet wide, the door weighs a mere 177 pounds, ensuring very little stress on your hardware and mounting points. This will guarantee your door will stay straight, strong, and functional over the long haul. SingCore is the home of the 50 year door!
Why Use Solid Wood Instead of Veneer?
Never settle for substandard veneer doors again. Door engineers prefer to use inexpensive veneer as opposed to real solid wood facings because veneer is thought to be less likely to warp, bend or twist. But thanks to the super-strength of patented Sing Core technology, you can use solid wood stave and wood blanks with confidence knowing that your door can be guaranteed true flat and will stay flat.
How can a solid wood-faced door stay true flat? As every woodworker knows, when using a solid wood surface, the grain will move according to moisture or temperature change causing the door to fail. When using our patented Sing Core as a substrate you can safely use solid wood because the solid torsion box/honeycomb patented material is continually keeping the wood grain straight and true. Whereas traditional wood stave doors contain a much greater proportion of wood fiber content, thus have a high probability of warping than thin veneer due to the imbalance of moisture content on each face of the door, patented and patent pending Sing technology solves this problem by combining stiffeners with patented Sing core on the interior of our doors. This Sing panel technology eliminates the troublesome movement of the door blank — warping is no longer a concern when wood stave is applied to patented Sing core.
In addition, solid wood is easy to work with, install (no need to hot press), repair and remodel. That’s why professionals trust Sing Core’s years of expertise in helping to design the only wood stave doors (that look just like solid wood doors) that can stay straight and true for many decades while respectfully honoring the beauty and elegance of solid wood, which far outlasts easily-damaged veneers, yet can be sanded and repaired if necessary.
Celebrate your real wood!
Our Eco-friendly lightweight, high strength alternative is the best solution for combating the issues associated with weight and size, especially large doors. Only our patented Sing torsion box/foam composite core combined with our years of experience provides guaranteed solutions for oversize doors.
That’s why this technology is found everywhere, from beneath the sea (US Navy) to outer space (NASA) and everywhere in-between.
Sing panels may be finished in almost any wood species, like mahogany, redwood, teak wood, cherry wood, walnut wood, cedar wood, Ipe wood, sapele wood, poplar wood, ebony wood, ash wood, oak or any other hardwood or exotic wood types available.
This same wood blank composite technology is also a common solution for high-end projects like engineered hardwood flooring, shiplap, wood furniture, wood shelves, decking, shed doors or any other application demanding high precision and exemplary performance over time.
Domestic Wood Grain Plywood
As an alternative to wood stave, domestic wood grain plywood could be used to create a nice wood grain surface, even for large sized applications.
Large veneer doors are built for the upper echelon of society, even reaching the top floor of One World Trade Center, the tallest building in New York. These huge white oak veneer doors measure 16 feet tall!
How is wood stave/veneer applied to Sing panels?
Wood Stave vs. Wood Ply
Wood stave doors are among the most premium doors of all doors on the market. Typically they are made with the highest quality hard woods, like Mahogany, Oak, Walnut, Maple, Alder, Cherry, and Teak. Despite the many benefits, wood stave doors can be very costly to make, especially if you’re looking for a lightweight high strength solution for a warp-free guarantee for 50 years. Using Sing Core inside your wood stave door featuring wood planks from 1/8-inch to 1/4-inch will create more potential for warp due to the nature of natural wood grain. This is the beauty of the more economical wood ply option for building your wood door. Wood ply is far less expensive and has alternating grain orientation which also helps to keep the door straight. Wood plywood is just like any other plywood except for its featuring a particular wood grain predominantly on the surface, and it offers far more strength and repairability over time than a less expensive wood veneer.
So, if you’re looking to attain similar visual results of a solid wood door at a fraction of a price you might consider having Sing Core inside your wood plywood door. Be certain to specify what type of natural wood plywood your want, if it is available, you can save thousands of dollars on your beautiful wood door. The most popular wood plywood features woods such as white oak plywood, maple plywood, oak plywood, mahogany plywood, walnut plywood, Douglas fir plywood, knotty pine plywood, and birch plywood just to name a few.
Note: the seam is tight but still slightly visible when joining two pieces of domestic plywood together to create a large panel.
