We offer our services to support door manufacturers in building stronger, lightweight, high precision and warp-free (AWI warp standard) insulated doors using our patented and patent pending Sing Door Blanks and Sing Stile and Rail frames.

Sing Core’s specialty is assisting to create incredibly large and extremely wide door panels which door manufacturers can utilize to build the most challenging high-end doors.

Large Quantity Production Runs

We can also assist in the high-quantity production runs for doors using our facility to pre-build base doors which might otherwise create a bottleneck for common door manufacturers. We love taking over the assembly line bulk of your large door orders with rapid turnaround times.

You choose your method of building your Sing Core door blanks:

1. Sing Door Core Panel

You specify the length, the width, and thickness of your Sing door blank, built to your specifications. You determine the insulation value and skin material, and we do the rest. The Sing door core panel method is the strongest and best Eco-friendly insulated door solution for any sized door, even large oversized wooden doors, available in almost any style.

2. Stile and Rail Door Frame

For our customers and their clients who prefer the standard design of stile and rail doors, we provide the manufacture of a stile and rail formatted frame made of any combination of Sing panel, post and beam configurations to create the most sustainable stile and rail doors, which are finished by only the best millworks and custom door manufacturers. Sing Core provides the most significant improvement to stile and rail technology (besides automation) in the last 100 years to create the strongest, lightweight, most high-precision, and warp-free performance in the history of the door industry.

Doors of Almost Any Style Could be Made with Sing Core Inside

1. Pivot Doors

Pivot doors are the highest and best use of Sing Core because for the most part, pivot doors are quite large in size and are often much thicker than a standard door. If your intention is to feature a real wood finish, you know you’re going to be in trouble, that’s when the warp-free attributes of patented Sing Core shines through as the only way to build a large wood door which can be guaranteed to offer warp-free performance over time: 50 years, guaranteed, on professional grade doors.

2. Sliding Doors / Pocket Doors

Sliding Doors often present problems when they are very large due to their sensitivity and tendency to move, bend, or cup in response to changes in the environment, for which Sing Core is the perfect solution.

Large bypass sliding doors are likely to deface, scar, or otherwise damage themselves if they are not kept straight and true by being built with Sing Core inside in advance of bypass door failure.

Pocket doors, which are the most problematic of all sliding doors, because they hide within a cavity are highly benefited from being built with Sing Core inside. If warped, the finish of the door may be compromised as it brushes against the frame or cavity’s interior, and if it cups or bends too far, may become lodged either inside or outside of the pocket unable to open and close as a door. Sing Core keeps them straight and true.

3. Hinged Doors

Hinged doors are for the most part manageable even when facing a certain degree of warp, which is normal in normal sized doors. Problems arise when doors are very large, especially if over 7 ft. tall or 3.5 ft. wide. Any movement or change in the door’s being compromised is increased exponentially in relation to the dimensions of the door. Not a problem with Sing Core’s professional door blanks.

Diverse types of hinged doors, such as French doors, sliding folding doors, front entry doors, and carriage doors (among other types of hinged doors), all present varying challenges when migrating from the drawing board to the real world, and Sing Core makes the difference.

Door Sizes

While Eco-friendly insulated Sing door blanks could be used in doors of any size, the efficacy is maximized in door performance in any door over 7 ft. tall and 3.5 ft. wide. This is why you find Sing Core inside the largest doors in high-end homes, businesses, and industrial sites, because it’s the only way to build a large door which can remain straight and true, regardless of the size of the door, while still remaining lightweight.

Door Shapes

Since every door slab manufactured by Sing Core is likened unto a one-of-a-kind piece of art, architects and designers are free to create a door of any size and shape using any available flat building material.

Sing door slabs can be created to accommodate any shaped design in any thickness, and so it goes for any shaped light cutout for glass openings.

Skin Options

Sing door slabs are available in almost any skin you want, limited only by flatness (surface material must be flat), ability to be laminated, and availability.

Some examples include, paint grade plywood, aluminum, brass, cement board, cold rolled steel, concrete, diamond plate steel, fiberglass, FRP, galvanized steel, glass, hot rolled steel, LVL, Masonite, stainless steel, any wood species including exotic species, and many more.

Our most common specialty includes the cold pressing of solid wood stave to our patented and patent pending core material, resulting in natural wood doors that can be guaranteed to remain warp-free for 50 years. Unheard of in the wood working industries. We also supply high end millworks with hot-press-ready warp-free substrates to apply their skins to.

Light Openings

Available in any size and any shape, based on your drawing(s).

STC-rated Sound Doors

We assist in the creation of sound reducing or sound proof doors which can be STC-rated at our local world-renowned pro sound testing lab. Some typical composite configurations include combinations of steel, sheetrock, MDF, and other materials to achieve the sound proof results to meet your specifications.

Fire Proof Doors

We build fire proof doors to your specs and can have them rated at the fire-rating facilities selected by our fire proof door clients.
