How Does the Sing OEM Process Work?

Establishing the Need of Sing Core

There are many reasons that door manufacturers seek out patented Sing Core as their OEM door substrate; some of the most popular ones are:

Sing doorway to a better door 50 year non warp guaranteeCreating a Superior Door Line

Some door manufacturers are looking for ways to distinguish themselves from other door manufacturers. They seek out an OEM relationship with Sing Core to design and build an ultra premium line of doors that have unique characteristics that cannot be found by using any other door substrate material.

BIG Door

Many door manufacturers have problems with large doors (especially over 7 ft. tall) in that while they look magnificent upon installation, dealing with door warp on a regular basis is a constant maintenance cost associated with big doors.

Oversized large paint grade Sing pivot door panelThis is where Sing Core door substrates shine because the substructure of the core itself is a combination of wood torsion box (using vertical grain matrix framing) filled with recycled rigid foam creates a lightweight, high strength solid substrate that will retain its original shape and structural integrity over time; higher precision and lasts longer than any other known door building material.

That’s why more and more, you are finding Sing Core™ inside some of the biggest aircraft hangar doors, large sliding barn doors, factory doors, large commercial doors, warehouse doors and large garage doors.

Non-warp Door

Sing Core™ is the only door core material that enables our door manufacturers to deliver doors that do not warp regardless of size or external materials in either interior and/or exterior doors, if they are designed by our Non-warp True Flat Specialists. Sing Non-warping door blanks are available in any type, style, shape, exterior skin and/or composite configuration.

Insulated Door

Rumney Guggenheim Gallery Williamsburgh Savings BankInsulated doors offer enhanced separation between two areas separated by an opening, doorway or egress point. Sing Core insulation starts at R3.5 per inch and goes up from there, based on architectural specifications. Insulated door are of primary interest to architects, designers and engineers seeking soundproof door, hurricane doors or other weatherproof door where an insulated door is specified.

Security Doors

Sing Core is of primary importance in security doors of substantial size. Large security doors are difficult to manage normally due to weight; this problem can be solved with the Sing solution. A security door can be used in a variety of circumstances and applications including impact doors, and bulletproof doors.

Television-studio-moveable-sound-walls-sound-proofUsing Sing Core™ inside, impact resistant doors don’t have to be heavy weight, which causes unnecessary stress and strain on both the hardware and structure, while delivering all the security desired including increased privacy due to innate door insulation.

Specialty Doors

Sometimes a custom door manufacturer, millwork or door manufacturer faces a job that requires doors with unique attributes to accommodate a particular usage following installation.

Specialty doors may need particular characteristics to meet the requirements of the end user. Architects, designers and engineers can use Eco-friendly Sing Core™ inside to have greater control over:

Sound deadening
Impact resistance
Any size
Any style
Any performance
Any exterior surface
