Breaking News: Thin Doors Need Strength Too!
Sing Core has always been on the leading edge of the reinforced structural panel industry.
Our panels are among the lightest, strongest, and overall best on the market.
This panel is super thin for its overall span. Overall thickness is only 1 3/4″. Our patented torsion box honeycomb allows us to create lightweight high strength panels that can be any size without any warping. Solid wood would be very heavy and can potentially warp shortly after being produced. This panel is a whopping 65 1/2″ x 120″ and only weighs 139.6 lbs.!
| As you can see, the skin is birch plywood that is less than 1/8″ thick. Combined with our torsion box honeycomb design, this panel will be stable and remain rigid for many years. Due to this panel being truly flat, it can stand alone on edge. If there was any deflection, the panel would be unable to balance.  |

| A door with these dimensions is greatly feared by many door manufacturers. A door like this is nearly impossible to build without having issues. Common issues with doors so large and so thin include warping, delamination, prevalent weak points, and many others. If this were produced with solid wood, the door would be unable to stand alone due to not being true flat. Sing Core’s true flat doors and panels comply with AWI standards and can stand alone. |  |

Sing Core’s patented lightweight and high strength torsion box honeycomb core design makes building oversized doors easy and provides lasting strength and durability. We know our doors and panels are among the lightest and strongest on the market, so we guarantee every door and panel for 50 years! |
We never do veneering in house. We only trust local professionals for veneering services. Sing Core only provides substrate to be veneered. We highly recommend using your local veneering professionals. Veneering requires highly trained professionals to ensure a quality finished product.
Our substrate with MDF is very good for hot pressing as well as preventing telegraphing in the outer skin. This is the best option for ensuring a quality veneered door panel. With Sing Core substrate and 1/8″ MDF, no cross-banding is required. MDF is a very stable substrate to use.
For other applications, plywood is very strong and provides the best dimensional stability. This is the best option for applying overlays, such as wood staves, drywall, concrete board, etc… We offer many different plywood options, see our skin type page for more information.
