Make the Best Butcher Block

Make the best butcher block and much more, Sing Sandwich is much lighter in weight than solid wood but creates high strength Eco-friendly products such as floor, wall, roof, table top, furniture trade show display, etc… with all the beauty of wood but without the warp, twist, cup or other problems associated with solid wood and can be used just like you would any lightweight plywood.

Some of the best high-end furniture features butcher block, which is an elegant display of the natural beauty of wood grains. You see butcher block featured in everything from doors and countertops to furniture, like cutting boards, kitchen islands, tables, workbenches and large conference tables. The problem is, that butcher block tends to bend and twist thus compromizing the structural integrity of the project.

That’s where Sing Sandwich comes in to rescue the day. For years, using Sing Sandwich as substrate has been the high end millowork’s secret weapon for making non-warping butcherblock surfaces that stand the test of time.

A 4 ft x 8 ft x 1.5 inch Sing Sandwich panel with plywood skin weighs approximately 55 lbs. 55 pounds is a fraction of the weight of the equivalent piece of plywood… and heavy plywood can be dangerous to maneuver and/or requires extra equipment to accommodate. Even so, plywood could not be true flat or super strong like the equivalent Sing Sandwich panel.

That is why the Sing Sandwich panel is perfect for:

  • Shelf
    • Cut to any width for lightweight strong shelf, long span capacity.
  • Substrate
    • Insulated, true flat, lightweight, super strong for door core, table core.
    • Slice to any thickness.
  • Furniture components
    • lightweight , strong and long lasting non warp high quality  furniture.
  • Tiny house
    • For wall structure, floor substrate, room loft floor.
    • You may use one inch thick plywood to build your tiny house but it will not as straight as Sing core, it will be more than double the weight of Sing Sandwich panel
    • One inch thick plywood will have only about half of the strenght of sing sandwich
    • It cost more to ship heavy plywood and cost more than Sing Sandwich panel with same grade of quality.
  • Countertop
    • substrate could be finished in any exterior material
  • Ceiling
    • Lightweight ceiling.
  • Hurricane
    • window and door protection cover.
  • Use Sing Sandwich

Insulation: Sing Core has built-in insulation value with an R3 to R6.5 rating per inch, depending on client’s needs/specifications.

Sound deadening: Sing Core’s filler material has natural sound-deadening properties. Other sound-deadening options are available at customer request.

Light weight: When compared to other materials Sing Core weighs much less, as much as 50% less, or more, as little as 4 lbs. per sq. ft. yet eco-friendly. This advanced technology used in the aviation industry is now available for use in your home.

Strength: Sing Core based on 2″ x 2″ grids and 3/4″ thick = 660 PSI. For instance, aluminum 3/8″ grids = 30+ PSI (smaller grids should be more strength). Sing Core’s superior strength comes from its advanced torsion box design.

Solid: Sing Core is solid like a rock. While the vertical wood grain torsion box core may be compared to other hollow honeycomb cores, the Sing Core voids are not hollow as they are bonded wall-to-wall and filled with recycled foam for a strong, solid substrate.

Eco-friendly: Sing Core is manufactured using natural wood fibers, no formaldehyde, or toxic chemicals, is created using less energy than any other core material with little or no waste.

Renewable: The structure of Sing Core is 100% renewable (nature-grown) clean fiber and/or recycled material.

Oversize: Sing Core excels in area of large oversize products due to its unique properties and can be up to 50 foot length.

Dimensionally stable: Sing Core is the most dimensionally stable building material allowing us to create large, oversize products (i.e., doors, up to 50 ft.) that are true flat exceeding AWI standards and can be guaranteed to be true flat. Large oversize panels can be truly dimensionally stable without any movement due to temperature and moisture change.

Affordable: Even though Sing Core technology is used in high-end applications, we make it affordable for broad use in a large number of applications. Sing Core performance is comparable to any high-end core but could be as little cost as low-end wood product core.

Waterproof upgrade: Sing Core is available in waterproof upgrade, to accommodate your specific water resistant requirements.

Fire retardant upgrade: When used in fire retardant applications, the Sing Core fire retardant door is the lightweight, super-strong, eco-friendly alternative.

Bullet-proof upgrade: In high-security end products, most cores used in bullet-proof applications are heavy in weight, causing strain on the infrastructure, unlike Sing Core.

Thickness available: Sing Core is readily available in many thicknesses, up to 6 inches in standard thickness, with custom thicknesses available.

Skin options: For many different exteriors including (but not limited to) aluminum, cement board, cold roll steel, concrete, ceramic tile, fiber glass, galvanize metal, glass, MDF, metal, plastic, plywood, solid wood, stainless steel, etc… see Sing Panel

Easy to machine: Sing Core is easy to work with in the shop or on-site for sawing, sanding, adding solid wood implants, gluing, cutting and fastening.

Fast turnaround: In you’re in a rush, only Sing Core can be custom made within 24 hours and is proudly manufactured for you in the USA.
