About the Inventor

SingCore is the strongest lightweight, earth friendly, low cost material with endless applications. With SingCore honeycomb panels you can build strong, lightweight, environmentally friendly products. Potential applications include furniture, concrete tables, truck bodies, boats, and airplanes. The possibilities are endless. It is even possible to build an entire home from floor to roof. A Sing home is the strongest, lightest weight, most energy efficient home in the world.

When Peter Sing was a teenager, he learned about the properties of the honeycomb structure from the aluminum honeycomb used in aircraft. It was very lightweight and high strength material but was expensive to produce because of the energy consumed in the manufacturing process. Peter worked to invent a honeycomb material that used renewable resources and a low-energy process to produce a low-cost, high-strength honeycomb building material. This is how a life time of invention started – and now, after 30+ US patents, SingCore Honeycomb Products have become the best combination of natural materials and human ingenuity you will find on the market today.

Wood is next to earthen material as the most commonly used building material on our planet. Grown naturally for millions of years, humans started to use wood in the construction of their shelters after they moved out of caves. For thousands of years our ancestors cut natural wood to build furniture and construct shelters. Later, engineered wood products started to replace solid wood: laminated wood, plywood, chipboard, OSB (oriented strand board), and the list goes on.

The invention of the Sing Honeycomb process is based on very simple idea: it takes less wood fiber to provide the same strength as solid wood, and with a better insulation value. Imagine taking 100% of the wood fiber out of the solid wood and reintegrating 10% of that wood fiber into vertically structured foam arranged in geometric shapes. The honeycomb core material is made of thin wood veneer, which is the main component of plywood, surrounding an insulated and sound-deadening foam base material. The implanted vertical grain veneer is composed of high strength wood fiber . It is the strongest, lightest weight, low-cost material ever created with natural materials.

Environment & Energy Friendly


How is Sing Honeycomb “Green”

1   Sing Core - the most earth-friendly way to use natural renewable materials
Sing Honeycomb core structure is made of 100% natural vertical grain wood veneer. This is what sets us apart from our counterparts who use honeycomb core materials such as paper, particle board, aluminum, and plastic. Here at Sing Honeycomb, environmentally friendly construction is our mission.

2   LCA (Life Cycle Assessment)
Sing Honeycomb strives for a "cradle to grave" measurement of a product's environmental impact from raw material extraction and manufacturing through distribution, use, maintenance and disposal.  An obvious example is a coffee cup made of styrofoam compared to a coffee cup made of the same material but enclosed in a solid container. Solo cups are only used once and then disposed of, filling our landfills unnecessarily. But imagine that the same Solo cup material is put made into a permanent coffee cup that could last ten years without being replaced.  Sing Honeycomb protects the foam by sandwiching it inside a durable wood framework.   LCA studies show that using wood is less harmful to the environment than steel or concrete in terms of embodied energy, global warming potential, air emissions, water emissions, and solid waste production. 

3 Long Lasting
Sing torsion-box sandwich panels are warranted for ten years*, but may last much longer.  This means Sing products will not need replacement or disposal for many years, cutting down on the resources used to manufacture panels. The foam used in Sing Honeycomb Core Panels comes with a 20-year thermal performance warranty, dimensional stability, compressive strength, and water resistant properties. See instructions for repair and recycling.

4   Energy Friendly
Energy Saving in general: Our Sing Honeycomb Core starts from raw material, production process, shipping and product lifespan, and the recycle/reuse are the major energy savings characteristics.  Sing products has set a new bench-mark for energy savings and is less harmful to the environment than other honeycomb products.  Sing core is the most energy friendly, covers more broad-range products in modern time today, all guaranteed by the inventor and founder of Sing Core.
Energy Saving as insulation
Insulated, draft-free sandwich panels save your heating costs Sing has a long term stable R-Value. Sing Sandwich panels assemble and install quickly, saving you man power and time.

5  Leading edge of composite technology
Composite material is a feature of energy solutions to solve our structure needs.  Patented Sing Core is the leader of composite material products.  Sing Core takes less energy to produce the strongest, lightweight material. Whether the product is called a torsion box in the wood-working industry, a honeycomb panels in the aviation industry or a sandwich panel in the building industry, it’s all the same thing and they all function in the same way – it’s a composite material sandwiched with a lightweight core.  There are many different core materials such as paper, aluminum even plastic honeycomb, but our Sing Honeycomb is a torsion box or sandwich core structured with a vertical grain core that takes less energy to produce from renewable resource to our finished honeycomb core that we’re proud to say is strongest, lightest weight core that is the most environmentally friendly composite product ever invented.

6   Recycled
Our foam core has a recycled content of 20% and is 100% recyclable.

Honeycomb Highlights

  • High Strength - Sing Honeycomb Sandwich Panels have a compression strength of up to 660psi, and can be crafted to support over a thousand pounds.

  • Flat and Straight - Sing Panels, products and beams are manufactured to be the most flat and straight.

  • Lightweight - Sing Honeycomb Panels and Beams weigh less than a third as much as solid wood.

  • Rot Resistant - Sing Panels and Beams are rot resistant, even with continuous ground contact. They can withstand extreme moisture, humidity and extreme heat.

  • Sound Deadening Properties - Sing insulated wood panels offer unsurpassed sound deadening properties, this ensuring that you can enjoy the quiet solitude of your home or cabin.

  • Long Lasting- Furniture (and other products) made of our Honeycomb can last 10 times longer than furniture made of paper honeycomb and particleboard; that is why we back all of our products with a 10 year structural replacement/repair warranty under normal use.



  • Buildings can be constructed with thinner walls, while roofs require shorter fasteners; thus, less material is needed and wasted!

Our goal is to protect the environment by cutting down on energy and material consumption.
The environmental benefits of rigid polyurethane foam used in almost all honeycomb products include increased energy efficiency and reductions in energy-efficient construction costs, reduced project weight and savings of all the construction components that the material replaces.

  • Given the widespread adoption of rigid polyurethane foam in today’s construction, these savings are multiplying at an increasing rate around the world.

Better insulation typically results in lower energy use. In some cases, mechanical heating and cooling equipment can be downsized, further increasing space utilization.
Less complicated and lighter-weight products use less energy to create and ship.

Strong Honeycomb Panels

Thermal/Mechanical Performance

Polyurethane and polyiso foams function in temperature extremes, do not deform or distort, and are not subject to damage by the moisture that may result from condensation.
The mechanical strength of these foams is remarkable. High compressive and sheer strengths allow low-density insulating cores to be faced with relatively thin steel or aluminum, yet span long distances unsupported. For example, the foam can hold together many of the components in a refrigerator or hot-water heater while it continues to perform as thermal insulation.

For applications that already use EPS foam such as coolers, truck doors, walk in freezers, it is a no brainer to use Sing Core. Sing Core provides a longerslasting, more affordable alternative to conventional foam products. With our grids your product will be 10 times stronger than without them.

Energy Efficiency
Polyurethane and polyiso foams have one of the highest insulating R-values per inch of all commercially available products today. Typical values range from R 5.6 to R 8 per sq. in., saving you hundreds (possibly thousands) of dollars a year on heating and cooling your home.
Polyurethane foam sealants, applied on-site, expand to fill energy-wasting, air-infiltrating gaps around window frames, plumbing pipes, and electrical outlets.
“Reflective” plastic coverings over polyurethane foam-insulated roofs bounce sunlight and radiant heat away from a building, helping the structure stay cool and reducing energy use.
Entry doors with a rigid polyurethane foam core help inhibit sound and add insulation value that further reduces heating and cooling energy needs.
