SingCore Fiberglass FRP Extreme Weather Doors

The doors to your home are usually the weaker points in a structure’s integrity. SingCore FRP weather resistant and extreme weather doors are a sure way to protect your home or business. When you have SingCore FRP extreme weather doors installed, you can be confident your FRP doors will not fail during extreme weather, tropical storms, or hurricane like conditions. The for When wind forces hit a building, all loads are transferred to the door guides and wall angle. There are two load forces exerting on the hurricane proof doors. Dead load represents the total door hang weight while the wind pressure forces are live load. The critical wall fasteners within the opening height handle transferring the live load. Though not constant, live load forces can greatly exceed the dead load force. Having a solid, full height door mounting surface at the door jamb is critical. Our Fiberglass FRP Doors are not only extremely lightweight, but stronger than steel pound for pound and can be guaranteed to be truly flat.

Protect your home and family by installing SingCore FRP extreme weather doors. With SingCore extreme weather doors you are safe from door failures. High winds from hurricanes or tropical storms cause impacts from debris that lead to property damage or people injured or killed. Do not get left stranded without a door and have a wide opening on your home during extreme weather conditions because not only will you not want to make repairs to your home during a storm or hurricane, you will unlikely find any stores open and driving conditions will be dangerous. Not to mention, without doors, you, your family, and your property are no longer secure inside your home without a door to shut and lock. High winds and hurricanes will seriously affect your doors. If your doors fail, they will create openings into your home. Those new openings will allow air to forcefully flow into your home. The force from those high winds caused by extreme weather, tropical storms, or hurricanes can fill your house so fast with outside air that the roof of your home will blow right off!

If you live in an area where hurricanes are a common natural disaster, it’s important that you take precautions to prepare and protect your home from damaging winds and flying debris.

Honeycomb Panels

Welcome to Honeycomb Panels USA, the only Eco-friendly manufacturer of the most lightweight high-strength honeycomb panels in the United States.

Honeycomb Panels USA manufactures a patented new generation of honeycomb panel that outperforms all other honeycomb panels anywhere.

How to make the best honeycomb panels in the world

The secret behind making the best honeycomb panels in the world, begins with the internal structure of the honeycomb panels themselves. Our honeycomb structure is made of natural vertical wood grain fiber in a torsion box configuration. This creates an enormously high strength torsion box honeycomb panel… but Honeycomb Panels USA does not stop there…

Patented torsion box honeycomb panels go even further by filling the empty spaces of the torsion box honeycomb structure wall to wall with rigid recycled foam. Sandwiched between two stress skins using waterproof formaldehyde-free adhesive creates the most lightweight, high strength solid composite core honeycomb panels ever invented.

Honeycomb Panels USA wood torsion box honeycomb core structure foam composite honeycomb panel

How strong are Honeycomb Panels USA panels?

Honeycomb Panels USA panels have been independently tested at Washington State University at 660 PSI (stronger than steel pound for pound); compare that to other honeycomb panels commonly used in the aerospace industry that test at only 10 to 100 PSI with very little shear strength.

They are so strong, in fact, that you can traverse long spans without much support, which is why the United States Military, NASA, marine and aerospace manufacturers rely on Honeycomb Panels USA for the strongest most lightweight panels.

Insulated Honeycomb Panels

Honeycomb Panels USA panels have a natural insulation quality built in to the structure itself that imbues each honeycomb panel with insulation from heat, cold and barometric environments with a rating of R-3.5 or R-6.5 per square inch of honeycomb panel thickness.

This insulation also creates a sound barrier with its sound deadening qualities for increased privacy and noise control in industrial applications.

Large and Oversized Honeycomb Panel Projects

One of the unique uses of Honeycomb Panels USA’s torsion box honeycomb panels is in the large/oversize division of projects around the world.

Weighing in at a fraction of other building materials, our honeycomb panels can be created in sizes up to 40 ft. and up. While size and weight are considerations for shipping abilities (the United States Military has ways to overcome super large panel shipments that may not be available to the average commercial contractor, distributor or supplier). Honeycomb Panels USA has devised a system for creating modular honeycomb panels that can be shipped as multiple components and assembled on site while retaining complete structural integrity and can be guaranteed to be completely flat following assembly and for a minimum of 50 years without fail.

50 Year Honeycomb Panels USA Guarantee

That’s right. Only Honeycomb Panels USA can offer a true flat guarantee that states that your premium honeycomb panels will be true flat and will stay flat, will not warp, bend, twist, cup or otherwise fail for 50 years, backed in writing.

How Honeycomb Panels Are Made in the USA

patented honeycomb plywood lightweight high strength wood torsion box exposed viewHoneycomb panels by Honeycomb Panels USA use a patented technology that is the perfect combinations of old school artisan craftsmanship and high tech lightweight technology resulting in a composite engineered plywood product that affordably out performs any other honeycomb panel.

Most other traditional honeycomb panels to may achieve the goal of being lighter in weight that other building material – and this has truly been a breakthrough in the last 50 years helping to bolster aerospace technology and other design complications that may have hindered aggressive progress.

stack of marine grade honeycomb plywood lightweight high strengthWhile hugely valuable, traditional honeycomb panels regularly fail strength tests as most have very low PSI strength (i.e., 10 to 100 PSI). It was this deficiency that led inventor Peter Sing on his life long journey to find a structural answer to the issue of lightweight and strength.

The patented process that he discovered required a melding of old and new technologies to develop reinforced structural insulated panels that can achieve 660 PSI (or much higher depending on your required specifications). These resulting panels challenge the laws of physics as we know them.

Also, Sing’s revolutionary honeycomb panels are not only lightweight and high strength, but they are an ecologically friendly and sustainable product made right here in the USA and can be guaranteed for 50 years.

How Honeycomb Panels are Made in the USA

Honeycomb-Panels-Patented-Wood-Torsion-Box-Structure-Made-in-USAUnlike other honeycomb panels that feature non-earth-friendly honeycomb structures that are relatively weak but lightweight, Honeycomb Panels USA honeycomb panels start with a vertical grain natural wood torsion box structure.

This high end lightweight high strength solution has been used by wood craftsmen for thousands of years to develop lightweight, large flat structurally sound panels with the strength to cover long spans with much less risk of failing. The downside of this was that it could not achieve flatness over time due to the nature of the wood that tends to bend, warp and twist due to change in moisture.

see-inside-honeycomb-core-wood-torsion-box-filled-with-foamTo combat these limitations, inventor Sing made two significant modifications to the oridinal torsion box design.

The first was to change the orientation of the wood grain. Traditionally, craftsmen built the torsion box substructure with horizontal wood grain. By flipping and cross cutting the box walls so that their grain was oriented vertically, Sing was able to increase the strength of the torsion box structure many time. But he didn’t stop there.

The second major improvement was to fill the empty spaces within the torsion box structure with rigid foam (which is 90% air) wall to wall, creating a solid, lightweight structural base material that when sandwiched between two stress skins is stronger than steel pound for pound.

honeycomb-panels-usa-green-eco-friendlyEco-Friendly Manufacturing in the USA

The manufacturing of Honeycomb Panels USA uses less energy and manpower, creates very little waste, using the best of natural and recycled materials resulting in an evergreen structural building material made in the USA that will last for centuries without fail.

Honeycomb Plywood

patented honeycomb plywood lightweight high strength wood torsion box exposed viewHoneycomb Plywood by Honeycomb Panels could be the best sustainable ecologically responsible building material to surface within the last century that is lightweight, high strength and fully insulated.

Honeycomb Panels’ honeycomb plywood marine ply is so easy to use; any standard wood worker, millwork or wood shop can use our patented honeycomb plywood without any additional skills or equipment, just as though you were using plywood.

Don’t be fooled by its appearance or ease of use. Even though our honeycomb plywood marine ply looks like regular plywood, there is nothing normal about this newest generation of composite materials to hit the woodworking industry.

The boating industry and the U.S. Navy are embracing the attributes of our patented honeycomb plywood to replace marine plywood. Marine plywood is heavy and cannot maintain a high level of flatness or precision, like honeycomb plywood by Honeycomb Panels.

Unlike traditional marine plywood this honeycomb plywood has amazing characteristics that cannot be found elsewhere in any affordable flat building material.

stack of marine grade honeycomb plywood lightweight high strengthFor instance, our patented honeycomb plywood is:

  • Eco-friendly
  • Lightweight
  • High strength
  • Insulated
  • True flat
  • Stay flat
  • Can be waterproof plywood
  • Requires no special handling
  • Eco-friendly

Honeycomb Panels makes our honeycomb plywood right here at our factory in McCleary, Washington in the USA. Our honeycomb plywood may be the only structural building material made in the USA and exported throughout the world.

patented marine grade structural honeycomb plywood for boat builders


At one-third the weight (or less depending on the thickness) this revolutionary new building material helps to reduce energy costs significantly; less expensive to ship across the USA or the world, using less fuel and natural resources with less carbon footprint. At the construction end; less equipment, energy and fuel consumed on-site while saving labor costs and fewer injuries.

High strength

Our honeycomb plywood is stronger than steel pound for pound, testing out at 660 PSI (while other honeycombs are between 10 and 100 PSI) and can be easily increased to over 1400 PSI or more (if necessary to meet your specifications).


Honeycomb Panels’ honeycomb plywood is based on their insulated panels’ design that is packed full of solid insulation wall-to-wall between the internal structure grids. The insulation panels can be used as any exterior grade plywood.

True flat

No other high strength affordable insulated building material can be as high precision for true flat surface (with 1000ths of an inch) with little or no variance depending on the desire surface material.

Stay flat

Unlike other flat building materials that may be flat when manufactured or installed, honeycomb plywood by Honeycomb Panels is designed to stay flat for 100 years and guaranteed not to warp, bend or twist for 50 years.

Can be waterproof

Regardless of your intended use, you can use our waterproof plywood honeycomb panels to handle any extreme weather, underwater or water storage applications.

Requires no special handling

This new revolution in building material is completely simple and easy to use just like ordinary plywood. No special saw blades, tools or specialized skills are necessary to bring your designs to life in the most sustainable Eco-friendly way.
