Simply Make the World A Better Place

Sing Core has introduced leading edge technology that is truly a revolution in building materials. Providing this material to the world is in-line with Sing Core’s mission to make the world a better place for the earth and all creatures.

Patented Sing Core is the only Eco-friendly lightweight, high-strength building material that will bridge long spans without complex/heavy framing with minimal deflection under load and will not warp, bend or twist over time. This revolutionary composite comes in your choice of panels or posts and beams and is the only structural material that can be made to be true flat and guaranteed to stay flat for 50 years.

Sing Panels possess super-strength the secret of which relies in its simplicity and our commitment to not overcomplicate its simplicity in any details of this concept. How do we keep it so simple?

Simple Design

The structure of patented Sing Panels is simply a fusion of old-world technology and space-age technology and consists of four components, that when combined in the patented Sing process, result in the only affordable Eco-friendly lightweight high-strength building material in the world.

1 – Wood Torsion Box Structure

Wood torsion box structure has been used by high-end woodworking craftsmen for thousands of years as the labor intensive solution for building lightweight tabletops, countertops, desks, etc… Due to the painstaking torsion box process, these products could only be afforded by the extreme elite.

Sing Core utilizes a torsion box core with an important improvement: by flipping the grain to run vertically, instead of horizontally, Mr. Sing’s process picks up a 400% PSI strength increase over standard torsion box structure… but there’s more…

2 – Recycled Foam

While wood torsion box is an excellent lightweight substrate with superior PSI strength, the nature of the torsion box design itself does not have the shear strength performance that is so illusive in high-end applications that require lightweight, high-strength and unparalleled shear strength.

Sing Core’s solution is to pack the torsion box voids wall-to-wall with recycled foam that creates a solid flat substrate surface to build upon. The weight is comparable to hollow core, paper core or foam core, because it is still only 8% natural wood fiber, packed with recycled foam which is 80% air.

The foam packing not only makes the surface solid and perfectly flat for outstanding shear strength but also imbues the structure with insulation and sound deadening qualities.

3 – Formaldehyde-free Adhesive

The Sing Core process includes using a high-end adhesive to bond all the material composites together. Though expensive, this formaldehyde-free glue perfectly fuses all the components into a solid piece that is waterproof and will not delaminate over time.

This special adhesive is used in an effort to support Mr. Sing’s commitment to build long-lasting products that will last for centuries (not filling landfills, like less expensive disposable items that we’ve become so accustom to these days).

4 – Stress Skin

To complete the process, Mr. Sing adheres a lightweight plywood exterior surface material to seal the open ends of the torsion box resulting in a solid super-strong product (starting at 660 PSI as tested at Washington State University) that looks like a standard piece of plywood or post and beam (depending on the dimensions) and can be treated, sawed, cut or ripped just like any other lumber product without any additional tools or skills.

Solid edges and implants can be included or window/glass opening can be pre-cut based on your needs and/or requirements.

To make things even better, the exterior material (bonded stress skin) can be any flat building material – or combination of building material – to meet the demands of the architect or designer offering the ability to replace any heavy non-eco-friendly solid building material.

Simple Order Process

In keeping with Mr. Sing’s commitment to keep it simple, he has initiated a simple ordering process whereby anyone can obtain a price simply and easily using his free online price quote.

It’s as easy as 1, 2, 3

1 – The length

How long does your table, window, door, post or beam need to be? Mr. Sing’s factory is tooled-up to manufacture panels, posts and beam in up to fifty-foot lengths.

2 – Width

Again, the Sing process can accommodate nearly any width (which on occasion does cause challenges for shipping particularly large components, but since this is what we specialize in, we can figure out the best way to deliver the end product to you).

3 – Thickness

Of all the possible variances, the thickness of Sing Core is suggested not to be less than one-half (and three-quarters is even better) of an inch to see the structural benefits vs. the cost. Standard thicknesses accommodate up to 8 inches, but could exceed that to meet your specifications.

Options in the ordering process may include alternate skin combinations/variations to achieve the performance results that you require for your challenging project.

Simple Web Site

Sing Core may be one of the largest building material web sites in the world due to the wide range of applications of this revolutionary new building material. The mere size of its contents could be overwhelming to the average user if not for the simple method of organizing all that information in a way so as to be available to the average user in a logical format.

Starting with a hierarchy that is similar to an aerospace parts catalogue, one can navigate the natural structure of the website via an organized Table of Contents.

The top Navigation Bar provides quick and easy access to the main parts of the site with simple single-clicks from any web page, including one-click access for Online Pricing.

A Site Search function is also provided for those used to searching for what you want and perusing the search results.

Simple Process

Sing Core has made the process simple enough to get this material into the hands of the people who would like to enjoy long-lasting maintenance-free enjoyment of their projects or products while making the world a better place by using his Eco-friendly lightweight high-strength building material.

Sing Core is the manufacturer of our patented invention and as such we are not qualified to deal with or train end users on the uses for – or handling of – the building material itself.

If you want to use patented Sing products in your upcoming project, there are ways you can make that happen.

1 – If you are a manufacturer, millwork, high-end woodcraftsman and you already have a commercial account with us, then you have access to our materials – including the rare, high-end one-off custom projects that we help to solve every day. If you are a high-end retail establishment, you may be eligible for a commercial account. Please contact us and find out, today.

2 – Lumber retailers and sheet product distributors are invited to carry regularly stocked Sing Core products that retail well to local builders, contractors, woodworkers and DIY homeowners.

3 – DIY creative artists are supported by Sing Core indirectly. Though we do not have support available for the end-user, we do provide all the necessary information for your due diligence as you research the integration of Sing Core products into your project.

Homeowners or project creators ask, How Do I Get Sing Core?

If you possess adequate woodworking and building skills, you may be able to educate yourself enough to begin your do-it-yourself Sing project. For projects like these, please contact your local lumber supply or home building center. We’ve made it easy for them to set up with us and we will ship the items that you want directly to that supplier. You can easily pick it up at their location or have it delivered to your location (if they offer that service).

Simple Way to Tell the World

Much of what we do to promote Eco-friendly Sing Core is done by word of mouth based on over-delivering affordable options in the areas of affordable lightweight and high-strength.

You can join the Sing Team by singing our song. We invite you to help us spread the word about Sing Core by joining our Referral Program and we will pay you 20% of every sale that is made through your referral link.

It’s free and a great way to help us make the world a better place together.

Storm Doors

Applications -> Building Components -> Doors -> Storm Doors

Sing Storm Doors are severe weatherproof flush doors or French doors that can feature any size or shape of lite opening/window cut-outs that will accommodate impact rated glass.

When discriminating architects, homeowners, designers and the most high-end millworks are seeking to find storm proof front doors or tropical storm patio doors, they have come to trust the unique high performance of Sing Storm Doors as their long-term solution for exterior doors that are 100% extremely exposed to unbridled elements.

Sing Storm Doors are superior functioning high security storm doors that are featured in many a hurricane-proof house, while maintaining the elegance and beauty of the natural appearance of wooden storm doors.

Wood Storm Doors

Sing Core has the ability to provide extreme weather resistance in wooden storm doors by starting with the patented material invented by Peter Sing. Everyone knows that it is impossible to use a solid wood door as a storm door because wood (due to its innate natural qualities) will bend, warp and twist. This movement will cause the door to fail, either in the seal between the door and the frame or by compromise the protective coating of the beautiful wood storm door.

One small crack in either the surface or the seal could cause the loss of your home. That’s why upscale hurricane-proof homes can feature Sing double storm doors or custom storm doors with the highest confidence that your investment is protected, leaving you safe and secure when storms start brewing, which also puts less pressure on federal emergency management.

Hurricane Doors*

Introduction of the Sing Hurricane Door* was an instant success, with its fiberglass exterior surface on the one side and beautiful wood (or any other flat building material) interior surface for unparalleled hurricane protection*, high performance, beauty and elegance.

Even though Sing hurricane doors come standard as French storm doors in their appearance, Sing Core has the ability to alter the design to duplicate the look and feel of any other kind of door regardless of being a tornado safe storm door or not.

It is this ability for any Sing Storm Door to look like any door – all you have to do is provide us with a picture – and we can match the appearance of a pre-existing door if it is a replacement, or your dream decorative storm doors that have our fans depending on us to go the extra mile.

So, whether you’re looking for hurricane panels, hurricane doors or even hurricane garage doors Peter Sing’s hurricane impact doors* will leave you feeling safe and secure when you need assurance most.

Stainless Steel Storm Doors

Sing Core makes the most Eco-friendly lightweight, high strength, fully insulated metal storm doors in the industry, bar none. That’s why NASA, Boeing and the US Military branches trust us with their high performance metal impact entry doors.

Our metal doors for steel storm shelters or other applications are available in your choice of Sing Metals including aluminum, stainless steel, galvanized steel or any type of metal based on your specifications.

*Customer will need to perform lab tests to certify hurricane rating for local code compliance.

Aluminum Outdoor Storage Kits

Eco-friendly insulated aluminum Sing Panels are both lightweight and high-strength – more so than any other affordable building material in the world – are solving challenges facing architects, designers, contractors and industries, especially when facing issues with weight, strength load bearing capabilities or extreme weather protection.

Due to the unique properties of the Sing Aluminum Panel, we are being sought out as the most fast, cost effective way to erect aluminum outdoor storage sheds, garages, carports, metal buildings, mobile offices, even underground bunkers and fallout shelters.

Our popularity is vastly growing as engineers discover that complete portable storage units, temporary structures, metal buildings, office cubicles, temporary buildings and so much more.

Outdoor Storage

Sing aluminum panels are renowned for building structurally sound buildings in very little time with few man-hours and can b built by one person alone, or easily by two. Similar to our Tin House Kits, outdoor storage shed kits can provide you with all the aluminum panels that you need.

Why are Sing aluminum outdoor storage units so popular?

Because due to the internal insulation and torsion box/foam structure of Sing Core, each panel is a complete stand alone wall, floor, ceiling or roof.

Many outdoor Sing metal storage buildings can have a lot of functional applications including portable storage units, outbuildings, portable storage sheds, weather proof wood sheds or temporary storage buildings.

This is an excellent alternative to other portable buildings for sale, storage building kits, prefab sheds or other storage shed kits that are over-priced and take months to build.

If you’re contemplating your next portable storage building, you should be using Sing aluminum panels for your portable storage, wood storage sheds or portable shed.

Warehouse Office Structures

When you need to build an in-plant office, temporary cold storage, clean room, enclosure or partitions, Sing Aluminum Panels make this project quick, easy and painless. If solving your space and staging challenges is both important and rapid resolution would increase your bottom line, this is the answer.

Simply assemble the Sing Aluminum Panels in the configuration that would best suit your needs in the moment and you are ready to go with your temporary structure, mobile office or office cubicles. If you requirements change, or you develop a better way to reduce necessary floor space, reconfiguration is a snap.

Think of your Aluminum Sing Panels as modular walls for custom enclosures that can be reconfigured on-the-fly. Within hours your mobile offices can be converted to portable classrooms, industrial enclosures or used as a project enclosure box.

These interior aluminum enclosures can easily be assembled and left as permanent, or disassembled and reassembled as entirely new staging areas, partitions, room dividers, as a temporary office, portable rooms or instrument enclosures.

Commercial or Retail Metal Outbuildings

Sometimes in the real world of business you need outdoor temporary buildings to address a specific need that faces your organization. Sing aluminum metal building kits could provide you with the structure that you need in a short amount of time, and your solution can be realized with very little labor hours expended.

You could quickly assemble a mobile office, or have a stock of Sing Aluminum Panels on hand to erect modular buildings on-the-fly that provide safety and security for either inventory or staff.

It makes sense to have Sing Aluminum Panels on hand for your metal building needs that can be easily reconfigured to meet your needs at a fraction of the price of other metal buildings for sale.

In this day and age providing safe and secure environments for staff is or primary importance to reduce labor and industry costs.

A popular concern that patented Aluminum Sing Panels has been effective in addressing is that of tending to the needs of staff, visitors or clients who smoke. You can have an aluminum smoking room up and running within hours as your authorized smoking shelter that can be placed in a discrete location.

Other popular uses of insulated Sing aluminum small buildings as outdoor shelter include bus stop, parking kiosk, rain shelter, while providing a weatherproof enclosure.

Imagine having weatherproof enclosures that can be configured as an instant shelter that can provide you with temporary shelters, portable shelters or even a portable storage building so that you don’t have to rush out to find portable buildings for sale.

These instant aluminum waterproof enclosures can also be used as a temporary project enclosure box.

Auto & RV Metal Building Kits

Sing Aluminum Panels enable you to build a structure using our unique, “Don’t be framed,” technology. This means that you can build a metal garage without any framing because the structural framing is built in to each insulated Sing Panel, so all you have to do is to assemble the panels in the configuration that you desire. Entire structures can easily be built in a day with very little labor.

Whether you’re storing your classic car, recreational vehicle or boat, you can quickly and easily assemble one of our aluminum garage kits in a day with one or two people. You can do it yourself without highly skilled metal-working skills. No welding required as our Aluminum Sing Panels feature solid wood edges (or not) are as easy to work with as plywood. No special skills or equipment is necessary.

Whether you are looking at carport kits, metal garages or metal garages in general, Sing Core can supply you with the materials to do it right – better than any other prefab garage – for the best possible car shelter.

Imagine having a portable carport that you can assemble, disassemble and take it wherever you go. Of all the metal carport kits that are available, only Sing Core can provide you with an aluminum metal garage that is better than those other prefab garages.

Sing metal storage buildings are modular and can be flat-packed and stored when not in use, giving you the highest degree of flexibility in aluminum outbuildings or portable garages.

Sing aluminum portable carports can be used as a motorcycle shelter, RV carports, boat shelter or just about any other purpose that you could imagine for a metal carport kit.

Sing Aluminum Insulated Shed Kits

Insulated Sing aluminum sheds are lightweight and easy to build in a matter of hours but are extremely weatherproof and stronger than steel pound-for-pound. Using space-age technology, this revolutionary approach to building a nearly indestructible metal shed is unparalleled.

Aluminum Sing Core fabricated outdoor storage sheds can be portable storage units for outdoor storage and are widely used as wood sheds

Aluminum wood storage sheds are available as storage shed kits that include all the Aluminum Sing Panels that are necessary to build your insulated metal shed that can be built easily in a few hours without any framing, like other prefab sheds.

Your Sing portable shed can be an aluminum portable generator enclosure or portable shelter if need be. Sing aluminum storage shed kits have been used to build everything from portable storage sheds to industrial sheds, etc…

Survival Shelters

Gaining a wider audience in the survival community, Sing aluminum panels are the safest, easiest and quickest way to build underground bunkers or an instant fallout shelter.

Sing Core’s Smallest House in the World introduced the world to a safe, insulated, weatherproof small structure that could be built in five-and-a-half minutes that could be easily heated and used as emergency housing, temporary shelter, portable storage, garden shed, play house, etc…

This garnered the attention of survivalists, who started to use Sing aluminum panels to create catastrophe proof structures that could be built discretely and rapidly.

Projects resulted in many different function of the same basic shelter, including bomb shelter, emergency shelter, underground shelter or any number of other variations on this aluminum instant shelter idea.

If you’re thinking about building a survival shelter of your own in a day instead of months, you might consider using Sing aluminum panels to build your emergency shelters, underground shelters and/or bomb shelters.

No More Warped Door

50 Year True Flat Replacement Doors

Copper Door

Building the most stable door is our specialty. With our patented true flat technology, Sing Core provides clients with insulated Eco-friendly lightweight high-strength doors that prevent wood warping doors. Often we are sought out for replacement doors to solve the problem of doors that fail following installation. Doors – especially exterior, large or special purpose doors – are prone to warping, bending, twisting or cupping.

Why Do Doors Warp?

So many things can contribute the failure or the success of your large door’s performance.

Size: Length, width, thickness
Skin: Some materials are more prone to warp than others
Core: The core material will affect the door’s overall performance
Environment: Exterior facing direction, weather, exposure to moisture and/or other conditions.

FREE CONSULTATION for your next large door project. You tell our non-warp experts your door’s specifications and expectations and they can provide you with the only non-warp solution guaranteed for 50 years.

What if you started with a Sing door instead of using it as a door replacement?

Only true flat wood front doors by Sing Core can be guaranteed to be flat and stay flat and stay solid for 50 years. Most foam-filled doors might be straight but need patented Sing Core structural grids to keep it strong and tough to avoid failure following impact or due to exposure. Creating a warp-free large door is a challenge for all door manufacturers because it is almost impossible to make a large door that will be straight and stay straight over time. That is, of course, until the invention of Sing Core.

How can you make the most stable door that can be guaranteed true flat for 50 years?

Sing Core has developed true flat technology that consists of three phases.

#1: Sing Core

The first phase is to start with patented Sing Core as the basis of your true flat door. Sing Core is a composite honeycomb material consisting of natural vertical wood grain torsion box where the voids are filled wall-to-wall with solid recycled foam material that is 90% air. The natural wood torsion box inner frame yields only 8% of this natural resource in comparison to a solid wood door. This provides the strongest Eco-friendly, lightweight door core that will not warp, bend or twist.

#2: Skin Selection

The skin selection is matched to your desired appearance of the door. Do you desire a solid wood grain door? If so, what wood species? Besides wood, we can manufacture a Sing door to host any flat building material, including (but not limited to) aluminum, ceramic, concrete, glass, fiberglass (FRP), plastic, LVL, MDF, Mag-board, stainless steel, veneer, even more custom high-end surfaces like, Kevlar, etc…

#3: Performance Enhancement

Next, our true flat experts review the expected performance and usage of your door. Based on how you want your door to perform and under what conditions, our experts may incorporate additional stress skins to bond directly to the Sing Core base to match your desired outcome. How large are the dimensions of your door? Will your door be exposed to the elements? What extreme exposure, if any, will the door face? Will your door be used: Underwater, in temperature-controlled environments, as sound proofing, to prevent harm to persons or property, etc…?

Any Sing composite door can be guaranteed true flat for 50 years, while matching the appearance of:

Framed Stile and Rail Doors

Weatherproof Church Doors

Also called raised panel doors (when in reality it is not raised panel at all. The appearance of “raised panel” is obtained by graduated cutaways that compromises the integrity of the door). These doors are normally made of several different solid wood (or composite) pieces assembled by dowels or other connections.

True Raised Panel Doors

The individual components, connectors and adjoining seams tend to move due to moisture, temperature change or with heavy use or vibration over time.

By examining the red door (left) you would never know that this wood Sing door was not stile and rail yet will last for centuries without fail even though exposed to the weather 100%. The appearance of this door perfectly replicates the appearance of the stile and rail doors that were replaced.

Flush Doors and/or Solid Wood Doors

Solid wood doors are a romantic and nostalgic nod to days gone by, but solid wood is well known for bending, warping and twisting due to the natural grain of the wood itself.

LVL is a heavy solid core that is more consistent than solid wood in terms of warp, bend and twist when used in wood doors but will often fail (especially in doors over 10 ft. tall) and once it does begin to move, cannot be stopped or straightened as it has no memory.

Foam Core Doors

Foam core doors such as most FRP door, metal door, etc… are lightweight but have no strength or structural integrity.

Almost any impact will compromise the door causing the door to weaken and/or delaminate, unless it incorporates patented Sing Core structure grid technology.

Break a Leg

Only Sing doors can take the abuse without running the risk of breaking or delaminating.

If you kick a door, it is likely to break; kick a Sing door and you will break your leg.

The Sing Secret

The secret behind Sing Core’s success is not merely in the torsion box design (which has been used for hundreds of years) but in the orientation of the natural wood grain used to form the grids that are the basis of the internal structure for the patented non-warp base material enhanced by stiffening technology to counter-act potential warp.

In the past, torsion boxes were built with horizontal grain, that while running parallel will tend to fail by bending in harmony with the outer wood skin material. Sing Core flips this technology on its edge by contrasting the orientation of the wood grain to be perpendicular to the exterior wood grain resulting in many times the strength.

Previously solid Balsawood core has been used as door core with perpendicular oriented grain successfully but runs the risk of compromise or failure due to its natural characteristics that will also move due to moisture exposure, climate or temperature change. But it doesn’t stop there.

Next, inventor Peter Sing bonded recycled foam (which is a lightweight solid material consisting of mostly – 92% – air) wall-to-wall inside each void of the vertical grain torsion box grids for unsurpassed shear strength and solid core material throughout.

This is how patented Sing Core has accomplished nearly inconceivable strength in the lab (660 PSI, tested by University of Washington as stronger-than-steel pound-for-pound), yet still remaining lightweight.

All this combined with the Sing Composite Formula for specialized stress skin integration results in the only true flat doors that are built to last for centuries.
