Swing-out Carriage Doors

Are you in need of replacing those old carriage doors? Maybe you just want to spice up your home a little bit? Carriage doors are a great way to do this. They are very large, and yet so elegant. Carriage doors can replace your roll-up garage door. It will save you an immense amount of space! Carriage doors use a series of hinges instead of a track as the roll-up garage doors use. Using Sing Core makes your installation simpler, doors last much longer, and are significantly easier to handle. Easier handling means that your shipping cost will be even more favorable!

Hinged, swinging, swing-out, swingout, swing-in, swing, slide, or fold carriage doors for your carriage house garage can be found at Sing Core. The old-fashioned design, side-hinged garage doors swing open and closed from a hinged frame on either side of the opening. We create the most lightweight, strongest, and economically friendly doors. Traditional carriage doors are very heavy due to their size and structure, which causes them to need very heavy duty hardware to hang the door. The idea that carriage doors open on heavy duty hinges my not seem like a hindrance, but it raises the cost of hardware and make the door increasingly more difficult to install. So make it easier for yourself or your contractor to install your carriage doors by using Sing Core doors. Sing Core proudly makes any size (no matter how large) door tailored to your needs. Our doors weigh a third of a standard carriage door. Don’t think for a second that this weight difference alters the quality. Sing Core doors are the strongest doors on the market today. We believe so strongly in this that all of our doors are backed with a 50 year structural guarantee. No other door company can come even close to that!

Horizontal Wood Staves

Give your home the humbling, yet astonishing ambiance of the Kekkai, the Kyoto code, by using horizontal wood staves.

What is Kekkai?

The Japanese principles of Kekkai are very simple. A Kekkai is a boundary comprised of a simple, often vague, line or sign indicating a place of no entry. In Japan, Kekkai can be anything, but commonly used objects for creating this boundary can be a piece of bamboo, pile of salt, a rock, a gate, or even mountains are considered Kekkai. The vagueness gives everyone an opportunity to interpret the exact meaning behind a Kekkai. Usually it is a boundary, but it can also be used to show respect. The use of Kekkai in this way indicates your position and how others should behave in the given area. They are used to convey a symbol of respect between all things, living or not. Kekkai embodies the “spirit of consideration” for those who use them and those who are aware of them.

Ninety percent of our customers who choose to have a wood stave skin on their door/panel prefer the horizontal wood stave instead of the vertical wood stave. Wood staves are a beneficial choice when choosing a skin for a door/panel. What are wood staves?  A stave is a narrow length of wood, in our case usually 6 in., that runs the span of the piece. They are aligned on the edges to leave no gaps. A stave traditionally forms the sides of barrels and is now a great material to use for your next DIY project. Stave lumber cores are assembled using blocks or strips of wood that are from the same species. Wood staves usually have a thickness of 0.125 in. while veneer is only 0.020 in. thick. Wood staves are 16% thicker than a standard veneer skin. This may seem small and insignificant but it makes the door/panel much easier to repair. The engineered construction of our interior doors utilizes fused, solid wood pieces that are laminated to create a solid wood stave face. Wood staves can be used on any door; including but not limited to: pivot doors, sliding doors, even standard hinge doors. Wood staves are offered in a wide array of species of wood, including mahogany, which is a beautiful species for a door. There are too many types of wood to list, but if you can think of it, then we can do it!  Our selections includes domestic and foreign hard wood lumber and softwood lumber. Our wood stave selection cannot be matched! Solid wood doors tend to warp, which is why most doors should use Sing Core. Solid wood doors tend to warp, so choose Sing Core for your non-warping needs. Sing Core carefully engineers doors to withstand the test of time. We create the strongest, lightest, and most eco friendly doors for a fraction of the cost you’ll see anywhere else. Our doors all come with a 50 year guarantee that they will remain this way. Think of Sing Core the next time you need a core for your door. At Sing Core we use only the highest quality wood for any commercial or residential applications you need.

For those who did not know, you can wash facemasks for re-use. The process is simple and easy to do. We felt the need to make a video to show just how easy this can be. The daily use of facemasks creates a higher demand for them, which lowers supply amounts. This effect raises the price for facemasks significantly. We thought we would help by providing an alternative solution to save people money!

Here is where we will be posting all of the comments and critiques of the protective breathing apparatus. If you would like to add anything, please contact us at!

‘I think that we could simplify your design a little, to get the same “wash effect.”I am looking at rebreather designs, which use a sponge, brass wool, or similarly porous material that holds the liquids, and allows the air to pass through with lot’s of wetted surface area. Another variation are swamp coolers. This would eliminate the need for a rotating brush.A small pump to keep the surface wetted would be the only power draw.Here is a link to the concept: this concept could be scaled down to your filtration tube. Similar concept with a rebreather. The breathing air passes through a unit with a chemical solution in a porous material to keep it wetted and increase surface area:

Either way, a small fan to make up for the flow restriction, like that on a PAPR, would make breathing effortless.

I fully realize that valuable new ideas in the past have always been met with skeptics, and I don’t want to be dismissive when I may well be wrong.  But I have to say, I think you face a real uphill battle here for several reasons.
I did a little research on your competition, I see that 3M make a product, the Versaflo TR-300, and I used that as a basis of comparison and education.  One key fact is that this 3M device delivers 185 liters of air per minute.  You mentioned that you would sterilize air by mixing it with soap or alcohol.  Right off, we can eliminate the alcohol idea, evaporated alcohol vapor (that can’t be separated out) would not be tolerated at levels able to kill virus, I believe.  Even with soap, I worry about vapors from evaporation or incomplete separation in a centrifuge separator, being inhaled.  Even if substantially less than 185 liters would be adequate, say 90 (?), aerosolizing enough of a soap like product for this volume, mixing with air for an adequate amount of time, and then completely separating out this product at such high flow rates just doesn’t sound workable.
I like the UV light idea better, I found a UV-C sterilizing bulb that consumes only 6 Watts of power that perhaps could sterilize air flowing at such a high rate (???).  It only costs $3.01, so that’s affordable.  If you go this way, I don’t see that you could treat exhaust air with the same bulb, mixing intake and outflow takes much higher flow rates needed to dilute expired CO2 and allow enough O2.
I think with the trillions being spent on vaccination, you will find this a tough sell, even if you manage to overcome the many practical issues that will come up with adequate sterilization and affordable production.  Plus, people don’t want to wear a mask, let alone a hood, so that is a real issue.
I think your best chance of success would be to come up with a more affordable alternative that could be used in ER’s and stockpiled for future pandemics, but funding sounds like a challenge.
Sorry I’m not more excited, but that’s what I think at this point.


I see you already started your fund raising process.

To bring it to the commercialized Stage you might have to go through lots of haird
It is not easy to bring a concept to make it commercialized especially this type of extreme sensitive worldwide pandemic situation.
I hope your prototype model can be done soon, Selecting the final materials to be used are very important,
You should not mention in the Go fund me about the plastic Hood used costs only five cents each, you should just say “little cost” because you’re not certain what will be the final material Yet.? it has to be safe and pass many tests because there’s a lot of liability issues you have to consider,
I will think of more to share-

Anyway wish your success!

‘I have the same idea as your friend Vincent. Think the easiest would be modifying an existing PAPR system. Something like this:, but add your own disinfectant system. For mass acceptance, the whole thing need to be of lighter duty. If mass production of this is possible for $1000, US government can provide everyone with one for 400 Billion dollars, which is less than amount spent fighting this now. However, with the political climate, I just don’t see majority of people would wear this even if received for free from government. I still think a wet system would be too difficult to easily make into personal device.
For the “marketing release” you would need to add some pictures or drawings in order for people to better visualize this. I think another way to do this, instead of having personal protection system, is to modify existing HVAC system for all the indoor facilities, such as restaurants, mall, theaters, etc. If the virus can be effectively eliminated in the HVAC system, it would make indoor activities much safer and I think would help greatly in reduce the amount of transmission.’

Large Barn Doors

Eco-friendly large barn doors are taking on a whole new look and are a more sustainable solution for indoor and outdoor applications while commanding a unique stylistic approach to contemporary architectural design. The best extra large barn doors are emerging as featured presentations in all types of structures from residential and commercial to hospitality and industrial venues.

This new approach to the modern barn door is creating a stir as simple design of the traditional wood sliding barn door is now able to incorporate exciting characteristics that far surpass the simplicity of your grandfather’s farmhouse sliding door by incorporating this new generation of large architectural barn doors.

So, what makes this superior modern barn door so different from the sliding farm door of yesteryear?

While they may look similar, the large barn door hardware is much more sophisticated, but the biggest secret of all is what is found deep inside the best large barn doors of all time. If you were to look inside, you would find a patented substrate specifically designed to build the ultimate large barn doors.

Inventor Peter Sing is responsible for discovering and manufacturing this unique hybrid composite door core found inside the best modern barn doors today. Sing’s core imbues each barn door with astounding characteristics which cannot all be found in any other type of barn door, anywhere on Earth.

For instance, if your modern barn door has Sing Core inside, you will possess a door which is

  1. Eco-friendly
  2. Lightweight
  3. High strength
  4. Solid as a rock
  5. Fully insulated
  6. Warp-free
  7. Guaranteed 50 Years

Large Barn Door Problems

If you were going to make a high-end large barn door for a demanding client or visionary contemporary architect, you would have to hire a door engineer with the ability to design sliding barn doors which could be built to architectural specifications. The goal is to have an end product, a large barn door, which will not warp, fail, or require regular ongoing maintenance to keep it operational over time.

If the large barn door was quite oversized, say anything over three-and-a-half ft. wide and 7 ft. tall, you would find some extreme goings on inside such a door. There would likely be some type of welded steel interior framing and other heavy inserted in an effort to keep such a big barn door from warping, a pretty toxic approach to trying to solve the problems associated with large barn doors.

This is the biggest complaint with failing large barn doors: They warp. And warping barn door, if they are warped enough, will cease to operate, and if they are very heavy, this causes extra stress and strain on both hardware and the structure itself.


Large Barn Door Solutions

Thanks to Sing and his patented inventions and patent-pending solutions there is a way to make a lightweight high strength modern pivot door which can be guaranteed not to warp or fail for 50 years. There is no other way to accomplish such a feat without Sing Core inside.

Eco-friendly Large Barn Doors

Sing’s manufacturing facility is nestled in the pristine Pacific Northwest, where ecological approaches to building and creating almost anything is of profound importance to its inhabitants. So, Sing’s factory uses the best of both worlds, basic traditional woodworking craftsmanship and advanced cold-press technologies which use very little energy consumption. Sing also uses formaldehyde-free adhesive and responsible use of natural and recycled materials, plus being so lightweight makes them easier to ship around the world using less fuel than other barn door manufacturing methods, assuring Sing’s products have an extremely minimal carbon footprint.

Lightweight Large Barn Doors

Sing’s patented and patent pending technologies empower his True Flat Team to create these amazing hybrid solid composite cores which weigh a fraction of other solid wood-based structure cores. Lighter weight barn doors mean lighter weight hardware and less stress and strain on the structure. This prevents the need for constant ongoing maintenance to the barn door, a huge savings over time.

High Strength Large Barn Doors

You might not need bulletproof barn doors, but you will enjoy having lightweight large barn doors that are stronger than steel pound for pound. Sing’s large barn door core material is independently rated at 660+ PSI and is featured inside some of the highest security doors and impact doors in the world.

You can see that Sing’s panels are so strong that the inventor can stand in the middle of this one-inch-thick 13 ft. panel with little or not deflection. That is an effective strength demonstration.

Solid as a Rock Large Barn Doors

Sing’s patented and patent pending door core technology is based on his solid hybrid composite invention which is basically a vertical grain torsion box panel where the grid which would normally be left empty is filled wall to wall with recycled rigid foam insulation. Once assembled and cured they can take a beating, and unlike other doors can easily be repaired to full structure strength if breached, which is more sustainable than replacing the whole door.

Sing says, “Kick any standard stile and rail and it will break. Kick my door an you will break your leg!”

Fully Insulated Large Barn Doors

Inherit in Sing’s large barn door core invention is full insulation throughout which offers huge advantages to not only end users, but the sound proof door and refrigeration door manufacturers who rely on Sing to provide them with the insulated substrate to make the best rated lightweight large barn doors fully formatted for sound deadening and climate control.

Warp-free Large Barn Doors

And Mr. Sing is the King of the Warp-free large barn door. All hanging barn doors move according to changes in the environmental elements which surround them, and to make matters even worse, this is more problematic when in use as an exterior door, where one side is facing a structure’s interior, while the other could be exposed one hundred present to the weather.

Sing proudly guarantees his large barn door cores not to warp, bend, twist, or cup for a very long time, in fact, 50 times more than any other door manufacturer.

Large Barn Doors Guaranteed 50 Years

Unprecedented in the industry Peter Sing fully guarantees his large barn door core not to warp, bend, twist, or otherwise fail for 50 years, including structure & lamination. Nobody has ever dared to go there, and Sing who supplies the biggest and best door companies in the world with warp-free door core for all their oversized doors says, “If I couldn’t do it, you would have heard about it by now.”

And they all say the same thing,

“It’s the only way to do it.”

For if there were any other way to make a lightweight warp-free door, you know these companies would do it themselves, but they rely on Peter Sing’s patented innovations to provide what would otherwise be impossible, so they can better serve their clientele.

Should all your doors have Sing Core inside?

Dutch Door

What is a Dutch door?

Sometimes called stable doors, half doors, and double-hung doors, a dutch door is an exterior entry door that is cut in half, and the top section is hinged to open separately from the bottom. A popular rural look, these doors allow the top half to be opened for ventilation while keeping the bottom half closed to keep in children and pets.

Dutch doors offer a unique rustic look that can bring a ting of nostalgia to your kitchen door, patio door, or other exterior door design.

What is the purpose of a Dutch door?

Dutch doors allow their top section to open independently of the bottom. In essence this allows the door to function as a window, for ventilation and cooling, while keeping the lower portion closed to children and animals.

Likewise, in modern design inclusion of half doors in a design offers the opportunity to connect interior and exterior spaces while maintaining a delineation and element of protection for the inside.

Modern Dutch Doors

SingCore’s slab style construction opens the way for a modern style dutch door. The hallmark of modern style is clean lines and clear shapes. Further, our wood grain panels offer warmth of real wood in either wood stave or veneer.

Blow your friends away with a steel or aluminum skinned dutch door for that high tech finish.

If you can dream it, then we are able to make your dutch door dreams a reality. Other skin options include, paint grade plywood, veneer ready (apply your own styles and rails), HPL, plastics, ceramic ready, stone ready, and more.

Are Dutch doors energy efficient?

Although dutch doors do offer one extra seam, with proper weather stripping they can be just as efficient as other doors.

Additionally, SingCore dutch doors come with our patented foam “honeycomb” core which provides extra protection from sound and the elements. Need high efficiency doors? Ask about our high density urethane foam option for double the thermal protection of our regular professional grade panels.

Can I cut a SingCore door in half?

Our SingCore panels may be cut in half using typical wood working tools. You will encounter foam, wood, and possibly a small amount of aluminum depending on the style of panel. In order to finish the expose edges, you would need to route out the core from inside the skin, and glue in new strips of wood to seal the end.

However, at sing core every panel we make is custom to order. We are more than happy to build dutch door panels directly to your size and specifications. Don’t bother cutting your door in half, when you can have the right panel ready made delivered to your shop or job site.

How much is a Dutch door?

SingCore panels are sold by size, and so a dutch door will be close to if not exactly the same price as a regular door of the same size. For pricing and a free consultation on your next project, request an estimate today.
