Google Best Pivot Door

If you want to find the best door in the world for you next project all you need to do is to use the best tool for finding the best doors, such as:

Google search pivot door

Google search pivot door

If you’re looking for the what constitutes the best doors, then you might search for the most expensive door. You will find that the door companies which can make the most expensive doors which outperform all other doors in terms of weight, strength, and longevity are the hardest to make. That is, unless you know the secret.

Best Door Secret

Pivot doors are problematic because they only have two points of contact whereby the pivot door is operated and anchored by the pivot door hinges.

Hinge doors can be secured by multiple hinges, even a full length piano hinge which anchors one whole side of the door completely. Even so, with one side fully anchored, a large door will warp, bend, twist or cup, causing it to fail. A warped door will compromise the door seal and may not be able to allow the door latch to secure properly.

High End Pivot Doors

Pivot doors rely only on those two pivot points, one on the top of the door, and the other opposite it on the bottom of the door. It is imperative for a functioning pivot door to remain straight and true, or else you cannot operate it properly.

Only the best pivot door companies can make a high-end pivot door which can perform over time without failing due to door warp.

50-year Warp-free Guarantee

All you have to do, is to contact the top pivot door manufacturers on your search results and ask them if they offer a large pivot door with a 50-year guarantee.

If they do, these doors will all have Sing Core inside.

With Sing Core inside your pivot door, it will be lightweight (a fraction the weight of other solid core pivot doors), and high-strength (at 660+ PSI, stronger than steel pound-for-pound).

You also have the added benefit of having a pivot door which is fully insulated for climate control and sound deadening capabilities (Sing Core can be found inside the most efficient soundproof doors in the world).

You Can Laugh or Cry

When you discover the secret of the most expensive high-end doors, you might start to laugh, but before you start laughing, think about this:

You might be crying, if you make the wrong decision, and find yourself in possession of a weak door which may fail prior to when you might have expected.

This is why most large door manufacturers will exclude large doors (over 7 ft tall and 3.5 ft wide) in the door schedule from the warranty following installation. Chances are they will start to fail at the next change of season.

Then you might reason (as many have) that if Sing Core can make the best doors in the world the most valuable doors in the world, then Sing Core could make anything better, and it does.

Doors and So Much More

Entire homes have been made of Sing Core, which is available in post and beam and panel formats, changing the way homes are built, including all the interior and furniture inside a Sing home.

Sing Core makes everything better and its Eco-friendly nature makes everything more sustainable over time.

Sing Stile and Rail Doors

The Sing-style approach to stile and rail doors is a horse of a different color amidst the age-old door industry. Sing stile and rail doors are lighter in weight and stronger than steel yet made of nearly any flat building material available, not matter how they’re built.

Sing Stile and Rail Look

Our most sought-after stile and rail manufacturing method produces a stile-and-rail-looking door from a solid composite Sing door slab which feature alternating wood grain orientations on the door surface to emulate the look and feel of a stile and rail door without any weak spots.

The resulting Sing Stile and rail door made of a solid door panel is the strongest, lightweight, most insulated, Eco-friendly door proudly made in the USA.

Sing Stile and Rail Construction

Even among the most tried and true stile and rail door manufacturers, they know that the only way to build a large stile and rail door which can be guaranteed not to warp for 50 years, is with Sing Core inside.

Rather than build a stile and rail looking surface and applying it to a solid slab of Sing Core, traditional stile and rail manufacturers prefer to use stile and rail components with Sing Core inside.

Basically, this means that all the stile and rail components are manufactured by Sing Core in building material formats which are very similar to our post and beam configurations, and/or furniture panels. These are assembled by your favorite stile and rail door builder just as they would any traditional wood stile and rail door components.

Sing Stile and Rail Advancements

You might be surprised what benefits can be enjoyed by custom door makers who construct their doors using patented Sing products. This new, revolutionary door building material is

Lightweight Stile and Rail Doors

Weighing in at a fraction of other solid core doors, Sing stile and rail doors can be very lightweight, even if they are very big doors, without threatening the longevity of the door’s performance over time.

High Strength Stile and Rail Doors

Stile and rail doors made of Sing Core are incredibly strong. Rated at 660 PSI, Sing Core is stronger than steel pound for pound, thanks to Peter Sing’s patented solid composite torsion box core substrate, incredible unsupported spans are possible, enabling doors with Sing Core inside to outperform any other lightweight door.

50 Year Stile and Rail Guarantee

Professional grade Sing Core has such a high precision tolerance (+/- .006 in.) and withstands just about any variance in conditions across the board, that these are the only door which can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years, including full structure warranty.

Eco-friendly Sing Core

Using Sing Core is the Eco-friendliest way to build a sustainable door, which is made with a smart combination of minimal natural and recycled material combined to create this revolutionary door core material which is the lightest weight and highest strength way to build doors of any kind.

New Revolutionary Door Technology by Sing Core

We offer our services to support door manufacturers in building stronger, lightweight, high precision and warp-free (AWI warp standard) insulated doors using our patented and patent pending Sing Door Blanks and Sing Stile and Rail frames.

Sing Core’s specialty is assisting to create incredibly large and extremely wide door panels which door manufacturers can utilize to build the most challenging high-end doors.

Large Quantity Production Runs

We can also assist in the high-quantity production runs for doors using our facility to pre-build base doors which might otherwise create a bottleneck for common door manufacturers. We love taking over the assembly line bulk of your large door orders with rapid turnaround times.

You choose your method of building your Sing Core door blanks:

1. Sing Door Core Panel

You specify the length, the width, and thickness of your Sing door blank, built to your specifications. You determine the insulation value and skin material, and we do the rest. The Sing door core panel method is the strongest and best Eco-friendly insulated door solution for any sized door, even large oversized wooden doors, available in almost any style.

2. Stile and Rail Door Frame

For our customers and their clients who prefer the standard design of stile and rail doors, we provide the manufacture of a stile and rail formatted frame made of any combination of Sing panel, post and beam configurations to create the most sustainable stile and rail doors, which are finished by only the best millworks and custom door manufacturers. Sing Core provides the most significant improvement to stile and rail technology (besides automation) in the last 100 years to create the strongest, lightweight, most high-precision, and warp-free performance in the history of the door industry.

Doors of Almost Any Style Could be Made with Sing Core Inside

1. Pivot Doors

Pivot doors are the highest and best use of Sing Core because for the most part, pivot doors are quite large in size and are often much thicker than a standard door. If your intention is to feature a real wood finish, you know you’re going to be in trouble, that’s when the warp-free attributes of patented Sing Core shines through as the only way to build a large wood door which can be guaranteed to offer warp-free performance over time: 50 years, guaranteed, on professional grade doors.

2. Sliding Doors / Pocket Doors

Sliding Doors often present problems when they are very large due to their sensitivity and tendency to move, bend, or cup in response to changes in the environment, for which Sing Core is the perfect solution.

Large bypass sliding doors are likely to deface, scar, or otherwise damage themselves if they are not kept straight and true by being built with Sing Core inside in advance of bypass door failure.

Pocket doors, which are the most problematic of all sliding doors, because they hide within a cavity are highly benefited from being built with Sing Core inside. If warped, the finish of the door may be compromised as it brushes against the frame or cavity’s interior, and if it cups or bends too far, may become lodged either inside or outside of the pocket unable to open and close as a door. Sing Core keeps them straight and true.

3. Hinged Doors

Hinged doors are for the most part manageable even when facing a certain degree of warp, which is normal in normal sized doors. Problems arise when doors are very large, especially if over 7 ft. tall or 3.5 ft. wide. Any movement or change in the door’s being compromised is increased exponentially in relation to the dimensions of the door. Not a problem with Sing Core’s professional door blanks.

Diverse types of hinged doors, such as French doors, sliding folding doors, front entry doors, and carriage doors (among other types of hinged doors), all present varying challenges when migrating from the drawing board to the real world, and Sing Core makes the difference.

Door Sizes

While Eco-friendly insulated Sing door blanks could be used in doors of any size, the efficacy is maximized in door performance in any door over 7 ft. tall and 3.5 ft. wide. This is why you find Sing Core inside the largest doors in high-end homes, businesses, and industrial sites, because it’s the only way to build a large door which can remain straight and true, regardless of the size of the door, while still remaining lightweight.

Door Shapes

Since every door slab manufactured by Sing Core is likened unto a one-of-a-kind piece of art, architects and designers are free to create a door of any size and shape using any available flat building material.

Sing door slabs can be created to accommodate any shaped design in any thickness, and so it goes for any shaped light cutout for glass openings.

Skin Options

Sing door slabs are available in almost any skin you want, limited only by flatness (surface material must be flat), ability to be laminated, and availability.

Some examples include, paint grade plywood, aluminum, brass, cement board, cold rolled steel, concrete, diamond plate steel, fiberglass, FRP, galvanized steel, glass, hot rolled steel, LVL, Masonite, stainless steel, any wood species including exotic species, and many more.

Our most common specialty includes the cold pressing of solid wood stave to our patented and patent pending core material, resulting in natural wood doors that can be guaranteed to remain warp-free for 50 years. Unheard of in the wood working industries. We also supply high end millworks with hot-press-ready warp-free substrates to apply their skins to.

Light Openings

Available in any size and any shape, based on your drawing(s).

STC-rated Sound Doors

We assist in the creation of sound reducing or sound proof doors which can be STC-rated at our local world-renowned pro sound testing lab. Some typical composite configurations include combinations of steel, sheetrock, MDF, and other materials to achieve the sound proof results to meet your specifications.

Fire Proof Doors

We build fire proof doors to your specs and can have them rated at the fire-rating facilities selected by our fire proof door clients.

And that’s just scratching the surface…

Don’t Get Stuck with a Fake Sing Door

Does Your Door Have Sing Core Inside?

If your door has Sing Core inside it can come with a full 50-year warp-free guarantee. No other door can be guaranteed like that, unless it has Sing Core inside.

It is rare, but there have been occasions when a door has warped, when someone thought it had Sing Core inside, but it did not.

For instance, last year, an architect in Florida specified a large wooden door with Sing Core inside. The contractor contacted Sing Core and received an initial price quote.

Nine months later, we received a call from the architect who had been contacted by the building department that reported that a large wooden door with Sing Core inside had warped.

We searched our records and could not find any record of the job. We did discover the initial price quote request from the contractor who must have found a different way to make the large door.

Your large door with Sing Core inside comes with a certificate of authenticity and guarantee.

Be forewarned, if your large wooden door doesn’t have Sing Core inside, you can expect it to warp.

Make sure your large doors have Sing Core inside.

How to Join Sing Doors

Gorilla polyurethane glue is an effective glue for joining Sing panels. We recommend consulting the glue manufacturer website for instructions on use of the adhesive. For Gorilla Glue, look here.

Failure to follow the joining instructions or the manufacturer adhesive instructions could void the
warranty on your panels.

Before you begin

Attention: Please read all instructions before starting to assemble your panel
Follow the acclimatization instructions before joining panels

1. Lay Your Door Panels Flat

It is crucial that all of your panels are resting on a flat surface and are completely level. If you attempt
to glue the panels together against a wall, or any way other than flat, you will end up with a crooked
joint and “warped” door.

The first step to join a Sing Core sectional door is to lay the panels on a flat surface.

For very large door panel assembly please place straight guide beams on top of sawhorses so the
bottom of the panel can be accessible.

Assemble on a Flat Work Surface

To ensure best results, it is critical that you assemble your panels on a flat surface. If you do not
have a work surface large enough, the best way is to build your own.

The best way to level your work surface is to lay guide beams end to end, then use shims to level
each beam. It is important to lay your beams perpendicular to the joints on your panel.

Uneven Floor Surface

For wider panels you will need more rows of beams to distribute the weight more evenly and to ensure flatness of the joined panel. Make sure to level each additional row of beams with your initial row that you have already leveled. Once your work surface is level, you are ready to join your panels.

 

2. Glue and insert Your Biscuits or Spline into the Edge of One Panel

Each biscuit and slot are precisely cut to join with the greatest strength. After applying the glue to the slot and biscuit, do not use an excessive amount of glue. If the air is very dry a light misting of water can help the bond and cure time of the glue. Carefully push or hammer each biscuit lightly in place into the edge of one panel. Tap in with a rubber mallet.

 

3. Joining the Panels

The final step in joining your panels is to press the sides together. This can be accomplished a variety of ways, including gentle application of a sledgehammer, a few ratchet straps, clamps, or any other means you have of providing joining force.

 

4. How to Clamp at the Join

When you want perfect alignment for very high tolerance applications, it’s best to sandwich each joint with a straight guide temporarily during the gluing process. Polyurethane Glue expands during the cure process. You will be ensuring the glue does not expand and bow the joints.

You will need:

Flat boards to clamp or screw to (depending upon the size of your panels); Clamps or screws to create pressure on the joint while the glue cures; and a flat surface. If your panels are so large that you need to use rows of screws to clamp the joints you will need to putty the holes before finishing.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

—Old Instructions—

 

When your beautiful new Sing Core door sections arrive, it is important to take the time to glue the door together properly using polyurethane adhesive. Although Sing Core panels are guaranteed warp-free, we cannot guarantee work done on site. Failure to properly follow these directions may result in a poor final product.

Sing Splines Don’t Crack

Sing Core uses our patented core material as a spine to join several panels on site. Unlike solid wood, the stability of the core material means that there is no danger of cracking or splitting of the seam at the join location.  When Sing Core fabricates your door as a single panel it is almost seamless.  When a door is splined, it is not as high precision as a single panel due to the tolerance of glue, which is roughly 0.01-0.02 inches.

Join on Site in Three Steps

1. Lay Your Door Panels Flat

It is crucial that all of your panels are resting on a flat surface and are completely level.  If you attempt to glue the panels together against a wall, or any way other than flat, you will end up with a crooked joint and a “warped” door.

The first step to join a Sing Core sectional door is to lay the panels on a flat surface. Any flat clean surface will work. For very large doors we like to use two straight beams laid on the ground along to hold the top and bottom of each door segment.

2. Insert Your Biscuits or Spline into the Edge of One Panel

Each biscuit and slot are precisely cut to join with the greatest strength. Carefully, push or hammer each biscuit lightly in place into the edge of one panel. Then your panels are ready for joining.

3. Joining the Panels

The final step in joining a modern sliding or pivot door is to press the sides together. This can be accomplished a variety of ways, including gentle application of a sledgehammer, a few ratchet straps, clamps, or any other means you have of providing joining force. Once joined, the door is strong and secure, built to last, and can be finished and installed as any other Sing Core door.

How to Clamp at the Join

When you want perfect alignment for very high tolerance applications, it’s best to sandwich each joint with a straight guide temporarily during the gluing process.

In order to make your process easier, Sing Core offers construct custom true straight guides for your application and ship them with your order. These guides are made with the same high precision core material as our other products and offer superior ease and performance.

Specify you would like clamping guides when you place your order and we will gladly include them for you.

Pivoting Pocket Door

Among the pivot door industry, the millworks, custom pivot door builders, and every major pivot door company, the new buzz words in the world of pivot doors includes the request for high end pivot door to have, “Sing Core inside.”

You might wonder why the trend of contemporary architects and designer are specifying their pivot doors, especially if they are large pivot doors, have, “Sing Core inside?”

The reasons include the attributes of patented Sing Core that are transferred to the pivot door making the lightest weight pivot door (a fraction of other solid pivot door cores, that are also the strongest (independently University tested at 660+ PSI) insulated pivot doors every built.

Thanks to inventor Peter Sing’s patented pivot door core material, any pivot door company can build a large pivot door that can be guaranteed to remain warp-free for 50 years. Pivot doors with patented Sing Core inside are the only pivot doors that can be covered by Sing’s 50-year warp-free guarantee.

Unique pivot doors of all kinds can be built with this revolutionary new pivot door core material, including but not limited to the following pivot doors:

Pivoting Pocket Door

A modern pivoting pocket door presents certain challenges for architects and designers, such as being heavy in weight if it is a large pivot door which swivels and retracts or is stored in a pocket door cavity within a wall. The pivoting pocket door is basically a pivot sliding door which pivots and slides into the concealed pocket. If slide and pivot doors have the slightest warp, bend, or twist they can become inoperable or might be lodged inside the pivoting pocket door’s recess.

Having Sing Core inside ensures the pivoting pocket door will remain faithfully straight and true for the life of the door or 50 years, even though it was constructed to last for hundreds of years.

Pivot Front Door

A pivot front door is also an architectural challenge if it is large, and all the best pivot doors are large pivot doors because the larger they are, the more likely a pivot door is going to fail due to warping. If one side of your pivot entry door faces the structure’s interior space and the other side faces the exterior, exposed to the weather 100%, you’re going to experience a warped door.

 

Exterior pivot doors do present a problem for the end user and an opportunity for ongoing pivot door companies who specialize in long term maintenance and repair over the life of the door. A well-hung pivot door with Sing Core inside will outperform any other commercial door, hands down. Even if it is among the family of,

Wooden Pivot Doors

Wooden pivot doors present the most problems with warping due to the nature of the wood to move according to the varying climate conditions or change of seasons. Seasonal warp is expected for wooden pivot doors of all kinds, whether they are exterior pivot doors or internal pivot doors.

Patented Sing Core is the only way to build a wooden pivot door that doesn’t warp with all the elegance and charm of solid timber pivot doors but at a fraction of the weight saving you money in pivot door hardware and maintenance over time.

Thanks to Sing Core you can have a large pivot door made of any available natural wood material, which is even a ecologically sound use of exotic wood to create the most impressive exotic wood pivot doors, which is subject to availability, of course.

Pivot Doors Prices

Sing Core’s pivot doors prices will have you expecting to pay more than a traditional pivot door, though in the standard range of high end custom pivot doors. As our favorite architectural door designers know, when you client demands the best pivot door made, it must have Sing Core inside your pivot door.

And while your custom pivot door might represent those among the higher pivot doors prices, you can be proud to have an economical pivot door investment which will pay you back in savings in maintenance, repair, and replacement costs because your Sing pivot door can be guaranteed for 50 years.

Pivot Door Systems

Sing Core is known around the world for providing the best pivot door systems, but the truth is, we don’t actually make the world’s best pivot door systems. Who actually makes our doors the best pivot doors in the world, is the pivot door company, custom pivot door manufacturer, and millwork who makes our patented pivot door core material look so good after they’ve finished and installed these magnificent masterpieces.

Pivot Front Doors for Sale

If you really want a pivot door with Sing Core inside, all you have to do is to contact your local custom pivot door manufacturer, millwork, or wherever you find pivot front doors for sale and make sure you tell them you want Sing Core inside your pivot door.

A Low Cost Alternative Way to Build Very Large Sliding Doors

Although not as tough as our original one piece door designs with a 50 year guarantee, our segmented doors still come with our patented Sing Core structure inside and carry a 5 year warp-free guarantee. And, they can be sold at a much reduced price.

In the past, very large and oversize specified doors were often made as a single piece and shipped whole to the contractor for installation. This is particularly true of very large pivot doors and sliding doors. With modern door construction techniques pioneered by Sing Core large doors can be produced and shipped to the customer in several pieces. These segmented doors pass on savings to the customer while maintaining the highest quality standards for warp free door construction.

Benefits of Modern Segmented Door Construction

Building a door in sections provides numerous benefits without compromise in strength, lightness, and flatness:

See Them Come Together

More Efficient to Build

Constructing a door in smaller sections makes the door easier to handle in the factory and easier to produce in general. Having more manageable sections leads to quick and efficient construction, at a cheaper cost. Doors constructed with our modern sectional approach pass on savings to the customer.

Cheaper to Ship

Doors cores produced in sections are built to be convenient and cheap to ship compared to a door built in one piece. This may reduce shipping costs payed by the customer to receive their door purchase.

Easier to Handle

Very large doors constructed in segments conform to common sizes. When you receive the door at your site handling it in segments is usually more natural for workers used to traditional sized doors than and 4×8 materials than handling an extra large door. Leaving joining the door until it reaches the site cuts costs and saves time all the way from our factory to your building site.

Strong and Stable

Sing Core doors shipped in sections and assembled on site maintain the highest standards for strength, lightness, and straightness. At Sing core we guarantee warp-free performance of segmented doors for 5 years.

How to Assemble a Sing Core Segmented Door

Assembly of a modern sliding door constructed using Sing Core technology without any specialized tools and equipment.

1. Lay Each Panel Flat

The first step to join a Sing Core sectional door is to lay the panels on a flat surface. Any flat clean surface will work. For very large doors we like to use two straight beams laid on the ground along  to hold the top and bottom of each door segment.

2. Slide a Spline in to One Side

Each spline and pocket are precisely cut to fit with strength. Our products are built with our 5 year warp-free guarantee in mind. Simply push or lightly hammer the spline in place on one side of the joint. Then your panels are ready to be fit together.

3. Joining the Panels

The final step in joining a modern sliding or pivot door is to press the sides together. This can be accomplished a variety of ways, including gentle application of a sledge hammer, a few ratchet straps, clamps, or any other means you have of providing joining force. Once joined, the door is strong and secure, built to last, and can be finished and installed as any other Sing Core door.

Cracks in Wood Stave Doors

Here, at Sing Core, we get calls all the time about problems associated with wood stave doors, especially if they are large, oversized wood stave doors. These problems, such as bending, twisting, cupping, and warping should be celebrated as wood’s natural tendency to adapt to it’s environment. Unlike other synthetic materials, wood stave is sourced from a previously live authentic tree unique unto itself, a valuable resource in the eco structure of our planet.

A tree is a living, breathing part of our environment, made of the same atomic stuff we are, a sort of shirt-tailed cousin, which survives consciously for years by continuously adapting to its environment.

Even following the harvesting of a tree’s wood, the wood’s independent slices fight for their right to continue to acclimate and survive, expressing their individuality and uniqueness.

That’s why designers, architects, and pretty much the rest of us love the look and feel of real wood. We appreciate the look of it, the design of the individual expression of the tree’s growth rings, and it makes you have a comfortable sense of being home in a virtual hug from Mother Nature.

When wood stave (natural slices of wood) is applied to a door core material, the wood will move to accommodate the environmental challenges and circumstances which it is presented with.
In the case of cracking wood stave doors, the surface crack is the nature of the wood to adjust to the tension of the door’s core. The wood is still trying to provide you with the best door ever, so it sacrifices the surface finish and moves to accommodate the needs of interior core of the door. A crack-resistant finish will result in the tension being spread over a larger surface area, developing a warped or cupped door which can be more problematic to deal with than a surface crack.

Natural wood stave doors will move, warp, bend, twist, and crack, unless they are uniquely engineered with the proper composite materials to result in a wood door that does not move.

Sing Core provides architects, custom door manufacturers, and millworks with the best structurally sound composite door core which is lightweight, insulated, dimensionally stable, and stronger than steel pound-for-pound. Properly laminated materials, including the application of the natural wood stave to the patented torsion box composite core in concert with patent pending straighteners, delivers to clients a natural wood stave door which can be guaranteed to remain warp-free, including a full structure warranty, for an unprecedented 50 years.

A cracked natural wood surface door is likely due to a moisture problem, which varies in intensity between interior wooden doors and exterior wooden doors. Any wood door needs to be properly acclimatized to avoid cracking and excessive movement, also contributing to a wood’s tendency to move would be considering the way in which the wood was sliced, cut, or sawn.

Wood stave is a much higher concept in wood-faced doors than wood veneer as wood veneer which is not susceptible to cracking or warping, it is very thin and cannot easily be repaired when slightly damaged. Wood stave is a thicker natural wood product which can easily be maintained using basic woodworking skills.

How to Measure a Warped Door

How can you tell if you have a warped door or not?

There is an industry standard method of determining whether your door is warped or not.

To determine whether you have a warped door or not you will need a length of string (longer than the length or height of your door) and a measuring stick or tape measure.

a) Tape one end of the string to the edge of the door and the other end to the opposite edge of the door.

The string should be straight. If there is a gap between the string and the door’s surface, you may have a warped door.

b) Measure the gap between the string and the door’s surface area.

If the gap is greater than ¼” your door is warped (according to AWI standards for 1-3/8 to 1-3/4 inch doors 3’-0” to 3′-6″ x 7’-0”).

c) If the length exceeds 7 ft. AWI standard applies to any 7 ft. section. Apply string to any 7 ft. span.

Contact your door maintenance company and send them two photos.

d) [1] Photo of the length of the string which shows as much of the door in its entirety, or at least from one end of the string to the other. Then [2] a closeup photo of your measurement of the gap.

Armed with these two photographs, which can easily be emailed to the millwork or door maintenance company of your choice, the recipients will be able to determine how best to approach the repair or replacement of your warped door.

You might consider replacing your warped door with a professional door which has Sing Core inside which can be guaranteed not to warp, bend twist or otherwise fail so as to avoid this pitfall in the future.

For more information, see: Door Warping vs. True Flat

Storing SingCore Doors

After you’ve received your patented Sing products, if you will have to store them prior to finishing and/or installation, try to store them standing upright, on edge, with plenty of space in between, to allow air flow. Do not lean them against a wall. If you must store them stacked, wrap in plastic and place one or two sheets of plywood underneath and on top of the stack of Sing products. This will help keep the entire stack similarly acclimatized while not in use, otherwise, you may have to re acclimatize the top and/or bottom Sing products later, when you are ready to use them.

 

How to Store SingCore Doors

What if my door with Sing Core inside is warped?

The same standard method of determining and measuring any door with Sing Core inside is used just like any other door (as noted above).

Contact Sing Core about your concerns about your door being certain to include the two photos as noted above.

If you have purchased a professional door with Sing Core inside, you may be the recipient of a replacement Sing door.

Note that upon arrival and un-crating of a door with Sing Core inside, a door may appear warped (and indeed it will be measurable). This is normal for a door which has been packed and in transit. Stand your door on its edge at least twelve inches away from any adjoining surface area, allowing it to acclimatize for up to 72 hours. Measure your door again and you will find it to be straight and true. If not, document for warp (as above) and contact Sing Core.

In the event that a professional door with Sing Core inside is warped (which is highly unlikely) your help in determining the cause of the door’s warping is appreciated. Please assist documenting the chain of custody of your professional door with Sing Core inside, including the millwork or door company which finished the door, and the installers who installed the door, to help us insure your replacement door remains warp-free.
