In a world where anything could change in a minute you might wonder if this is one of those moments in time when your ideas about any large barn door could shift radically, thanks to inventor Peter Sing’s invention, as we discover how his revolutionary patented large barn door core is changing how doors are built. And, yes, we said large barn door. That means any large barn door of any size, up to 50 ft or more.

Sing’s patented and patent-pending technologies empower architects, door engineers, millworks, custom door builders, and the biggest and best large barn door manufacturers to build any extra large barn door of any size, and guarantee them not to warp for 50 years.

In most cases, barn doors are inexpensive, and the sliding barn door hardware is easy to find. Basically, any do-it-yourselfer can build a diy large barn door by hanging a 4×8 sheet of plywood from any sliding barn door hardware which is readily available from any hardware store.

This is why you find them erected on farms and other industrial settings because it doesn’t take a lot of engineering to figure out the basic details of any large barn door project.

Basically, in a diy large barn door application, all you need to know is the size of the opening, and determine whether you can obtain or make the large barn door panels the size to fill the opening.

Once you have determined the size of the opening and materials, the weight and width of the barn doors will help to determine the hardware which will be required to hang said barn doors.

This is a fairly simple and inexpensive method of dealing with openings you’d rather be able to secure to some degree if your expectations are low, and if the size your barn doors are exceeding the limitations of available building materials (i.e., 4×8 or 5×10) then it can be increasingly difficult to create panels large enough that will offer an acceptable degree of longevity.

Large Modern Barn Door

Barn doors are expanding greatly in size and application as modern interior designs are featuring a vast variety of barn door ideas as expressed in contemporary architectural designs the world over. No longer are sliding barn doors limited to closing and accessing large barn door openings, industrial, warehouse, or aerospace applications.

Today, it is not uncommon to find modern barn doors in living rooms, kitchens, bathrooms, bedrooms, dens, garages, and even featured as sliding front doors for a unique greeting and main egress impression for visitors to unique homes.

In large front door applications, the barn door hardware is located inside the home (not outside as in an actual barn site) or hidden within the adjoining wall spaces, like large front entry pocket doors.

That said, you will be finding more and more modern barn doors springing up all over your property’s exterior and interior locations, and when they are large sliding barn doors, the only way to assure their remaining straight and true is to have them built with patented and patent-pending Sing Core solutions embedded within the doors themselves.

Sing’s patented large barn door core is the only way to build fully insulated Eco-friendly lightweight barn doors of any size or material which can be guaranteed to remain warp-free, including full structural warranty, for 50-years.

How to Build a Large Modern Barn Door

To understand how to build a large modern barn door that can be backed by a 50-year warp-free guarantee is to understand the basics of patented Sing Core. Sing Core starts with a basic small grid torsion box matrix built of natural vertical grain wood fiber (many times more rigid than standard horizontal grain). Instead of leaving the torsion box voids empty, they are filled wall to wall with rigid recycled insulation. Finally, this is all enclosed using formaldehyde-free bonding agents between stress skins, and this is the basis of the embedded power of warp-free Sing Core.

The remainder of the large barn door is built around this revolutionary building material, the brainchild of inventor Peter Sing.

Oversized Wood Barn Doors

Of all wood sliding barn doors, oversized wood barn doors are the most problematic due to the natural tendency of wood grain to change in response to the environmental conditions surround the barn doors themselves.

For instance, a knotty alder sliding barn door is going to present problems due to the prevalence of knots throughout the barn door’s surface which greatly increases the tendency to warp. In the case of a knotty alder sliding barn door, Sing’s True Flat Team will go to work to further enhance the patented Sing Core substrate by inserting various anti-warp technologies to effectively counteract any of the knotty alder’s potential movement or warping.

High Precision Modern Barn Doors

This is how you create the highest precision sustainable modern barn doors known to man, with patented and patent-pending Sing Core inside. No other substrate is so lightweight, with stricter tolerances (Sing Core is +/- .006 in.), non-warping, fully insulated, and stronger than steel pound for pound.

While such high precision may not be necessary to fill the opening of a barn or warehouse, modern barn door applications, especially as an exterior front entry door, require higher levels of accuracy and consistency to effectively protect and fully separate the two main adjoining spaces.

When used as a front door, it is imperative for the modern barn door to remain straight and true to properly seal and protect the interior from the exterior environment. And if the main access door were to warp, it could compromise the ability of the entry door so much as to render the barn door unusable.

50 Year Large Barn Door Guarantee

If you have your large barn doors built with Sing Core inside, you can be assured to enjoy 50 years of low maintenance fail free service. Sing guarantees every large barn door not to warp, bend, twist, cup, or otherwise fail (far meeting or exceeding AWI standards) for 50 years, including full structure and delamination.

That’s why the biggest door companies, best mill works, and most prestigious custom sliding barn door manufacturers in the world say,

“There’s no other way to do it.”
