Hinge Doors

Sing Core has been assisting the best high end custom door manufacturers create the most magnificent swinging doors using the best hinged door known. Only the best, most exclusive upscale architects, designers and ultra-custom door makers know if you want the best hinged door for the highest degree of precision, performance and prestige, you want your door to have Sing Core inside.

Hinged Door Warp-free Hinged Door Guarantee

Building a door with Sing Core inside is the only way to create a door that can be guaranteed not to warp, bend, twist or otherwise fail for 50 years, including a full 50 year structure strength warranty. While other doors may be guaranteed for 10 years, most or one or two years, if they are guaranteed at all. Doors over seven or eight feet tall are normally excluded from any warranty due to their tendency to warp the next season.

With Sing Core you can create Eco-friendly swinging hinged doors that are insulated, lightweight, high strength. No need to add extra door hardware to help keep the door straight over time (door manufacturers add extraneous hinges in an effort to keep the door straight). But warp-prone hinged doors, even if they have a full length piano hinge, still warp on the side that latches, and a door that does not operate and cannot be secured is not much of a door at all.

Airtight Hinged Door Seals

Maintaining a perfect airtight seal is of primary importance, plus the added insulation characteristics of any door with Sing Core inside increases climate control while adding sound-deadening qualities not found in other doors, especially in high end laboratories, industrial environments, commercial applications, and homes.

Superior Exterior Hinged Door Applications

Exterior hinged doors often cause problems (especially if they are over 7 ft tall) because one side of the door faces the interior of the structure while the other side of the door faces the elements.

Hinged Panel Doors

Panel doors are assembled of wood (or other material) with separate pieces oriented in cross grain patterns to help mitigate the potential door warping. While this method is somewhat effective, the resulting door does not offer much in the way of high precision, insulation, or performance, but they are pretty. The craftsmanship of a well-made stile and rail door is very elegant and the way the different pieces are joined together offers a certain intrigue when examining the door, especially if it is a wood grain door. But consider the Sing solution…

Sing Raised Panel Door

The Eco-friendly Sing raised panel door is a huge improvement over the traditional stile and rail door, in that it is extremely high-precision (+/- .06 in.) lighter in weight (a fraction of the weight of those solid wood panel doors), insulated for climate control and sound deadening, and stronger than steel pound of pound enabling professional raised panel doors with Sing Core inside to be guaranteed warp-free (will not warp, bend twist, cup or otherwise fail) for 50 years, including full structure warranty. No other door can do all that, and be so versatile.

While a Sing raised panel door can look just like a standard 6 panel door made via the old-fashioned stile-and-rail door manufacturing method, making a raised panel door with Sing Core inside is quite different.

The most important component of the Sing raised panel door is the patented Sing Core material which consists of a hybrid composite of vertical grain torsion box grid filled with rigid recycled foam insulations sandwiched between two stress skins and superiorly bonded with formaldehyde-free adhesive. This gives your door the strength and integrity you’ve always dreamed about. Install the door, and no worries about service calls due to door warp.

The Best Millworks and Custom Door Manufacturers

The best millworks and custom door manufacturers know that the only way to deliver a truly premium product to their high end clientele is to provide them with doors which they make with Sing Core inside, enabling them to guarantee their doors for 50 years, backed by Sing Core’s written guarantee.

The Best Flush Doors

Sing Core provides door manufacturers with the best door blanks and flush doors to be used as the best canvases to showcase the artistry and craftsmanship of the finest custom door makers in the world.

Again, if you want to make your Sing flush door look like a panel door, like, say a 6 panel door, the door artisan simply adds the 6 panels and trim to the door’s surface. This is a common approach, especially in door replacement of historically preserved architecturally challenging maintenance and upgrades.

Sing doors are often considered the best replacement doors, especially in exterior door replacement due to the weatherproof door’s characteristics.

Your flush doors with Sing Core inside can easily be modified by adding custom molding, trim or cutting custom lite  cutouts for glass installation in any shape at any location to achieve your desired results.

“How can I get doors with Sing Core inside?”

It’s easy. All you have to do is to contact your favorite millwork or custom door manufacturer and tell them what kind of door you want, including the height, width, thickness, style and look you want (you can even bring in a picture of one that you’ve found in a book, magazine, or on the Internet.
