CUSTOM WINDOW CUT-OUTS – ANY SIZE – ANY SHAPE

for door professionals  and  manufacturers

Introducing the new, “American,” French door.

Say, “Au revoir,” to the traditional French door that limits your design options, and say, “Hello,” to the new Americanized Sing door that is nearly limitless in your creative design possibilities.

The Sing American door is basically a Sing Panel (that can be any size) custom cut for your window lights (without compromising the strength) to achieve your desired results, and can even be used to duplicate the exact appearance of any other door (and have been used in antique restorations).

The beauty of the traditional French door feature is in the greater light presence due to greater glass insertion and represents the status of traditional values. But, as you know, if you have shopped for French doors, you are limited to few options as to the placement and size of your light openings for glass.

Compare Sing American Door solid one-piece design (left) to traditional 13-piece frame (right).

Up ‘til now, the only option for you, if you wanted an extraordinary French door, was to hire a high-end custom door craftsman or millwork to make your custom door to your specifications, even extremely big doors.

1 STRENGTH

Each Sing American Door features a one-piece Sing Panel construction with window light openings cut to your specifications, then install the glass. Traditional French doors are based on stile and rail design, which makes the door weak at the four connection points and all the joints in between the glass are the weakest points of your door.

2 SIMPLIFIED DOOR MANUFACTURE

The unique one-piece Sing American Door uses patented Sing Core as the foundation of the process in contrast to conventional French glass door construction which is solid wood, stile and rail or features a sandwich panel design with foam, wood based, paper or hollow core which does not have the strength of Sing Core (one kick will delaminate other cores and they will warp, while kicking a Sing door will break your leg and can be warp-free). See core comparison used in door and many other industries.

3 COST EFFECTIVE

Custom high end doors or even regular import panel doors and French doors are created laboriously via craftsman-like intense processes. Alternatively Sing American Door require a fraction of the labor cost. You could pass these savings on to your customer or have a better profit margin by promoting high quality, long lasting true flat doors made in the USA.

4 SAFETY

Sing American Doors are lightweight. It is safer for families that have children (with precious fingers and toes). Another safety concern is due to the possible risk of injury or breakage due to kicking glass at the bottom of the door. Many designers are looking for options of reducing the glass exposure at the bottom of the door without compromising the overall appearance.

The Sing American Door Secret

The secret is in the strength of patented Sing Core (click here to see Sing Core vs. other cores) that is 4-to-5 times the strength of aluminum honeycomb core used in the aviation industry. The superior compression strength (can be 700 PSI or more) and built-in insulation makes the Sing Panel the most high-performance door. Sing Core is 20-to-60 times stronger than the foam core found inside foam-core doors. A regular foam-core door is not strong enough to cut and support glass installation without reinforcement.

Doors made of Sing Core provide the possibilities of adding more trim and molding or the highest rating(s) for fire proof, bullet proof or sound deadening to build specialty doors with a designer look.

What is a French Door?

A French door is a door style consisting of a frame around one or more transparent and/or translucent panels (called lights or lites) that may be installed singly, in matching pairs, or even as series. A matching pair of these doors is called a French window as it resembles a door-height casement window. When a pair of French doors is used as a French window, the application does not generally include a central mullion (as do some casement window pairs), thus allowing a wider unobstructed opening. The slender window joinery maximizes light into the room and minimizes the visual impact of the doorway joinery when considered externally. Often, the doors of a French window open outward onto a balcony, porch, or terrace and they may provide an entrance to a garden. (Wikipedia.)

General Specifications

Standard Sing Core doors are manufactured with patented Sing Core material as the base interior substrate of the door. The Sing Core substrate material is created using a vertical grain natural wood torsion box design while the traditionally empty voids are filled wall to wall with recycled foam. The foam material is available in various forms depending on your specification. The default is EPS foam. Natural wood lock blocks are positioned at locations as necessary for locking mechanism placement or as anchor points. The core material is wood framed by 1 ¾ “ natural wood for finishing strength and attaching hardware. The torsion box is completed by adhering an exterior material (skin) according to your specifications. The default is a wood-grain (Luan) material. Bonding agent used in adhesion of the entire composite material is formaldehyde-free.
