Custom Door Window Glass Openings

Applications -> Building Components -> Doors -> Custom Door Lites

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.

1-piece-true-flat-10-light-door-vs-13-piece-stile-and-rail-french-door-sing-american

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.

5 BE CREATIVE

Enter the Sing American Door, the door inspired by the traditional French door but allows you to have complete control of the design process. The Sing American Door is our most popular of all the Sing Doors that we manufacture.

There are many other reasons (below) that explain the advantages of Sing American Doors vs. other conventionally manufactured doors.

A new technology for manufacturing doors – especially doors with glass – is used by all major high end millwork professionals and some leading edge door manufacturers. It starts with a patented Sing Core flush door, then cut window openings in any shape or size without compromising the strength of the door.

french-door-americanized-custom-design-glass-anywhere-7-inchesSing Outside the Box

Embrace your creativity and let your imagination run wild!

Now you can sing with us and have your own Sing American Door customized to have glass openings custom cut to your specifications.

We see so many different and unique custom requests and styles that are unrestricted. We love enabling our clients to make their custom door dreams come true and so enjoy this creative process.

Plus, Sing American Doors have the super-strong benefits of being a solid structure without any weak connecting points to compromise your door and are resistant to warp, twist and rot over time, designed and constructed for lifetimes of maintenance-free enjoyment.

Eco-friendly Sing Doors are manufactured with our true green patented process using 92% less precious raw materials, with much less labor, energy expended and waste than any other door.

Sing American Doors come to you ready to install the glass and finishing by your door installer, or we can have the door finished for you.

For optimal strength and resilience we suggest that you keep your window light opening locations within a 7 inch door perimeter, and you enjoy extra safety and security due to having an elegant solid door without weak spots that is fully customized by you.

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.

handcrafted-true-flat-high-end-eco-friendly-french-door-lightweight-high-strength-singHigh-end Sing Doors

We make the most exclusive, precision high-performance door for our most exclusive clients. To achieve these spectacular results each door is custom crafted by hand. The Sing American Door is the economical alternative allowing you to duplicate the results of the custom handcrafted Sing door, saving you $1,000 or more on each door.

Sing American Doors are proudly made in the USA for you.

Any Surface Material

While French doors or doors with windows are normally considered to be wood or wood grain finished, with your Sing American Door, you can specify what material your door is made of, like aluminum, ceramic, concrete, glass, fiberglass, metals, plastics, steel, even fire-resistant mag-board and bulletproof Kevlar. So whether you are looking for an interior door with glass or an exterior door with glass, even a steel entry door with glass or any other type 1 metal door with glass, you can be certain that your door with glass insert will outperform any other door with glass insert and method. When you care to have the best interior door with glass insert, your Sing American Door with glass panels is guaranteed to be the best affordable solution.

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.)

You, our client, your dreams and desires are our priority. Let us help you achieve your American dream with your Sing American Door.

How to Make a Sing Door with Glass

Applications -> Building Components -> Doors -> Sing Glass Inserts

Patented Sing Door Methods

Sing American Doors are versatile and customizable. Every order is custom designed with the client’s project in mind. Each door is constructed using methods that specifically cater to our customers’ individual needs. We construct our doors using the following methods: pole barn grade, paint grade, wood grain grade, and plank grade.

How We Build Our Doors (The Best Method – Sing Torsion Box Panel Method)

This is how to build a 12 foot tall Sing American Door by using sing panels and cutting the light open and installing glass… ‏

Step 1 – Apply Glue to the Skin

Step 2 – Build Solid Wood Frame

Step 3 – Install the patented Sing honeycomb torsion box core & press on the skins.

Step 4 (optional) – Cut hole for window and prepare window trim.

Step 5 (optional) – Install glass and finish the door to desired look and function.

Step 6 – Install the door onto jam.

Whether you are looking for an interior door with glass or an exterior door with glass, even a steel entry door with glass or any other type 1 metal door with glass, you can be certain that your door with glass insert will outperform any other door with glass insert and method. When you care to have the best interior door with glass insert, your Sing American Door with glass panels is guaranteed to be the best affordable French door solution.

Method 2 – How We Build Our Doors (The Second Best Method – Stile Rail)

 

On the left are patented Sing honeycomb stile and rail. On the right is veneer (walnut) ready for gluing onto the patented Sing honeycomb stile and rail.

 

Apply glue to our patented Sing honeycomb stile and rail.

 

Press veneer to patented Sing honeycomb stile and rail. Most honeycomb panels cannot handle the high pressure and temperatures of the hot press, Sing honeycomb can.

 

Stile and Rail after the veneer has been pressed on.

 

See how straight the patented Sing honeycomb stile and rail are, yet they are still incredibly strong and lightweight.

 

Drill holes to accept dowels.

 

Doweled and glued.

 

Router out the end if hardware is to be installed

Stained and ready for glass and installation.
