Sing Solution Considerations

What should you consider when seeking out the Sing solution?

1. Dimensions Affect Price

 

Sing Core can build anything that can be panelized, from large pivot doors to hangar doors and panelized structures such as warehouses or even Sing Log Homes. Very large panels or walls can reach enormous proportions and can be made modular for near seamless assembly on site. Other factors which affect the overall price of your project will be,

2. Importance of Surface Material

 

The skin material used on your panel’s exterior greatly affects how the substructure is built. Basically, the greater the tendency for the exterior surface material to move, the more of Sing’s True Flat engineering is required to create a hybrid substrate which will counteract the panel’s tendency to warp, bend, twist, or otherwise create a challenge in the field over time.

3. Sing Core Inside

The core of the panel in question can come in many different variations besides the patented and fully insulated, reinforced vertical grain torsion box core to match the high precision performance expectations of your project. Many considerations are made to determine the size of the patented structure grids as well as integration of patent-pending counter-warp materials to achieve desired results.

4. Thickness

Thickness of your panel and each of its features affects everything. For instance, it is much easier to keep a panel straight and true the higher the percentage of patented Sing Core is inside your panel proportionally. Even if your surface material is natural wood, your client might desire 3/8” thick material, when using 1/8” material is far more effective, and the difference is not noticeable on the end product.

All of these things play a part in the design and engineering of your panel in terms of

Giant Factory Door Extremely Light Weight

A. WEIGHT

The overall weight of your custom panel(s) is determined by the sum of all the components which are necessary to create a one-of-a-kind solution which meets your required specifications. The greater the amount of Sing Core inside your panel, the less it will weigh and the stronger it will be.

B. STRENGTH

No other substrate in the world is more lightweight or high-strength than inventor Peter Sing’s Sing Core, which provides for a solid composite core based on Sing’s patented insulated and reinforced torsion box structure, which is stronger than steel pound for pound (660+ PSI). By doubling the among of patented Sing Core, you multiply the strength of the panel four times.

C. WARP-FREE

Besides being Eco-friendly and made in the USA, patented Sing Core is the only substrate which can guarantee your panel will not warp, bend, twist, or otherwise fail. In fact, this revolutionary building material enables the best door companies in the world to build large doors of any size which can be guaranteed warp-free for 50 years (a first in the industry).

BUDGET CONSIDERATIONS

Sing solutions for problems and challenging projects can be costly, but they may also be extremely affordable depending on your performance expectations.

If you are on a budget and flexible about some of the elements of your design, there is a good chance that Sing’s True Flat Team may be able to reengineer a solution for you that will both meet your budget and your performance expectations.

1. Paint Grade Door

2. Wood Grain and Wood Stave Door

3. Hardwood Plywood Door

1 Paint Grade Door

Our most popular door blanks are paint grade, and can be made to your specs including surface materials of,

  • Birch ply (most common)
  • Wood plywood
  • MDO
  • HPL
  • Other material, as specified

 

2 Wood Grain and Wood Stave Door

Besides paint grade for the surface, we also provide solid wood stave laminate on both sides of the sliding door. Wood stave is easy to work with and will last. Your Sing wood stave door will be more high precision than solid wood door (less warping, and twist and crack) due to Sing Core’s extremely high tolerance (+/- .006 inch) and, rigidity and high strength (660+ PSI) and professional grade wood grain and wood stave doors are certified and guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

Sing Core provides hot-press ready door blanks to door manufacturers who add wood veneer on both sides of Sing door blanks which are made of Luan skin or marine grade plywood sandwich with patented Sing Core in the middle, solid wood around 4 edges and wood block implants where needed for hardware.

oversize-panel-edge-glued-together-planks-5ftx10ft Sing-Hardwood-Panels-Variety

Note: Veneer has to be handled very carefully every step of the way during production (we prefer to let the millworks handle this delicate procedure) and it is easy to damage by users over the years (but wood stave can be easily sanded and repaired).

We offer a very good price for wood stave doors, the cost is not much more than wood veneer doors.

3 Hardwood Plywood Door

We could make door with hardwood plywood as an effective way to make super large doors that you can stain any color. Up to 4×8 doors have no seam, but by orienting the grain horizontally, you can achieve a nearly seamless presentation on really big doors or extraordinary size.

Available in any available wood species, most common are Sapele, Oak, and Maple ply.

Sing Hardwood ply door has excellent strength, yet is lightweight, features good insulation and better sound deadening qualities than solid wood plank doors.

Sing Panels with Plumbing and Wire Chase

sing-panel-horizontal-embedded-cable-chase-wire-chase-plumbing-chaseCustom Sing Panels can be manufactured to your architectural specifications which may include special chases for plumbers to route hot and cold water feeds via plumbing or electricians to run electrical wiring, communications and security through a patented Sing panel.

Surface mount conduit and exterior chases can be added to Sing panels as they are, though many users of our patented insulation reinforced torsion box core prefer to use embedded wiring chase of for water supply pre-installed plumbing chase.

Embedded Chases

Embedded chases can be placed at specified locations prior to manufacturing your Sing panel to meet the specific requirement of the job at hand, accommodating communications center needs or the special needs of inplant offices, clean rooms, temporary warehousing, watch towers, guard shacks, portable classrooms, spa expansions, home theaters or any application where running utilities, like electricity, wiring and/or cables or plumbing inside and through your Sing panel may be advantageous.

Common horizontal chases are specified at 16 inches and 45 inches from the base, while the most common location for a vertical chase is in the center of the Sing panel. Regardless, every Sing panel is custom manufactured in our factory, and we can have your wire chase or plumbing pre-installed within your panels at any location specified.

How to Specify Wire Chase Locations

sing-panel-embedded-cable-chase-wire-chase-plumbing-chaseIt is easy to have your embedded chases pre-installed at the proper locations. All you have to do is to be certain to disclose the precise locations and sizes of your wire chase (plumbing chase or cable chase). We will provide you with an architectural drawing of your panel before your custom Sing panel is built for you to confirm the chase’s location.

No Loss of R Value

To preserve the R-value of your Sing panel it is advisable to have the cable chase filled with spray foam insulation after pulling the wires or routing the plumbing through the embedded channels. Likewise, if a channel is not used, it should also be filled with foam insulation prior to final assembly, unless insulation properties are not necessary for your application.

Panel Chase Options

Although many options abound for electricians and plumbers to install access to services, another popular method includes running cable, wire and plumbing through panel connectors that run the length of your standard Sing panels, or alternatively running services through the floor.

Many creative options are available for adding access to water, electricity and communications without having the necessity of pre-installed chases being embedded in your Sing panels.

Economy Chase Options

An emerging value-minded approach to inexpensive reinforced structural insulated panels is to obtain two economy 1.5 inch Sing Panels from your local Lowe’s Pro Desk. Prior to gluing them together to make a single 3 inch panel, simply router out where you want your chase channel to be, then adhere the two panels together. This is an inexpensive option discovered by price conscious tiny house builders.

* Note: STC rating varies according to size, thickness, skin, and other factors. Sing Core does not rate doors, although we are fortunate enough to have one of the best sound testing labs in the world, here in the Pacific Northwest. If you require a specific STC rating, Sing Core can build a door to your architectural specifications and have the resulting door tested at our rating facility for an official rating.
