General Specifications

Standard insulated flush door pre hung door marine grade plywood fiberglass aluminumStandard 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 recycled 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.

* 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.

Sing Timber

What is Sing Timber?

Sing Timber is a large mass of wood that can be milled to any specification. Its versatility is exemplified by wood shops who saw the large timber masses in more specific smaller planks as needed. Sing Timber can come in 12 inches wide by 12 inches tall and 96 inches in length, or you can get it already cut-to-order as Sing Hardwood.

Sing Timber can be broken down into any thickness and width, to create your own wood plank. You do not have to inventory all size of plank just by sawing Sing Timber to the desired thickness. You can slice the Sing Timber to any desired width, all you have to do is to seal the deal by gluing an exterior skin on the fresh sawed side to finish your new plank.

How Can I Use Sing Timber?

Sing Timber is manufactured with a heart of Sing Core,  coverd with exterior skins on at least two sides form a large box like timber mass. It  can be sawed horizontally, sanded and glued to form a smaller wood plank. It will create any dimensional wood and it cabn be covered any hardwood species, metal, plastic or even cement to create a new generation of ulitmate lightweight, high strength products.

Sing Timber is Better than Hardwood

Sing Timber’s Sing Core makes this the only hardwood material that is better than hardwood, for a integrous building material that is just a beautiful as solid natural hardwood with far superior structural integrity.

Sing Timber’s high-strength is due to Sing Core that is less expensive than solid hardwood. When Sing Timber is produced, the energy savings are impressive, as the actual production process uses less energy, man hours and equipment usage and produces little or no waste. Sing Timber is also sonstructed of low cost, renewable natural wood fiber and recycled EPS foam. Patented Sing Core is many times stronger than most of the core materials used in modern aircraft with much less weight and a fraction of the cost of core used in the aircraft industry. The cost can be less than 10% of the inefficient core used in aircraft design.

Compare other type of honeycomb or core materials , sing core is the only core physically and cost effective to build Sing timer which will turn to hundreds of different products for many industries.

How does Sing Timber work?

Simply stated, Sing Timber can be used as any regular lumber, cut to fit your appropriate application, as in shelving, Or you could add a solid wood edge to enforce the strength and add fastening anchor point for mechanical fastening.

When working with Sing Timber with a router, be certain to attach wood strips to the area to be routed, as the exterior wood surface along the face is minimal.

Sing Timber is versatile

Our most popular format in Sing Timber is the 4×12 in 8- and or 10- foot lengths. It can be used as a stand-alone post and/or beam as is, or (here’s the exciting part) can be turned into so many different products for multiple applications. For example…

Sing 4×12 lumber can be easily sliced into alternate widths and thicknesses to suit your needs. No need to make multiple trips to the store to pick up the lumber you need, simply slice Sing Timber 4x12s into the size that you want on-site; Perfect for the millworker or ambitious do-it-yourselfer.

By sawing the sandwich panel cross the Sing core to form two pc of sing sandwich without skin on one side than add new skin or add new solid wood to build a two sandwich panel or two Sing panels at different thickness. Sing Timber is easily broken down into any dimension wood plank or hardwood. Sing Timber can be easily sliced to substitute for standard 2×4 lumber.

How Do You Add Hardwood Stave?

It is easy to add a sardwood stave to any cut or sawed section of Sing Timber.

Firstly, all you have to do is to sand the surface of your freshly-cut exposed Sing Core section of your plank.  Apply urethane glue or white glue to the smooth surface, then press. It’s that simple to turn a selection of Sing Timber into your own Sing Beam that is just as visually impressive as solid wood, but lighter weight and stronger than steel pound for pound.

Sing Timber is Strong and Straight

It is very hard to find straight hardwood without bowing, twisting or cracking.  Solid hardwood is heavy, and hard to work with.

Sing Timber is an eco-friendly solid wood composite material with a patented Sing Core interior that results in lumber that is straight and flat, unlike any other building material on the planet.

Sing Timber is also available pre-cut as Sing Hardwood.
