General Specifications

10 ft x 5 ft x 1.75 in Standard Sliding Door Specs

Professional Sing Core doors are manufactured with patented Sing Core material as the base interior substrate of the door with patent pending composite stiffeners to strengthen and prevent door warping over time. 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 your choice of EPS or urethane foam insulation, stiffeners are added to support the performance of the door for specific end use application(s). Other foam insulation material is available in various forms depending on your specification. This default on this professional birch ply door 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 1/4-inch 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 on this professional series is a wood-grain birch ply material. Bonding agent used in adhesion of the entire composite material is formaldehyde-free.

Interior Blocking: Solid wood implants are inserted as lock blocks or anchor points. Also additional stiles (vertical wood implants) or rails (horizontal wood implants) can be positioned at any desired location inside the door. (Note: Depending on your expectations, solid wood implants should be supported by at least 12 inches of Sing Core material to maintain true flatness.)

Delivery: Reasonable care is taken to ensure safe transportation of your Sing Core door from factory to your location including proper crating to protect the natural beauty of your door during transport.

Storage and Protection: Store your Sing Core door in an upright position and allow to acclimate to room temperature following shipment receipt or prior to finishing or installation.

Preparation: Per manufacturer’s specifications, ensure that door frame openings are constructed plumb, true and level prior to installation. Select fasteners of adequate type, number and quality to assure proper function.

Installation: Installer shall be specialized in the installation of the type of work that is associated with the project and will comply with manufacturer’s installation policies and procedures to ensure proper end use.

• Verify that sliding hardware and latching assemblies operate freely and correctly

Finishing: The finishing of the Sing Core professional sliding door is the responsibility of the client due to the product being delivered in unfinished quality unless specified otherwise in writing. Any sealing must be in accordance with manufacturer’s specifications to protect against a variety of environmental conditions as necessary.

• Edge-band edges to encapsulate Sing Core (see T-molding)
• Seal all 6 surfaces with two coat minimum on operable panel(s)
• Finishing or re-finishing must be completed following acclimatization and installed within 7 days
• Avoid finishing after rain (or damp) or during periods of higher than average humidity
• At least once a year, conduct periodic inspections of coating to ensure no door components are exposed
• Reseal the surface as necessary

Machining: Sing Core doors are easy to work with in the millwork shop for CNC machining or on-site for finishing, sawing, sanding, cutting and fastening. No specialized skills or equipment is necessary, other than standard woodworking tools. Treat Sing Core doors just like you would any other standard door blank.

Strength Performance: Patented Sing Core has an unsurpassed strength as compared to other lightweight substrate materials tested at 660 PSI (based on 2″ x 2″ grids and 3/4″ thick) for superior structural integrity and is resistant to warp, twist and crack when compared to other materials.

Light Weight Performance: Sing Core weighs much less than other traditional building materials, as much as 50% less; or more, as little as 4 lbs. per sq. ft. yet sustainable and true green technology.

Insulation Performance: Standard Sing Core professional doors feature built-in EPS insulation value of R3.5 or urethane at R6.5 rating per inch, or more, depending on architect’s specifications and the utilization of other rigid insulation material(s).

Acoustical Performance: Sing Core standard doors have a natural sound-deadening quality for noise control. Standard sound transmission class (STC) is 30*. Additional noise control specifications can be met at the behest of the customer or designer and must be noted in advance.

Eco-friendly: Sing Core is manufactured using natural wood fibers, no formaldehyde, or toxic chemicals, is created using less energy than any other core material with little or no waste. The structure of Sing Core is 100% renewable (nature-grown) clean fiber and/or recycled material.

Warranty: Sing Core professional manufactured doors are structurally guaranteed and warp-free for 50 years under normal conditions.

* 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.
