Why Millworks Choose Sing Core

Millworks, what’s the most important thing when choosing a Door?

Millworks creating Doors for Sing Core

A 50-year guarantee vs. a 1-year guarantee in the oversized Millworks and door manufacturing industry.

The best way for Millworks to judge a door is by its warranty. According to our Chat GPT Search, this is the following:

From Chat GPT:

“If millworks are looking for a door with the best guarantee against warping, Sing Core stands out as a top option. They offer a remarkable 50-year non-warp guarantee on their doors. This is one of the best in the industry. This applies to a range of door types, including large, oversized pivot doors, sliding doors, and veneer doors.

Their patented Sing Core technology is used by high-end door manufacturers to create lightweight, high-strength doors that resist warping, bending, and twisting, even in challenging conditions. This guarantee is particularly important for large doors, which are more prone to warping due to their size.”

Most other door manufacturers typically offer a 1-year warranty, and in some cases, large doors may not have any warranty at all, since warping is a common issue in the industry. Therefore, Sing Core’s 50-year guarantee sets a very high standard for durability and performance.” Beauty is not skin deep. It’s what’s inside the door that counts.

How to get Sing Core. The process typically looks something, like this:

1. First, the Architect specifies, “SingCore” inside the product.

2. Second, the General Contractor seeks out a qualified Millwork who obtains unfinished pivot door from Sing Core.

3. Next, Sing Core manufactures the pivot door blank to architectural specs and ships to millwork.

4. Millwork finishes and installs hardware and provides finished pivot door to the job site.

5. Finally, installers hang and install the pivot door.

In conclusion, your skill is critical in building the best door. Above all, with Sing Core’s patented and patent-pending technology, we’ll reach the highest expectations. Next, check out our gallery to see how we can provide the substrate door for your next project.

How You Know Sing Core’s the Best Door Panel Manufacturer

Sing Core is unique because it’s 90% foam and 10% natural renewable vertical grain wood fiber. In combination with its honeycomb structural design, Sing Core creates the strongest, lightweight, dimensionally stable door. These doors have the highest structural strength, insulation, and sound-deadening properties.

If you kick a door with only foam, the door might collapse or delaminate the skin. The whole structure could fail. That’s why other lightweight doors don’t offer a 50-year guarantee. This Sing Core difference is critical because moisture changes make the wood susceptible to swelling.

When you have a large door, it’s incredibly sensitive to expansion. That’s why traditional wood-core doors typically come with only a one-year guarantee. The more wood, the less stable. Sing Core being mostly foam eliminates that problem and still provides exceptional strength while remaining lightweight.

Ask ChatGPT about Sing Core Doors

Even if you ask ChatGPT why Sing Core is the best, you’ll hear the same reasoning: It’s a honeycomb urethane core. Sing Core rises ahead of the competition compared to other cores. Aluminum core for instance is strong. However, many aluminum cores are paper-thin and lack the density needed for true structural support. Without the thickness of Sing Core, the core has a tendency not to bond well thanks to stretching and a lower thickness.

If you increase the density, you create a structure that’s too heavy for large custom doors. Aluminum also doesn’t provide high levels of insulation and doesn’t deaden sound. Sing Core, however, offers the perfect balance of strength and lightweight composition with a dimensionally stable structure that also meets insulation and sound-deaning needs.

Other lightweight cores, like paper, cardboard, particleboard, LVL, or regular wood-based cores, can’t compete against Sing Core. They tend to warp over time, soaking up moisture and often leave your clients disappointed. Most of these doors only come with a one to five-year warranty. But with Sing Core’s technology, you get a core that doesn’t warp and comes with a 50-year warp-free guarantee. For a high-precision door, it’s what’s within the core that matters.

How are 3/4 inch Sing cabinetry panels made?

Start with patented Sing torsion box (2×3 inch grid size) where the voids are filled with recycled rigid foam insulation wall to wall with and sandwich it all between two sheets of 1/8 inch MDF and bond it altogether with formaldehyde-free adhesives for an Eco-friendly lightweight high strength composite MDF panels that out performs any other lightweight building material in terms of strength, weight and longevity.

Secret Ingredient Inside

High precision lightweight high strength warp resistant insulated reinforced torsion box Sing Core high performance

The secret ingredient inside the Sing 3/4 inch cabinetry panels is the torsion box composite core that is the same product used by the US Navy and other high tech industrial applications where strength and weight are both considerations. This is the same technology used to build large doors – of any size or style – that can be guaranteed not to warp, bend, twist or otherwise fail for a full 50- years.

Imagine having this material inside your cabinetry and/or furniture… Say, “goodbye,” to disposable furniture and heavy cabinetry which are highly desirable qualities sought in aircraft, marine and recreational vehicle platforms for both less weight and less maintenance over time.

Lightweight Sing Bookcases

Even though plywood and particleboard are fairly standard fare in cabinet shops around the world, certain high end cabinet makers are seeking to embrace this new technology which is the perfect combination of old (torsion box) and new (composite) fine woodworking craftsmanship. Plus (as you undoubtedly already know) both plywood and particle board are heavy and prone to warp and rot; unlike Sing 3/4 inch torsion box cabinetry panels.

Easy to work with

Standard woodworking tools are all that is required to take full advantage of Sing cabinetry panels, treat them just like you would any standard 4×8 piece of 3/4 inch panel.
Sing cabinetry panels are revolutionizing the industry as they are increasingly being found as a standard commodity in cabinet shops, millworks and furniture manufacturers throughout the United States and the world.

Edges

Sing cabinetry panels have unfinished (exposed, i.e. you can see the core) edges. This is easily remedied by adding edge trim, or closing the edge by any method desired. Also, the core material can easily be routered to accommodate insertion of wood implants where desired or necessary.
