Why Millworks Choose Sing Core

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

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.

Get Things Done Right the First Time

Millworks and door manufactures are rightfully wary about building and installing large or oversize wooden doors. That’s why the top millworks in the country choose SingCore for challenging projects where they need to get things right the first time.

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.

Unmatched Door Panel Precision and Strength

Traditional doors can struggle with stability, especially over time. The trade-offs between strength, weight, and precision often force millwork to compromise—not with Sing Core. Our patented honeycomb core delivers exceptional flatness and warp resistance, ensuring every door you specify remains perfectly aligned and easy to install.

This strength-to-weight ratio also makes Sing Core doors easier to handle and less prone to causing stress on hardware, especially in larger applications where other doors would be too heavy or prone to sagging.
