When you’re in search of the best door possible it is important to compare Sing Core doors to expensive alternatives. We say,

  • Heavy does not mean strong
  • Lightweight does not mean weak
  • Most expensive does not mean higher functionality

Sing Core doors give you features that cannot be duplicated in more expensive doors. Doors costing ten times the cost (or more) of Sing Core doors cannot provide the features and benefits of Sing Core and only Sing Core doors are guaranteed:

  • Lightweight
  • Stronger than steel lb for lb
  • Structurally guaranteed for 10 years
  • Eco-friendly

Even though Sing Core doors look exactly like the more expensive import doors, a side-by-side comparison of these flush wood doors reveals important differences:

Based on 30 in. x 80 in. x 1 3/8 in. doors.

Exterior material MDF MDF

Sing Core doors are extremely lightweight in comparison but so much stronger…

Kick the Door

You might think that the heavier and more expensive door would give you a sense of security, but these doors can easily be kicked-in. On the other hand, if you try to kick the sing Core door, you are more likely to break your leg than the door. Plus, having a pre-insulated door with sound-deadening qualities help to improve your quality of life and Sing Core doors are guaranteed up to 50 years, but are built to last for centuries.

Easy to Repair

Sing Core doors feature a patented cellular torsion box structure core material combined with stress skin that can be easily repaired. For example, you could cut a hole in a Sing Core door with a chainsaw. This hole can easily be repaired with Sing Core material and stress skin to match. The Sing Core door strength will be returned to 100% structural integrity.

The Best Doors Don’t Have to be Expensive

That’s just one example to prove that the world’s best doors Do Not have to be the world’s most expensive doors. No one can match the features and benefits of the Sing Core door. See our comparison of Sing Core material to other materials.
