Sing Core has a long history of solving the most challenging obstacles in thermally insulated doors made of any flat material that can be guaranteed true flat and stay flat for 50 years. Our doors are highly unique one-of-a-kind solutions that are used in the most exclusive structures around the world.

That is, until now. Thanks to our relationship with Lowe’s Home Improvement, there has been an sharp increase in the demand for standard Sing doors that could be used in more traditional residential applications at a price that is in-line with other quality doors that are commercially available to the public but do not have all the characteristics that are unique to Sing doors.

Introducing Standard Sing Doors

Sing Core is raising the standard of all doors by offering Sing Standard Doors that are available from Lowe’s and any other participating retail outlet, door company or lumber supply. For virtually unlimited door options, see even More Doors.

Sing Doors May Look Like Other Doors

Even though Sing Standard Doors may look like other doors (because we can duplicate the look and feel of any door style) looks are only skin deep. The real difference between Sing doors and any other commercially available lies deep beneath the skin in the heart of the door itself. The core value of Sing door core imbues the door with a set of unique characteristics that cannot be found in any other types of doors.
