Hawaiian door manufacturer sought out Sing Core in search of a non-warping exterior door solution for rigorous climate variances especially large oversized sliding doors and pivot doors.

During the free consultation, the manufacturer explains that large doors are known for warping top to bottom, but people don’t talk much about warping side-to-side, which makes it a constant struggle for latching and sealing the door. These are the constant issues that face the makers of large exterior doors.

The undeniable fact is, patented Professional Sing Core is the only way to build a lightweight, high strength non-warp door. And Sing Doors are guaranteed not to warp – top-to-bottom or side-to-side – for 50 years including full structure guaranteed also.
