Measuring at 2.25 inches thick, this is the most premium quality door money can buy.  Due to the patented and patent pending SingCore technology, this 15.5 foot long, 3 foot wide, 2.25 inch thick pivot door is straight as an arrow, better than AWI standards.

Many Ways to Build It

Depending on your budget, you have a number of different options when you opt to go with Sing Core.

  • You can order substrate only and apply your own soft wood or hard wood veneer (economy option)*
  • You can supply your own veneer for us to apply
  • You can choose solid wood edge banding
  • You can choose our highest end selection, where we provide the veneer and apply it in nearly any soft wood or hard wood, such as, Mahogany, Walnut, Maple, White Oak, Alder, Cedar, Hemlock, Fir.

How to Build the Perfect 16 ft. x 3 ft. High Precision Warp-free White Oak Door

You start with patented and patent-pending Sing Core inside sandwiched between American-made A/B plywood with solid oak around all four edges.

After pressing, trim the edges, then add another 1” x 2.25” solid oak to the edges. Sand it to perfection then hot-press 16th-inch white oak veneer, then all you can see is solid white oak. Beautiful.

The result is a perfectly flat lightweight white oak door that is stronger than steel pound-for-pound, weighing in at a mere 220 lbs.

 * Professional veneering can be very tricky. If you are getting substrate from Sing Core and having your millwork (or someone else) apply the veneer, be certain to affirm that they have the expertise to apply the veneer appropriately. We use the highest level of professional veneer professional and techniques. We can guarantee our veneering, if you have veneering done off-site, it is their responsibility to do it correctly. A faulty veneer could jeopardize your Sing warranty.
