If you are looking for a sliding door solution that gives you the SingCore sliding door advantages, like lightweight, superior strength, long life and flat, then you’ve come to the right place.With our commitment to sustainability you can have an American-made, eco-friendly sliding door that will last the test of time.


Every Job is Custom Crafted.

Remember, SingCore technology is completely customizable to your specifications as they are available in any length, any width and any thickness and bonded to any exterior finish.

Lighter doors mean less costly hardware.

When producing custom doors with traditional materials (wood, lvl, and other heavy materials), much of your costs will go into the hardware itself, which can cost over a $1000 for some doors. Opting for a Sing Panel saves on this cost, and also reduces labor installation.

Our professional and hot-press-ready Sing Panels are guaranteed for 50 years so you don’t have to worry about warp, twist or rot. This technology is solving sliding door design solutions for Presidents, Prime Ministers, Kings and the Pope, especially when the application calls for extra strength, oversize or true flat… without compromising weight for strength

Wood Stave vs. Wood Ply

Wood stave doors can be very costly to make, especially if you’re looking for a lightweight high strength solution for a warp-free guarantee for 50 years. Using Sing Core inside your wood stave door featuring wood planks from 1/8-inch to 1/2-inch will create more potential for warp due to the nature of natural wood grain. This is the beauty of the more economical wood ply option for building your wood door. Wood ply is far less expensive and has alternating grain orientation which also helps to keep the door straight. Wood plywood is just like any other plywood except for its featuring a particular wood grain predominantly on the surface, and it offers far more strength and reparability over time than a less expensive wood veneer. So, if you’re looking to attain similar visual results of a solid wood door at a fraction of a price you might consider having Sing Core inside your wood plywood door. Be certain to specify what type of natural wood plywood your want, if it is available, you can save thousands of dollars on your beautiful wood door. The most popular wood plywood features woods such as white oak plywood, maple plywood, oak plywood, mahogany plywood, walnut plywood, Douglas fir plywood, knotty pine plywood, and birch plywood just to name a few.
