sing sandwich 4x8x1 4 ft x 8 ft x 1 in torsion box panel lightweight high strengthPricing for Homeowners

Many educated homeowners demand that their trade professionals use Sing Core products in their home projects.  (See our Homeowner’s page for more information.)
Regrettably, we are unable to provide patented Sing products for retail or directly to homeowners as we only support architects, millworks and door companies. See full apology.

If you do not have a millwork or door company in mind, please check out this online map to help find one near you.

Note: We do not sell complete finished doors to retail customers. No hardware, no finishing. We only support other trade professionals, like millworks and door companies who make doors with Sing Core inside look beautiful and perform elegantly. If you are a retail customer, please contact your architect, designer, contractor, door company or millwork and tell them you want, “Sing Core inside.”

Since Sing Core is a manufacturer, we do not provide customer support for retail clients. If you are looking to build a tiny house, carriage door, etc., please seek out qualified trade professionals (such as architects, general contractors, mill-works, door manufacturers, and woodworking professionals) for help using Sing Core products for your project. Sing Core is the manufacturer of our patented invention and as such we are not qualified or staffed to teach all the uses for, or handling of, Sing Core building materials.

Sing Core does make the best reinforced structural insulated panels (RSIP) for use in applications such as walls, floors, ceilings and roofs; however, we offer no support or training or guarantee for unskilled users of Sing Core products.

Note: We do occasionally offer products direct to the do-it-yourselfer, like our free Tiny House e-book. Although we may provide the materials, we offer no “how-to” support to the DIY enthusiast except that which is available via our Tiny House FAQ (frequently asked questions) and our free tiny house e-book.
