Depending on application, different substrates are used to give a countertop thickness and strength. It also adds support and valuable sound deadening to our custom countertops.


MDF– Standard for indoor residential applications.

Medium Density Fiberboard rivals the affordability and versatility of plywood and similar engineered wood products. Unlike real wood, MDF has no knots, grain, or warping, and it has a smooth surface.


MDO– Used for Outdoor and Marine Applications.

Medium Density Overlay is produced with a high-quality thermosetting resin-impregnated fiber surface bonded to one or both sides under heat and pressure to create an exterior-grade plywood panel. MDO is manufactured with waterproof resins that meet or exceed all veneer-grade, adhesion, and construction requirements.


Medite FR– Fire rating Applications.

Medite FR is made with a formaldehyde free adhesive system and is designed for critical applications where Class 1 flame retardant material is required. Medite® FR has a low flame spread and smoke development as well as extremely low VOC emissions.

For both residential and commercial applications, we encourage our customers to order their stainless steel and copper countertops with our factory applied wood or metal substrates for a turn-key application.
