Thin Corian countertops--no plywood underneath possible?

Hi all,

A Corian fabricator I've been talking to about white 1/2" countertops said they usually install on top of solid plywood.

Is it possible to install Corian countertops directly on top of your cabinets, and leave only a thin edge exposed? I know a lot of Corian counters emulate the thicker look of granite or stone, but I actually really would live a 1/2" thick white edge. Possible?

I don't know about which solid state materials are stronger, or if they're all roughly in the same range. We also want to have a 10" overhang on two sides of a kitchen island (L-shaped counter-height bar) and if it's possible to do without supports, I'd vastly prefer that. I've looked into Hi-Macs a little but not much else.

Would thicker tops (Corian comes in 3/4" also) help the strength issue?

Your Corian fabricator is woefully mistaken. The first thing they teach you at Corian school is that solid underlayment traps heat and is forbidden.Strip underlayment only; plywood and/or MDF, not particleboard.

Corian may be installed directly on cabinets with or without an edge build up. Solid cabinet tops must be relieved.

3/4" Corian is obsolete. A 10" cantilever will need support, but it can be inconspicuous.

Thank you for helping me avoid a heart attack! Would large L brackets work for the support?

Google the Corian installation specifications for specifics, please.
