Just to put the record straight.
We use whatever the client wants as carcase material, so cost wise it goes MFC, veneers, birch ply, veneered birch ply, Compressed rhino scrotums.
Most clents will be sensible and opt for a combination, such as MFC on basic cabinets with birch ply in wet cabinets (sink and dishwasher areas) and veneers in show cabinets (larders, worktop mounted cabinets, drinks cabinets).
MFC is a great product, we only use Egger, I can tell the difference with content when cutting compared to Kronorspan or other makes, much less binding on the saw and metal / waste content.
Why put veneers in a drawer pack carcase or a pullout bin carcase, much better to use the money else where.
But at the end of the day it's the clients budget. We do lots of birch ply and veneer kitchens.
P.S. so far no one has ordered a compressed rhino scrotum kitchen carcase.
