Our experience has been that we take out many particle board cabinet boxes that are falling apart. The door hinges and the drawer guides that are screwed into the particle board eventually give out as the screws wallow out (highly technical term there!) the holes. Possibly the newer products are different.

Our advice to clients is to purchase the best box they can based on their budget. We like 3/4" cabinet grade plywood, but 1/2" will work.

I am guessing that polyester wrapped is what we in the states refer to as thermofoil. (??) Yes they are a very durable surface and they clean up very well. While not liked by many, they have their place and can work very well.

From what I am reading, polyester is different than the vinyl used in thermofoil--it is supposed to be heat resistant, and stronger.

I am not familiar with this. I hope some other folks comment as I would like to learn about it as well.
