If you want termite proof kitchen cabinet, then get the aluminum type. Sure to be termite proof. 

The so called treatment to prevent termite in the material itself. How will it affect your health as you will be placing your food, utensils, etc inside the cabinets. If it is strong enough to kill the termites, am sure it is also strong enough to affect your health; if it doesn't kill.

SORRY to tell you !! there's no such 100% termite proof for melamine board as far as I know........ pls becareful for the sweet talk of the respective salesman ..... as someone said the aluminum carcass cabinets will give u 100% termite proof solutions..... others like green layer is not !!! it's a type of chemical to make the board become more water resistent (not waterproof) compare to board withour the green layer/chemical....... but i still can accept if the salesperson told u it's chemical will not attracts termites rather than termite proof !!! BEWARE 

the greeny thing are for Water Resistant from what i know...

Yes, it happen that there are such materials, I am personally going for Fibre board for KC as my brother using as well. It is water proof, anti termite, heat resistance, my contractor show me on the spot, burn the fiber board with his lighter and nothing happen on the board, he showed my bro the board rendam inside water 1 week, nothing happen as well, but of course it will be more costly than typical KC using wood one:)

Yes, which mean the green layer are mix with wood chips

OK, fibre board is another type of material which i agree as per your post...... TS saying it's melamine board so as far as melamine board concern mine above comments is FIXED. 

Can I tumpang this thread??? got a question about the melamine as well...

does anyone know whether most kitchen supplier follows the grain of the melamine when they install?
