5/8 melamine for carcass1/14
How is the 5/8 melamine for strength for uppers and lowers? I know it's heavy and that's not great.
I typically use 3/4 prefinished ply for everything except normal drawers.
I have only used mdf for door panels and my vacuum table.
Nice thing about the particle board is it's stable, dimensionally accurate and stiffer than MDF.
Like you said it is heavy.
It'll work for cabinets. Certainly not my favorite as I'd prefer plywood. But 5/8" will work.
16mm(5/8) melamine is pretty much the worldwide standard for kitchen and closet cabinets. They use 16mm for everything. sides, tops/bots, backs. Drawers are some variation of full melamine or steel sides with integrated slides.
Its all 32mm euro cabinetry. You would be surprised how much weight a 16mm melamine particleboard shelf will hold in a pantry. The other trick is to simply put in one more vertical support(cheap) and it reduces the self spans.
Another detail to consider is your hardware.
You are likely using a 0mm hinge mounting plate with 3/4" thick sides to get the door reveals and overlay you want (1.5mm reveals with 3mm between doors).
When using 5/8" (16mm) sides, you will want to use 3mm hinge mounting plates to maintain the same reveals and gaps between doors. This way, you can keep your hinge edge bore distance the same regardless of the side material thickness.
If using undermount drawer slides, 1/2" and 5/8" drawer sides take the same slide whereas 3/4" thick drawer sides require an altogether different slide model.
For residential work, almost anything is fair game and 5/8" is very common but for commercial & institutional casework , the AWI spec calls for 3/4" thick sides. I would also check availability through your local distribution supply chain. In many markets, 5/8" is far less readily available than 3/4" (colors, patterns & wood grains selections).
Thanks for the help gentlemen.
Dennis you were right about my supplier not having much 5/8, not much demand for it.
