Do I need a diffusion barrier for my KASKER, MÖCKLARP or LOCKEBO worktop?
No, you don't have to.
You don't need to install a diffusion barrier on quartz composite, high-pressure porcelain or glass composite countertops because they are completely solid and can withstand moisture from the dishwasher and oven.
When you purchase a dishwasher from us, a diffusion barrier is always included with the machine.
