Which appliances need barrier above them??

[Grendel]

I've got an oak block worktop from worktops express. About 40mm thick.

They advise a moisture barrier stuck to it's underside where you have a washing machine, oven or dishwasher. They talk vaguely about heat and moisture.

 

Is a barrier needed above a fridge with a small freezer compartment?

 

thanks

Nope - just things like dishwashers although a better method is to oil the underside too with Osmo Top Oil before the appliances are fitted as it stops moisture getting into the wood.

I am not sure oiling it once will provide a lifetime barrier. Metallised foils are better as they are impermeable and deflect heat away as well.

Miele lab machines come with the deflector in the install kit.

Most dishwashers come with a deflector plate which is to be nailed into wood/laminate worktops. Then tend to corrode with time so its better to use the metal foil and the deflector as belt and braces

 Agree - I was suggesting oil plus the barrier rather than just oil (probably wasn’t clear)
