Laminate thickness with Wunda overlay UFH

[Rob99]

I'm fitting Wunda UFH downstairs on top of an insulated screed with laminate boards on top throughout (did want engineered wood but don't have the cash!!).

 

My question is what thickness of laminate will be ok? We have seen some in the colour and finish we like (we've looked at hundreds as we're really fussy!) but it is only 8mm rather than the 12mm we have previously assumed would be the minimum.

 

We have some heavy furniture and an american fridge/freezer etc and I'm worried that 8mm laminate might be too flexible and the wunda boards will end up getting compessed under the heavy items.

 

Any thoughts?
