Laying laminate floor on suspended wooden floor

[ollyfiestakiller]

Hello

I would like to know if I need to put any air vents into a laminate floor if I lay it over a suspended wooden floor.

It is ground floor, and there is air bricks from the outside to under the floor. I can feel a small draft coming from cracks imbetween the floor boards.

My concern is that by the time I put the under floor lining and then the laminate that it will limit air circulation and may cause a dry rot issue

Thanks in advance

there is no problem putting a laminate floor down on top of any type of floor.

for wood floors it is advisable to use the thicker underlay (ie not foam) it’s sort of like a soft mdf about 4mm thick.

the air vents that exist allow what's called the under floor void to be ventilated. this relies on air passing in & out of the vents. it does not rely on any air passing through the floorboards.
