Can I use battens to put my my engineered floorboards on ?

[hughsie]

I suppose the question is in the title !

 

[JohnD]

what are you going to put the battens on?

 

[mointainwalker]

...........and what are you going to put in between them ?

How thick is your flooring ?

 

[hughsie]

onto concerete slab. I was thinking of filling the void with some insulation. I thought that I would let the 'old' but dry floor breathe whilst allowing sufficent gap between the floor and the boards. Throught about putting a DPM under the battens but a little worried about any damp being moved to the walls and creating a problem there that I dont have now.

How thick is your engineered-wood flooring ?

 

[hughsie]

14mm Thanks

 

[WoodYouLike]

14mm is not load-bearing so therefore cannot be installed directly onto joists or battens without any decent support.
Your boards have to be at least 18mm

 

[hughsie]

Bugger. Is there an underlay that is capable of taking a load and which is think enough to remove a slight flooring variation. Preferably one which can be but down on a concrete screed

 

[mointainwalker]

PIR insulation board might work here as you want to insulate anyway and it is pretty tough. Would be necessary to get very good match batten/PIR height otherwise flex might destroy the floor.

I am not certain about this, so wait for one of the professionals to comment/

Thanks Mountainwalker - all advise greatfully received. Ive been looking at Kingspan Kooltherm Floorboard (www.insulation.kingspan.com/uk/k3.htm). This seems like it might do the trick ?

 

[chappers]

how big are the variations maybe consider self leveling the floor first.

 

[hughsie]

Chappers - They're not too bad and I have thought about leveling. With this floor board from kingspan I thought I might be able to pack in areas that need leveling ?

Plywood?

 

[hughsie]

Plywood?

Yeap - thought about ply, my only fear in the back of my mind is this little damp issue - thats why I thought of the kingspan. The specific product is water resistant but has the same properties of plywood i.e. is structural. Its also an insulation. Thanks for your reply though

 

[rebelbuttmunch]

I put down a layer of plastic sheeting under the ply to prevent moisture.
