Taping Kingspan K103 insulation floor boards?

[revelation]

Hi all. 
 

We are laying kingspan K103 insulation boards before putting out UFH pipe on top. 

Normally if it’s a foil face board you tape up all the seams and joins. But the K103 that kingspan recommend is a paper faced board.  Is it best to leave it as it is or to still tape it up? 
 

regards.

Are you putting a thin membrane over the top to stop screed getting in the gaps. 

 

Is it liquid screed or traditional ?

Yes. We have 1200 gauge DPM going over the insulation the will staple our pipes down to it.

Follow the kingspan  installation instructions on their website.

1200gauge, what’s that for ?

have you got a dpm under the insulation?

the membrane that goes on top is just very thin polythene it’s not a dpm 

 

buy the thinnest clear polythene, then you can see your kingspan as you staple it, avoids trying to put a staple in a join and them pulling out. 

 

As @ADLIan said what does it say on kingspan site. 

 

I would try try to do two layers not one then you can stagger joins.

We already have the 100mm already so will be going ahead with that. I couldn’t see anything on the king span instructions.
