I have ghosts in the house

[scottishjohn]

all house is UFH

 

but the upstairs was done with cut out polystyrene panels  that they pushed the pipes into 

 

  in the room with ghosts  the supply to an ajoining bathroom and dressing room pipes also run around the perimeter

 

sometimes when things go on  I get noises downstairs like someone is walking about

 

on a creaky floor 

 

I am guessing it is the panels moving

 

 when I told the builder and suggested that maybe the panels should have been stuck down -- he assure me -- as you would expect  that they are not supposed to be stuck down --according to maker

 

another lie i presume?

 

impossible to fix now as there is self levleling layer  and stuck down lvt on top

Ours needed to be stuck down with Rapid Bond, a polystyrene safe spray. I'd be very surprised if any polystyrene boards could be dry laid, they're really weak, just a few mm, where they're routed out.

 

Can you ask the board manufacturer?

 

I'm guessing you only have a few mm of leveling compound over?
