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?

what ever the casue and some more investigation since i posted 

tells me the cement board that are laid over the piping sheets --to act as heat sink  should also be glued together with a special foaming type adhesive which allows for movement 

 

 so the solution is not one i want to contemplate --ripping it all up and doing it the right way--i cannot see the builder doing it and cost to do would be very high 

 

new lvt -- new self levelling and cement boards etc 

-

i think i will have to live with my ghosts

I'd also be reluctant to do anything drastic and expensive, hopefully the whole floor will float but stay flat and you'll get used to the creaks.

 

One possible explanation might be a lack of expansion gaps around the edges of the room, so if you do ever need to investigate further I'd start by taking all the skirting off before doing anything to the floor itself

all skirtings were fitted after cement board and self leveling -but before LVT-- so the grinder did not damage the skirtings

i ma guessing there is too much of a gap inthe poly/pipe  boards and that why they are moving -- 

 

all guess work
