Airtight membrane on sleeper walls for passivhaus

[Barny]

Hi

 

This feels like a stupid question. We have block and beam floor with sleeper walls standing up. Just putting the airtight membrane in before putting extra insulation on top. I am assuming I need to cover the sleeper walls in membrane and tape to the membrane on the floor? This detail is not on my drawings from architect.

 

is this how others have done it? Like a really complicated Christmas present!!

whats going on top of your block =beam floor ?

UFH ?

If so you will have plastic sheeting ,then insulation  , then screed

 

that sheeting will come up above finished floor level and can join to air tight membrane on stud walls 

I am guessing sleepr walls come to to where you start stud walls ,

so ne big black plastic sheet across beams and up the sleeper walls  and under the stud walls  ,then insulatrion UFH piping and screed

your finished floor will be at top of sleeper walls
