Thank you @Marvin, we will take note of your advice when putting in insulation.

Thank you @Chanmenie, appreciate you contribution

Thank you @JohnMo for the kind advice, we will feed this to the designer to update accordingly.

We are having MVHR installed as part of a new selfbuild project. The designer is proposing Zehnder Comfoair Q600 MVHR as per attached. The Zehnder Comfoair Q600 will be installed within the house as shown on the drawings We are having a cold roof with insulations at ceiling with 100mm across then 400mm over. Our questions are around air tightness and also not compromise on insulation. Do we need to run the ducts o the ceiling then run the 500mm insulation on top of the ducting? Any advise would be appreciated. Many thanks

Thank you John and Nod for the response. will the insulation not limit the amount of heat transfer up to the first floor please?

We are having a new self build project with ground floor underfloor heating with 75mm screed top. I will like advise on the FF ufh. We have a POSI joist for first floor. is First floor ufh required at all? If we decided against ufh for first floor as I have seen on several topics, do we need to add insulation below joist please? We are thinking insulation below joist will stop heating from ground floor to flow upstairs in our lay man thinking. We will appreciate a kind advise as we are at the stage of making this decision. Many thanks Olu

We think we need cased pilling, we will need mini piling machine due to site access
