    I tested a bungalow last year, where no membranes and air tight tapes have been installed when it was built in 2008. The test ended with an air change rate of 2.3 1/h and an air permeability of 2.06 m³/m2h at 50 Pa differential pressure. I even left the cooker hood and one wall vent open, because I wanted to see the performance under real conditions by living in this house myself at this time.

    The top ceiling and the sealing around the windows aren´t the biggest issues for the air tightness in a semi D. The most air infiltrates through your ceiling between the two floor levels, because the most houses in recent years have nice details inside this area as shown in the attached photo.
    Fascinating to see that details. Would you seal all of those gaps with cement, electrical cables holes and all?

    All the gaps on the photo have been sealed with standard foam & taped with air tight tape afterwards. Also the block was covered with hard coat.
    With the materials and technologies nowadays, I´m using air tight foam and air tight paint to get such details sorted.

    I was reading this old thread and I am interested in this detail a lot. I imagine in this house there is a drylining? When you seal these holes in the concrete wall is there any risk of any problems with moisture, because aren't you moving the airtightness and vapour layer back? I am asking as a real noob.
